Fresh air supports health and well-being, which are undoubtedly among the most important needs. How to ensure them in rooms where we spend so much time due to the season and the threat of coronavirus . Zehnder's energy-saving ventilation is an ideal solution for a healthy interior climate, and is so innovative and modern that it increases the value of the property. Trouble-free installation and consistent, comprehensive solutions are important features for the installer.
Zehnder ComfoAir 70 is a decentralized ventilation device with heat and moisture recovery that supplies fresh air to an apartment or individual rooms. Zehnder Comfo-Spot 50 will also work perfectly in these conditions, as it pumps up to 55 m3/h of air while operating extremely quietly. If we are considering a larger number of rooms or a house, a comprehensive solution with a ventilation unit and an air distribution system will be necessary.

Enthalpy exchanger – heat and humidity regulation
In Zehnder ventilation systems, a cross-counterflow ERV (enthalpic) exchanger can be used. It's really worth it, because it allows the transfer of heat energy and moisture between two air streams. In winter, it will allow for the recovery of up to 70% of moisture from the exhaust air, which increases the comfort in living rooms, resulting in a real increase in humidity in rooms by approximately 10%. In the summer, we prefer to reduce the humidity in rooms, which allows moisture to exchange from the supply air to the exhaust air. The Zehnder ERV exchanger is made of a material that is resistant to settling and penetration of bacteria and fungi, impermeable to odors, and can be cleaned with water.
Air distribution – a hidden part of the system
Fresh air must reach every room. For its distribution, we can use a system with round or flat profile channels, which will allow for flexible adaptation to any building conditions. You can choose the optimal variant or combine both where advantageous and install them easily. Zehnder OnFloor are flattened, oval channels that can be placed, for example, in the insulating layer of the floor. Zehnder InFloor are circular channels that can be hidden in suspended ceilings or placed directly in concrete. Their advantage, especially for the future user, is a simple and hassle-free way of cleaning. Zehnder offers its own set, which is already used by many contractors, e.g. during periodic service inspections.

The most important element of the system – the Zehnder ComfoAir Q ventilation unit
Creating a ventilation system should start with an air handling unit, and it will be useful to be able to select three air handling units from the Zehnder ComfoAir Q series for specific building conditions with different performance. For use in apartments, single-family houses, as well as offices and commercial buildings. Plus, they deliver the highest standards of energy efficiency and design combined with ease of use. Energy consumption can be reduced by lower fan power demand by optimizing the use of the AHU interior and the air flow in the exchanger.
What should also be emphasized is the contractor-friendly and trouble-free installation, the intuitive procedure for the first start-up of Zehnder ComfoAir Q and the unique possibility of converting the version from left to right. The interesting design of the housing is combined with ease of use. The display educates the user about energy consumption, comfort and environmental impact through important operational data. The modulated pre-heater optimizes the operation of the device in winter. In turn, the modulated bypass controls the air volume through an adaptive comfort temperature profile, taking into account people's different temperature sensations. These numerous advantages have earned Zehnder ComfoAir Q many awards at home and abroad. In addition to the technical parameters, users will appreciate the quiet operation enabled by the refined design and a special cover that optimizes the air flow to the fan. What is very important is the fact that original Zehnder filters will retain even fine dust, in accordance with the ISO 16890 standard. Every person inhales on average 15 kg of air a day, and this way even the smallest, harmful particles reach the lungs and circulatory system. They can not only cause sleep disturbances, worsen well-being or concentration, but also increase the risk of allergies, asthma and many other diseases. Dust, pollen and soot particles that enter through open windows are one of the main sources of fine dust indoors. Zehnder provides an extended 5-year warranty on the Zehnder ventilation system, which means it is durable and able to withstand any stress.
