Product Description
31KW-90KW R32 On/Off Swimming Pool Heat Pump for commercial use.

1.Designed with cooling and heating function,can keep the water temperature constant for pool
2.Suitable for commercial and industrial use,
3.Compact structure, quiet and easy to install.
4.Patented corrosion resistant titanium exchanger
5.Eco-friendly
6.High COP
7.Suitable for Koi ponds as well as swimming pools or sauna or spa.


Wotech Commercial Swimming Pool Heat Pumps are widely used in public places all over the world, such as hotels schools, aqua parks, gyms, etc.

★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.
