Product Description
4.5kw-31kw CE/CB R32 Residitial on/off Swimming Pool Heat Pump with wifi function
1.Anti-UV Plastic ABS corrosion resistant casing
2.High COP.
3.Patented corrosion resisant titanium exchanger
4.Environmental friendly
5.LCD or colorful LED controller for options.
5.Re-start memory
6.Heating and cooling with reversible defrosting.
7.Super quiet
8.WIFI APP control(optional)
9.Suitable for Koi ponds as well as swimming pools or sauna or SPA. 
★The world's top heat pump compressor
Adopt international famous brand, are enhanced vapor injection technology,reaching the highest level of efficiency within the air source industry. The strong kernel and high stability ensure the long life of the unit and save more operating cost.
★Titanium Heat Exchanger
We use the Titanium heat exchanger with constructed of titanium shell and tubes, making it the perfect choice for a reliable and effective titanium heat exchanger pool heater. The titanium pool heat exchanger enables indirect heat transfer between any boiler and pool or spa circuit, making it ideal for various applications.
★Nanometer high gold plating evaporator
Compared with plain films and louver fins,the hydrophilic concave-conves fins possess higher thermal efficiency. The corrugated structure makes condensed water turn into channels easily and accelerates the water discharge. Defrosting is effective. The evaporator gets rid of freezing.
★ Fan and Motor
The high quality of the fan and motor system ensures a quiet and stable working condition and sufficient air for heat exchange.
★Auto Defrosting System
★ Wiring connection/Plug-and-Play Motherboard
Clear and inner wiring connection provides convenience of installation and further maintenance. 
Wide working temperature range-Extend swimming seasons:
1.High coefficient of performance with titanium heat exchangers, precision temperature control
2.Low noise compressors and fans in a compact unit help extend the swimming season by supplying an extremely efficient
3.Economical and environmentally friendly heating solutions
