75 ℃ High Temperature Air Source Heat Pump FKH-40IIGW

The Leomon FKH-40IIGW is a cutting-edge 75 ℃ High-Temperature Air Source Heat Pump. At its core, this system operates on the highly efficient inverse Carnot cycle, effectively extracting low-level heat from the air to deliver high-grade thermal output.

This unit's exceptional performance is powered by its innovative double-stage compression technology, featuring dual compressors that operate alternately. This design not only guarantees stable operating pressure but also prevents overload, ensuring consistent and reliable heating, cooling, and hot water supply. The FKH-40IIGW excels even in challenging climates, maintaining optimal function down to -20℃ ambient temperatures, providing a robust solution for year-round demands.

1. Unwavering Stability & Reliability

With its innovative double-stage compression technology and the strategic use of dual compressors working alternately, the system maintains remarkably stable operating pressure and actively prevents overload. This robust design is further fortified by multiple self-inspection and protection functions (11 equipment self-check protections including compressor exhaust temperature and high/low pressure protection), ensuring continuous, safe, and dependable operation.

2.Exceptional Efficiency & Energy Conservation

Consistently maintains high energy efficiency, particularly in extremely cold environments, demonstrating minimal capacity attenuation of no more than 10%. This ensures consistent thermal matching at lower ambient temperatures and higher heating water temperatures, leading to substantial energy savings and reduced operational expenditure compared to traditional heating methods.

3.Intelligent Control & Seamless Connectivity

Experience unparalleled convenience with advanced 5G cloud technology integration. This empowers users with comprehensive remote monitoring capabilities, allowing for real-time performance oversight and proactive fault diagnosis from any location. The system also supports efficient online maintenance, and its intelligent zone defrosting feature further optimizes heating efficiency while ensuring stable water temperature by selectively defrosting only when and where needed.

4.Enhanced Indoor Air Quality

As an air source heat pump, the FKH-40IIGW operates by transferring heat rather than burning fuel. This means it does not produce fumes, carbon monoxide, or other combustion by-products, making it a significantly healthier and safer option for indoor environments and ensuring superior indoor air quality without the risks associated with fossil fuel heating systems.

5.Unmatched Flexibility for Year-Round Comfort

The FKH-40IIGW offers exceptional versatility, capable of providing heating, cooling, and high-temperature hot water supply from a single unit. This multi-functional capability ensures year-round comfort and meets diverse seasonal demands, providing a comprehensive and highly adaptable climate control solution for a wide range of commercial and industrial applications.

1. Residential Use (Large-Scale & Multi-Unit): 

Ideal for larger residential complexes, apartment buildings, and multi-family dwellings seeking energy-efficient heating and cooling solutions with enhanced comfort features. It provides centralized, reliable high-temperature hot water supply, improving overall living comfort while significantly reducing energy consumption compared to traditional systems.

2. Commercial Buildings: 

Perfectly suited for offices, retail spaces, hotels, and other commercial applications where precise temperature control, exceptional energy efficiency, and low operational noise (≤60dB(A)) are paramount. It ensures a comfortable environment for occupants while contributing to substantial energy savings.



3. Institutional Settings: 

A highly effective solution for schools, hospitals, and government buildings requiring consistent indoor climate control and reliable high-temperature hot water. Its stable performance temperature ensures uninterrupted service, critical for these essential facilities.

4. Industrial High-Temperature Heating Solutions:

Delivering 60–85°C thermal fluids, this system sustains critical industrial processes including electroplating bath insulation, degreasing, and drying, lowering per-unit electroplating costs by 25–35% while enhancing process consistency for printing, dyeing, and textile sectors.

5. Prefabricated Construction Curing Acceleration:

Accelerating cement curing through 65–80°C high-humidity steam chambers, this solution reduces production cycles by 40% for precast concrete elements, ensuring structural integrity while minimizing energy consumption in prefabrication workshops.

Q1.What measures should be implemented if a high-temperature heat pump  experiences unstable network signals or malfunctions in its mobile application interface?

A: Prioritize establishing a reliable network connection to enable seamless remote monitoring.If connectivity issues persist, initiate remote diagnostics via the manufacturer’s IoT platform or contact authorized service providers for on-site technical intervention.



Q2.Is the cleaning process for complex?

A: No. Annual maintenance requires only rinsing the external unit’s air filter—a procedure identical to residential air conditioners. No disassembly of internal components is necessary.



Q3.How should frost accumulation affecting heating performance be addressed?

A: Reduce frosting rate by optimizing fan speed (≤600 RPM) or increasing fin spacing (≥2.5 mm).

For installations in high-humidity regions (>70% RH), deploy reverse-cycle defrosting or hot-gas bypass defrosting systems.

Q4. What is the minimum order quantity (MOQ) ?

A: 1 units.

Q5. Do you provide OEM or private labeling?

A: Yes. We offer OEM/ODM services, including: Logo printing and Custom packaging.

Q6. Do you offer technical training and support?

A: Yes. We provide: Online and on-site training for sales and technicians, Detailed installation manuals and wiring diagrams, Troubleshooting guides, Remote video support during first installations,  etc.
