Product Description

Screw Air Compressors

The EG Series compressors represent a giant leap in design and performance with each component designed for reliability and ease of maintenance.The compressor is manufactured in compliance with applicable international standards (UL, ASME, CE and others) and designed as per the international quality standards These new generation compressors significantly reduce operating costs and provide cost savings with fast return on investment.

High volumetric efficiency

  • Low energy cost per cfm
  • Advanced Neuron II Controller (Remote management of compressor operations)
  • Ready for SCADA/DCS
  • Highly efficient super breed Eff1 Motor
  • Energy cost savings
  • Option of in-built Dryer and VFD
  • Compact and saves floor area.

Save Energy

Highly Efficient Airend

Elgi's airends are equipped with in-house developed eta-V profile rotors, With 4/5 lobe combination, the rotors are designed to run at optimum speeds. This unique design reduces pressure losses and increased efficiencies. The rotors ensure energy-efficient compressed air supply for all demanding applications.

  • Precise rotor clearances for best in class energy efficiency.
  • Low operating speeds for long life, low maintenance and low sound level
  • Complied with applicable safety standards

Reduced Starting Load

Intake Valve System

The new generation intake valve with integrated blow down unit, solenoid controls and actuators is designed for low losses. Intake valve optimally controls the compressor capacity during startup reducing the no-load power. This Optimal Capacity Control results in direct savings on power consumption.

Oil-Less Air (lppm)

Efficient air-oil separation with OSBIC(3 Stages)

Elgi has applied unique OSBIC process (Oil Separation By Impact and Centrifugal action) which 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

Moisture-Free Air

99% Water Free

Depending on the humidity level of inlet air, bulkwater remains in compressed air at varying levels and causes corrosion of piping, end tools, machinery and valves. Global Series air compressor has a custom-designed centrifugal type moisture separator with an automatic timer controlled drain. This comes as a part of the package at no extra cost and removes over 99% of bulk water from the compressed air, resulting in corrosion free, longer life of en d use equipments and less load on the dryer.

Cool Air

Efficient air cooling

The cooling system with fans and larger cooling surface area enhances the cooling of hot air.The fan motor uses significantly low power. The integrated fan-motor assembly maintains low temperature there by increasing the life of motor.

Smart cooling system design enables easy maintenance and ducting. More over, the complete system is insulated internally from other zones.

Robust and Reliable

Reliability under extreme conditions

EG series compressors are designed to perform at extreme temperatures – from cold to hot and from dry to extremely humid conditions

Performance Control System

  • Built-in Dryer Dew Point integration
  • VFD Parameter (Power, HMR, Frequency, Ampere, Voltage)
  • Read out and closed loop control
  • Selectable AO (Pressure/Temperature/Dew Point) for DCS integration
  • Controlled drain system

Reports

  • Cumulative Report (Run Hours, Load Hours, Unload Hours, Stop Hours, Fault Hours and remaining AFCT, OFCT, OSCT, OCT and RGT)
  • Detail Report - Previous 15 Days (Load Hours, Unload Hours, Stop Hours, Fault Hours, and Number of times machine stopped due to standby)
  • Fault Report - (Previous 99 Faults in chronological order with Real Time stamping and type of fault)

Remote Monitoring

  • DCS (MODBUS RTUIRS 485): Controller is enabled to synchronize with Distributed Control System - control of compressor from control panel of customer
  • SCADA : Compressor control through PC with remote monitoring by Supervisory Control And Data Acquisition process

Energy Saving -The CONSERVE Way

In-Built ELGI Conserv® Variable Frequency Drives (VFD)

Matches compressor output with demand by varying motor speed. The power consumption reduces in line with the reduction in demand. Helps in eliminating the frequent load-unload cycle and also the wasted power from the energy bill.

A fixed speed compressor operates on a load unload band of at least 10 psi around the working pressure whereas with Elgi VFD, compressor can be operated within a band of 2 psi. Since the compressor is not operated under higher than working pressure requirements, there is substantial energy saving. For every 2 psi reduction in operating pressure, there is 1% power saving.

In a fixed speed compressor with Star-Delta starter, starting current is as high as three times the full load current (FLC). With Elgi VFD starting, starting current is less than the FLC. This helps to avoid using heavy rated components like fuses, MCCB, cable size, generator rating, isolators etc.

For compressed air systems with fluctuating demand pattern, giving a fast return on investment
