Electric-Lubricated-Screw-Compressors2

Elgi’s EN Series screw compressors are designed to encapsulate all functional components of the compressor within a common housing. With a small footprint, high reliability and low maintenance requirements, these compressors are ideal for industrial applications where size, efficiency and cost matter.

Applications

  • Paper & pulp
  • Machine tool shops
  • Textiles
  • Cement
  • Automotive
  • Steel making
  • Food processing

 


  • Oil carry over less than 2ppm
  • Grouped service points ensure easy access to components for maintenance
  • Optimized cooler design and cooling fans ensure low running temperatures
  • Versatile neuron II micro controller provides easy diagnostics of system parameters
  • Models available as bare units/side located drier/variable speed drive variants
  • Wide range of accessories – vertical air receivers, driers, automated supply side controller and variable frequency drives to meet diverse operating conditions

 

Ratio of Suction to Discharge of a Screw Airend:

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

Energy Efficiency of Tandem Screw Compressors:

Elgi offers tandem screw compressors to help industries reduce their operating and energy costs. It is two-stage compressor, having energy efficiency as the key features. 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.
