It's the Min Pro Pool Heat Pump — a compact, inverter-driven air-to-water heat pump designed to heat (and provide limited cooling for) small to medium swimming pools, featuring a patented square design, quiet operation and plug-&-play controller.
There are four models: PW005 (recommended pool volume 5–15 m³), PW008 (10–20 m³), PW012 (12–22 m³) and PW015 (15–25 m³).
At Air 27°C / Water 26°C / Humidity 80%: PW005 heats ~2.8 kW (0.56 kW input, COP 5.0); PW008 ~3.5 kW (0.65 kW, COP 5.4); PW012 ~4.5 kW (0.83 kW, COP 5.4); PW015 ~5.5 kW (1.02 kW, COP 5.4).
Operating air temperature: -5°C to 43°C. Operating water temperature for heating: 9°C to 43°C. For cooling: 9°C to 35°C.
Sound pressure levels at 1 m are approximately 45 dB(A) for PW005, 46 dB(A) for PW008, 47 dB(A) for PW012 and 48 dB(A) for PW015. At 10 m the levels are roughly 28–32 dB(A) depending on model.
The unit uses R32 refrigerant. The compressor brand is Gree; the four-way valve and expansion valve are Sanhua.
It uses a spiral titanium tube heat exchanger encased in PVC, suitable for pool water and corrosion resistant.
Yes — it features a simple plug-&-play electrical design and a press-&-heat controller for straightforward operation. Water plumbing requires a Φ32 mm connection.
Yes — it has intelligent automatic defrosting using a four-way valve to efficiently defrost when ambient temperatures are low, supporting operation down to -5°C air temperature.
Advised water flux: PW005 1.0–1.5 m³/h, PW008 1.5–2.0 m³/h, PW012 1.7–2.2 m³/h, PW015 2.0–2.5 m³/h. Maximum water pressure drop listed is up to 224–44 kPa depending on model/spec configuration.
Power supply: 220–240 V, single phase, 50 Hz. Rated input currents (approximate) by model at Air 15°C are: PW005 ~2.4 A, PW008 ~2.8 A, PW012 ~3.5 A, PW015 ~4.3 A. Ensure appropriate circuit protection and wiring per local code.
Yes — models provide limited cooling capacity (measured at Air 35°C / Water 28°C / Humidity 80%): PW005 ~1.5 kW, PW008 ~2.0 kW, PW012 ~2.6 kW, PW015 ~3.3 kW.
Net/gross weights are approximately: PW005 25/27 kg, PW008 26/28 kg, PW012 33/36 kg, PW015 34/37 kg. Carton and package sizes vary by model (examples: 394×444×435 mm up to 498×499×500 mm). Contact seller for exact shipping/package dimensions per model.
Keep the air inlet/outlet clear of debris, ensure proper pool water chemistry to protect the titanium heat exchanger, periodically check water connections and filters, and have refrigerant and electrical components serviced by qualified personnel when needed.
