Scroll compressors are used because they have 50% fewer moving parts than standard piston type compressors. This equates to greatly improved reliability and improved efficiency as well as reducing noise levels to a minimum. The Digitally-based microprocessor can control water temperature to within 1ÂșC of the set point. The controller also permits the user to pre-set different pool and spa water temperatures and it can also prevent unauthorized tampering by the use of locking controls via a Celsius control key. The versatility of the Metran Swimming Pool Heat Pump is again demonstrated by its capability to heat and cool a swimming pool or spa in different climatic conditions. This allows the operator to have full control all year round. The Metran Swimming Pool Heat Pump can warm your pool or spa with the reliability and efficiency of our other heat pumps, but with the flip of a switch, it can also cool your pool or spa to refreshing temperatures during hot summer months. For cooler climates, heating & cooling heat pumps offer unique advantages over the passive defrost models.
The Metran Swimming Pool Heat Pumps are also hot gas defrost heat pumps that are uniquely equipped for an active defrost cycle. Active defrost involves directing hot refrigerant vapor to the heat collector thereby melting accumulated ice away in a matter of a few minutes and then allowing the heat pump to return back to normal heating cycle. Standard defrost heat pumps may remain off for extended periods when defrosting during very cold weather. However, because of the hot gas defrost function on the Metran Swimming Pool Heat Pump it has the ability to continue to operate-even during freezing weather. Hot gas defrost models will extend the swimming season longer than any standard-defrost heat pump. A large variety of Models are available ranging from 4 kW heating output right through to 149 kW heating output which will ensure a suitably sized product can be selected from the calculation chart for any project.By Mel Peatey
