High-End Market Professional Manufacturer Big Heat Pump Air to Water China

Product Description

70KW Hospital water using heating machine
CANOVA cycle heating heat pump are designed for offering hot water for commercial use, such as office, workshop, super market, school, etc. In order to achieve the required water temperature, large heat pump units apply Unique "V" style evaporator design is a big strongpoint for this unit. It increased the evaporator space in air flow direction, which results bigger effective air volume. It had been proved to be better efficiency by our testing. This design is also easier for the defrosting water to drain out. Scroll compressor is standard for this series.
