Product Information

Overview

Model O is a high-performing lightweight thermal wheel designed for air handling units, primarily for comfort ventilation applications. Typical temperature efficiencies are up to 90%.

Model O is ideal for installation in new air handling units or retrofitting in older units. The wheel is available for both vertical and horizontal assembly.

Model O is certified according to Eurovent and AHRI.

Model O is also available with a casing it is then called Model E.
