Water cooled efficiency

 
 

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 chiller



 


Available in:

Cooling only, heat pump

Nominal Capacity Range kW (cooling):

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.

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.

Intuitive display

 

Each Hitachi module of the RCME-AH2 and RHME-AH2 series is equipped with a user-friendly touch screen providing:

Unit Parameters:
