Nano FI, the mini Full Inverter designed for small pools

The Poolex Nano FI is a compact and reversible heat pump designed to heat or cool pools up to 30 m³. Thanks to its Full Inverter technology, it continuously adjusts compressor and fan power to maintain a stable temperature, reduce energy consumption and limit noise levels.

Its Heat / Cool / Automatic operation extends the swimming season. It ensures fast heating in spring, stabilizes water temperature during mid-season and can cool the pool during hot weather. It operates from -7°C outdoor temperature for extended thermal comfort.

Thanks to its Plug & Play design, the Nano FI installs easily on a single-phase 220–240V power supply. Its ultra-compact format (440 x 430 x 426 mm) allows seamless integration into small spaces: above-ground, semi-inground or inground pools, terraces and compact gardens.

Equipped with a built-in Wi-Fi module, it can be controlled remotely via the Poolex app. Users can set the temperature, select modes and optimize operating cycles directly from their smartphone. Its Twisted Tech® titanium heat exchanger, compatible with salt treatment, ensures durability and corrosion resistance, while its sound level below 35 dB at 10 m guarantees discreet daily operation.

Full Inverter Technology

The Nano FI continuously adjusts compressor and fan speed to precisely match the pool’s actual needs. Unlike traditional On/Off systems, it intelligently modulates its output to maintain a stable and consistent water temperature.

This progressive regulation allows:

  • Faster temperature increase
  • Significant reduction in electricity consumption
  • Reduced thermal fluctuations
  • Quieter and more comfortable operation

Result: optimized thermal comfort and improved energy efficiency.
