Eco Chiller

Energy recovery from cryogenic gases

02

The Eco Chiller is an automated solution for energy recovery during the vaporisation of cryogenic gases (e.g. liquid LN2, LAR, LOX, LCO2) designed to overcome the downsides of ambient air vaporisers.

Cryogenic gases are stored in vacuum-insulated storage vessel in liquid stage at very low temperatures (up to -196°C for nitrogen). When such gases are required in gaseous stage for subsequent processes, the liquid cryogenic gas has to be vaporised before usage. In order to vaporise such gases, heat energy is required. Either it is done with ambient air but the cold energy form the gas is lost, or with warm water which is cost extensive. The Eco Chiller tackles this issue. Instead of preparing warm water requiring extra energy input, the Eco Chiller uses the existing heat for vaporisation or with other words, recovers the energy from the cryogenic gas by cooling down the water flow.
