The HS Series R290 air/water inverter heat pumps are designed for high-capacity residential and light commercial applications, combining natural refrigerant technology, wide operating range, and robust system protection. With heating output up to 54.2 kW and hot water temperature up to 75°C, the HS Series delivers reliable performance even in extreme low-temperature environments.
HS Series R290 Air/Water Inverter Heat Pumps
The HS Series R290 air/water inverter heat pumps are engineered for applications requiring higher heating capacity, stable year-round operation, and enhanced system protection. Using R290 natural refrigerant (GWP = 3), the series aligns with current and future environmental regulations while maintaining high energy efficiency.
Designed for heating, cooling, and domestic hot water production, the HS Series supports a maximum outlet water temperature of up to 75°C, making it suitable for both new installations and renovation projects. The system remains operational at outdoor temperatures down to –25°C, ensuring dependable comfort in cold-climate regions.
With corrosion-resistant casing treatment and multiple operational protections for heating, cooling, and defrosting, the HS Series is well suited for residential blocks, commercial buildings, and energy-demanding applications where durability and reliability are critical.
The HS Series integrates DC inverter technology with a carefully engineered refrigerant circuit to achieve both efficiency and stability. The system reaches ErP energy efficiency class A++, supported by intelligent climate compensation curves that automatically adjust water temperature according to ambient conditions.
Twin rotary DC inverter compressors, specifically designed for R290 refrigerant and installed in tandem configuration, ensuring smooth capacity modulation and high reliability
EC brushless axial fans with airfoil blades, dynamically and statically balanced to optimize airflow while reducing noise and vibration
Copper-brazed refrigerant circuit, with every unit undergoing pressure testing, leak testing, and online operation testing before leaving the production line
Automatic refrigerant charging system, ensuring precise R290 filling for optimal system performance
The HS Series also incorporates an intelligent compressor operation compensation function, improving system stability under varying load conditions and reducing unnecessary stress on core components.
With its high heating output range (up to 54.2 kW), strong low-temperature capability, and integrated system protections, the HS Series represents a robust R290 solution for medium-to-large air-to-water heat pump applications.
