Hitachi launches modular water cooled chiller range

Hitachi Air Conditioning Europe launches new modular high seasonal efficiency water cooled chillers

The Samurai RCME-WH Series consists of four basic modules: 140kW, 180kW, 220kW and 260kW.

Combining these modules up to a maximum of 8, it is possible to achieve a chiller combination of up to 2,080kW.

With the world-renowned Hitachi screw compressor optimised for R134A and part load performance, the units achieve seasonal efficiencies up to 6.80.

Utilising true dual type plate heat exchangers, twin electronic expansion valves, and cyclonic oil separator means the units also have a very low refrigerant charge, up to 60 per cent less than similar capacity chillers.

According to Hitachi, site flexibility has also been enhanced with two Operating modes (Standard and High Efficiency), internal power demand limitation and two pump operating modes all configurable from the colour LCD control panel.

Furthermore, with continuous capacity control from 3% ~ 100% (dependant on module combinations), water outlet temperatures can be controlled to +/-0.5°C.

“With the forthcoming European ErP legislation plus the new European F-GAS Regulation, our new Samurai RCME-WH Series units are in the best position to meet these requirements, with their market leading seasonal efficiencies and low refrigerant charge,” commented Glyn Jones, European Product Manager.
