1 Cooling capacity can be changed via electronic controller. Nominal cooling capacity is stated for airtemperature of 35 °C in hot zone, without condensation (relative humidity under dew point). Watertemperature is 10/15 °C, clean filters.

2 Net cooling capacity (without heat from fans) is usable cooling capacity of entire system

3 Airflow is changed by control needs. Nominal airflow equals nominal cooling capacity.

4 Without any base frame

5 Bottom side length 400 mm; top side length 600 mm

6 For weight with droplet separator, add 11 kg
