Product Features and Advantages
Wide Application Ranges
The heat pump is designed for domestic hot water for a houses, as well as small commercial buildings such as small offices, schools, apartments etc. The hot water outlet range is wide from 20℃ to 60℃, meeting demands for most hot water project. The performance is at wide ambient temperature range from -10 to 45℃.
High Efficiency-assuring Grants from Your Government
Designed with high COP over a lifetime of operation, the annual average COP is up to 5.0. Efficiency state is in accordance with government standard.
The Tube in shell heat exchanger as condenser, with bigger heat exchanging area and higher efficiency.
The hydrophilic fin-tube heat exchanger has big heat exchanging area and rational fin distance, thus significantly improves heating and defrosting efficiency.
Durable and Long Life
High efficiency compressor, with durable features against high temperature and high pressure for long life. The coaxial coil heat exchangers are durable for anti-corrosion, hard water, high pressure and unexpected freeze caused by power cut-off.
Strong Cabinet
Standard unit fabrication consists of heavy gage galvanized sheet metal cabinet construction that provides maximum strength. All interior sheet metal surfaces are powder-painted for maximum corrosion protection to ensure resilience for long term vitality. ABS and stainless steel cabinet available.
Famous brand Circulation pump
e.g. Wilo.
Full Consideration for Noise Control
Compressor rubber feet are specially selected for reducing vibration. Specially, compressor sound jacket is available for every unit.The exterior motor fan, with multiple fan blades, is strictly balanced. The multiple fan blades run slower, and make sure high air volume, thus largely brings down the noise.
