VEX4000 is a range for many ventilation forms and can be combined and configured for any need. Units in series cover a capacity from 1050 to 36,000 m³/h.


Module for VEX4050-4100 with counterflow heat exchanger. No odour and moisture transfer combined with high temperature efficiency.

With the rotating heat exchanger a temperature efficiency of up to 90% can be achieved. Furthermore humidity from exhaust can be transferred to supply air

The crossflow exchanger is suitable for kitchen or process ventilation, as the airflows are completely separated, which avoids transfer of contaminated air

The combined fan and filter module contains plenum fans with total efficiencies up to 70% as well as pre- and main filters in different classes

Integrated reversible heat pump for VEX4000, available with R454B, which reduces climate impact by 78%. Ventilation, heating and cooling in one AHU.

Water coils for heating or cooling the supply air after the heat exchanger.

Electrical coils for heating the supply air after the heat exchanger.

Heating coil for heat recovery from refrigeration units (Store solution)

DX-coils are ideal cooling solution for airhandling units or external DX units, as they are filled with cooling refrigerant in order to be used as cooling coil.

Complete integrated DX cooling system with cooling coil in supply air and coil for excess heat dissipation in exhaust air.

Recirculation can be selected where a mix/reuse of extract air is present and in this way save energy.

The empty section is a module to complement the other modules - for support, extension, reserving space for future functions, and as a safeguard

The integrated acoustic damper module offers great flexibility with many placement options in the unit. The acoustic baffles can be easily removed and cleaned.
