GEA Heat Exchangers has launched a reversible air heat pump range designed for outdoor installation.
The GEA GLAH 2015-4120 CDA range covers a total of 21 models, from 42 to 350 kW in heating mode, and 38 to 335 kW in cooling mode.
The company claims the new heat pumps provide greater efficiency in cooling and particularly in heating mode, compared with the previous versions.
The heat pumps operate with R-410A refrigerant and feature one refrigeration cycle with two scroll compressors, or two refrigeration cycles with four scroll compressors, depending on the model.
The available equipment versions offer a choice between the cost-effective standard versions for air-intake temperatures down to -5 deg C in heating mode, and the more efficient high-efficiency versions (HE).
The HE models feature electronic expansion valves and satisfy the stipulations of Eurovent Class A in heating mode.
For the HE models there is also the option of extending heating operations down to an air-intake temperature of -10 deg C.
All the heat pumps in the new series provide the option of having a hydraulic module integrated into the unit.
The one or two water pumps in this hydraulic module can also be ordered if required in a more powerful version for greater pump delivery heads.
