Discover the wide range of Hitachi's absorption chillers

Hitachi manufactures a range of absorption chillers with capacity ranging from 30 to 2000RT. Available types include:


  1. Steam Fired – include an integrated boiler to create the steam to drive the absorption chiller. Sub-types include Double Effect Steam type and Single Effect Steam.

  2. Direct Fired (Gas/Oil) directly generate heat for the absorption chiller from burning natural gas or oil

  3. Waste Heat Absorption Chillers & Heat Pumps can provide both cooling and heating solutions and are best suited where there is a steady source of waste heat, such as in industrial processes. There are 3 sub-types; Gene-link/Solar-link which use steam or natural gas and supplemental hot water from industrial and energy generation processes; Hot Water type which utilize hot water from solar heat or waste heat from generator, incinerator or production process; and Heat Amplifier type which uses low temperature waste heat to generate useful high temperature heat to go back into production processes.

Turning waste heat energy into cooling and heating solutions

Hitachi absorption chillers, powered by natural gas or other thermal energy sources, utilize water as a natural refrigerant making them exceptionally sustainable. Recently, advanced absorption chillers have been developed to effectively utilize waste heat from co-generation and solar sources, while modern absorption heat pumps can provide simultaneous cooling and heating capabilities.
