While most ventilation systems on the market offer constant or globally controlled airflows, the DX Excellence MVHR stands out as one of the first residential heat recovery ventilation to automatically adjust ventilation according to the specific needs of homes, thanks to room-by-room regulation. DX Excellence is dedicated to residential applications and can be either installed in false ceiling, thanks to a small thickness, or in kitchen cupboard, due to optimized dimensions.
By combining the benefits of demand controlled airflows and heat recovery, which are the pillars of the DynamiX® technology, the DX Excellence, delivers outstanding energy performance. Modulation enables a significant reduction in average airflows while providing excellent air quality, with heat losses produced by ventilation lowered by half on average in comparison with a constant airflow ventilation. The heat exchanger operates with an efficiency of about 82% recovery. These features enable substantial energy savings.
DynamiX® Technology: ensures a silent system and optimal indoor air quality through room-by-room demand control.
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 demand control of airflows and heat recovery.
Enjoy a real interactive experience
The DX Excellence has been completely designed to give the occupant of the accommodation a central position regarding the management of the indoor air quality. The DX Excellence can communicate with the user and transmit to them in real time plenty of information such as the clogging rate for each filter, the indoor air quality and the temperature of each room. Via his smartphone, the occupant can fully configure the DX Excellence to achieve optimal comfort.
The DX Excellence is available in ceiling version (DXR). The DX HUB range is available in three versions offering different outlet diameters, a variable number of outlet and acoustic or non-acoustic versions. Consequently, the DX System in its Excellence version adapts to different configurations and to the constraints of each project for optimal and easy installation.
Once installed, the DX Excellence is immediately functional. The level of maintenance required is very low. Indeed, thanks to the demand-controlled ventilation and a very wide filter surface, the DX Excellence filters’ lifetime is doubled compared to traditional mechanical ventilation with heat recovery. Thanks to its notification system and a clogging detection embedded for each filter, enjoy your home peacefully. The DX Excellence will automatically notify you as soon as filters need to be replaced.
High quality manufacture
Because quality is our priority, DX Excellence 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 Excellence is guaranteed as a very robust and reliable product throughout its lifetime.

How does room-by-room regulation work ?
Principle of operation
The DX System is comprised of a main unit DXR (ceiling-mounted) connected to exhaust and supply ductworks. The counter-flow heat exchanger, integrated into the main unit, ensures the recovery and transfer of most of the energy from the exhaust air to the supply air, thus limiting the energy required to heat the fresh air.
Airflows are automatically controlled according to the needs of each dwelling’s room. Outdoor filtered air is supplied (3) in the bedrooms and in the living room. Stale air is extracted (6 , 7) from the kitchen, bathroom and WC.
The supply airflows to all main rooms are regulated based on the inputs from one or many CO2 sensors or occupancy sensors (5) . On the exhaust (6) side, the airflow is adjusted, according to parameters read by various sensors (BXC²): humidity in the kitchen and bathroom), and occupancy sensors in WC.
The total supply and exhaust airflows are balanced thanks to an exhaust-controlled compensation valve (8) , installed in the bathroom or in the kitchen (7) . An additional compensation valve, integrated in the DX Hub (2) , adjusts supply compensation airflow, supplying preheated (4) fresh air in the living room, in the kitchen or in a corridor.
The heat recovery ventilation DX Reference system is the ideal solution for optimum air quality throughout the year while minimizing the energy consumed. This system supply healthy and preheated outdoor air into living areas.
Through the DX Evolution, a completely new range of heat recovery ventilation system has been designed by Aereco to offer you the maximal flexibility in your choice for the adequate ventilation solution. The DX Evolution product range is intended for a residential application and can be either installed in false ceiling, thanks to a small thickness, or in kitchen cupboard, due to optimized dimensions.
