Helios Fans KWL 360 W

The Helios KWL 360 W is an electrical preheater specifically developed to support mechanical ventilation with heat recovery (MVHR) systems in cold climates. Designed for simple plug-in installation, this unit preheats incoming outdoor air before it reaches the main heat exchanger, ensuring reliable operation and preventing freezing during very low temperatures.

With a heating output of 1500 W, it provides effective anti-icing protection, helping maintain consistent ventilation performance and system longevity. The KWL 360 W is especially critical for use in passive house installations, where uninterrupted and energy-efficient ventilation is a requirement.

This accessory integrates seamlessly with Helios ventilation units and offers a practical solution for maintaining optimal indoor climate conditions even in harsh winter environments.
