Single Room Heat Recovery Units

HRUWALLWI model ductless heat recovery unit comes equipped with a WiFi module. Its basic parameters, including max. heat recovery 82%, airflow rate 60 m3/h, and low sound power level 38 dB (A), are identical to those of the HRUWALL units. Methods for pairing devices and controlling them are different. With the addition of a WiFi module, the device can be connected to a local wireless network and controlled via a mobile app. Moreover, the app allows the pairing of devices by assigning two or more heat recovery units to a group. It is possible to have many groups so that 1 application can serve all HRV units in a building. A temperature sensor and relative humidity sensor are built into the HRUWALLWI, and the app displays their values.

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

The HomEvap adiabatic humidifier is designed for domestic mechanical ventilation systems with a maximum airflow 600 m3/h. Filtered water (Legiosafe®) naturally evaporates on a special matrix, and then the humidified air is distributed to the ventilation duct system and to the connected rooms. The humidification process is regulated by a wireless room controller and a duct sensor. Builtin PTC heater compensates for temperature losses caused by the evaporation process. The housing is made of EPP, while the matrix is made of fiber glass.

HHS wall diffuser for fresh air supply. Male connector with gasket for fast connection with SPIRAL® duct. Powder painted with white RAL 9010 colour which provides additional protection from corrosion in places with high humidity, such as bathrooms. An excellent choice when celling mounting is out of the scope or the interior design requires a wall diffuser. It can be used in offices, residential houses and mounted just under the ceiling as well.
