Easy installation thanks to multiple positioning.

Nearly zero maintenance.

High-quality: many parts in metal. Made in France.

DCV compatible: an intelligency included that optimizes the DCV performance

Very low energy consumption by combining demande control of airflows and heat recovery.

Achieved filtration to prevent from outdoor air particles: optimal and large filter surface design to limit the clogging for maximal life-time.


Indoor Air Quality at its best     

The DX Evolution enhances indoor comfort by providing healthy air, at a milder temperature, preheated by the integrated heat exchanger. Equipped with constant pressure regulation, the DX Evolution fits perfectly with a constant pressure ventilation system. The DynamiX® Technology is a smart demand control strategy specific to the DX System which follows two main purposes: reducing inherent noise from the heat recovery system while guaranteeing the best Indoor Air Quality.

Best energy efficiency 

The DX Evolution optimally uses the exhaust heat to preheat the fresh air and thus offers an energy-efficient solution, whatever the version. Moreover, the demand controlled management enables to decrease significantly the electrical consumption of the system. The best energy-efficiency class A+ is achieved by the DX Evolution.

Easy to maintain and set up         

Filters can be easily replaced without dismounting the unit, by simply removing the trapdoors. Filter durability is doubled compared to traditional heat recovery systems, notably thanks to a very large surface of filtration and demand controlled airflows. Using a smartphone, the occupant can view system parameters, diagnose operation, control setups such as automatic bypass temperature, to boost ventilation or to action a free cooling on demand. It also notifies the occupant when the filters need to be replaced.

High quality manufacture             

Because quality is our priority, DX Evolution components are selected for their reputation and reliability. Thus, by combining French manufacture, solid components and demand-controlled ventilation (which reduces stress on the fans), the DX Evolution is guaranteed as a very robust and reliable product throughout its lifetime.
