The VRF system is available in cooling capacities of 45, 56, 71 and 85 kW. Due to a high APF [Annual Performance Factor], compact installation, light weight, multiple-unit installation, low sound levels, and heating operation at low ambient temperatures, these units can be matched to any required capacity. Heating, cooling and domestic hot water supply can be achieved with only one installation for any type of application. Maintenance costs are low with engine oil change only every 20,000 hours and regular maintenance every 10,000 hours.
* Option for Hydro-module for radiators, fancoils or underfloor heating.
YANMAR GHP CHILLER
Yanmar is the frst company worldwide to introduce a reversible chiller GHP of 71 kW in this power range.
It is an environmental friendly alternative to already existing air-to-air GHPs with indoor units and air-to-water GHPs with hydro-modules.
