Water as a Refrigerant
The right choice of refrigerants is an ongoing issue in the industry, especially after the European F-Gas Regulation took effect on 1 January 2015, further restricting the use of HFCs (hydrofluorocarbons). The eChiller uses water as a refrigerant, therefore making it the optimal solution – environmentally and economically.
Water as a refrigerant is the unrivalled alternative. None of the environmental and safety regulations relating to the current and future operation and maintenance of refrigeration units apply to water (R718). That lowers the equipment, operating and maintenance costs, secures your investment, and has a positive effect on the future of our global climate.
After a lifetime of use in the eChiller, the water contained in its closed-loop system can be released back into the environment.
There is simply no better solution – economically or environmentally – to your cooling applications.
Water as a refrigerant – past and present
Since the end of the 17th century, water has been used industrially on a significant scale as a refrigerant in absorption systems, initially together with sulphuric acid and later with lithium bromide. Water is also frequently used in adsorption processes, especially because of its outstanding evaporation enthalpy and environmental friendliness.
The use of water for stream blasting refrigeration, by contrast, is a niche application. Until now, water as a refrigerant in compression chillers has not been economically viable. Despite numerous attempts, series production readiness remained beyond reach.
But Efficient Energy achieved this quantum leap. Thanks to a revolutionary approach and many years’ development work, the eChiller is now available as a series product!
