Solar Photovoltaic (PV) Modules – Forecasting Price Levels in India for 2022

by vemcoblogs -

The price of photovoltaic (PV) modules saw a substantial dip from 2010 to 2020 – of about 70 to 80%, thanks to the growth of PV modules and solar power technology both in India and the world. Witnessing a steady average growth of about 25% each year, India had installed more than 40 GW worth of solar energy by December 2020. Interestingly, 55 to 65% of the total cost of the solar project is on PV module solar panels. PV modules are the single most important component of a solar power plant, and through these years, there was a dramatic improvement in their technology. As a result, PV modules became more efficient (measured by the proportion of solar irradiation converted to solar energy), and had better output capacity. 

Trends in 2020

Many expected these downward trends in the industry to continue in the coming years. Several developers even bid for projects under government tenders based on the premise that the price of PV modules would keep declining. On the contrary, the opposite happened. PV module price rose by 7 to 10% over the second half of 2020! From US$0.21/Wp in 2020, it increased till US$0.33/Wp in 2021. This led to industry watchers questioning whether this was a result of changes brought on by the pandemic, or a more permanent tendency that would stay.

Reasons for the Deviation in PV Module Prices in 2020

To set the context, let’s look at some key facts in the solar power industry. For one, China controls over 80% of the world’s solar supply chain, particularly in important areas of raw materials like glass and polysilicon. With this in mind, let’s examine the factors leading up to the subsequent rise in PV module prices:

  • The sudden breakout of the COVID-19 pandemic shifted a major part of the demand from the first half to the second half of 2020.
  • There was a shortage in the supply of polysilicon owing to an accident at GCL- Poly Energy Holdings Limited, a large supplier in Hong Kong, and the outbreak of a new virus in China’s Xinjiang province, another significant supply market. This resulted in over a whopping 50% increase in prices.
  • The transition of technology and slowed down ramp-up capacity further led to a shortage of glass.
  • The price of other essential commodities like aluminium and silver were also driven up.
  • Cost of transportation went up thanks to restricted movement of ships and containers during the pandemic.
  • The US Dollar fell in value against the Chinese Yuan.

Predicting PV Module Prices in FY22

The above chain of events contributed to the surge in PV module prices, and it remains uncertain when the situation will reverse. Issues like the supply shortage of raw materials might get resolved soon, but only if we assume that the pandemic will end shortly. Trends in commodity prices will also influence module prices and have a more long-term impact.

Technology Advancement in the Solar Power Industry

New technologies like bi-facial and 500+ Wp modules are emerging rapidly and will be likely to become mainstream over the next few months. As well, governments are expected to incentivize local manufacturing both globally and in India. These might result in a return to the previous trend of decreasing PV module prices. However, if governments decide to impose trade barriers like duties, prices may increase again. 

Although short-term factors make PV module prices somewhat unpredictable, these are overridden by the more long-term implications of solar power as the most sustainable option of energy. In the long run, PV module prices are likely to diminish to support the mainstream implementation of solar energy.

India’s Solar Energy Market in the Past, Present and Future

by vemcoblogs -

The Past 10 Years – An Overview

India has proved to be a major player in the solar energy industry. In the past decade alone, it has seen an exponential increase in its capacity for solar power. By the end of 2020, the nation had installed a collective base of over 40 GW of solar power, with an annual growth of about 25%. Global factors like reduced cost of PV modules, rising demand and production, and a united commitment to slash carbon emissions also contributed to the growth of India’s renewable energy sector.

Most importantly, regulatory guidelines like duty-free import of Chinese PV modules, minimal duty on quality components from across the world, and the removal of subsidies on commercial and industrial business further led to the opening up of the renewable energy sector. Investment into the green energy industry increased.

Challenges in Solar Energy Today

India’s target of 175 GW Renewable Energy by 2022, (100 GW solar power, out of which 40 GW is powered by rooftop solar) was originally an ambitious but achievable target. Today, our installed rooftop solar capacity is only between 5 and 6 GW.

India had originally set a target to achieve 100 GW in solar energy by 2022, out of which 40 GW was to be powered by rooftop solar. However, its rooftop solar capacity stands at only 5 to 6 GW.

The COVID-19 pandemic caused disruptions in the supply chain, and while these are likely to be resolved in the near future, it fuels uncertainty in the present-day scenario.

India’s commitment to the Paris Pledge by 2030 takes a 3-pronged approach: 

  • 33 to 35% reduction in emissions intensity of the GDP
  • 40% of installed electricity capacity to be renewable energy or nuclear
  • 2,000 to 3,000 MtCO2e of an additional cumulative carbon sink

According to a 2018 report released by the World Health Organisation, a staggering 9 out of 10 most polluted cities in the world are in India! By 2021, the country was found to be the most polluted region in the world. This makes national objectives like transitioning to clean energy, electric mobility and improved energy efficiency not merely idealistic goals, but absolutely necessary measures that must be taken.

What’s Next

India is one of the most rapidly growing economies in the world, and its demand for energy aptly reflects this. Going forward, policies need to include practices that minimize climate risk and improve classification standards to help investors, financial institutions and investors gauge market potential and system-wide risks better.

Some measures that can be implemented to promote the growth of the renewable energy sector include:

  • Removal of cap on net metering
  • The freedom to choose between net or gross metering
  • Standardized long-term open access norms across states 
  • A unified renewable energy policy across the country
  • Minimal time taken for approvals related to connectivity, and net metering

Moreover, technological advancements in the sector like floating solar and solar-wind hybrids are likely to propel the industry further.

The Importance of Reading a Centrifugal Pump Curve

by vemcoblogs -

A centrifugal pump is used to transport fluids by converting rotational kinetic energy into hydrodynamic energy. It finds common applications across the food and beverage, dairy, and pharmaceutical processing industries. Reading a pump performance curve is important when choosing the pump that best fits your requirements.

A pump performance curve predicts the performance of a pump in terms of its flow and pressure head and being able to read it is imperative to a pump’s performance in the long term. Also, when selecting a centrifugal pump for a new application, you need to consider its composite curve so that its performance matches the one that is most suitable for the system. Generally, a composite curve consists of pump performance and horsepower curves, as well as the required NPSH (Net Positive Suction Head).

A centrifugal pump passes energy onto the fluid and possesses certain flow and head qualities. The pump needs to overcome a necessary level of pressure, and this is what determines where the performance point should be on the curve, and how much flow will be produced. The value of the pressure is inversely proportional to that of the flow. As pressure increases, flow decreases. This shifts the performance point to the left of the pump curve. Conversely, as pressure decreases, flow increases, and the point shifts to the right of the pump curve.

As a rule of thumb, when analyzing a pump curve for a new requirement, it is best to stay as close to the BEP (Best Efficiency Point) as possible. This is the operating point on the performance curve that shows the highest efficiency point for the pump’s impeller diameter. 

There are 8 main pieces of information that you will need to be able to identify on a centrifugal pump curve. They are as follows:

1. Title Box

This contains the pump model, size, speed, and other characteristics of the pump. 

2. Flow

The horizontal axis of the pump curve indicates the flow, so identify the amount needed from the pump.

3. Head

The vertical axis on the pump stands for the head. 

4. Impeller Trim

In some cases, performance points cannot be met with the maximum impeller size alone. This is why centrifugal pumps accommodate trimmed impellers. On the pump curve, the impeller diameters are to the left and the performance for each trim is represented as a bold line across it.

5. Horsepower

The horsepower is displayed as a dotted line across the pump curve.

6. NPSHR

Net Positive Suction Head Required (NPSHR) is the minimum amount of pressure on the suction side of the pump to overcome losses in pump entrance. (This is not to be confused with Net Positive Suction Head Available or NPSHA.)

7. Efficiency

On the pump curve, the efficiency is the ratio of energy delivered by the pump to the energy supplied to the pump. The higher the efficiency, the less energy required to operate for a specific performance point. Pump efficiency numbers of 60-80% are normal.

8. Minimum Flow

A centrifugal pump needs a minimum flow moving through the pump to dissipate the heat that is generated. On the left side of the curve, the minimum flow is indicated by a vertical bold line. Operating to the left of the minimum flow line is detrimental to the shelf life of the pump and is not advisable.

Five Mistakes Not to Make When Choosing an Industrial Air Compressor

by vemcoblogs -

Choosing an industrial air compressor for a specific application is an important task. It is a seminal step, and although it can be complex, it is crucial to get right for smooth operations. Here are five mistakes that are necessary to refrain from making when selecting an air compressor:

Choosing the wrong compressor technology

There are several different compressor technologies in the market including centrifugal, screw, piston, and scroll compressors, and making the right choice best can be confusing. Here’s a guide to help you select the one that fits your requirements best.

  • Piston compressors are ideal to operate in a relatively smaller space where the daily hours of running are low and duty cycles are shorter. If you are looking for a compressor in these conditions that comes with an affordable initial cost, this may be the right compressor for you.
  • Screw air compressors are highly energy-efficient, make less noise, and are easier to maintain. If your tasks are going to need long duty cycles, and the number of hours of running each day will be higher, these can be suitable for you.
  • Scroll air compressors make minimal noise and maintain a fully oil-free environment. They are appropriate for use in places like hospitals and universities.

Picking the wrong compressor size

Selecting the right size for the compressor is crucial for efficient operations. It helps to know the exact measures of operating pressure and the flow of volume in the air compressor for your processes. This will then help you determine the correct size that you need the air compressor to be.

Ignoring your air quality requirements

The application of the air compressor may have a standard air quality requirement. For example, in pharmaceuticals, you may need the air quality to be completely oil-free, while in other industries, the rules may not be as stringent, such as in manufacturing. You can consult an air compressor expert for help with identifying yours.

Not considering the lifecycle costs of the compressor

When choosing an air compressor, bear in mind that a majority of its lifecycle costs are due to energy consumption. This is why it is important to choose a machine that is energy efficient for use in the longer term. Don’t make the mistake of underestimating the total lifecycle cost of the air compressor.

Going with the wrong service provider

Choosing the right compressed air service provider is as important as choosing the right air compressor machine. Make sure to go with a reputed provider that not only supplies OEM parts but also offers quality maintenance and emergency support.

Follow the above tips and avoid costly mistakes when selecting an air compressor!

How To Achieve Efficiency, Performance, And Quality Compressed Air Strategy

by vemcoblogs -

Compressed air is a common source of energy that is used across several industries, including manufacturing. Compressed air can also prove to be quite expensive, often consuming more energy than most equipment in a manufacturing plant. The good news is that compressed air systems can be greatly improved in efficiency, performance, and quality with the right strategy. 

There are three main components of the air compression system that influences performance, efficiency and quality. Let’s take a look at them.

Composition of the air intake

Clean air intake by the system allows the compressed air to move smoothly through it. Contaminated air is impure, so a build-up of it over time leads to wear and tear, and makes the storage capacity suffer.

Temperature of the air intake

The cooler the air, the less energy is required to compress it. The temperature of the intake air determines its density.

Humidity

Moisture can harm the air compression system if it collects inside because it causes the parts to rust. It can also catalyse wear and tear, and leaks while reducing the storage capacity. Making sure the air is dry will more likely prevent such damage to the system.

You can also optimize the design of the air compression system to increase its efficiency. There are three ways to do this:

Cooldown intake air

Since the energy required to compress cool air is less than that for warmer air, you can move the system into a shaded area to lower the temperature of the intake air.

Straighten the path

Sharp bends or narrow delivery lines can increase friction and the number of pressure drops in the system. Implement a straighter path into the system to get higher pressure, thus reducing the overall amount of energy required to compress the air.

Use several small compressors

Larger air compressors consume more energy per unit while working with only a partial load, thus making it inefficient. Try using multiple smaller air compressors with sequencing controls so that you can shut down portions of the system just by turning off some of the compressors.

Other practices that help your air compressor perform at optimal efficiency are:

Maintaining the compressor

Regularly check the air compressor system for any leaks, premature wear and tear, and the build-up of contaminants. Ensure that procedures are in place and train employees to operate the system properly.

Changing filters

Filters make sure that only the cleanest air reaches users. However, these filters may get clogged up with dirt, grease, dust, and other contaminants. Clean them often so that the system does not consume more energy to function due to a pressure drop as a result of clogged filters. You can also deploy longer-life and low pressure drop filters of a size suited to the maximum flow rate.The above practices will go a long way in achieving efficiency, performance, and quality of your air compressor system.

The Role Of Temperature In Pump Selection

by vemcoblogs -

When choosing a pump for your industrial or commercial applications, there are several factors that you need to consider. The role of temperature is a major one, how hot or cold the fluid in the system is, the levels of heat generated by the pump and other equipment, and the particular range required for the operation, being key. So why is the role of temperature so integral to the pump selection process? In this blog, we will outline the ways in which temperature can have an effect on your pump and operations. These are as follows:

Corrosion to construction parts

The temperature of the pump can cause corrosion to the parts or construction materials if you plan to be pumping specific kinds of chemicals. Keep in mind that the hotter the liquid, the more corrosive effect it can have. Thus, it is crucial to check the compatibility of different chemicals and the temperature at which you are going to be pumping.

The pump’s components

With an increase in the temperature, heat gets transferred from gland packing to the bearing through the shaft. This takes a toll on the bearing by shortening its life and possibly even seizing it if the pump’s gland is saturated. This must be avoided at all costs for the pump to be function at peak efficiency.

Viscosity of liquids

Fluids that are affected by temperature can see a change in viscosity during the pumping process. For instance, some become runny when heated, thus influencing how they will be pumped. This is why it is important to understand how temperature can change the viscosity of your product in order to select the right pump.

Expansion of parts

Metal parts can expand at varying rates at high temperatures. So it is essential to finalize the materials of construction while you are choosing the pump itself.

Maintaining the temperature

In certain cases, you may need to maintain a specific temperature or a range of temperatures depending on the application. You can achieve this by preserving the conditions of the flow or use a heating jacket which permits you to maintain higher temperatures. Conversely, you can implement proper insulation in the system to maintain a lower temperature.

Even if you have a suction for the pump that is flooded, it is important to note that you will still have to take the vapour pressure of the liquid, as well as the temperature into consideration in order to ensure that your pump contains the right Net Positive Suction Head Available (NPSHa).For more information on industrial pumps, motors, and other equipment, feel free to reach VEMC on +91-9819907445.

Top 5 Ways To Minimise Your Compressed Air Costs

by vemcoblogs -

Air compression if not done with proper checks, maintenance, and energy audits could turn out to be a fairly costly affair. To control costs of air compression effectively, you must follow a checklist of critical factors. While most of these factors fall under your regular maintenance procedures, some require your special attention. In this blog, we take you through the most important measures meant to control costs while you compress air at your facility.

  • Avoid unnecessary running: The biggest overhead cost associated with air compressors is the energy cost. There is one simple trick that you can use to tackle this upfront: turn it off! Air compressors at most facilities are used during the business hours and yet these are often found running until late evening. This wastes precious hours of electricity and adds to your energy bills.
  • Look for leakages: Leakages in the piping can cause loss of air pressure although the energy expended on compressing the air might remain the same. This means that you are using the same amount of energy but getting lesser work done. It is extremely important to look for leakages due to corrosion, pipe breakage, sludge, and dust particles in the piping regularly. Keeping the piping clean reduces the likelihood of leakages caused by corrosion.
  • Use the right pressure levels: Using the compressor at pressure levels beyond your requirement can cause wastage of energy. One reason for turning up the pressure could be compensating for the loss of pressure due to leakages, clogged filters, and other piping problems.
  • Use proper piping infrastructure: Using the right piping infrastructure that determines the direction and pattern of flow of compressed air is essential. A variety of factors play a role in this regard. Getting the compressed air to the focal point through a short pipe can optimise pressure and reduce energy use. Similarly, reducing the diameter of the pipe can help increase air pressure, work on the focal point effectively, and reduce energy consumption significantly.
  • Recover heat: The heat generated as part of the compression process can be used for a number of productive purposes. These include warming the rooms or producing hot water in washrooms. This could indirectly reduce the energy that would otherwise be consumed by geysers and radiators, especially in colder regions.
  • Ensure proper maintenance: By and large, proper maintenance helps reduce operational costs in more ways than one. In fact, preventive maintenance is less expensive than breakdown maintenance which could result in halting of operations and loss of business.

These insights can help keep a check on the energy, operations, and maintenance costs of compressing air at your facility.

It has extremely robust components that do not deteriorate easily and provide reliable, long-term operations. Being lightweight and highly efficient, these pumps help save plenty of space and integrate into your plant seamlessly. Depending upon their concerned application in the RO plant, these pumps come in a number of sizes. 

Here are some outstanding features of your KVM Pump:

  • KVM pumps are built using engineering polymer impellers and diffusers. This gives the pump excellent resistance to most acids, bases, chlorides and cleaning agents, therefore, diversifying the range of the media it can be used in. This also contributes to great hydraulic stability, reliability, and long-term performance.
  • KVM pumps have a keyed shaft that works in tandem with a machine element and conveys the torque to power transmission components. Positive locking of the impeller means better pump life.
  • The pumps have a fairly wide range of voltage tolerance. They can withstand fluctuations anywhere between 180-240 V and 300-440 V. There are very less chances of motor burning in case of a drastic change in the voltage. The pump by and large has a wide operating range with relatively flat characteristics. This accounts for a stable performance over a longer duration.
  • The motors come with an added advantage of being relatively light-weight. This enhances their portability and makes them easy to handle and integrate into your plant setup.
  • The pumps come with Cathodic Electro-Deposition (CED) coating which makes them resistant to corrosion and early deterioration. CED coating is 5 times as effective as conventional painting and, therefore, means a fairly long pump life.
  • Heat, leakage and wear and tear resistance is ensured by the cartridge type mechanical seal that has high quality graphite and hard alloy. It also contributes to easy maintenance without opening the pump body.
  • KVM Pumps are high on efficiency. They consume less power and can substantially boost your energy savings.

Apart from their extensive use in RO pApart from their extensive use in RO plants, the KVM Pumps also find application in a number of other operations.

A Guide to Solar Panels

by vemcoblogs -

A solar power system consists mainly of solar panels, an inverter, a meter, the consumer unit and the cabling.

The solar panels also called an array, are made up of photovoltaic (PV) cells. The array is usually mounted on a roof so that it is receptive to sunlight.

The photovoltaic cells in it are normally made of very thin layers of silicon and look like black or blue tiles. When sunlight reaches the cells, an electric field gets formed. The brighter the light, the greater the amount of electricity generated.

This direct-current (DC) electricity is then transferred to the inverter, which turns it into alternating current (AC) which you can use for your industry or business.


Let’s take a look at the technology powering the solar panels in more detail.

Monocrystalline (Mono) cells 

Photovoltaic cells can be of different types. Monocrystalline cells (Mono) are made from very high-quality single silicon crystals.

They are highly efficient, perform better in low light conditions than other types of solar cells, and have a lengthy lifespan. 

Polycrystalline (Poly) cells 

On the other hand, polycrystalline (Poly) cells are made by fusing together several kinds of silicon crystals. These are easy to manufacture, are cost-effective, and produce less waste than Mono cells.

However, over recent years, rapid progress in cell manufacturing processes have started to bridge the gap between the manufacturing costs of Mono and Poly cells. In 2018, Mono solar modules comprised 50% of global photovoltaic cell production.

PERC technology

Traditionally, solar cells come with an emitter layer on the front and a dark coating on the back. However,  Passivated Emitter and Rear Cell (PERC) is an innovation that has a dielectric passivation film on the back surface of the cells.

In PERC, the front directly absorbs sunlight while the back soaks in the reflected light, resulting in a higher generation of energy and greater benefits than the traditional solar cells.

It also affords more flexibility with more options for placement of the panels without affecting efficiency. PERC is available in both Mono and Poly cells.

Mono PERC Panels

When Mono cells and PERC technology are combined, the outcome is Mono PERC panels — solar modules of more superior quality.

The initial expenditure gets made up for in energy cost savings. What’s more, a fewer number of panels are required to be installed for the same amount of energy you receive.

They can capture more sunlight even in low light conditions and perform more efficiently than most other types of solar panels in the market. The need for such highly efficient solar panels has led to an increase in demand for Mono PERC panels.

How To Get More Value Out Of Your Solar System

by vemcoblogs -

Businesses today are increasingly shifting to a commercial solar power system, thanks to its improving efficiency over the past few years, lower energy costs in the long run, and in many instances, incentives from the government to switch to a more sustainable alternative with a lower carbon footprint.

While these businesses may be making significant investments in solar panels, many often overlook making the same effort to maintain the efficiency of their solar energy systems.

In this blog, we discuss some of the ways in which you can improve the efficiency of your solar power system and get the most possible value out of it. 

Choose High-Efficiency Solar Module Technology

To begin with, choose the most efficient solar module technology. Solar panels are composed of photovoltaic cells that capture sunlight and turn solar energy into electricity for consumption.

However, solar panels cannot convert 100 per cent of the solar energy they receive into electricity. So, the efficiency of a solar panel refers to the percentage of energy that its photovoltaic cells can actually transform into electricity.

Though solar cell technology has made immense progress over the last few years, not all solar panels function at the same efficiency.

Choose a model with high concentrated photovoltaic cells, that has a good structure and is made with quality material — these are what determine the solar panel’s efficiency. Mono Perc solar panels maintain high industry standards and can be a good option.

Use The Right Inverter

Just as it’s important to choose the proper solar panel, so it is to choose the correct inverter. For your system, get an inverter with a watts rating that’s about the same as your solar system’s watts rating, or maybe a little more.

However, it should not be too much or it will affect the system’s efficiency. Use one of the reputed make to ensure that the system experiences minimal downtime.

Avoid Installing Solar Panels In Shaded Areas

It goes without saying that the solar panels must be under maximum sunlight to capture optimal energy. But shaded areas can affect electricity output even if one photovoltaic is shaded. Remember to analyse and plan the site so that tall trees or buildings do not shade your panels.

Get An Established Epc Company To Install Your Solar Plant

The installation process is a complex and crucial one. Do not compromise and enlist the services of a professional solar EPC company to do the job. If the solar panels are not installed correctly, they will not receive the optimal level of sunlight. 

Clean Your Solar Modules On A Regular Basis

Over time, dirt and dust accumulate on the solar panels. Although solar panels have no moving parts and may not require frequent maintenance, it’s important to clean them occasionally to ensure that they function at peak levels. Temperature and rain can affect them; so get an expert opinion on how often to clean yours.

Track Your Solar Panel Output 

Often, businesses are happy with the initial output of energy from their solar system and stop monitoring it over time. So, a drop in levels can go undetected. Make it a practice to track output and you will be a lot more likely to be able to spot a reduction in efficiency if it occurs.

The Advantages, Application & Components of Butterfly Valves

by vemcoblogs -

Valves find applications in diverse fields of operation to regulate the flow of a liquid in supply systems. Each valve has an indispensable utility courtesy of its design, material, and functioning. Butterfly valves have a special design and unique utilities. In this blog, we talk about the advantages, applications, and components of these valves.

Butterfly valves have a characteristically compact design and are therefore best suited for cramped spaces. Their name comes from the wing-like action of the disc which operates at right angles to the flow.

Advantages

  • A 90° rotation of the handle provides a complete closure or opening of the valve and makes these valves easy and fast to open.
  • These valves require very little material to design and are therefore relatively inexpensive to build.
  • Compared to other valves, they have much lower space requirements and can be used pretty well in tight corners or difficult pockets of a facility.
  • Lesser levels of wear and tear reduce the maintenance costs of butterfly valves.

Applications

Owing to the above-given features, butterfly valves find applications in diverse areas of operations such as sewage plants, chemical processing, and petrochemical plants. Here we list some of the specific activities that they are an integral part of.

  • Cooling water, air, gases, fire protection, etc.
  • Slurry and other services
  • Vacuum service
  • High-pressure and high-temperature water and steam services
  • Compressed Air or Gas Applications

Components

The four components of butterfly valves are body, disk, stem, and seat. Let’s look at each of them in some detail.

  • Body: These valves have bodies that fit between two pipe flanges. The most common body design is the lug and wafer body.
  • Disk: A flat disk fits inside the body of a butterfly valve and acts as a gate to the incoming fluid. When twisting the shaft, the disk rotates and allows the liquid to pass. 
  • Stem: It is the shaft that is held and twisted to make the disk rotate. This is either a one-piece shaft or has a two-piece (split-stem) design. Its material may be selected carefully for purposes of insulation, especially if the valve is directly exposed or submersed in the medium.
  • Seat: The seat of a butterfly valve utilises an interference fit between the disk edge and the seat to provide shutoff. The material of the seat can be made from many different elastomers or polymers to ensure durability and lubrication.

Butterfly valves are thus very high utility devices that often surpass other valves in terms of features, advantages, applications, and cost-effectiveness.

Oil-lubricated or oil-free air compressors – which one should you pick?

by vemcoblogs -

Amongst a diverse set of criteria that you need to keep in mind while choosing your air compressor, the type of lubrication is one of the most important factors. Should you choose an oil-lubricated or an oil-free air compressor for your business operations? Well, the choice largely depends upon the type of industry you are in, the operations you carry out, and the specific role your pump is expected to play in your facility. All these factors are decisive in choosing the lubrication type for your air compressor. But first, you must gain a deeper understanding of both types of air compressors, and then decide whether they suit your purpose. In this blog, we do just that.

Oil-lubricated air compressors

Oil plays a crucial role in these compressors on multiple fronts. Of course, it keeps the moving parts in good condition by reducing unwanted friction. But it also plays the crucial role of dissipating the extra heat generated in the system. Besides, it offers to seal and helps in noise reduction. As these compressors are also available in piston technology, their efficiency, robustness, and ability to work quietly make them effective for a variety of pneumatic tools and accessories. Oil-lubricated air compressors find use in manufacturing, construction, recycling, waste management, and quarrying.

Oil-free air compressors

These compressors do not use oil for lubrication. Instead, their cylinders are coated with a material like Polytetrafluoroethylene (PTFE) which allows the piston to slide in smoothly. Since no oil is involved, the quality of air from these compressors is the same as that which goes in. As such, these compressors find tremendous application in processes where the air must be devoid of moisture or oil vapour. Here is a list of areas that prefer oil-free air compressors:

  • Food & beverage processing
  • Pharmaceutical manufacturing
  • Operating ventilators, surgical machines, inhaled medication systems (only for breathing air certified machines), and other critical equipment in hospitals
  • Semiconductor and electronics manufacturing
  • Automotive spray painting
  • Textile manufacturing

The oil-lubricated air compressors are on average more durable, efficient, and less noisy. These are preferred any day over oil-free compressors if the quality of air is not a precondition. However, regular oil changing is an overhead that comes as part of the package and marginally increases their maintenance costs. On the other hand, oil-free compressors have the sharpest focus on air quality and also have a much lesser carbon footprint. Having the benefit of both these perspectives, you can now make a well-informed choice between the types of air compressors for your facility.

Godrej Coliseum Case Study

by vemcoblogs -

Located in the sub-urban Sion East area of the bustling city of Mumbai, Godrej Coliseum is a magnificently built commercial complex offering retail and office spaces. Businesses like shipping, auto, pharmaceuticals, BPOs and telecom operators in the complex. The building is situated amidst a fairly upcoming residential area and naturally sees a generous footfall of shoppers every day, usually walking in with their families. Spread across 83 million sq. ft, the complex has amenities such as escalators, car parking, beautiful landscaping, advanced security, 24/7 water supply, car parking and adequate fire-fighting systems. 

As expected, the complex is a guzzler of energy and had to be powered with nothing short of a highly reliable and uninterrupted source of electricity. It was VEMC’s reliability and experience that Godrej turned to, and handed over this mammoth 90 kWp project. We were especially expected to ensure that the critical amenities of the building such as lifts, lights and pump loads are kept running uninterrupted. These form the backbone for the smooth functioning of the complex and are also essential for the convenient mobility of the public through it.

The project involved a lot of pre-planning, in that the maps of the electric fittings were thoroughly studied to avoid faulty or redundant wiring. To ensure our work caused minimal disruption in business, we closely coordinated with the client with regard to the vehicle entry and exit, working hours, storage areas, documentary support and other project management matters. We were also mindful of the prevailing DISCOM standards to avoid reworking our designs in case of any issues later. A pre-installation bill of quantities and design approval was issued to the client to provide an estimate of the expenses. Efficient supply chain management and properly scheduled delivery of critical components were imperative for our project management team to keep the project on track, meet deadlines and finish within the predetermined time-horizon. Finally, for the purpose of Net Metering, we coordinated with the DISCOM so that the surplus electricity that would be exported by the solar system of the complex would be offset against the imported electricity from the grid.

The project used mono-crystalline solar modules and inverters of Delta make with a total capacity of 75 kW. Throughout the project, we had the safety of the workers and the fragile equipment in mind and used proper equipment like PPEs, cut-resistant gloves and unloading tools, to handle the equipment. 

Our post-installation feedback revealed that the client had savings of up to 1.2 lakh units of electricity or around savings of Rs 12 lakh annually from this system.
