Delivering Air Conditioning Excellence

Chillers

Samurai Chillers offer world-renowned reliability thanks to Hitachi’s own twin screw compressors.

Samurai are commercial and industrial chilled water systems, including cooling only and heat pump air-to-water, water-to-water and condenserless types.

The Samurai are based upon Hitachi’s peerless twin screw compressors, which are industry renowned for their efficiency and reliability. A slide valve provides continuous capacity control from 15 – 100% at high part load efficiency, while maintaining impeccable low vibration, low noise levels and a high power factor.

Samurai chillers include many high specification features as standard, such as acrylic coated condenser coils and star delta compressor motors.

Accurate +/-0.5??C water leaving temperature control is possible, with water leaving temperature controlled from -10??C to 15??C on cooling capacities from 106 kW to 1280 kW.

Air Cooled Cooling Only

RCU2E-AG2 Air Cooled Cooling only – capacities from 40HP to 400HP (112kW to 1030kW)

  • Continuous capacity control provides 15% to 20% energy saving compared to step control
  • Low noise

High technology DC Inverter fans achieve a reduction of sound emissions, increasing air volume and reducing power consumption. Low noise and super low noise models are available

  • Precise temperature control of outlet water to within +/-0.5°C, independent of cooling load
  • Excellent partial load performance
  • STAR DELTA starting system reduces the maximum starting current
  • Twin screw compressors – highly reliable with very low noise and vibration
  • Small installation space

Thanks to meticulous design of each component, it is possible to achieve exceptionally high cooling capacity values per square metre

  • Optional recovery system

Recover 30% of the output power in cooling mode by heating the water in a dedicated circuit with outlet temperatures up to 70°C at maximum working conditions.

Due to the meticulous design of each and every component, it is possible to achieve exceptionally high cooling capacity values per square meter installed
