The unit adopts R32 environment-friendly refrigerant with lower GWP, which is non-toxic and stable, with small pressure loss and good heating performance. Complies with EU F-Gas phase-down requirements.
DC Inverter Technology – A+++ Ultra Efficiency
DC inverter heat pump is more efficient than on/off heat pump, can save energy and save electricity. Twin-rotor DC inverter compressor boosts overall efficiency by 30%, with quieter operation and longer lifespan. BLDC motor fan with system efficiency up to 85%.
IoT Smart Control
Integrated smart control with remote monitoring, data analytics, and climate-adaptive curves. With IoT Technology the heat pump status can be monitored remotely. When a failure occurs, it is possible to check and control remotely the unit's information, providing immediate support. With OTA (update over air) Technology, software updates can be deployed remotely.
Modular Parallel & Rotation Operation Technology
Supports up to 8 water heater modules of the same model in parallel, controlled by one wire controller. Rotation operation intelligently balances running time between units, avoiding excessive operation and greatly extending service life. Rotational defrosting controls defrosting units in batches and stages, avoiding excessive water temperature fluctuation and improving comfort.
Ultra-Quiet Operation
Compared with water heaters equipped with original scroll compressors, noise can be reduced by 8–10 dB(A). Creates a peaceful working and living environment.
Wide Power Supply & Wide Temperature Ranges
DC inverter module adapts to voltage fluctuations of ±20% of the electricity grids, and also adapts to 50/60Hz power supply specifications. Wide ambient temperature and water temperature operating ranges support both hot water and cool water generation.
Smart Defrost Logic
Optimized defrost control increases effective heat output compared to conventional systems, ensuring uninterrupted hot water supply.
Modular Parallel & Rotation Operation Technology
Supports up to 8 water heater modules of the same model in parallel, controlled by one wire controller.
