Energy Saving Commercial Hot Water Heat Pump KFXRS-76II/A | OEM Supplier

 
Safe and reliable to ensure NO worry use.

Safety is top priority to the commercial hot water machines. TENESUN commercial hot water air source heat pumps adopt a closed design with complete separation of water and electricity and this completely eliminates safety risks such as electrical and water leakage. Furthermore, the machines are equipped with multiple safe protection measures, such as high and low pressure protection, compressor’s over-current and overload protection, start-up delay, water flow protection, water temperature’s high temperature protection and so on to ensure safe operation in any conditions. In addition, there is no need to use fuel delivery pipeline for TENESUN air source heat pumps and it will avoid the risks of fuel leaks, fire and explosion and there is no worry when use.

Scenario-Based Solutions

Hotels, Resorts & Homestays (50–500 Rooms)

In the hospitality sector, guest satisfaction relies heavily on immediate and consistent access to comfortable hot water. The KFXRS-76II/A delivers an impressive continuous hot water capacity of 1644L/h at 20℃ ambient temperature and 1122L/h at 7℃, ensuring that every room receives stable, temperature-controlled water even during early morning check-outs or evening peak shower hours. Additionally, the unit operates at a low noise level of just 67dB(A), preserving a tranquil environment for guests. By upgrading to this air source heat pump, hospitality managers can drastically cut daily energy expenditures, thereby improving overall operational profit margins.

Schools & Hospitals

Educational institutions and healthcare facilities require centralized, ultra-safe water heating systems capable of serving hundreds of users daily without fail. This commercial heat pump is equipped with multiple integrated safety mechanisms, including high/low-pressure protection, compressor over-current/overload protection, and precise water flow monitoring. These features effectively eliminate critical risks such as electric leakage or system overheating. Furthermore, its broad operating temperature range of -15℃ to 45℃ guarantees uninterrupted hot water supply throughout freezing winters, providing reliable daily support for students, patients, and medical staff.

Large Factories & Enterprises

Industrial dormitories and corporate office buildings need cost-effective welfare solutions for their workforce. The KFXRS-76II/A heat pump can reduce hot water energy costs by up to 50% compared to traditional electric heaters, thanks to its exceptional COP values (4.69 at 20℃ and 3.92 at 7℃). By replacing legacy fuel-powered boilers, facility managers can entirely avoid fuel leakage, fire hazards, and explosion risks. The system also features remote intelligent control capabilities, allowing maintenance teams to monitor operations and adjust settings off-site, which can improve facility management efficiency by up to 80% and reduce on-site labor requirements.

Core Product Features

Ultra-Efficient Energy Saving

Utilizing advanced air-source heat recovery technology, this unit absorbs free thermal energy from the atmosphere and transfers it to the water supply. It requires only a fraction of the electrical input used by standard electric water heaters. With a COP reaching 4.69 (at 20℃ ambient) and an Annual Heat Performance Factor (AHPF) of 3.85, the system maintains superior energy efficiency across variable seasonal temperatures, effectively cutting operational heating costs in half.

Stable & Reliable 24/7 Operation

Engineered for continuous, heavy-duty output, the large-capacity design easily adapts to fluctuating daily usage patterns, seamlessly transitioning from low-traffic periods to sudden peak-hour surges. The system remains fully operational in extreme weather conditions (-15℃ to 45℃) and incorporates start-up delay protection to prevent compressor damage, ensuring long-term durability and consistent performance in demanding environments.

Safe & Environmentally Friendly

The innovative closed water-electricity separation structure physically isolates electrical components from the water circuit, completely eliminating electric shock hazards and meeting stringent commercial safety regulations. Because it operates without combustible fuels or gas pipelines, it removes the fire and explosion risks associated with traditional boilers. Its zero-emission operation strongly supports corporate sustainability and green building initiatives.

Intelligent & Low-Maintenance

Designed for modern facility management, the integrated smart control system enables real-time performance monitoring, parameter adjustments, and instant fault notifications via connected devices. This data-driven approach provides valuable usage insights to further optimize energy consumption. The modular, easy-access design simplifies routine maintenance, significantly reducing system downtime and professional repair costs over the equipment's lifespan.
