Constant pressure fitted to demand controlled exhaust units.

DynamiX® Technology: ensures a silent system and optimal indoor air quality.

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

Easy installation in ceiling spaces thanks to its small thickness (only 26 cm).

Easy maintenance of the filters through compact bottom trapdoors.

High-quality manufacture with main parts, made of metal.


Indoor Air Quality at its best

The DXR enhances indoor comfort by providing healthy air, at a milder temperature, preheated by the integrated heat exchanger. To feel good at home, the DynamiX® Technology, available on "Excellence" version, adapts, at any time, both supply and exhaust airflows to the occupants needs in every room through accurate sensors (CO2 or presence). The DynamiX® Technology is a smart demand control strategy specific to the DX System which follows two main purposes: to reduce inherent noise from the heat recovery system while guaranteeing the best Indoor Air Quality.

Low maintenance

By reducing the average airflows with an equivalent indoor air quality and thanks to a large surface of filtration, filter durability is doubled compared to traditional heat recovery systems.

Low energy consumption

In addition to significant energy savings on heat losses thanks to the DynamiX® Technology, the DXR limits primary energy consumption by reducing fan power. Combining a smart and accurate demand control strategy and high quality fans, the DXR offers a very good energy performance, up to 50% reduction of electrical consumption in comparison with standard heat recovery units.

Easy to set up

A color LCD touch screen allows the occupant to view system parameters, to diagnose operation, to 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-end quality with harmonious design

DXR's galvanized steel protective body and numerous metal parts (heat exchanger, motor support, etc.) give it an optimal robustness for all its different phases of life, from the installation to the maintenance of the product. Coated in a creamy white color, the DXR is distinguished from the usual technical elements.
