The most natural refrigerant in the world – 100 percent water (R718)

eChiller: Sustainable Refrigeration Technology

eChiller Technology from Efficient Energy

eChiller is the only chiller available in that uses pure water (R718) as a refrigerant.

The principle is not new.  The 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 45oC.

eChillers can be used within industries where there is a constant and high demand for machine cooling, space cooling, cooling required for industry processes.  The eChiller effectively replaces traditional air conditioning systems which are based on refrigerants like R410A and R134A, etc – which are refrigerants with high global warming potential and will soon be phased out.

Environmentally friendly and efficient industrial cooling with BlueZero from Efficient Energy

The eChiller works with the direct evaporation of water in a vacuum-tight system and closed circuit, which is hydraulically decoupled from the recooler and the cooling point via plate heat exchangers.

Efficient Energy’s BlueZero technology 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 centrepiece is the know-how of Efficient Energy, in which the energy of water can be used during the phase changed in a vacuum between 10oC and 120oC.  The core applications of the BlueZero technology are cooling and heat pump solutions.  BlueZero has been successfully used in the eChiller for several years  With BlueZero you can take advantage of all benefit that water as a refrigerant provide – by integrating the technology in your own branded product. 

BlueZero – because water is blue and has zero emissions.

The eChiller is ideally suited for the cooling of machines and production, industrial processes and technical building equipment.
