Recessed Wall

The OSMO Recessed Wall fan coil offers a high level of fit and finish for a low wall fan coil. With the fan coil recessed into the wall only the sleek front panel is visible, providing a clean and slim design with a paintable all metal cabinet, making it ideal for discerning clients and demanding architects.

Utilizing DC inverter technology for super quiet and efficient operations, the OSMO Recessed Wall coil is compatible with low-temperature generators like heat pumps, condensing boilers, and integrated systems with solar panels.

It achieves and maintains the desired temperature swiftly and silently, thanks to the continuous automatic modulation of the fan, delivering efficient and unobtrusive heating.

OSMO Recessed Wall is available in two heights, standard at 23.5“ and low at 15”.
