SCREWLine3, the new generation of R134a chillers with double screw compressors, from 520 to 1550kW are now available in FREE-COOLING (both direct and indirect) version for applications which require cooled water during the cold season, such as industrial processes, data centres, telecommunications, technological applications and shopping centres.
When the outdoor ambient temperature is lower than the return water temperature of the system, the FREE-COOLING system utilises this variance and reduces compressor operation accordingly. In this way the requested cooling capacity is supplied at reducing cost relative to the temperature variance.
Even when the performance of a chiller at low ambient temperature is cri...
