Energy Saver:
Elgi Tandem compressor is a two-stage compressor, having high energy-efficiency . the compression is done in two-stages to improve the volumetric efficiency and thereby contributing to decrease in power consumption and increase in saving energy costs. Tandem air compressors consume 8-12% less power and offer a return on investment within 8-15 months when compared to single-stage compressors

For the same discharge pressure of 9 bar, a single-stage compressor has compression ratio of 1: 9 ( Ratio of suction to discharge of a screw airend) . the compression ratio is divided between the two stages of tandem airend and is about 1: 3 in each stages of two-stage tandem compressors. This makes the airend more reliable and efficient due to smaller loads on bearings. The volumetric efficiency of two-stage is better than single-stage compression

Dual Control mode:
* Auto dual control, operates on modulation mode from 100-60% 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 standard feature
* Smooth operation by modulation , ensures longer life of the airend, valves and all mechanical components. Also, ensures no sudden spikes or drop in line pressure
* Lowest power consumption in its class of compressor controls, even with fluctuating loads
