General functional description
Welcome to the ELGi customer family. ELGi compressors
are the source of compressed air in various segments
across the globe.
ELGi compressors are known for:
 Greatest reliability
 Fewer maintenance intervals
 Ease of use
 Highest safety
The ELGi screw compressor is designed to deliver:
 High energy efficiency
 Low maintenance cost
 High discharge air quality
All the above factors assure a low life-cycle cost.
The rotors incorporate a specially designed eta-v profile-
ELGi patented profile-which emphasizes on improving
reliability, performance, and efficiency. The Eta-v profile is
the latest and the most energy efficient profile in the
industry globally, assuring consistent performance during
the entire life of the compressor. ELGi screw air
compressors incorporate a compact design and
compressor run with low noise or vibrations. The capacity
control system ensures optimum air intake during start-
up, normal running, and unloading stages, minimizing
power consumption. The oil separation system ensures
that maximum oil is separated from compressed air,
ensuring the best air quality with very little oil carry-over.
Uptime
At ELGi, we are changing the way you look at compressed
air systems. It’s no longer just about delivering air. It’s
about delivering uptime. Our uptime design ensures that
the compressors run cooler, cleaner, and longer with
longer service intervals. The uptime components deliver
the best in quality and enable your compressor to run
smoothly, efficiently, and profitably. With uptime
assurance, we back our pledge, with industry-leading
warranties, parts availability, loaner compressors, and call
centres staffed by experts. We thank you for purchasing
an ELGi compressor and assure you the best service
during the entire life of the compressor.
EN SERIES
Your EN SERIES compressor belongs to a family of rotary
screw compressors from ELGI. The compressor has only
two moving parts - the rotors - which are separated by a
thin film of oil to prevent wear and increase compressor
reliability.
The screw compressor technology ensures that output
capacity does not diminish even after many years of
operation. It involves a continuous flow of air through
helical cavities in the screw so that compressed air
delivery is pulsation free.
EN SERIES compressors ship in a compact design and are
self-contained. The absence of reciprocating parts helps
the compressor run without noise or vibration. The
discharge temperature of the coolant oil is low, less than
195°F (90°C) under normal conditions, and therefore,
carbonized oil does not form in the compressor.
