1 EG Series Screw Air Compressors Life source of industries kw

2 EG Series ELGi, established in 1960, designs and manufactures a wide range of compressors. The company has gained its reputation for design and manufacture of screw compressors through strategic partnerships and continuous research and development. Over the years it emerged as a multi-product, multi-market enterprise providing total compressed air in all segments. ELGi s design capabilities translated into a wide range of products ranging from oil-lubricated and oil-free rotary screw compressors, reciprocating compressors and centrifugal compressors. ELGi has its own manufacturing operations in China, France, India and Italy with subsidiaries in Australia, Brazil, Indonesia, UAE and USA. The company is fast expanding its global footprint attracting distributors and customers with its latest generation The new EG Series electric powered screw compressors stands as proof of ELGi s spirit of continuous development. Combining reliability with energyefficiency, ELGi s new EG 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 RELIABILITY EFFICIENCY PERFORMANCE TECHNOLOGY NOISE LEVEL DOWN TIME MAINTENANCE OIL CARRY OVER 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 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 Global Series - The Technology Edge

3 MAXIMUM Energy Efficiency 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 % 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 Input Power % Controls Energy savings over load/no-load control only Load % Modulation Load-noload MAXIMUM Reliability 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 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/80V 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 Global Series - Highly Reliable

4 MAXIMUM Performance Efficient Air-Oil Separation OSBIC design The 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 energy Stage 2: Centrifugal action of air-oil mixture (spin down action) to shed of the oil particles Stage : 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 Cooling 0 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 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 The controller enables report generation viz. cumulative report, detailed report for the previous 15 days and fault report (Previous 99 faults in chronological order with real time stamping and type of fault) How loud is too loud?
