The W-series chillers are robust, dependable workhorses that provide a reliable supply of process coolant at constant temperature and pressure. Combining a a high efficiency, corrosion resistant plate heat exchanger, compressor and a non-ferrous pump, the W-series is suitable for both glycol and deionised water. By using R 134a refrigerant, fridge pressure is minimised and therefore allows operation in ambient temperatures as high as 55 ºC. All Chillers in theW-series range incorporate an antifreeze thermostat to protect the plate heat exchanger and integrated pres­sure switches to protect the fridge circuit against high and low pressure. Housings are made from galvanized steel and externally coated to provide corrosion protection against the harshest of environments.
