The 75 ℃ High-temperature Heat Pump FKH-40IIGW is an advanced air source solution engineered to provide versatile thermal regulation for various commercial and industrial applications. Utilizing the inverse Carnot cycle, it efficiently transfers low-level heat to produce hot water up to 75℃, while also offering capabilities for heating and cooling. This system stands as a testament to energy-saving innovation, ensuring stable, reliable performance with a focus on long-term operational efficiency and reduced environmental impact.
Minimizing Comprehensive Attenuation in Low-Temperature Environments:
The high-temperature heat pump system is designed to maintain a total performance degradation of no more than 10%, even under challenging low-temperature conditions. This ensures that the system retains its high energy efficiency, consuming less electricity to provide the same heating output, and delivers stable and dependable performance across its entire operational range.
Unwavering Stability and Reliability:
Featuring a robust double-stage compression system with dual compressors, the unit is engineered for highly stable operation. It incorporates 11 equipment self-check protections that continuously monitor the system, promptly detect any anomalies, and activate safeguards to ensure optimal safety and minimize potential downtime.

Durable Stainless Steel Construction:
Built with a high-quality stainless steel sheet metal design, the FKH-40IIGW boasts exceptional heat and corrosion resistance. This robust construction not only ensures long-term durability and a pristine aesthetic but also guarantees a remarkable service lifespan of 10-15 years, minimizing the need for frequent replacements and maintenance.
Optimized Gold Aluminum Condensation Process:
Utilizing sophisticated gold aluminum wing film evaporation technology, the heat pump significantly improves air evaporation efficiency. This process ensures uniform and sufficient heat exchange, maximizing the absorption of heat from low-temperature ambient air sources, thereby boosting overall system performance and energy efficiency.
Intelligent and Convenient Management:
Leveraging advanced 5G cloud technology, the heat pump supports comprehensive remote monitoring, enabling users to oversee system performance from anywhere. It also facilitates efficient fault diagnosis and allows for streamlined online maintenance. Furthermore, the intelligent zone defrosting system accurately determines frosting conditions, performing defrost cycles only when necessary to maintain stable water temperature and improve heating efficiency.

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.
