Water-Cooled Screw Chillers

Thanks to infinite capacity control, 15~20% energy saving is possible compared with current step control systems.

Thanks to this modulation, the compressor load is always matching with the requested load, and thus accurate chilled water temperature is achieved without expensive inverter devices.

Samurai Water-cooled Screw Chiller

Available in:

Cooling only, heat pump

Nominal Capacity Range (cooling): kW

140,180, 220, 250

Refrigerant:

R134A

Precise temperature control

Combinations of “Continuous Capacity Control Compressor” and “Hitachi’s unique electronic controls” enable the Chiller to control outlet water temperature precisely, independent of cooling load.

This control benefits not only air conditioning, but also industrial process use.


BMS CONNECTIVITY

Additional modules allow for BMS connectivity over comms.


FLEXIBLE INSTALLATION

Able to simply adapt to various applications


PERFECT FOR REPLACEMENT

Modular design is an ideal solution for quick compact and space adaptable installations


SCREW CHILLER

Samurai air-cooled reliable screw chiller

Screw compressor

The Hitachi Samurai range incorporates a new twin screw compressor optimised for R134a refrigerant and the latest development of Hitachi’s screw compressor technology with the Hitachi’s Infinity Capacity Control from 25% to 100%.

With this modulation, the compressor load is always matching with the requested load, and thus accurate chilled water temperature is achieved without expensive inverter devices.

Infinite capacity control

Hitachi’s Infinite Capacity Control system uses advanced electronic controls to position the infinitely variable slide valve within each compressor.

This modulation allows exact load control and accurate chilled water temperature without the need for expensive inverters.

Precise temperature control

Combinations of “Infinite capacity control compressor” and “Hitachi’s unique electronic controls” enable the Chiller to control outlet water temperature precisely, independent of cooling load.

This control benefits not only air-conditioning, but also industrial process use.
