3.2 Intended use
3.3 Chiller design
This chiller unit is used for the chilled water production and for the chilled water temperature control. The chill-
er is designed for outdoor installation. Any use beyond this is not deemed to be use as intended. STULZ is not
liable for any damage resulting from such misuse. The operator alone bears the risk.
The chillers of the CyberCool2 series with screw compressors exist in 7 construction sizes, which differ by
their length and cooling capacity. An overview of the construction sizes can be seen on pages 49/50.
The side, on which the electric cabinet is located, is named front side in these operating instructions.
The compressors are installed one upon the other in a separate cabinet, which can be accessed by removing
four panels. Each panel is fixed by eight allen screws.
Behind the panels on the right side there is a set of pressure switches and pressure gauges for each refriger-
ant circuit, as shown below.
