New high-capacity heat pumps from Lochinvar
Lochinvar has extended its Amicus range of air source heat pumps (ASHPs) by launching five higher capacity models.
There are now a total of 17 models in the range delivering heating capacities from 7.7kW up to 210kW. Lochinvar is, therefore, able to service a wide range of projects including large residential; medium and large commercial; and industrial applications.
The Amicus heat pump range employs the innovative principle of Enhanced Vapour Injection (EVI) to improve both output and efficiency. This is a two-stage compression process with inter-cooling that produces a superheated vapour to boost capacity and efficiency. As a result, Amicus units can achieve a Coefficient of Performance (COP) up to 4.4 and are 25% more efficient than standard scroll compressor driven systems.
They are also capable of delivering flow temperatures up to 63°C for heating and hot water applications and can operate in outside temperatures as low as -20°C. They can be used as stand-alone replacements for conventional heating products or as part of an integrated system providing pre-heated feed water to gas-fired condensing boilers, water heaters and thermal stores in buildings with large heating or hot water demands.
