Global Series Screw Air Compressors Life source of industries - 200 HP
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 EG Series 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. RELIABILITY EFFICIENCY PERFORMANCE TECHNOLOGY NOISE LEVEL DOWN TIME MAINTENANCE OIL CARRY OVER Efficient Design 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
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 -60% in loading and in load-unload mode for loads below 60% Constant pressure due to gradual opening or closing of suction valve with Controls 120 Energy savings over load/no-load control only Input Power % 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 80 60 40 20 0 10 20 30 40 50 60 Load % Modulation 70 80 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 motors are built according to NEMA specifications with Class F insulation and IP55 protection Designed for severe duty atmospheric conditions Premium efficiency motors with their efficiency values certified by UL 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
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 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 Cooling The compressor is designed to operate in wide temperature range from 320F to 1F 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 User-friendly and intuitive display has back light for easy reading Remote monitoring capability through RS485 connection Easy to install, configure, fine tune and also to remove if necessary In compliance with CE, UL, cul and GOST R Optimal pressure sensors monitor compressor internal pressure differences to optimize compressor maintenance Navigation is done through ergonomically arranged key switch panels Supports multiple languages Better network responsiveness when compared to conventional network protocols such as MODBUS Designed for the most arduous condition How loud is too loud? 40 60 Rain drops Normal Conversation 85 Traffic Hair Dryer 105 Concerts Chainsaws 120 ipod Jackhammer Gunshot with peak volume Global Series - High Performance
