Screw Compressors

More robust, reliable, efficient and maintenance-free than scroll compressors.

Ecological gas

The RHD range of chillers benefit from a wider variety of available gasses, allowing Frigosystem to combine efficiency and payback.

Shell & tube evaporator

Robust technology allows for higher flow rates.

Free cooling

For energy savings, RHD can be combined with a seperate dry cooler or integrated free cooling.


RHD chillers have many options that can be included. Many customers choose the automatic free cooling feature, which (during favourable cooler ambient conditions) will bypass the energy intensive compressors of the chiller and provide significant utility savings.
