SIGA CSHEHWH-1270
Description
Description:
The range includes models that cover a refrigeration capacity ranging from 1 to 1500 kW. Compact chillers are for outdoor installation. The range has been designed for use both in the process and comfort sectors. The machines are equipped with all the components that ensure automatic cooling of water or a water/glycol solution. To guarantee maximum operating safety the units have (or can have) two completely independent refrigeration circuits. All units are supplied with a full oil and refrigerant load after having been factory tested. The chillers are divided in two product ranges: chillers with scroll compressors and chillers with screw compressors. For scrolls refrigerants used are R407C/R410A/R404A, while for screw compressors refrigerants are R407C/R134a/R404A. Models where scroll compressors are used are installed with shell and tube evaporators or plates evaporators (or coaxials). Models with screw compressors are installed with shell and tube evaporators, with optional opportunity of high efficiency evaporators for R134a refrigerant, which reach energetic Class A.
