Product Benefits
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.
Smart Connectivity
Thanks to its built-in Wi-Fi module (2.4 GHz), the Nano FI can be controlled remotely via the Poolex app.
You can:
- Adjust the temperature
- Select Heat / Cool / Automatic modes
- Optimize operating cycles
- Monitor performance in real time
Simple and intuitive control for a pool that’s always ready.
Plug & Play Installation
Designed for quick and easy commissioning, the Nano FI connects directly to the existing filtration circuit.
It operates on a standard single-phase 220–240V power supply and is ready to use immediately.
- Time-saving installation
- Compatible with above-ground, semi-inground and inground pools
- Ideal for small spaces
Result: a high-performance heat pump ready to operate.
Ultra-compact format and discreet design
With its compact dimensions (440 x 430 x 426 mm), the Nano FI integrates easily into small spaces.
Its modern design blends harmoniously into all outdoor environments.
Its sound level below 35 dB at 10 m ensures quiet operation.
Result: maximum performance, total discretion.
Reversible Heat / Cool Function
The Nano FI offers three modes: Heating, Cooling and Automatic.
During mid-season, it ensures efficient temperature increase. In summer, it prevents pool overheating.
Automatic mode maintains a stable temperature without manual intervention.
Result: comfortable water throughout the season.
