Allendorf, June 18, 2025 – The new Vitoair CT ventilation system stands out due to its space-saving design and exceptionally quiet operation. It impresses with its flexible installation options, user-friendly control, and high efficiency. Thanks to its cubic, timeless design in Vitopearl optics, it can also be visibly placed in living rooms, offices, and medical practices. With performance sizes of 300, 450, and 600 m³/h, it can ventilate rooms from 280 to 750 m². Viessmann Climate Solutions is part of Carrier Global Corporation (NYSE: CARR), global leader in intelligent climate and energy solutions.
Seamless Integration with Viessmann One Base
Vitoair CT is equipped with the Viessmann One Base platform. This allows for seamless integration into an energy system with a Vitocal heat pump, a Vitovolt photovoltaic (PV) system, and the Vitocharge VX3 energy storage system at any time. In this combination, self-generated electricity is used to operate both the Vitoair and Vitocal systems.
Comfort through Heat and Moisture Recovery
Vitoair CT is optionally available with a standard or enthalpy heat exchanger. The latter not only recovers heat but also regulates the exchange of indoor air and humidity. This prevents rooms from drying out during the winter months and creates a healthier indoor climate.
In the summer months and transitional periods, excess moisture from indoor spaces is expelled outside, reducing moisture damage and promoting a healthier indoor climate. When using an enthalpy heat exchanger, a condensate connection is not required. Additionally, during the winter months, the ventilation unit supports the heat pump with its efficient heat recovery.
Easy Installation and Commissioning
The supply and exhaust ducts can be connected to the Vitoair CT on either the left or right side and selected during commissioning. For commissioning, the professional partner uses the ViGuide Mobile App. The components of the Click-and-Go air distribution system are perfectly coordinated. Its flexibility and quick-connect technology greatly simplify assembly.
New Components with High-Quality Design
The uniform look makes the system unmistakable. The new anthracite-colored Vitoair exterior wall cover blends seamlessly into all house facades and outdoor areas. It serves as the compact connection for outdoor and exhaust air and is equipped with a bird protection grid and a drip edge. The new Vitoair supply and exhaust air valves, with covers made of high-pressure laminate in oak and walnut wood optics, fit into any interior with their premium design.
Flexible Silencer Limits Sound Emission
To achieve effective sound emission reduction, even in tight installation situations and especially for flat, wall- or ceiling-mounted ventilation units, a short and compressible flexible silencer is the ideal complement to the existing longer, non-compressible silencers made from aluminum corrugated tubes. In addition to the visible elements, new collection pipe components with a nominal diameter of DN 200 allow for further applications with increased airflow requirements while maintaining consistent airspeed standards – from outdoor and exhaust air ducts to air distribution boxes with Click-and-Go connection plates.
Awarded the iF Design Award 2025
The Vitoair CT has been awarded the IF Design Award 2025 in the categories of Products and Building Technology. With the Vitoair CT, Viessmann, in collaboration with its partners, has developed a ventilation unit that stands out for its simplicity and flexibility in installation, commissioning, and maintenance, as well as its high efficiency and aesthetic design.
Vitoair Planner – Plan and order directly
The Vitoair Planner allows for the quick design of a residential ventilation system. In just a few steps, the building with all its rooms is created, and a ventilation concept according to DIN 1946-6 is developed. Manual entry of volume flows is also possible. The suitable system, including the ventilation unit and duct type, can then be configured. The clear airflow plan allows the professional partner to adjust duct lengths and choose accessories. The automatic pressure loss calculation provides planning security. The detailed project report contains the airflow plan, all necessary information for commissioning, and recommended throttling settings.
Air Purifier Vitopure for healthy Indoor Air
The new portable Vitopure air purifiers meet the growing demand for healthy indoor air. With cleaning capacities of 250, 350, and 450 m³/h, the devices provide an effective solution to improve air quality in residential spaces. The air purifier is simply connected via a power supply unit and is ready for use immediately. To integrate harmoniously into the home environment, Vitopure air purifiers are available in elegant colors such as Linen White and, starting in 2025, Lava Black.
The Vitopure air purifiers are specifically designed to combat pollen, dust, viruses, and bacteria. More than 99.95% of particles are filtered out of the air by the HEPA/activated carbon filters, effectively stopping their spread. This not only improves air quality but also supports the health of users.
Another benefit of clean air is its positive impact on sleep quality. The activated carbon filter absorbs volatile organic compounds (VOCs) and eliminates unpleasant odors. The air purifier’s operation is indicated by a colored LED ring, which shows the current air quality and signals when a filter replacement is needed.
Vitopure air purifiers can be conveniently controlled via the Viessmann One Base platform, requiring only the ViCare app for operation. Users can manually set fan speeds or use the automatic function, where the device analyzes the room's air quality and adjusts ventilation accordingly. There is also the option to create personalized time profiles. For example, Vitopure can be set to run on a minimum or maximum level for a specific period, such as in the evening before going to bed or for a quick air purification before returning home.
