EG SeriesScrew Air Compressors Life source of industries

90-160 kW

Global Series

Screw compression elements are manufactured in-house using state-of-the-art machining centres for rotor grinding and machining castings of various sizes. Elgi’s exclusive Axis airends ensure energy-efficient compressed air supply for all demanding applications.

Axis airend is powered by Elgi’s efficient profile rotors Axis airend is internally lubricated to eliminate oil leakage Axis airend with 4x5 ground rotor combination lobes results in optimum efficiency at 100 -115 psi g (7- 8 bar g) and reduced compression

losses provide better specific power consumption per kW Axis airend has high volumetric efficiency and high isentropic efficiency

The new Global Series electric powered screw compressors stands as proof of Elgi’s spirit of continuous development. Combining reliability with energy-efficiency, Elgi’s new Global Series compressor system is designed with improved features like space-saving, significant reduction in noise level, efficient moisture separator, low oil-carry over and user-friendly controller. Moreover, low power and reduced maintenance needs ensure that operating costs will remain low throughout the compressor life. The compressor is manufactured in compliance with applicable international standards (UL, ASME, CE and others) and designed as per the international quality standards.

Efficient Design

Global Series - The Technology Edge

Optimal Flow Control The new generation intake valve with integrated blow down unit, solenoid

switch and actuator is designed for low losses

The intake valve is optimized for dual mode operations

Large size of the intake valve minimizes pressure drop and suction losses

Modulation unit ensures effective control of inlet air flow and maximizes power savings

Auto dual control operates on modulation mode from 100-60% in loading and in load-unload mode for loads below 60%

Constant pressure due to gradual opening or closing of suction valve with respect to demand (multi-point) control

Option for selecting load-unload/modulation auto dual mode for all large screw compressor models as a standard feature

Smooth operation by modulation ensures longer life of airend, valves and all mechanical components. It also ensures no sudden spikes or drop in line pressure

Lowest power consumption in its class of compressor controls, even with fluctuating loads

MAXIMUM Energy Efficiency

High Efficiency Drive System Heavy duty TEFC squirrel cage induction motor with class F insulation and IP55

protection for assured operation in dusty environment Wide operating voltage +/- 10%

0 Motor selected for high ambient of 45 C with power variants 415V/400V/380V in 50 Hz Motor winding temperature limited to Class B temperature rise Optimized ventilation system for cooler operations and reduced noise levels Solid base for reduced vibration levels Regreasable ball bearings Gasket for conduit box

Drive Coupling Ensures efficient power transmission with uniform load on bearing due to permanent

alignment of airend and motor Easy serviceability and replacement of the coupling element without dismantling the

drive system

Efficient Air Filter System Use of pre-filters ensure clean air suction unit and enhances air filter life cycle

Heavy duty dry type air filter ensure two ways of filtration by centrifugal action and by paper filter cartridge with 99.9% efficiency

Optimally sized high efficiency filter provides maximum filter life and clean intake air

Air filter with visual condition indicator and silencer for easy maintenance of the system

Automatic cleaning of air filter for every cycle of upload operations

MAXIMUM Reliability

Global Series - Highly Reliable

Energy savings over load/no-load control only

Performance Control System An advanced and intelligent Elgi control system matches the Global Series compressor needs by

providing precise and complete monitoring and controls

Intelligent controller enables remote monitoring, synchronizing with Distributed Control System and SCADA

Efficient Air-Oil SeparationOSBIC designThe efficient air-oil separation by OSBIC (Oil Separation By Impact and Centrifugal action) enables efficient separation of air and oil, with minimum pressure drop. The method enables separation of oil in three stages, delivering consistent oil-free air while increasing the life of separator element

Stage 1: Impact of air-oil mixture on the radial baffle plate reduces kinetic energyStage 2: Centrifugal action of air-oil mixture (spin down action) to shed of the oil particlesStage 3: Air with minor traces of oil will enter the air-oil separator element placed inside the tank to purify

the air (residual oil carry over level is 1ppm)

Smaller oil volume with industry lowest refill requirements

ASME design and CE/GB certified

Minimum pressure drop in tank

Leak proof flanges with O-rings ensure leak free connections

Integrated Moisture Separator as Standard Designed to handle high humid compressed air outlet from after-cooler

99% of bulk water removal by Impact and Centrifugal action with minimum pressure drop and automatic discharge of collected water particles by float mechanism

Efficient Air Cooling0 0 The compressor is designed to operate in wide temperature range from 0 C to 45 C

with a very low after cooler approach temperature

Sucker type, quiet and high capacity cooling fans reduce the input power while ensuring efficient cooling air flow

Unique cooling air path for aftercooler by means of closed air duct which separates cooling system from rest of the unit

Easy access to cooler cleaning ensures fast maintenance and improves reliability
