Zehnder dual-flow VMC systems: comfosystems and air quality

Since the first oil crisis in 1973, France has implemented a process of steadily tightening its thermal regulations (RT 2005, RT 2012) to achieve positive energy new buildings by 2020. To achieve this goal, the airtightness of these buildings has been reinforced, leading many of us to live in increasingly airtight homes. However, it is vital to ensure indoor air quality and renewal to benefit from a healthy home that offers health, thermal comfort, and acoustics to its occupants.

Since indoor air quality is synonymous with good ventilation, Zehnder Comfosystems' high-efficiency dual-flow CMV systems are the natural choice. They offer an effective solution to meet the needs of home comfort while also making it energy efficient.

Operating principle of Zehnder Comfosystems double flow CMV systems
To maintain healthy air in the home, limit indoor pollution (smoke, odors, etc.) and prevent humidity from building up, it is essential to ventilate.

Zehnder Comfosystems' innovative heat recovery technology makes high-efficiency dual-flow ventilation systems cost-effective in addition to providing comfort. They operate on the following principle: using a heat exchanger, they heat the fresh air entering the home by recovering the heat from the stale air exhausted outside.

They consist of a central unit and an air distribution network which supplies all rooms with fresh air and simultaneously evacuates stale, humid and polluted air, as well as odors.

Advantages of Zehnder Comfosystems dual flow CMV systems

Energy savings
Zehnder Comfosystems' high-efficiency dual-flow ventilation systems control the amount of fresh air supplied to the home and the extraction of polluted air. Beyond air renewal, they improve the home's performance by recovering heat from stale air released outside. This supply of warm air increases the ambient temperature of the home and thus reduces heating requirements.

Health and comfort
An enthalpy heat exchanger, which recovers moisture, prevents the air from being too dry in winter.
By replacing stale air with fresh air, Zehnder Comfosystems ventilation systems eliminate excess humidity and prevent mold, which can be harmful to health.
The materials used for air distribution ducts are guaranteed VOC-free to ensure good air quality over time. Zehnder Comfosystems offers a complete air distribution system ensuring acoustic and thermal comfort.
To ensure the well-being of occupants, the incoming fresh air is filtered and thus freed from pollutants such as pollen, dust and particles that are often allergenic. It is also preheated in winter and cooled in summer.
The quality of the air distribution network is the key element of any ventilation system. The tubes constituting the air distribution network of Zehnder Comfosystems ventilation systems are equipped with a smooth double inner skin, Clinside, which guarantees the cleanliness and cleaning of the ducts at more than 98% and ensures the durability of the system.
. Thanks to cross ventilation, air exchange takes place without drafts or unwanted noise, but with maximum efficiency. The required air volume can be adjusted individually.

Aesthetic
The ventilation and exhaust grilles are elegant and discreet, blending harmoniously into any environment. All models are available for recessed or surface-mounted installation and are made of stainless steel or white lacquer.

A system adapted to every need
To meet all the airflow needs of homes, from studios to large houses, Zehnder Comfosystems has a wide and efficient range of dual-flow CMV systems adapted to each project, some of which are NF certified: Zehnder ComfoAir 200, Zehnder ComfoAir 350, etc.

Zehnder Comfosystems, the assurance of a quality installation
To ensure quality, Zehnder Comfosystems systems are installed by installers trained in the brand's products at its training center, Zehnder Academy in Evry (Essonne), or in the region, directly at the professional customer's premises or in one of the 3 regional training centers. Present throughout France through its technical advisors, Zehnder Comfosystems supports professionals from the beginning to the end of the project and assists them from the installation of ventilation ducts to the commissioning of the system.
