Refrigerating Systems Based on Rotary Screw Compressors

TECHNICAL DATA

  • Cooling capacity: from 40 to 1,600 kW

COMPRESSIBLE GASES

APPLICATION

Rotary screw refrigerating compressor is similar to oil-injected compressor by its design. The mandatory part is a moving spool necessary for smooth regulation of cooling capacity from 100% to 10% depending on pressure and temperature of refrigerant.

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

DESIGN FEATURES AND ADVANTAGES

  • High-efficient profiles of rotors and spool capacity regulator provide increased specific energy values
  • Long run time between repairs
  • Minimal dimensions and weight
  • Absence of foundation

INSTALLATION

  • Compressor systems for permanent building of compressor station
  • Block-container version with all engineering systems

SCOPE OF SUPPLY

  • Compressor system (rotary screw compressor, electric  motor, base frame, coupling)
  • Evaporator-condensing unit
  • Lubrication system and automation
  • Piping and valves
