In the new model sereis, the power consumption is largely reduced over the current model series due to newly designed high-efficiency cooling system. Also COP is largely increased from 4.42 in the current 100HP model to 5.13 in the new 100HP model.

Technical Features

High-performance A-type Screw Compressor ~Newly Designed~

Suctioned Refrigerant Gas

Discharged Gas Cyclone Oil Separator

Oil

Differential Pressure Lubrication Mechanism

Oil Reservoir

Screw Rotor

Built-in Cyclone Oil SeparatorLow oil carrying-out is realized and reduction of heat transfer efficiency is minimized.

No outside pump is required due to the reliable differential-pressure oil-feeding system. This oil-feeding system, which does not use any electrical mechanism, prevents the compressor from being damaged and maintains long-term stable operation.

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

Low Vibration, Low NoiseWithout the conventional demister chamber system, no noise is produced during oil separation of discharge gas. A vibration-proof base is not required for the chiller body thanks to the firmly-secured, low-vibration screw compressor.
