Topvex SC is a series of efficient ventilation units designed for apartment houses, offices, shops, schools, daycares centre or similar premises. The units are especially designed to meet the coming rigid energy requirements with low energy use and high-efficiency heat exchanger.

Topvex SC is transportable thru a 900mm opening, the two smallest sizes (03 and 04) thru an 800mm opening.

The units casing is made up from double-skinned aluzinc sheet metal, AZ 185, with internal mineral sound/thermal insulation. To avoid sharp edges bevelled corners from cast aluminium are used.

Large inspection doors and removable main components facilitate inspection and maintenance.

Supply and extract air filter are mounted in guide rails with quick release system and are fitted with sealing stripes to provide optimal sealing against the filter.

The separate electrical cabinet with all cable connections collected at one place facilitates commissioning and service.

To simplify the installation and commissioning of the unit control system are included and pre-configured.

Topvex SC has a user friendly control system. With clear text (21 languages eligible) and a logical menu structure it is quick to learn. A startup wizard secures that necessary settings will not be forgotten.

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

Topvex SC 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.

E-tool configuration tool.

E tool© is a PC-based configuration software with graphical user interface. The program gives you an excellent overview of the Corrigo E settings. Using E tool© , all settings can be made on the computer and downloaded into the controller. An infinite number of configurations can be stored in the computer memory for later use.

E tool© can be downloaded free of charge
