The I-Series screw compressor has a capacity of 55.5 to 116.9 tons of refrigeration. It can operate with anhydrous ammonia or R-22. It is available in 160-mm rotor diameter and 180-mm rotor length. The iP control panel is made for this compressor using the company's Yosaku liquid injection system.

The compressor package can be designed for the optional variable-frequency drive system. No oil pump is required; oil pressure is generated by suction/discharge pressure differential.
