KFXRS-76II/A Commercial Hot Water Heat Pump

 
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)

For hospitality businesses, guest experience hinges on consistent hot water access. The KFXRS-76II/A Commercial Hot Water Heat Pump provides continuous hot water supply with a hot water capacity of 1644L/h (20℃) and 1122L/h (7℃), ensuring every guest enjoys stable, temperature-controlled water—even during peak hours like morning check-outs or evening showers. Its low noise level (67dB(A)) preserves a quiet environment, while energy efficiency cuts long-term utility bills, boosting profit margins for hotels and resorts.


Schools & Hospitals

Schools (primary, secondary, and university dormitories) and hospitals (comprehensive and community) require centralized, safe water supply for hundreds of users daily. The unit’s multiple safety protections—including high/low pressure protection, compressor over-current/overload protection, and water flow protection—eliminate risks like electric leakage or overheating. Its wide operating temperature range (-15~45℃) ensures reliable performance in cold winters, guaranteeing uninterrupted hot water for students, staff, patients, and medical personnel.


Large Factories & Enterprises

Industrial dormitories and office buildings need cost-effective hot water solutions for employee welfare. The KFXRS-76II/A Commercial Hot Water Heat Pump reduces energy costs by up to 50% through waste heat recycling and high COP values (4.69 at 20℃, 3.92 at 7℃). It replaces traditional fuel-powered systems, avoiding fuel leakage, fire, and explosion risks, while its remote intelligent control allows facility managers to monitor and adjust operations effortlessly—saving time and labor on on-site management.


Core Product Features


Ultra-Efficient Energy Saving
