Topvex FR03-11 is a series of efficient ventilation units designed for offices, shops, schools, daycare centres or similar premises. The units are especially designed to meet the coming energy requirements and have therefore a very low energy use and high efficiency rotating heat exchangers. To simplify the installation and commissioning the units are included with control system and pre-configured.

The unique design with double rotating heat exchangers makes the unit very flat. No need of condense water drainage makes the unit very flexible to install. Topvex FR can be mounted flat on the floor, hanging upside down in a false ceiling or standing on the long side.

The units casing is made in double-skinned 1,0mm aluzinc sheet metal (AZ 185) with internal sound/thermal mineral wool insulation. Two large inspection doors facilitate inspection and maintenance. The fans and the rotating heat exchangers are removable. Supply and extract air filters are mounted in frames and to provide optimal sealing, fitted with ceiling stripes.

The separate electrical box facilitates services. All electrical connections are done at one place in the electrical box.

With the integrated control system it is possible to supervise/control the airflow, duct pressure, temperatures, heating/cooling recovering and the ventilation systems operating time. Topvex FR has also other energy saving functions like free cooling, cool recovering, and season related temperatures and airflow controlling.

Topvex FR is as standard equipped with the following communication possibilities: Exoline and Modbus via RS-485, a built-in WEB server via TCP/IP and BACnet/IP.
