  • Discharge pressure: 2 MPa (20.4 kgf/cm2)
  • Drive power: 1 600 kW

COMPRESSIBLE GASES

APPLICATION

Compressor system
96GV-200/19C

The rotary screw oil-free compressors are intended for compression of gases when technology process requires no any oil vapors. This type of compressor contains driving and driven rotors, placed in a casing that may have water cooling jacket. The rotors rotate in a support and trust slide bearings and have connection gear wheels that fix the rotors with necessary spacing between them eliminating their mutual contact.

The basic models can be modified in accordance with the customer requirements.

DESIGN FEATURES AND ADVANTAGES

  • Resistance to ingress a liquid phase into compression space
  • Operation in a wide range of capacity and composition of compressible gas
  • Application of high-efficient gas coolers to decrease temperature of compressed gas
  • High energy efficiency of the compressor system due to variable frequency drives
  • Minimal leaks and losses thanks to optimized compression process

 

INSTALLATION

  • Compressor systems for permanent building of compressor station
  • Block-container version with all engineering systems
  • Hangar version for installation in an easily-constructed prefabricated building including engineering systems.
  • Compressor systems for outdoor installation
