Fresh air promotes well-being and a healthy lifestyle. Poor indoor air quality can lead to a rise in asthma and allergic symptoms due to the increased concentration of allergens such as dust mites, VOCs, pollen, and mold. With optional fine filters which capture fine dust and pollen, even allergy sufferers can breathe easily.
Zehnder Comfosystems products use recovered and renewable energy sources to heat and ventilate our increasingly airtight properties in an energy efficient and environmentally friendly manner. Whole house heat recovery ventilation technology can recover up to 90% of the heat and contribute to an energy savings of up to 50%.
On average, we spend approximately 70% of our time inside, therefore the provision of a comfortable environment is very important to both our health and our sense of well-being. Zehnder Comfosystems products can offer:
- Good air quality through continuous extraction of moist, stale air from bathrooms and kitchens and a continuous supply of clean, tempered air to habitable rooms. Low-velocity air supply ensures that fresh, clean air does not create drafts around the home.
Retention of value
The installation of a Zehnder Comfosystems product offers a tangible investment in the future value of your home. Our products will help prevent degradation of the fabric of the building from mold and mildew formation as well as reducing heating and ventilation costs. Our forward-thinking technologies will ensure that the property is upgraded to tomorrow’s standards, today.
- Protection against mildew
- Protection of the building against moisture damage caused by a lack of ventilation
The Zehnder Comfosystems ventilation system provides a long-term solution for the hygienic exchange of air. Thanks to optional fine filters, which capture fine dust and pollen, even allergy sufferers can breathe easily. Controlled ventilation significantly improves the air quality in your home. Zehnder ventilation units with optional pollen filters effectively keep out dust, pollutants, pollen, and insects. The Zehnder ComfoFresh air distribution system transports fresh air to every room in the building. At the same time, humid, used or polluted air and odors are effectively removed.
- Dust, pollutants, pollen, and insects filtered out of outside air
- Humid or polluted air and odors automatically exchanged for fresh air
Because Zehnder design and manufacture all the elements of their systems, components are designed to fit together. This integrated functionality allows for a more rapid system installation saving both time and money for both the installer and the end user.
- Coordinated system components
- Simple, fast and economical installation
Cross-flow, counter-current heat exchangers are standard equipment for Zehnder ventilation systems. They are therefore capable of transferring the heat energy of the used air to the fresh air. This heat transfer takes place through thin plastic plates according to the counter-current principle. The heat recovery level is approx. 90%, which saves up to 50% of the heating costs.
The relative humidity in the building is optimized by plate heat exchangers, which is ideal when the air is dry in winter. The water vapor from the humid exhaust air “condenses” and is taken up by a membrane. The recovered humidity and heat are transferred to the fresh air without any transfer of smells or microbes.
Most Zehnder ventilation systems have a 100% summer bypass. It moves the exhaust air past the heat exchanger and thus prevents the supply air, which in summer is cooled down by the earth heat exchanger, from being re-heated by the warm exhaust air. This function can also be used during cool summer nights.
