9kW Ultra-Low Temp Split DC Inverter Air Source Heat Pump
9kW ultra-low temp heat pump
,DC inverter air source pump
,split heat pump with warranty
Engineered specifically for stable hydronic heating in sub-zero winter conditions, this split-type air-to-water heat pump isolates the indoor hydronic module from severe outdoor elements. Driven by a high-efficiency Panasonic DC inverter compressor, it automatically adjusts operational frequency to match real-time heating loads, providing energy-efficient performance with exceptionally low vibration and operating noise.
Designed as an all-in-one plug-and-play hydronic unit, the RFJ-AW-9DS features an integrated high-efficiency circulating water pump and a built-in 3kW auxiliary electric heater. The integrated electric heater provides an automated boost during extreme cold weather snaps, while concealed shut-off valves streamline installation and maintain a clean overall footprint.
Equipped with an intelligent digital controller and built-in WiFi connectivity, users can easily monitor loop temperatures and configure heating modes remotely via a mobile app. Multi-layer safety protection protocols—including water flow switch monitoring, high/low pressure sensors, anti-freeze routines, and phase sequence protection—ensure continuous and reliable operation.
- Panasonic DC inverter compressor
- High-efficiency plate heat exchanger
- Built-in circulating water pump
- Built-in 3kW auxiliary electric heater
- Concealed stop valves
- Electronic expansion valve
- Intelligent controller with WiFi
- Split-Type Protection: The hydronic plate exchanger and water components remain safely indoors to eliminate freezing risks in low ambient outdoor conditions; connection refrigerant piping between units is excluded.
- 380V Three-Phase Power: Built for 380V/3Ph/50Hz power supply to ensure balanced electrical distribution.
- Cold-Climate Residential Hydronic Heating: Ideal for residential homes, villas, and apartments using underfloor heating loops, fan coil units, or low-temperature radiators in cold northern regions.
- All-in-One Domestic Hot Water & Space Heating: Provides year-round space heating and domestic hot water generation with reliable thermal output, even during severe winter weather.
- Fossil Fuel Boiler Replacement: Replaces traditional gas, oil, or direct electric heating systems to cut carbon emissions and significantly lower monthly energy bills.
