The cooling units are available with different cooling capacities. See the chapter "Refrigeration circuit"for exact performance
data.
The cooling units have a cut-out compatibility with air/air heat exchangers and air/water heat exchangers. The use of aluminum
filters, felt filters or bellows filters is possible with an additional adapter.
The cooling units of the X-series are equipped with the Premium Controller. The control unit can be used to set the operating
parameters. These controllers are control unit for setting refrigeration functions and operating data. They also enable readout of
