Heat pump Poolex 5 KW Reversible Nano B5 | PC-NANO-B5
The pleasure of swimming at the perfect temperature, all year round
Nothing ruins a relaxation plan more than finding the pool water too cold or, in the middle of summer, too hot. Maintaining thermal comfort is often costly or complicated in small spaces. The new Poolex Nano Reversible comes to solve these problems in an intelligent way, offering efficient air conditioning that does not require complex installations or large technical spaces.
.
Intelligent connectivity
Controls the heat pump remotely thanks to the Integrated Wi-Fi and to the App Poolex. You can turn on, turn off or adjust the temperature of your pool from your smartphone, no matter where you are.
Reversible hot/cold
Heat the water on cool days or cool it in summer: the Nano adapts. Its cooling mode is ideal in case of high temperatures to keep the water at the desired temperature and protect the liner.
Automatic defrosting
An intelligent program activates defrosting according to humidity and outside air temperature, without the need for intervention. The cycle is completed in less than 10 minutes, optimizing consumption without manual intervention.
.
Compact format
Designed for small pools and tight spaces, the Nano installs anywhere without compromising performance.
