Zehnder Comfosystem – Fresh Air for the Home and Office


Download a Brochure

A constant supply of fresh air in the indoor spaces in which we spend more than 70% of our time is vital to our health. Zehnder Comfosystems comfort ventilation systems provide an assurance that equal amounts of used and fresh air will be exchanged. The Zehnder ComfoBox compact energy station for heating, cooling, ventilation and hot water production represents the ultimate configuration.

The ideal solution for buildings in which the windows often remain closed due to noise or dust particles – and a necessity caused by the increasingly air-tight design of modern buildings. Zehnder Comfosystems promotes a sense of well-being among the residents and helps retain the value of the property. And by means of heat recovery from the extract air, the system provides not only good quality air, but also pre-cooled or pre-heated air, depending on the season.

Zehnder products and systems can provide you with ideal solutions for a comfortable, healthy
and energy-efficient indoor climate.

Benefits of a Zehnder Comfosystem


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.

Energy Savings


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
