At Poolex, we understand that heating is a fundamental issue for communities and that it represents a major expense. This is why we designed the Megaline Fi heat pump..

Thanks to its components selected from the biggest brands on the market, as well as intelligent electronic management, the Megaline Fi adapts itself to the most demanding conditions of use.

It is equipped with the latest generation of Mitsubishi multi-frequency rotary compressors optimizing its energy efficiency. Combined with controlled electricity consumption, this affords the Megaline Fi with one of the best COPs on the market. The fan modulates its speed according to the temperature of the evaporator in order to deliver only the necessary air flow. This intelligent management of the power supplied greatly reduces power consumption and operating noise.

The upward ventilation of the Megaline Fi also lowers the sound pressure. This type of ventilation requires little installation space and the heat pump can be installed close to living places.

Its large multilingual control panel displays all the information necessary for ease of use. The advanced functions also allow viewing of the history of states and error codes. Control of your heat pump is at your fingertips: receive all the important information directly on your smartphone, wherever you are, thanks to the WiFi connection.

Equipped with a stainless steel casing and structure, the Megaline Fi is ready to meet any challenge.

A Poolex innovation, the Megaline Fi includes a structure designed to be lifted and handled, thus facilitating its installation.

Tailor-made support, from sizing to maintenance is possible thanks to our network of partner installers regularly trained for this type of product.

full inverter technology +35% energy savings

Popular in the domestic heating and air conditioning sectors, Full Inverter technology adjusts precisely the fan and the compressor, turning the heat pump into a smart pump.

Unlike a traditional heat pump, the Full Inverter compressor starts up gradually. If the set temperature is far from the swimming pool actual temperature, an automatic regulator boosts the heat pump’s capacity for a quick rise in temperature. During swimming season, and to maintain the set temperature, the heat pump operates at reduced power.

This constant operation means that the Full Inverter heat pump operates in a more stable way and preserves the compressor from unwanted starts and stops, resulting in energy savings of over 35%.

multiple mitsubishi rotary compressors

As a large volume heat pump, the Megaline Fi is equipped with multi-frequency rotary compressors, creating the necessary compression of the refrigerant gas for the heating and cooling action.

This type of compressor optimizes the operation of the heat pump, resulting in a COP of around 7.5 and considerably reducing the noise level.

stainless steel structure and powder coated galvanized steel panels

The optimization of the Megaline Fi is thought right through to the packaging of the HP. The structure is designed in stainless steel and the ventilation panels in powder coated galvanized steel. Materials and finishes recognized for their weatherproof quality and their resistance against corrosion. Outdoors, in the mountains and by the sea, the Megaline Fi is made of the best materials to cope with all climatic and environmental conditions.

astonishing acoustic performances

Full Inverter technology, oversized compressor and variable speed fan on the Megaline Fi do not only influence the performance of this large volume heat pump. These components, associated with upward ventilation, play an important role in the acoustic performance of the heat pump. Emitting vibrations comparable to a television set at 1 meter and whispering at 10 meters, the Megaline Fi amazes with its silent side.

integrated wifi connection

Because a heat pump, regardless of its capacity, must be as easy to use, the Megaline Fi can be controlled via your smartphone over Wi-Fi using a control panel located on the pump.
