Neptune Series - Variable Frequency Low Temperature Air Energy Heat Pump (Chilled Water) Unit

Neptune series variable frequency low temperature air energy heat pump water heater unit is a circulating heating heat pump unit. The unit is connected to the insulated water tank through water pipes and water pumps, allowing water to circulate and heat in the system, gradually producing hot water and storing it in the insulated water tank for use when needed. This product is designed for low temperature environments, and can effectively heat in -35C low temperature environments. The maximum water temperature can reach 60 ° ℃, meeting the domestic hot water needs of hotels, schools, factories and other places.
