HPA12 (60 Hz, Centrifugal)
Air Source Heat Pump
For Water Heating
General - Colmac HPA heat pumps can be successfully applied wherever there is a need for
large amounts of hot water and there is a source of warm air available. The Colmac HPA is best
suited for supplying hot water in facilities where demands for hot water and space cooling are
concurrent.
Apartments, Condominiums, Hotels, Hospitals, Dormitories, Restaurants, Nursing Homes,
Laundries, Kitchens, Food Processing Plants, and Photographic Processing Plants located in
warm climates are a few of the possible heat sources that can be utilized by the HPA heat pump.
Depending on the temperature of the waste heat source, the HPA can produce potable hot water
for as little as 1/4 the energy used by a conventional boiler or electric resistance heater.
These packaged air source water heating pumps are factory wired, charged, and tested. Low
operating noise levels, high capacity, high efficiency, and environmentally safe refrigerants are
integrated into this new design.
