The heat recovery fresh air device is called HRU or VAM device in short. HRU devices are designed to meet the exhaust and fresh air needs in indoor spaces and thanks to its special plate heat exchanger and with the help of the built-in fans, it provides energy saving by recovering the heat energy without mixing the exhaust air with fresh air.

Product Material

Bearing frame is made of double-walled galvanized sheet with 1,00 mm thickness and inside of device is noise insulated with 30 mm thickness. It has self-powered, imported, silent, mono-phase (230 V) and plug-in fans suitable for speed control. 45-60% efficiency heat exchangers are used in our heat recovery devices.


Ceiling type heat recovery devices are designed to provide high indoor air quality as well as energy saving. Aluminum plate heat exchangers with high performance and thermal conductivity ensure efficient heat transfer between warm and cold air streams. They are devices that provide energy saving advantage as well as meet the need for fresh air at businesses, banks, offices, hotels, houses, cinemas, fair - exhibition areas, hospitals, multipurpose halls, cafes, restaurants and such areas that need to be exhausted too much. They are produced as standard 10 models with air flow range of 500 m³/h to 5000 m³/h. The models are designed to be placed between the suspended ceilings, installed and maintained easily.


- Supplies the required fresh air to indoors and improves the air quality. - Discharges indoor air with low quality. - Utilizes the energy of exhaust air to condition fresh air. - Filters fresh air supplied to the indoor.
