Commercial heat pump water heater (Direct-heating)- adopts special variable flow rate technology (including water flow, wind flow, refrigerant flow) to overcome the weakness of cycle model products, and ensure the heat pump work steady and low noise, keep water temperature invariableness in the cold climate and hot climate. The quickly de-frosting technology make sure machine work well in the low-temperature, moist environment. Tap water be heatedto 55 one-off by unit, not need to cycle many times, convenient and reliable.ModelRS-18GYRS-38GYRS-75GYRated Input Power4.4 KW9 KW18 KWRated Heating Capacity18 KW38 KW75 KWHeating ampere8.1A16.5A34APower Supply380V 50HzOutlet water temperature55 degreesWater output capacity387 L/h817 L/h1613 L/hCycle capacity (hot value)3.1T/H6.5T/H12.9T/HPressure (kPa)323245RefrigerantR407C/R417ACompressorCOPELANDEvaporatorHigh efficiency finned heat exchangerUnit size(mm)765x765x9501450x705x11751600x1100x1755Unit net Weight (Kg)130250530Noise (dB)606570Water connectionDN15DN20DN25Cycle ConnectionDN25DN40DN65
