The Helios Fans KWL EC 1200 S Pro WW is a compact, floor-standing central ventilation system featuring heat recovery, suitable for residential, commercial, and industrial settings. It is equipped with two quiet, high-efficiency EC fans with backward-curved impellers, delivering excellent energy savings. The advanced control system allows for either constant airflow or constant pressure regulation, providing flexible operation.
The unit supplies filtered outdoor air through a F7 filter, while extract air passes through an M5 (F5) filter before reaching the aluminium cross-counterflow heat exchanger, which offers up to 90% heat recovery efficiency. All filters are pressure monitored and designed for easy removal and replacement.
Designed for easy maintenance, the large surface heat exchanger can be quickly removed. An optional integrated water heater battery is available to enhance heating capabilities, making the unit suitable for diverse ventilation and climate control needs.
