All compressors are selected for their availability, reliability and low running costs and the choice ranges from fully to semi-hermetic type, depending on application. Models 2-11 are fitted with pressure relief devices to maintain constant set pressures to suit requirements. This valve also protects the pump in the event of a downstream valve closure. All fluid circuit are in non-ferrous materials.
Standard units have air cooled condensers constructed from copper coils with aluminium fins.
Water cooled condensers are available on request. Air cooled units can be designed for operation in ambient temperatures up to 48°C.
All units are supplied with non-ferrous pumps (loose on models 7-10).
Evaporators are of copper tube with stainless steel supports. Immersed in the bulk holding tank, they have the advantage of enabling water temperatures down to +1°C to be reached without the addition of antifreeze. Their simple design also enables high or low water flow rates to be achieved, with corresponding pressure and temperature differentials to suit individual applications. Due to the large water reservoir it is possible to maintain stabilised fluid temperatures of +1°C, which will not fluctuate to any great extent, even when process demand exceeds unit capacity for short periods.
All products are fully tested before leaving the works and customers’ own Engineers are welcome at this time in order that they may familiarise themselves with the equipment. Once on-site we can arrange for post commissioning and on site training. For maintenance, emergencies and long term contracts our own Service Engineers are at your disposal.
