absorption units are mainly used for refrigeration or cooling applications. Unlike compressor type cooling units, they do not need electricity for operation but run on thermal energy such as a gas flame.

Units with auxilary inert gas are called diffusions-absorption units. They operate totally independed from electricity. They are maintenance-free, noiseless and have a very long lifetime due to lack of mechanical wear.

ENTEX utilized diffusion-absorption units only from 20 Watt cooling performance 2up to approc 10 kW heating performance.
