High Temperature Heat Pumps

High Temperature Heat Pump
The Metran High Temperature Air Source Heat Pumps transfer heat from the ambient air to water, providing high-temperature hot water up to 80°C. The unique high-temperature heat pump is widely used for house warming in the cooler climates as well as Commercial/Industrial applications, particularly in the tropical zones of the World.  With innovative & advanced direct heating technology, the heat pump can operate very well at ambient temperatures as low as 0℃ whilst still being able to generate high output temperatures of up to 80℃.  This ensures compatibility with normal sized radiator, based systems without the need for any supplementary energy source. Compared with traditional Diesel fuel or LPG boilers, the high-temperature heat pump can produce up to 50% less CO2 whilst saving up to 80% in operating costs.  The Metran High Temperature Heat Pumps are not only highly efficient, but are also easy and safe to operate.
Intelligent Digital Controller
The high temperature delivery from this new design of Air to Water Heat Pumps is achieved by using a combination of high efficiency American Copeland scroll compressors, environmentally safe R134a refrigerant, electrically activated expansion valves, larger evaporator design and specially designed high efficiency tube in shell heat exchangers.  A user friendly intelligent digital controller with blue LED back lighting is incorporated with the Heat Pump unit to easily adjust temperature setting to suit any application.  The electrical compartment is provided in a separate, isolated compartment to avoid internal corrosion and subsequently contributing to extending the operational life cycle of the Heat Pump unit.
In all cases each project design, followed by the correct High Temperature Heat Pump model selection is critical in order to maintain the required performance criteria and the durability of the system.  In addition, installation recommendations of clear, unobstructed minimum space clearances around the Heat Pump systems must be observed in order to maximize the performance and minimize the operating costs.  It is also advisable to mount the Heat Pump(s) on a solid concrete foundation and using shockproof bushes at the anchor points to maintain stability of the system, and reduce noise and vibration that may eventually contribute to damage of plumbing the connections.
