LG Heat Pump Therma V Hydrosplit IWT R32 16kW 3-phase HU163MRB/HN1616Y

LG Therma V Hydrosplit IWT R32 heat pump in 16 kW configuration (external model HU163MRB combined with internal unit HN1616Y) is a split system designed for heating and cooling integrated with a water circuit. The device allows operation with a water outlet temperature of up to 65°C, is designed for three-phase installation, and offers high seasonal efficiency (SCOP 4.55 at LWT 35°C). The pump uses R32 refrigerant with a reduced GWP potential.

The manufacturer of the device is LG, an international company specializing in electronics and heating-cooling systems. LG provides LV/HV solutions with inverter technology and Scroll compressors, combining advanced hydraulic control (built-in flow and pressure sensors, advanced water pump control) with a compact design of external and internal units.
