Centrifugal Chillers

Hitachi Centrifugal Chillers uses HFC134a, refrigerant with an ozone depletion potential of zero. The High-pressure HFC134a refrigerant enables downsizing and weight reduction of the rotating body components in comparison to other refrigerant types. Consequently, the energy loss caused by rotation is reduced for consistent downsizing and high efficiency is achieved. Hitachi’s unique capacity control mechanism allows energy-saving operation throughout the year with its stable capacity control.
