There are two types of condensers used in chillers; air-cooled and water-cooled. An air-cooled condenser uses ambient air to cool and condense the hot refrigerant gas back down to a liquid. It can be located inside the chiller or can be remotely located outside, but ultimately it rejects the heat from the chiller to the air. In a water-cooled condenser, water from a cooling tower cools and condenses the refrigerant. In most process cooling applications, a pumping system circulates cool water or a water/glycol solution from the chiller to the process. This cool fluid removes heat from the process and the warm fluid returns to the chiller. The process water is the means by which heat transfers from the process to the chiller.
As well as chiller servicing, breakdowns and call-outs, we also provide a complete chiller replacement service. The most recent at a site near Bath included a fully insure contract crane lift that we co-ordinated to lift out the old system which was replaced with an energy efficient version providing energy savings of over 30%.
