Heat Recovery from ELGi EG Series Compressors

Air compressors form an integral part of many industrial operations but they are also known to consume significant amounts of energy. In fact, a large portion of the energy input is lost as waste heat. However, this excess heat can also be recovered and utilised for other purposes. Let’s find out how ELGi EG Series compressors, with their advanced heat recovery capabilities, are helping businesses harness this wasted energy. 

Energy Input vs. Wasted Heat in Air Compressors

Air compressors typically consume large amounts of electricity to convert electrical energy into mechanical energy. However, a significant portion of this energy is lost as heat. In a conventional air compressor, this waste heat accumulates in the motor, compressor components, and cooling system. Fortunately, up to 76% of this heat is recoverable and can be redirected for useful applications.

Principles of Heat Recovery in Compressors

The heat recovery process in ELGi EG Series compressors involves capturing and using the waste heat generated during the compression cycle. There are several key components involved in this process such as cooling oil, intercooler, and aftercooler. 

Applications of Heat Recovery

Heat recovered from ELGi EG Series compressors can be used in several applications like:

  • Space Heating: The recovered heat can be used to warm industrial or office spaces, reducing the need for additional heating sources. 
  • Boiler Feedwater Preheating: The heat can be used to preheat water for boilers, lowering the amount of energy needed to bring the water up to the required temperature.
  • Process Water Heating: Many industrial processes require heated water. Using recovered heat for this purpose reduces energy consumption and lowers operational costs.

Cost Savings Potential

The potential cost savings from heat recovery can be substantial. For instance, a business using ELGi EG Series compressors offered by reputed ELGi air compressor dealers may recover up to 50% of the total energy consumption through heat recovery. By recovering even 50% of heat, the company could save up to 38 kW in energy costs. If annual operating hours are 8,000 and the cost of electricity is ₹8 per kWh, whereas the total heat recovery is 38 kW, then the annual savings will be: 38 kW × 8,000 hours × ₹8/kWh = ₹2,432,000 annually. This simple calculation shows how heat recovery can pay off in a relatively short period.

Environmental Benefits

In addition to cost savings, heat recovery from ELGi air compressors contributes to CO₂ reduction. By using recovered heat, businesses can reduce their overall energy consumption, thereby lowering carbon emissions. This aligns with broader sustainability goals and helps companies reduce their environmental footprint.

Integration Considerations and ROI Analysis

When considering heat recovery, businesses must evaluate factors like the initial investment, installation complexity, and compatibility with existing systems. The ROI for heat recovery systems can be realised within 1-3 years, depending on energy usage, system efficiency, and the cost of energy.

Top 8 Causes of Pump Vibration and Practical Fixes

by vemcoblogs -
Pump Vibration and Practical Fixes

Pump vibration is not simply an operational inconvenience—it is often the earliest indicator of mechanical faults or hydraulic instabilities. Left unaddressed, it can reduce efficiency, shorten equipment life and cause unplanned downtime. Understanding the common causes, and their remedies, is essential to maintaining reliable operations.

1. Misalignment (Coupling/Shaft)

When pump and motor shafts are not aligned correctly, vibration increases significantly, putting strain on couplings, seals and bearings. Misalignment is best detected using laser alignment systems or dial indicators. The solution lies in precision realignment to manufacturer tolerances, with alignment checks forming part of routine maintenance.

2. Unbalance in Impeller/Rotating Parts

Impellers or rotating elements may become unbalanced due to wear, corrosion or deposits. This imbalance creates persistent vibration and accelerates wear of bearings and seals. Dynamic balancing restores stability, while regular inspection and timely replacement of components prevent further issues.

3. Bearing Failures

Bearings are especially vulnerable to poor lubrication, contamination or counterfeit spares. Warning signs include elevated temperatures, abnormal noise and rising vibration. Preventive measures include correct lubrication practices, using genuine spare parts and employing monitoring tools to detect early-stage bearing wear.

4. Cavitation

Cavitation occurs when suction pressure falls below the liquid’s vapour pressure, producing vapour bubbles that collapse violently on contact with pump surfaces. Causes include inadequate Net Positive Suction Head (NPSH), obstructed suction lines or poorly designed inlets. Solutions involve improving suction conditions, ensuring adequate liquid levels and designing piping to promote smooth flow.

5. Hydraulic Instabilities

Problems such as internal recirculation or resonance generate fluctuating flow and vibration. These can be mitigated by operating pumps closer to their Best Efficiency Point (BEP), optimising impeller design or making system-level adjustments.

6. Pipe Strain or Improper Foundation

Even a well-built pump will vibrate if subjected to stressed piping or mounted on an unstable foundation. Relieving piping strain, installing adequate supports and ensuring pumps sit on rigid, level foundations provide long-term stability.

7. Electrical Issues in Motor

Motors can also be a source of vibration, particularly when affected by loose electrical connections, voltage imbalance or uneven power supply. Regular inspections, tightening of connections and monitoring of electrical quality are essential.

8. Preventive Maintenance & Monitoring

Preventive maintenance, a key aspect of APORM, is the most effective safeguard. Techniques such as vibration analysis, thermography and condition monitoring detect problems before they escalate. Establishing a structured maintenance schedule ensures pumps run reliably over time.

How Proper Pump MOC Selection Prevents Premature Failures in Chemical and Pharma Applications

by vemcoblogs -
Pump MOC Selection Prevents Premature Failures

In industries like chemicals and pharmaceuticals, pumps are constantly exposed to aggressive fluids. The wrong choice of Material of Construction (MOC) can lead to early failures, safety risks, and mounting costs. For plant engineers looking up “pump manufacturers near me”, understanding pump MOC is one of the most important steps in building a reliable and efficient system.

What Does MOC Mean in Pumps?

The Material of Construction refers to the metals, alloys, or linings used to build key pump components such as casings, impellers, and shafts. Since every process fluid behaves differently, choosing the right MOC ensures long service life and safe operation.

Common MOCs Used in Process Pumps

Leading brands like Kirloskar offer pumps in a variety of materials to handle diverse fluids. Some widely used MOCs include:

  • Cast Iron (CI): Cost-effective, ideal for non-corrosive water applications
  • Stainless Steel 316 (SS316): Excellent for mildly corrosive fluids, widely used in pharma
  • Duplex Steel: Superior resistance to pitting and stress corrosion
  • Hastelloy: Best for highly oxidising and reducing agents
  • Alloy-20: Designed for sulphuric acid and similar aggressive chemicals
  • PTFE-lined Components: Perfect for highly corrosive acids and solvents

As trusted Kirloskar pump dealers, VEMC ensures the right match between fluid properties and MOC.

Why the Wrong MOC is a Risk

Choosing incorrectly can cause:

  • Corrosion: Rapid thinning of pump walls, leading to leaks
  • Erosion: High-velocity abrasive fluids wearing out parts
  • Stress Cracking: Structural damage under combined chemical and mechanical stress
  • Pitting: Localised attack, often hidden until major failure occurs

A single oversight in MOC selection can compromise product purity in pharma plants or lead to downtime in chemical production.

How to Select the Right MOC

Engineers rely on chemical compatibility charts to evaluate MOCs against specific fluids. Factors like temperature, pressure, and concentration must also be considered. For example:

  • Sulphuric acid often requires Alloy-20
  • High-temperature caustic soda works better with Duplex Steel
  • Solvents in pharma may demand PTFE linings

Selecting the correct MOC at the design stage avoids costly retrofits later.

Long-Term Cost Benefits

While exotic materials may cost more upfront, they lower lifecycle costs by reducing downtime, repairs, and product losses. Proper MOC selection is not just a technical decision; it’s an investment in reliability and safety.
