PHNIX HeatGreen R290 Commercial Heat Pump

Guangdong PHNIX Eco-energy Solution Ltd. is a Chinese heat pump maker founded in April 2002 and based in Nansha, Guangzhou. It is a national high-tech enterprise focused on heat pump research and manufacturing, and it exports about half of its output to Europe, North America, the Middle East and Australia, offering both its own brand and OEM, ODM and co-design for partners.

The HeatGreen series is a commercial air-source heat pump using natural refrigerant R290 and full DC inverter technology. It supplies hot water up to 75 C without electric backup, operates in ambient temperatures from -25 to 43 C, and lets one central display coordinate up to 16 units so capacity can be added in phases. A plug-and-play 4G module connects units to a cloud platform for remote monitoring, and SG Ready and hybrid modes allow it to work with solar, gas boilers or electric heaters. Typical sites are hotels, hospitals, restaurants, malls and factories.

• R290 refrigerant: natural refrigerant with full DC inverter compressor and fan.
• High water temperature: up to 75 C hot water without electric backup heater.
• Wide operating range: runs at ambient temperatures from -25 to 43 C.
• Cascade control: one central display manages up to 16 units for phased expansion.
• Cloud monitoring: plug-and-play 4G DTU module for remote monitoring and management.
• Hybrid integration: SG Ready and hybrid modes work with solar, gas boilers and electric heaters.

Hotels and resorts in coastal Vietnam could replace LPG boilers with cascaded heat pumps for guest hot water. Hospitals could supply 60 to 75 C sanitary hot water with built-in legionella protection. Factories with large worker dormitories or canteens could pair heat pumps with rooftop solar.

Hotels, hospitals and factories can replace electric or fossil water heating with a heat pump that reaches 75 C without electric backup, which also covers legionella control. Central control of up to 16 units lets owners expand capacity in stages as occupancy or production grows. R290 refrigerant reduces climate impact compared with high-GWP synthetic refrigerants, and cloud monitoring supports remote service.

Commercial buildings are shifting hot water production from electric resistance and LPG to heat pumps, and refrigerant rules are pushing manufacturers toward R290. In Vietnam, hotels, resorts, hospitals and industrial dormitories use large volumes of hot water, and rising electricity tariffs make heat pumps more attractive than resistance heaters.

Guangdong PHNIX Eco-energy Solution Ltd. was founded in April 2002 and is headquartered at No. 3 Tianyuan Road, Nansha, Guangzhou. It exports about 50% of its products to Europe, North America, the Middle East and Australia. Product certifications include CE, UKCA, PED, KEYMARK, MCS, SG Ready and ErP, and in 2026 it received SGS EU Cyber Resilience Act compliance certificates and exhibited at Chillventa 2026.
