TECHNICAL DATA

Cooling capacity: from 40 to 1,600 kW

COMPRESSIBLE GASES

APPLICATION

Oil Refining & Petroleum Chemistry

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
