Our EG Series Compressors provide high-quality compressed air in the harshest environmental conditions. Incorporating the next-generation technology of ELGi's oil injected screw compressor provides long and trouble-free life at the lowest possible operating cost.

Lowest oil carryover in the industry

Because of our unique OSBIC process (Oil Separation by Impact and Centrifugal action) in EG Series electric air Compressor, it enables efficient separation of air and oil in 3 stages, delivering consistent oil-free air with minimum pressure drop.

Best-in-class warranty program

ELGi offers Uptime Assurance, which is all about giving customers peace of mind by providing the industry's leading warranty, which guarantees that its products and components will perform the purpose and function for which they are designed and intended for the periods indicated when used, serviced, and maintained in accordance with ELGi's instructions and specifications.

Outstanding dependability due to low operating temperatures and slower running speeds are built to operate in harsh temperatures ranging from cold to hot and dry to extremely humid conditions.

Operating data and safety measures

Our EG Series compressors are designed and perfected to ensure the highest level of safety for - pressure regulating valves, high pressure, high temperature, pressure relief valves, phase order and single phase.

Optional variable speed drives for energy efficiency

Our EG Series electric screw compressors feature perfect rotor clearances for best-in-class energy efficiency, which results in low operating speeds for long life, minimum maintenance, and low sound level. Our built-in Variable Frequency Drives (VFD) match compressor output with demand by altering motor speed. Hence, power consumption decreases with demand reduction, minimising the frequent load-unload cycle and wasting electricity from the energy bill.

Their durable performance ensures minimal downtime, allowing packaging companies to meet production targets, ensure product quality, and deliver reliable packaging solutions.

HOW DO ELGi EG SERIES LUBRICATED COMPRESSORS WORK?

ELGi's EG Series is based on the concept of lubricated compressors. The oil lubricated screw air compressor ensures smoother operations, reduced wear and tear, and a prolonged lifespan. The oil injected rotary screw compressor technology optimizes performance and minimizes energy consumption, making it an ideal choice for heavy-duty applications.

When the compressor's inlet filter draws in ambient air, the compression chamber becomes the core of the oil flooded screw compressor. This chamber consists of male and female rotors with helical lobes that interlock and gradually compress the air. A precisely controlled quantity of lubricating oil is injected into the chamber, during this compression. This oil serves multiple vital functions, including sealing gaps between the rotors, reducing friction, dissipating heat, and contributing to the system’s overall efficiency.

Following compression, the air-oil mixture is directed to an oil separator element, where centrifugal forces facilitate the separation of oil droplets from the compressed air. The separated oil returns to the compressor's oil circuit for reuse, maintaining an efficient closed-loop lubrication process. The purified and compressed air, now devoid of contaminants and excess oil, exits the compressor element and undergoes after cooling to reduce temperature and moisture content. The cooled and compressed air, stored in an air receiver tank, is then distributed to various applications, powering machinery, pneumatic tools, and numerous industrial processes.
