The KW25 is a chiller based on the principle of water evaporation. In combination with Erich Keller air conditioning units, the KW25 can be used as the sole chiller for over 90% of the year. This makes it possible to dispense with the use of refrigeration machines using compression refrigeration wherever possible. This consistent use of free cooling ensures highly efficient operation.
With this form of cooling, outside air flows through the system and passes through the integrated heat exchanger. If necessary, water is sprayed onto the pipes. This produces evaporative cooling; the KW25 then works as an evaporative cooler. The nominal capacity of the chiller is 50 kW with a coefficient of performance of at least 25. The device can be installed outdoors as well as indoors.
