Heatex Multi Fan


Heatex Multi Fan – 1100+kW

Enabling positive energy

Optimum thermal output


Thermally and electrically efficient Heatex, using hot water heating medium from a boiler, engine or heat pump.

High duty cycle, energy efficient, robust and reliable Heatex unit designed for drying and space-heating applications. Heatex Multi Fan facilitates the transformation of primary or residual heat into valuable energy. Heatex MF offers at least 20% lower energy requirements than other units in the market, delivering savings which really add up throughout the year.
