Technical Features

H igh-performance A-type Screw Compressor ~Newly Designed~ Built-in Cyclone Oil Separator

NEW

Low oil carrying-out is realized and reduction of heat transfer efficiency is minimized.

High Technology by Internal Manufacture Because all manufacturing processes, from rotor manufacturing to unit assembly, are done internally, exceptional reliability is achieved.

New Screw Compressor Operation Image

No outside pump is required due to the reliable differential-pressure oil-feeding system.

Discharged Gas

Cyclone Oil Separator

Suctioned Refrigerant Gas Screw Rotor

This oil-feeding system, which does not use any electrical mechanism, prevents the compressor from being damaged and maintains long-term stable operation.

Oil Oil Reservoir Differential Pressure Lubrication Mechanism

Simple Structure with a Small Number of Parts Whereas the number of main parts for the casing, compression mechanism and capacity control mechanism of a reciprocating compressor is 268, that of a screw compressor is only 27, just one tenth of the number ! A structure with so few parts offers high reliability and easy maintenance.

Vibration Comparison

Low Vibration Level No exclusive vibration control equipment is necessary by using low-vibration screw compressor.
