HRUWALL is a singleroom decentralized heat recovery unit for concealed installation. The unit comes with a ceramic heat exchanger which boasts a maximum heat recovery ratio of 90% (the nominal heat recovery ratio is η=74.3% as per EN 1314182011). The energyefficient EC fan changes the running direction every 70 seconds to alternate between air supply and air exhaust. Low energy consumption and extremely low operating noise make this heat recovery unit a recommended solution for nonstop operation. The heat recovery unit has three speed levels to choose from, depending on the size of the area and indoor demands. HRUWALL10025 provides a sufficient air change level in areas up to 19m2. HRUWALL15060 provides a sufficient air change level in areas up to 45m2. We recommend installing the devices in pairs.

HRUWALLRC is a bidirectional ventilation unit, often described as decentralized or pushpull, with regenerative ceramic heat exchanger. It is intended for single room installation, usually installed in synchronised pairs. The heat exchanger material together with its unique honeycomb structure gives a maximal 82% thermal efficiency ratio (74% acc. to 1254/2014 EU Directive reference measuring point). The operating principle is analogous to HRUWALL unit is working in alternating flow mode, switches the air flow directions every 40120 seconds (pushpull) and it’s equipped with energy efficient EC fan (maximum power consumption is only 6 W for HRUWALLRC15060). The unit casing is made of ABS plastic. A remote controller with LCD display is included in the set. We recommend installing the devices in pairs
