Heat recovery unit WALLER series

The WALLER series recuperator is designed for ductless ventilation of spaces such as: a room, office space, cafe, etc. This device is intended for wall installation. Thanks to the use of a reversible fan, WALLER is a complete supply and exhaust air device, enabling energy recovery from the exhaust air. WALLER can also operate in ventilation mode, as either a supply or exhaust-only device. In such a case, complete mechanical supply and exhaust ventilation can be provided by, for example, two WALLER devices operating synchronously, where one delivers fresh air to the room, and the other handles the exhaust of stale air. However, it should be noted that for devices operating in ventilation mode, energy recovery does not occur. The recuperator is controlled using a remote control, which significantly facilitates managing its operation.
