Select and configure your Topvex AHU with just four simple commands, without leaving your CAD software! Our plugin for Topvex can be downloaded and used directly in Revit, AutoCAD and MagiCAD. It goes without saying that the plugin is free to use.
Wide range of sizes and airflows
The range comprises two types of Topvex standardised air handling units: Rotary and Counterflow, with side and top connected options. Plus a special outdoor version.
Heating and cooling coils
Topvex offers various heating and cooling coils, with optional 2- or 3-way valves for water-borne systems. The Systemair configurator calculates the Kvs value for the appropriate valve and you can find information about connection size in the printout. Select the corresponding valve variant from the accessories. If the water valve's size differs from the coil's, use a transition coupling during assembly.

Check out our smart Fusion solutions
Systemair Fusion solutions combine ventilation systems, with traditional cooling and heating systems into one optimised package, linked by smart communication. Bringing preconditioned air into the premises, they provide the high quality indoor climate you’re looking for.
What makes these solutions smart?
The Access control system in the AHU optimises the temperature in the refrigerant/chilled water system, keeping the running time of the compressor to a minimum. This ensures highest energy efficiency whenever the system is operating. That’s really smart!
