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.

Topvex FR is designed for meeting the coming energy demands with high heat recovery efficiency and low energy use. To guarantee the high heat recovery efficiency the exchanger is designed for low air speed and by that also a low pressure drop. The supply and extract airFilter are designed to have a low pressure drop, without compromising with the filtration efficiency. A low internal pressure drop is essential to keep the energy use down Topvex FR features Plug fans with EC technology to ensure high efficiency. The EC-motors has when speed-controlled, 15-20% lower energy consumption compared to a standard frequency controlled asynchrony motor.

Constant air volume control is standard and Variable air volume control is available as an accessory.

Topvex is delivered with the new Access control system. The system includes NaviPad control panel, featuring an easy-to-use intuitive HTML5 user interface.

The protection class of the NaviPad control panel is IP54 and 0-50°C; permitted temperature. The enclosure is not UV resistant and the NaviPad is not for outdoor mounting. Communication between the panel and the controller in the cabinet is possible with up to 100 meters of cable.

The NaviPad is connected via 3 meters flat cable. It is mounted on the Topvex unit or on the wall, easy to detach for handheld use.

Relevant operating data and settings are available in real time and can be changed with a few clicks.

Access control has built-in energy saving features like free cooling, cooling recovery, season related temperatures and airflow control.

Possibility to edit names for the unit, the alarms and control components gives the user options to adapt to different installations needs.

With the system overview dashboard it is possible to monitor several air handling units within a local network.

Standard communication possibilities are: Modbus RTU via RS-485 & TCP/IP & BACnet via IP.

The separate electrical cabinet with all cable connections collected at one place facilitates commissioning and service. The functions and functionality in Topvex FR guarantee that all features are provided to give you the best indoor environment with the highest comfort to the lowest operating costs.
