European Aesthetic Design
Minimalist design with an aluminum alloy front gives FLIXX large heat pump a harmonious presence in European buildings. More new appearances are on request.
Standardized Installation
With integrated electrical wiring and water connections and key components such as anti-freezing valve preloaded to make installation easier, more efficient.
Optimized Airflow Design
HeatNature is equipped with dual EC fans, an optimized evaporator, and insulated air chambers, which ensure fluid airflow, delivering not only higher transfer efficiency but also a more comfortable experience.
High efficiency
The heat pump compressor is optimized to the local climate. Combined with high-efficiency fans, finned heat exchangers with special flow path design and air ducts designed by fluid simulation, the ErP series has achieved A+++ at both 35℃ and 55℃ based on EN14825/EN14511, a leading level in the heat pump industry. In addition, its SCOP is higher than 5.1 based on A7/W35 EN 14825/EN14511, which means it can work efficiently even in harsh environments.
Solution
We has been committed to practicing the concept of low carbon and environmental protection. After a long period of research and development, finally was found the next generation of environmentally friendly and low-carbon new refrigerant replacement solutions: R290 FLURRY Series Air To Water Heat Pump, which combines multiple excellent features, representing current state-of-the-art heat pump technology.
It is capable of producing house heating and domestic hot ater at the same time, which is regarded as the one-stop energy-saving solution for the whole family.
Integrated core design
for safety, reliablity and precision control
Leakage Detector
By NDIR technology, it detects the leakage of R290 gas in the range of 0~100% LFL with high precision of ±2.5% per second.
R290 Degasser
Releases gas bubbles from the hydronic system when leakage happens in PHE to avoid gas going towards indoor units.
Anti-Freezing Valve (Option)
Designed with a built-in drainage system to release water and prevent freezing when the temperature drops below 3°C.
Refrigerant Exhaust Fan
The ATEX certified fan accelerates the diffusion of R290 gas to avoid its accumulation leading to danger in case of leakage.
Inverter Water Pump
PWM control with default delta T 5°C ensures highly energy transfer efficiency for the hydronic system.
