Indoor Air Quality at its best

The DXA 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. 

An outstanding energy performance throughout the year

By combining the benefits of a full demand control of airflows and heat recovery, the DXA offers the best energy performance solution. With an 93% heat exchanger efficiency and a reduction by half of the statistical airflows leading to an equivalent saving on the associated thermal allows to reach about 95% energy savings when compared with a mechanical exhaust ventilation system at constant airflow, with the same indoor air quality.

Easy to install

DXA has been designed in such a way that only one person is required to install it. Handles on the side of the unit are specifically designed in order to better grasp it. In addition, the appliance has a very high resistance to weight ratio. Weighting only 23 kg, DXA requires few wall clampings.

Easy to maintain and set up

Three 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. 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.

Sustainability

The main material used to produce the DXA, the EPP (Expanded Polypropylene), is a ¨green¨ material, environmentally friendly, 100% recyclable. It does not include any VOC (volatile organic compound), CFC (chlorofluorocarbon) or other compounds known to be particularly harmful to the environment.
