Poolex Megaline Fi Inverter Commercial Pool Heat Pump

Poolex Megaline Fi Commercial Pool Heat Pump

High-performance commercial swimming pool heating with advanced inverter efficiency

The Poolex Megaline Fi range has been developed specifically for commercial swimming pools, leisure centres, hotels, therapy pools, holiday parks, and large residential installations where heating costs can become significant.

Using advanced stepless DC inverter technology, the heat pump automatically adjusts compressor and fan speeds according to heating demand. This intelligent modulation significantly reduces electricity consumption while maintaining stable pool temperatures and quieter operation.

The vertical air discharge system reduces acoustic pressure while requiring minimal installation space, making the Megaline Fi suitable for plant rooms and compact technical areas.

Integrated Wi-Fi connectivity allows users to remotely monitor and control system performance using the Smart Life mobile app.

Commercial-Grade Construction and Reliable Performance

The Megaline Fi range is constructed using high-quality stainless steel structural components combined with a powder-coated galvanised steel cabinet for long-term durability in demanding environments.

Each model is equipped with Mitsubishi multi-frequency rotary inverter compressors and DC brushless fan motors to maximise performance, reliability, and energy efficiency.

The Twisted Titanium heat exchanger offers excellent resistance against chlorine and salt-treated pool water, helping ensure long service life in both commercial and intensive-use swimming pools.

The range operates efficiently in outdoor temperatures down to -15°C thanks to automatic hot gas defrost technology, extending pool usage throughout the year.

Intelligent Heating and Cooling Modes

The Poolex Megaline Fi range includes multiple operating modes to suit changing environmental conditions and pool requirements.

Available operating modes include:

• Heating mode
• Cooling mode
• Silence mode
• Automatic mode

The adjustable temperature range allows accurate water temperature management for both heating and cooling applications.

Heating range: 15°C to 40°C
Cooling range: 8°C to 28°C

Smart Controls and Wi-Fi Connectivity

The Megaline Fi range features a high-end multilingual colour LCD touch screen controller designed for simple commercial operation.

The display provides:

• Operating status information
• Temperature settings
• System parameters
• Error codes
• Performance monitoring

Built-in Wi-Fi connectivity enables remote control and monitoring through the Smart Life smartphone app.

Energy-Efficient Commercial Pool Heating

The advanced inverter management system continuously regulates compressor and airflow output based on real-time heating demand.

This intelligent operation helps:

• Reduce energy consumption
• Lower operating costs
• Improve seasonal efficiency
• Minimise compressor stress
• Reduce operating noise

The Megaline Fi range delivers exceptionally high COP performance, helping commercial operators reduce long-term heating expenses.

Installation and Water Connections

All models within the Poolex Megaline Fi range are three-phase units and require installation by a qualified electrician.

Water connections:

• Fi 35: 63mm
• Fi 50 / Fi 70 / Fi 100: 75mm

The units are supplied with unions suitable for pressure pipe installations.

A bypass kit is recommended to optimise water flow, improve heat transfer efficiency, and simplify maintenance or winterisation procedures.

Understanding COP Efficiency

COP stands for Coefficient of Performance and measures the heating efficiency of a heat pump.

A COP of 15.93 means the heat pump can produce up to 15.93kW of heating energy for every 1kW of electricity consumed under specific operating conditions.

Higher COP values help reduce energy consumption and long-term operating costs.
