The Role of Solar Charge Controllers in Protecting Batteries and Optimizing System Performance

by vemcoblogs -

If you are a solar PV system owner, you must be aware of the critical accessories that are necessary for the health of your system. One such equipment is a solar charge controller which regulates the charging and discharging of your batteries and also controls the power output. VEMC is the leading solar energy company based in Mumbai and in this blog, we tell you about the role that a solar charge controller plays in protecting and enhancing the performance of your solar power system.

Functions of solar charge controllers

  • Overcharge protection: 

For starters, a solar charge controller protects your batteries from overcharging. As soon as the voltage exceeds the protection voltage, the battery is automatically disconnected. 

  • Deep discharge prevention: 

Converse to overcharge protection, solar charge controllers also prevent deep discharge of your batteries. When the voltage of the battery falls below the over-protection voltage, the solar charge controller turns off the battery output to prevent deep discharge, only to restore the power supply when the battery is recharged.

  • Battery health monitoring: 

A solar charge controller is connected to the same battery terminals and can therefore keep track of the voltage to determine the state of the charge. By constantly monitoring the voltage of the battery, a solar charge controller keeps up-to-date about its health

Types of charge controllers and their suitability

Lets now talk about the two main types of solar charge controllers and the scenarios they best fit into.

  • Pulse Width Modulation (PWM) controllers: 

These are traditional solar charge controllers which operate by connecting directly from the solar array to the battery bank. These controllers are smaller and are suitable only to operate at battery voltage. These must be used with arrays matched with battery voltage.

  • Maximum Power Point Tracking (MPPT) controllers: 

These, on the other hand, are more advanced as compared to the PWM controllers and operate at maximum power voltage. As a result, the output produced is maximized which is great in cold conditions when the voltage of the solar array is much higher than the battery voltage.

Using proper settings for maximum energy harvest and battery lifespan

The right charge controller settings can bring rich dividends when it comes to power output as well as the lifespan of your battery. Different types of batteries work well with different settings. Some of the most important settings that need proper configuration for best results are:

  1. Battery floating charging voltage
  2. Battery over-discharging protection voltage
  3. Battery over-charging protection voltage
  4. Charge controller capacity
  5. Maximum charging current
  6. System voltage

If you’re a solar panel owner, you must make sure you have a quality solar charge controller in place to have maximum harvest and also prolong the working life of your batteries. For more information

Dewatering in Construction

by vemcoblogs -
Kirloskar water pump dealer (1)

Excavation is a huge part of construction and water logging on the sites is a very common problem. To ensure smooth progress of the project, it is necessary that you manage the groundwater well. However, a number of different dewatering techniques are used, each suitable for a certain set of conditions and project specifications. VEMC is the leading Kirloskar water pump dealer in Mumbai, and in this blog, we tell you all you need to know about dewatering in construction.

Types of dewatering methods

  1. Subsurface drainage: 

This is a drainage method which helps remove water that has percolated into the subgrade. It is used in areas that have a very high water table or receive incredibly heavy rainfall. Subsurface drainage typically has a permeable base to remove water rapidly, a pipe collector system to convey the liquid away, and a filter layer to prevent the clogging of drainage.

  1. Sump pumps: 

This is one of the simplest and most cost-effective methods of dewatering. It involves digging pits in the drainage area to collect water which is then removed by using pumps.

  1. Wellpoint systems: 

A number of small wellpoints are installed around a site. These are connected with a central header pipe which has a vacuum function. Wellpoint systems are great for lowering the groundwater levels and facilitating construction work by creating a dry area.

Selection criteria for dewatering methods based on project specifics

The working conditions and project demands can vary from one construction site to another. The choice for dewatering methods must be made accordingly. For instance:

  • In conditions where there’s heavy rainfall, high water table or deep permeable soils, subsurface drainage can be the best option. It is also useful to drain heavy and poorly drained soils, or those that might have an impending layer at some depth, say clay.
  • In case of construction sites with shallow excavations and low-permeability, sump pumping can be the most feasible and cost effective method to remove water. However, it carries with it the risks of sudden collapse or erosion. 
  • In case of shallow excavations or fine-grained soils with low permeability, wellpoint systems can be the method of choice. It is quite cost effective and also easy to install. 

Environmental and safety concerns

Dewatering involves significant environmental and safety risks. For example, uncontrolled dewatering can deplete the groundwater of an area. Likewise, it can also cause increased sediment levels in waterways. In cases when seasonal conditions add more surface water to work sites, unmonitored dewatering can have an accidental impact on the environment.

Dewatering could be a dicey activity. To make sure environmental and safety risks are averted, builders must follow proper guidelines. For more on which dewatering method to choose for your construction site, and how to ensure environmental and personal safety, feel free to call us on 022 43436655 or email us at marketing@vemc.co.in.

Understanding Air Compressor Discharge Pressure

by vemcoblogs -

If you’re an air compressor owner, you must be acquainted with some of the basics of your equipment. Discharge pressure is one of the most relevant notions that significantly impacts how your air compressor performs. VEMC is one of the leading air compressor dealers in Mumbai, and in this blog, we take you through all you need to know about discharge pressure.

Definition and importance of discharge pressure

Discharge pressure simply refers to the air pressure at the output end, that is, the discharge flange of your compressor. Maintaining optimum discharge pressure is necessary to ensure maximum levels of efficiency and productivity. However, higher than required discharge pressure could cause wastage of energy as well as damage to the system. This is because of the rise in temperature leading to metal fatigue of valves and thermal stress on lubricants.

Factors affecting discharge pressure

Discharge pressure of an air compressor is quite dynamic and a number of factors affect it. Some of these are:

  1. Size and speed of the condenser fan
  2. Size of the discharge line
  3. Condition of the condenser coil
  4. Leakage of air
  5. Cooling effect by oil, water , etc.
  6. Rotational speed in case of a screw compressor
  7. Voltage and frequency of the power grid
  8. Suction temperature and pressure

Impact of discharge pressure on system performance and efficiency

For starters, discharge pressure directly impacts the air flow of a compressor, and the simple Boyle’s Law equation can substantiate this. 

P1 x V1 = P2 x V2

However, compressed air isn’t free and with every unit rise in discharge pressure, there is a proportionate rise in energy consumption as well. In fact, it is widely believed that for every 2-psi increase in pressure, the energy consumption increases by 1 percent. So while increase in discharge pressure does boost your performance significantly, it also reduces the efficiency due to overconsumption of energy. Besides, higher levels of discharge pressure can also cause leaks in the system and reduce the distribution of the compressed air, while reducing the lifespan of the air compressor in the long run.

Optimal discharge pressure settings for different applications

It is quite clear that operating an air compressor and deciding the right discharge pressure requires  some amount of nuance. There is no on-size-fits-all for every application that you use your compressor for. Industrial applications usually require a pressure of 100-200 psi while if you’re using the compressor for domestic use, anything between 90-150 psi should be enough. Pneumatic tools like nail guns require a pressure of 90-100 psi while sandblasters and spray painters would typically need 120-150 psi.

Discharge pressure seems to be a straightforward notion. However, to ensure you get the maximum out of your air compressor without wasting energy, you must operate it at the right levels of discharge pressure.

Air Compressor Dryers: Why They are Essential and How to Choose One

by vemcoblogs -

Air compressors find use in a number of industrial applications such as spray painting, packaging and drilling. But a common issue in air compressors is the accumulation of moisture which could be problematic for a number of reasons. This issue can be dealt with using the right kind of air dryer. VEMC is one of the leading air compressor dealers in Mumbai and in this blog, we tell you everything you need to know about air compressor dryers.

Why moisture in air compressors is problematic

Condensation of humidity inside an air compressor is a common issue and can appear in pipes, filters and other machinery. This can cause malfunction and breakdown of the equipment using the compressed air. Over the longer time horizon, it can be a cause for corrosion in the metallic parts. It is especially worrying if you are using the air compressor in packaging as the moisture can lead to the growth of moulds and cause spoilage of packaged items. To get rid of the moisture, air compressor dryers are essential accessories for your equipment.

Types of air dryers

Air compressors dryers are available in a number of variants each suited for a certain set of operations:

  1. Refrigerated air dryers: 

These air dryers condense the moisture in the air to very low temperatures, thus removing it and allowing the compressed air to proceed ahead to the attached tool.  These are available in cycling and non-cycling variants. The former supply variable cooling to match the demand while the latter supply constant cooling irrespective of the demand. Refrigerated air dryers are best suited for manufacturing and service applications but not for highly sensitive ones where even a little moisture can be problematic.

  1. Desiccant air dryers: 

These operate by desiccating the air using hygroscopic materials like silica gel or activated alumina. A twin-tower drying system is typically used both chambers of which contain desiccant materials. These air dryers are best suited for moisture-sensitive industrial applications such as healthcare, packaging, fabric manufacturing , etc.

  1. Membrane air dryers: 

These use specialised membranes to filter moisture out of the compressed air. The microtubules present in the membrane retain water while the dried air is allowed to pass through to the required application. These types of air dryers are best suited for applications such as food processing, dehumidification and gas separation. 

Choosing the right air dryer

Your choice of air dryer depends upon your specific needs as listed above and also your budget. For standardised functions, say in manufacturing, cost-effective air compressors like non-cyclic refrigerators are good enough. However, if your business applications are extremely moisture-sensitive, it is best to use slightly more expensive but highly effective desiccant air dryers.

The ABCs of Air Compressor Accessories

by vemcoblogs -

Air compressors are the go-to equipment to generate power for a number of tasks in industrial as well as domestic settings. These include spray painting, drilling, cleaning etc. However, air compressors can offer optimum performance only when the accessories are functioning well. VEMC is the leading air compressor supplier in Mumbai, and in this blog, we acquaint you with the ABCs of air compressor accessories.

Types of accessories

  1. Filters: 

Air compressor filters are important to remove dust and debris and push out only clean compressed air. Their role is even more important in case you are using your air compressor in sensitive work environments like food processing. Rotary screw air compressors have three filters: an oil filter, an inlet filter and air/oil separator. While on an average, filters must be replaced every 2000 hours of service, they may need even more frequent replacement in dirtier conditions. Replacement helps prevent the oil from becoming contaminated and also the premature failure of the parts.

  1. Regulators: 

Air compressor regulators help control the air pressure in a pneumatic system. This ensures that the air compressor operates safely and at optimum levels of efficiency. 

  • General purpose regulators: These are best suited for use in industrial settings and operate above the atmospheric pressure.
  • High pressure regulators: These have an inlet pressure of 1000 psi.
  • Dual stage regulators: In these regulators, the liquid flows through a succession of chambers to deliver constant pressure.
  • Point-of-use regulators: These regulators are attached at or near a tool such as a pneumatic drill.

3. Lubricators: 

Air compressor lubricators help reduce friction between parts of an air compressor and dissipate the extra heat generated. An air compressor lubrication system comprises of a crankcase sump, strainer, filter and cylinder lubricator. The lubricating oil is contained in the compressor crankcase. A preset mark on the crankcase indicates the level of lubricating oil that must be present in it and thus helps at the time of replenishment. 

4. Valves: 

Air compressor valves control the in and out-flow of air or oil in a compressor.

  • Intake valve: As the name suggests, an intake valve enables the air to enter the compressor. This air is then directed to the compressor head where it is compressed.
  • Minimum pressure valve: It is located at the outlet above the oil-gas separator. It acts as a buffer to control the flow rate of the gas and prevent damage due to high-speed airflow.
  • Safety valve: This is important for the safety of the air compressor as it discharges some gas as soon as the pressure exceeds a certain level.

Choosing the right accessories

If you are looking for accessories for your air compressor, make sure you only choose the original ones. Only original accessories can guarantee optimum performance and a long service life.

Comparing the Different Types of HVAC Pumping Systems and their Suitability for Various Applications

by vemcoblogs -

For starters, HVAC stands of Heating, Ventilation and Air Conditioning. HVAC systems help in maintaining and moderating indoors environment, that is, humidity, air flow, temperature and air filtering. At the backend of the operations of HVAC systems, pumps play a critical role. VEMC is one of the leading water pump dealers based in Mumbai, and in this blog we compare the different HVAC pumping systems for your use.

Types and features of HVAC pumps

In systems which have a significant storage capacity, constant speed pumps are a better choice. The right kind of constant speed pump can in fact run at high efficiency as shown in the graph below:

2. Variable-speed pumps: 

These pumps are simply equipped with a Variable Speed Drive (VSD) to produce variable speeds. In case you are pumping water across flat ground, most of the energy is consumed in overcoming friction. Such a system requires a variable speed pump.

3. Single-stage pump: 

These pumps have one impeller that rotates on a shaft within a pump casing. It produces flow on being driven by a motor and has one of the simplest designs. They are quite useful in HVAC systems as they are close-coupled which means that the pump and the motor are separate units. These pumps are less sensitive to impurities in the liquid.

4. Multi-stage pumps: 

These pumps have multiple impellers and diffusers and can therefore pump liquid at much higher pressure than single-stage pumps depending on the number of stages and speed. Each stage is interconnected and feeds pressure into the next one thus cumulating the overall pressure significantly. These pumps can be installed both horizontally as well as vertically and can thus be adjusted well into your HVAC systems.

Choosing pumps for your HVAC system

The most common pump used in HVAC systems is the centrifugal pump available in circulator, single-stage, multi-stage, end-suction and vertical in-line variants. Which pump you choose for your HVAC system depends upon the unique needs of your building such as capacity, pressure required, space available , etc. 

For example, circulator pumps are used in systems which require low pressure and low capacity. These are typically under 150 gpm. End-suction pumps on the other hand are great for systems with capacities of up to 4000 gpm and head of 150 feet. Likewise, if your building has space constraints, the best option for you is the close-coupled pump that occupies less floor space. In case you require a lot of pressure, multistage pumps which build pressure incrementally with each stage are perfectly suited for your operations.

If you are looking for guidance for selecting the perfect pump for the HVAC systems, your search is over. Just get in touch with our experts by calling on 022 43436655 or emailing us at marketing@vemc.co.in. We are the leading water pump dealers based in Mumbai, with over 70 years of rich industry experience in pumping across a diverse client base.

The Importance of Solar Energy in Reducing Maintenance Cost of a Building

by vemcoblogs -

Solar energy is one of the most preferred alternative sources of energy. It is especially gaining popularity among Indian users given the abundant sunlight that the tropical country receives coupled with the facility of net metering that allows owners to reduce their electricity bills significantly. But solar energy has a more indirect but significant benefit for your building as well. VEMC is the leading solar energy company based in Mumbai, and in this blog, we tell you how your rooftop solar system can help reduce the maintenance cost of your building.

Reducing wear and tear

Solar panels are installed with either ballasted racking system or roof clamp system, neither of which require you to drill holes in your roof. Rather than damaging your roof, solar panels help protect it by offering an additional protective layer on top of it. They protect the roof from the harsh rays of the sun as well as inclement weather conditions like hail, snow and heavy rains. The overall effect of rooftop solar panels is reduced wear and tear of your roof.

Minimised dependance on traditional energy sources

Energy amounts to a huge cost in maintaining any residential, industrial or office building. Rooftop solar systems help reduce the dependence of your building on traditional sources of electricity. Besides, on-grid solar power systems equipped with net metering facility also help reduce your electricity bills by exporting excessive electricity to the grid.

Simpler maintenance needs

Maintaining your solar panels is quite simple and cost effective. For starters, solar panels sold by VEMC are made of durable material with an average life-span of around 25 years. But the maintenance is quite easy as there are no moving parts and these panels rarely encounter any technical problems being so simple in design. All that is needed is some occasional sprinkling of water and a quick wipe to keep the dust and debris off the panels and enable them to function at peak productivity levels.

Case in Point: Godrej Coliseum

Godrej Coliseum is a mammoth commercial complex located in Sion, Mumbai and provides office space to shipping, pharmaceutical, BPO, auto and telecom businesses. It is spread across an area of around 83 million square feet and offers amenities like escalators, car-parking, fire-fighting systems and advanced security. To power such an enormous commercial facility, VEMC installed mono-crystalline modules and Delta inverters with a total capacity of  75 kW. In coordination with the DISCOM, the facility of net metering was also installed. Post-installation feedback revealed that the client saved upto 1.2 lakh unit of electricity annually which amounted to Rs. 12 lakh.

Rooftop solar panels are a blessing when it comes to reducing the energy and maintenance costs of your building.

The Significance of Corrocoating in Industrial Applications

by vemcoblogs -

Corrosion is one of the most problematic issues with industrial equipment like pumps, valves, pipes and tanks. But corrocoating is one technique that can help you combat it effectively. Corrocoating has significant use in chemical and wastewater treatment plants as corrosion can drastically reduce the working life of equipment as they are exposed to moisture. VEMC is one of the leading industrial water pump suppliers in Mumbai, and in collaboration with Kirloskar Corrocoat, undertakes turnkey projects for coating a wide range of electromechanical equipment.

Types of corrosion

Here are the main types of corrosion found in electromechanical equipment.

  1. Uniform corrosion: This type of corrosion occurs over the entire surface of a metal. Although it is one of the most benign forms, nevertheless it requires prevention as well. 
  1. Pitting corrosion: Being hard to predict, detect and characterise, this type of corrosion can be highly destructive. As the name suggests, it leads to the formation of vertical holes or cavities on the surface of a metal. This type of corrosion can be caused due to local break or damage in protective coating. It can cause sudden failure of equipment despite relatively low loss of metal.
  1. Crevice corrosion: It is also a localised form of corrosion usually resulting from stagnant microenvironment with a difference in concentration of ions between two areas of a metal. It affects shielded areas like under washers, gaskets, bolt heads , etc., with limited oxygen supply.
  1. Inter-granular corrosion: It is caused by impurities present at the grain boundaries and occurs along or adjacent to these grains. While the bulk of the metal remains intact, it affects its mechanical properties.
  1. Galvanic corrosion: It is the degradation of metals near the joint which occurs when two electrochemically different metals are in contact in an electrolytic environment. 

Benefits of corrocoating

  1. Increased lifespan: With corrocoating, users can expect a longer lifespan for their electromechanical equipment which reduces the need to replace or repair them frequently. This also reduces the waste that entails due to replacement of old equipment and is hence in line with the concept of circular economy.
  1. Cost savings: By avoiding frequent breakdowns due to corrosion, users can save significant amounts of repair and maintenance costs.
  1. Reduced downtime: Corrosion can impact some of the most critical pieces of equipment in your business facility leading to sudden and unforeseen downtime. This can be successfully avoided with protective corrocoating.

Case in point: MCGM Complex Pump Corrocoating Project

VEMC has undertaken a number of large-scale corrocoating projects in the past. In 2015, we corrocoated the crucial Municipal Corporation of Greater Mumbai (MCGM) Complex Pump at Bhandup. The pump was affected by heavy pitting corrosion inside the casings. It was taken to KBLs Hydraulic Research Centre where it was blasted, coated and inspected. The corrocoating didn’t just ensure the protection of the pump from corrosion but also showed instant results in terms of better efficiency, input power and head.

Pump Energy Audit: How to Save Big on Energy Consumption

by vemcoblogs -

Energy prices are skyrocketing everywhere and if you are a pump owner, you would appreciate how important it is to ensure your pumps operate at optimum efficiency. Whether you’re concerned about your rising energy bills or running a sustainable business, pump energy audits help you meet your energy saving goals big time. We at VEMC are the leading water pump dealers based in Mumbai, and in this blog we tell you all you need to know about pump energy audit.

How Pump Auditing Is Done

A pump audit is a comprehensive and end-to-end assessment of a pump’s performance and energy efficiency and also an exercise to unearth any issues or areas for improvement. The major steps in pump auditing are
System design evaluation: Ensuring the design of the pump satisfies its unique needs.

  1. Performance analysis: Parameters like flow rate, pressure, power consumption, motor efficiency , etc., are measured.
  2. Assessing energy efficiency: Energy consumption patterns are analysed using tools like Variable Speed Drives (VSDs) and other control mechanisms.
  3. Maintenance and reliability review: Lubrication, alignment, vibration analysis and seal integrity are evaluated to test pump maintenance and reliability.
  4. System control and automation: Sequencing, control methods and technology are analysed to detect potential problems.

Factors That Can Waste Energy

One of the main aims of pump auditing is to ensure that your pumps do not consume too much energy. The main factors that are known to waste energy are:

  1. Inefficient pumps: If your pump is old, worn out and has outdated design or technology, it is highly likely that it is inefficient and consuming extra energy.
  2. Improper sizing: Make sure your pump size is suited for the task at hand. If the pumps are too big, it can lead to wastage of energy.
  3. Control issues: Insufficient control methods of the pumps is also one of the leading causes for wastage of energy. Try and test a number of different control methods like VSDs to make sure no energy is wasted.

Some Practical Tips For Optimising Pump Operation

  1. Avoid oversizing your pumps: While slight oversizing of pumps may be good for meeting future uncertainties, it is best to use a pump with capacity roughly equal to the demand of the task.
  1. Trimming the impeller: If your pump is oversized, it is a good practice to trim your impeller to reduce the pressure and flow produced.
  1. Using VFDs: Variable Frequency Drives help automate pump operations like flow and head to match the demand of the application.
  1. Parallel pumping system: Installing a second, smaller pump to match average demand of the application can be a good way to relieve the larger pump of a significant amount of burden.
  1. Limit pipework: Limiting the pipework in the system is a good way to reduce frictional loss and hence save energy. Make sure pipe diameter, length, layout , etc., are also given due consideration.

8 Common Mistakes to Avoid when Installing Solar Projects

by vemcoblogs -

Solar energy is fast becoming one of the most preferred alternative sources of energy. This is especially true of a tropical country like India which receives plentiful sunlight in most parts throughout the year. However, we are still in the early days of our solar journey and a lot of customers tend to make installation mistakes which can later prove costly. VEMC is a leading solar energy company based in Mumbai, and in this blog we tell you about the 8 common mistakes that you must avoid when installing your rooftop solar panels.

1. Understanding energy needs

The capacity of rooftop solar panel must be determined by the energy needs of your home or facility. However, consumers often make the mistake of considering only their current needs. Since solar power system is a long-term investment, you must plan ahead and also build capacity as per your projected needs in the future.

2. System sizing

To meet the energy demands of your facility, it is necessary that your solar power system is suitably sized. You must avoid both under as well as over-sizing of your solar power system. The former can lead to shortages of energy while the latter causes wastage.

3. Placement

Make sure your panels are properly positioned to face the sun maximum possible time for optimum productivity. This is where the skill, expertise and experience of your installer comes into play.

4. Financing your solar project

With a number of government incentives and financing options available, you do not need to finance your solar project all by yourself. All you need is some market research to choose the most cost effective financing option.

5. Obtaining permits

You must obtain a permit from your local power distribution company (DISCOM) before installing a solar power system. Additionally, look for other local body regulations which are mandatory in your locality, town or city before installing the panels.

6. Factoring in maintenance costs

Your solar power system doesn’t just have initial investment costs but also long-term or lifetime costs which customers often overlook when deciding to invest in one. Make sure you speak to an expert and factor in the maintenance costs of your solar power system before making the investment.

7. Avoid scams

With a lot of excitement about solar power systems in the air, customers may be tempted to invest in them by unscrupulous sellers claiming that these systems are money-minting machines. While on-grid solar panels do help reduce your bills through net metering significantly, they are not likely to make you rich overnight.

8. Choose the right installer

Finally, when it comes to installing solar power systems, you must only trust a reliable and reputed seller that has plenty of experience and cutting-edge expertise in the field.

The company also plays a significant role in addressing the problem of water pollution and making a positive environmental impact.

VEMC pumps in wastewater treatment

Cutter and clogging pumps offered by VEMC play a huge role in treating wastewater in urban areas. The water is then recycled and used in homes, offices and factories across cities, thus offering significant reprieve to water-stressed regions of the country.

Cutter pumps: These pumps are equipped with a tungsten carbide blade which cuts down solid and semi-solid waste. This is especially suitable for toilet paper, plastic, rags , etc., and cuts them into pieces of 25 mm each thus preventing clogging of drains.

Grinder pumps: Rather than cutting waste, these pumps grind it in a rotating motion with a blade having multiple teeth. This grinds solid waste into fine powder that can then be discharged easily through drains.

Submersible pumps: VEMCs submersible pumps are corrosion-resistant and light-weight. These are highly energy efficient and are used to displace water from distant or flooded areas and cramped spaces.

Multistage pumps: These pumps have a compact design and are highly energy efficient. They come in vertical and horizontal variants and are used to extract water from areas with limited ground area.

A step towards sustainability

Water shortage is one of the most pressing problems faced by humanity world over. However, the circular economy offers an enduring solution to it through recycling, disinfection and reuse of water. This requires cities and towns to have an elaborate infrastructure that processes solid or semi-solid sewage, transports used water to purification and recycling centres, and finally pumps the cleansed water back into circulation for use at homes, factories and offices. 

At the heart of these elaborate operations are the VEMC pumps mentioned above, specialising in a host of activities from declogging drains to displacing water in large quantities. Most importantly, all of this happens at relatively low energy costs and high efficiency. Besides, VEMC pumps are known to be long-lasting and have little lifetime costs due to low maintenance needs. These features contribute significantly to the circular economy and sustainability of the pumps.

VEMC has a rich experience in project-management and has undertaken a number of projects end-to-end, each with the goal of reducing wastage of water, taking a resolute step towards sustainability.

Importance of High-Quality Fire Panels

by vemcoblogs -

As a business or home-owner, you would appreciate the importance of a fire panel in early detection of an outbreak. Undetected outbreaks can cause immense and irreversible loss of life and property, and a good fire panel can be crucial in preventing this. However, to ensure utmost reliability, you must only choose high-quality fire panels for the safety of your family, employees and property. 

VEMC is the leading Kirloskar fire pump dealer in Mumbai, and in this blog, we tell you why a high-quality fire panel is important.

Types of fire panels

  1. Conventional: These panels use basic technology to detect fire but are still considered quite effective for homes and businesses. They connect sensors and alarms using zone wiring. Sensors are linked in parallel with one or more circuits connected to them.
  1. Addressable: A step ahead of conventional fire panels, the addressable fire panels assign each device an individual address. This enables you to find the exact location of the outbreak in the building.
  2. Intelligent: These are also known as smart fire detection systems. They offer greater flexibility using customer programming of each application and are best suited for accurate and timely fire detection for advanced safety.

What makes a fire panel high-quality?

Fire-panels could be crucial in saving lives and you must only trust the highest quality of component parts. Monitors, flow switches and control valves must be high quality and in good working condition. Only resilient and durable material can withstand the degradation with the passage of time, and provide fool-proof safety during an outbreak. 

Quality can be assessed by certifications that the manufacturers have. The three main standard certifications for fire-panels are provided by LPCB (Loss Prevention Certification Board), UL (Underwriters Laboratories), and VdS (Schadenverhütung GmbH). When deciding to buy a fire panel, look for any of these standards.

Quality however cannot be expected to remain constant. Like all other equipment, fire panels also undergo deterioration with the passage of time, unless maintained regularly and properly. This requires thorough training of the maintenance staff to bring them up-to-date with the latest maintenance practices. Generally speaking, fire panels must be kept clean and visually inspected regularly. VEMC –– a trusted Kirloskar fire pump dealer in Mumbai, can offer more insights on the maintenance of your fire panels.

Evaluating a fire panel system

When buying a fire panel system for your house or factory, you must be mindful of a few factors. In fact, you must have a standard checklist handy to ensure proper evaluation of the fire panels. 

  • Has the fire panel been designed by a reliable company or a qualified professional?
  • Are the equipment and component parts reliable and do they meet quality standards?
  • Is the installation team qualified and experienced enough?
  • Is the fire panel cost effective in terms of the finances and effort required for maintenance in the long run?
