eChiller – the carbon neutral cooling machine with the safe and natural refrigerant water
eChiller is the only chiller available in standard that uses pure water (R718) as a refrigerant.
The principle is not new: Our technology builds on the direct evaporation, compression, condensation and expansion of water or water vapor in a closed-loop cycle. Depending on the application, this process takes place in a vacuum at low pressures between 10 to 100 mbar and in the temperature range of 5 to 45 °C.
The production of the eChiller has been climate-neutral since 2022.

Environmentally friendly and efficient industrial cooling with Bluezero from Efficient Energy
Sustainable industrial cooling really works: Our eChiller works with the direct evaporation of water in a vacuum-tight system and closed circuit, which is hydraulically decoupled from the re-cooler and the cooling point via plate heat exchangers.
Bluezero technology stands for a unique sustainable innovation in refrigeration industry because it makes water as a refrigerant possible and transforms the increasingly regulated and environmentally harmful refrigeration and air conditioning technology into a CO2-neutral life cycle assessment. The centre-piece is the knowledge of Efficient Energy, in which the energy of water can be used during the phase change in a vacuum between 10°C and 120°C.
Bluezero has been successfully used in the eChiller for several years and is also used as integrated OEM solution. With Bluezero you can take advantage of all benefits that water as a refrigerant provide – by integrating the technology in your own branded product.
