System Free Indoor Units

System Free Indoor Units

Samurai are 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 & noise level and a high power factor.
