Efficient Energy

Efficient Energy sets new standards for chillers that are used in data centers, industrial and other applications. The main differentiator is the use of water as a refrigerant. Water is the fluid with the highest enthalpy of evaporation of all fluids but needs a high volumetric flow rate in the useful temperature range of 10 to 20°C.

Efficient Energy has developed an innovative turbo compressor and process circuit. Efficient Energy's range of eChillers feature a fully integrated free cooling process and achieve a 30% to 50% reduction of energy consumption compared to conventional HFC or HC based refrigeration circuits. Its refrigerant water R718 is clean, it does not deplete ozone, nor does it warm the planet, it is not toxic nor flammable. There is no need to conform to any regulations, not the f-gas regulation, not the pressure equipment directive nor the EN 378.

Efficient Energy has been awarded the European Business Award for Environment, the RAC Cooling Industry Award 2017, the Partslife Umweltpreis 2017, the Deutschen Rechenzentrumspreis 2017 and the Deutscher Kältepreis 2016.
