Low Temperature Use Heat Pump Water Heater (A02U)

KONNEN AIR SOURCE HEAT PUMP, EVI AIR TO WATER HEAT PUMP ,WORKING TEMPERATURE -30° C--43° C.
* Low-temperature cycle type with great performance of environmental protection, low operating costs, outstanding energy savings, safety and so on.
* Improving performance under cold temperature, safe and reliable - air injection & increase enthalpy products to achieve heating operation whthin-25 ° C - 43 ° C, increaseing the compressor heating capacity in the cold, rising nearly 20% heating capacity under-10 ° C, leading to "strong hot and cold" era. When the temperature is as low as -20 ° C the heat pump can start running and get good effect of hot water supply.

Scope: Hotels, guesthouses, entertainment sauna center, body building club, beauty salon, bathing centers, hospitals, factories, restaurants, dormitories, residential central heating and other hot water useing places.

1, High efficiency
* Energy efficient - the unit uses the world advanced technology - air injection & increase enthalpy systems, high efficiency heat exchanger technology, technology, air injection and enthalpy increase, higher COP in low temperature.

2, Safe and reliable
* Safe and reliable -useing of microcomputer for automatic control, control and fill constant temperature of hot water and ensure water temperature in water tank according to the water level, temperature, which can meet the requirement for all day water using in any time, water and electricity are separated, safe and reliable.
* Microcomputer controlled power-off memory, automatic fault detection, protection timely, more reliable, use more confidence.
* Easy installation - remote controller installation, strong and weak electric be completely separated, operation securely.

3, Energy saving
* Use R417A, R407C refrigerant, ozone depletion factor is zero, green, to meet the national environmental requirements, to eliminate the forbidden risk. (Optional refrigerant R22)
