The KFXRS-40 II P/C Energy-Saving Commercial Hot Water Pump is a compact yet powerful commercial air source heat pump designed for mid-size establishments seeking efficient, reliable hot water supply. Developed by TENESUN, it integrates advanced air-source technology to absorb free heat from the air, outperforming traditional electric and gas water heaters by consuming only 1/4 the electricity of electric heaters and 1/3–1/2 the energy of gas heaters.

Mid-size hospitality venues need efficient hot water solutions that don’t compromise guest experience. The KFXRS-40 II P/C Energy-Saving Commercial Hot Water Pump delivers 860L/h (20℃) and 589L/h (7℃) hot water capacity, ensuring steady supply for guests while reducing energy bills significantly. Its low noise range (52–63dB(A)) maintains a peaceful atmosphere, and the IPX4 waterproof rating makes it suitable for outdoor installation—saving indoor space for other facilities.
Community hospitals and small-to-mid-size school dormitories require safe, centralized hot water for staff, patients, and students. The unit’s zero-safety-risk design (water-electricity separation, over-current/overload protection, water temperature protection) ensures safe usage for vulnerable groups. Its wide operating temperature range (-15~45℃) and stable COP (3.91 at 7℃) guarantee reliable performance in cold climates, eliminating concerns about hot water shortages during winter.
Gyms and swimming pools have high-frequency hot water needs for post-workout showers, while small factory dormitories require cost-effective employee welfare solutions. The KFXRS-40 II P/C Energy-Saving Commercial Hot Water Pump meets high-cycle usage demands with its continuous output, and its energy-saving technology cuts utility costs by 50%. The R410A refrigerant ensures environmental friendliness, aligning with green business certifications, and the easy-maintenance design minimizes downtime—critical for businesses operating long hours.
Captures free atmospheric heat for water heating, reducing energy consumption drastically compared to traditional systems.
COP ranges from 4.05–4.69 (20℃ ambient) and 3.48–4.26 (7℃ ambient), with an AHPF of 3.85, ensuring consistent efficiency across usage scenarios.
Sleek dimensions (1200×430×1550mm) and net weight of 170kg allow installation in tight spaces (e.g., roof terraces, utility rooms) without sacrificing performance.
DN40 pipe diameter and 72kPa water pressure drop adapt to existing plumbing systems, reducing renovation costs for businesses.
Comprehensive safety protections (high/low pressure, water flow, over-temperature) eliminate electrical and fire hazards, meeting commercial compliance standards.
R410A refrigerant is ozone-friendly, and no fuel combustion means zero emissions—supporting sustainable business practices.
Remote intelligent control enables off-site management, allowing users to adjust temperature, monitor usage, and troubleshoot issues via digital devices.
Data-driven operations provide insights into energy consumption patterns, helping businesses optimize usage and reduce waste.
