Efficient Energy, the German manufacturer introduces a new chiller with a 120kW (34.1TR) cooling capacity suitable for industrial cooling and using only water (R718) as refrigerant.

The eChiller120 model is suitable for process and machine cooling applications like laser heads, rollers and cooling basins; it can also be used for technical air conditioning of data centers and server rooms. The eChiller is equipped to produce chilled-water temperatures between 16°C (61°F) and 22°C (72°F).

Georg Dietrich, Efficient Energy GmbH’s CEO and MD said, “Our eChiller is the only series product worldwide that works with water as a refrigerant and therefore does not generate any direct CO2 emissions.” The eChiller120 will complement Efficient Energy’s current range, which includes 35kW and 45kW (10 to 12.8TR) R718 chillers. Those units can be combined and scaled up to 300kW (85TR).

The eChillers are suitable as standalone systems. They can also be connected to existing coolers, and for example do subcooling for transcritical CO2 systems. Efficient Energy, based in Feldkirchen,  is ready to take orders for the new eChiller120, and expects to begin delivery in the summer of 2021. The new eChiller120 is up to 82% more energy efficient than conventional chiller systems, Efficient Energy said in a press release announcing the launch.

The company said, in the last six years, the company has implemented around 25 data center projects with eChillers in major data centers like British Telecom, a London-based telecommunications and broadband provider.
