Sustainable indoor climate with new heat pump solution


VEX4000 with reversible heat pump, ventilation, heating and cooling in a single air handling unit!


Sustainable indoor climate with new heat pump solution

The simple, reliable and energy-efficient solution for the VEX4000 modular unit.

The ambitious climate targets for the reduction of CO2 emissions require new solutions – one of those is a heat pump, which is an energy-efficient and sustainable solution combined with ventilation. 

The requirements for energy efficiency and low energy consumption for ventilation solutions have generated a lot of focus on combining heat recovery with an integrated heat pump. By combining ventilation, heating and cooling in a single air handling unit, a solution is achieved which is very energy-efficient and much simpler than traditional cooling solutions.

VEX4000RHP, reversible heat pump for VEX4000 - here are the benefits:

  • Low energy consumption
    When you choose VEX4000RHP, you get ventilation, heating and cooling in a single air handling unit
    - simple, reliable and energy-efficient

  • Easy to configure, install and maintain
    This means that with one calculation in EXselectPRO, you get an overview and the technical data for the whole installation, which is contained in a single air handling unit.

  • Very reliable and long lifetime
    Even the installation itself is much more simple, when the entire solution is contained in a single air handling unit. Likewise, maintenance is also much simpler and cheaper.

  • Compact design
    At the same time the solution saves space, since the integrated solution frees up space that would otherwise have been used for the heating and cooling installations.

  • Designed in accordance with VDI6022-1
    The German standard sets stringent requirements for access for effective cleaning, which ensures good hygiene and thus optimal conditions for clean air indoors.

The VEX4000RHP is a very energy-efficient solution, both in winter and summer - see example:

Two variants

We supply the VEX4000 with a reversible heat pump in two variants:


Here the rotary heat exchanger is positioned between the evaporator and the condenser.

With this solution you get:

  • The lowest energy consumption
  • Option for cold recovery




Here the heat exchanger and heat pump are positioned in separate modules. This solution can be chosen with either a rotary heat exchanger or a crossflow heat exchanger.

With this solution you get:

  • A compact solution, i.e. easier on-site transport of modules
  • No need for de-icing
