Decentralised school ventilation

The WiVent-B decentralised ventilation unit provides pure air in classrooms and conference rooms – almost as if you were outdoors. It doesn't matter at all if it is a new building or a renovated building. Sensors detect both the outdoor and indoor temperature and the CO2 content in the indoor air, regulating the ventilation system in accordance with the requirement. However, the teacher can also set the temperature and ventilation level of the ventilation units individually via various control units.

Decentralised ventilation in schools, benefits from many advantages.

Can the decentralised ventilation be adapted automatically to the temporal use of the classrooms?

The control of the decentralised ventilation can be adapted to the individual use of the classrooms  to the day or the exact minute. For this purpose, there are six different operating modes which can be allocated to up to 12 time windows. These can also be configured for times when the school is not in use, for example during holidays.

Which requirements should be fulfilled by the school building or classrooms?

The classrooms or teachers' rooms being ventilated should have a connection to a facade so that outdoor air and exit air can be directed through it. For optimum room ventilation there should be sufficient room for setting up and the depth of the room should not exceed 8 m. 

Can the windows of the classroom still be used for ventilation?

The room can be ventilated by using the windows at all times. For this purpose, window contacts can be used to switch off the ventilation unit as soon as the window is opened. As soon as the window is closed again, ventilation starts up again automatically.

Does a room control unit have to be installed in every classroom?

This is not absolutely necessary but recommended, as this means that the individual needs of the students and teachers can be addressed locally. Moreover, there is of course the option of carrying out these adjustments by using the web interface.  

How much work is required for servicing of the ventilation unit?

Due to the modular construction and the intelligent design individual modules can be removed and serviced easily and without the need for tools. The hygienic design and smooth surfaces minimize contamination and allow an easy cleaning.

Low CO2 concentration for full learning success

Fresh air with a low CO2 concentration increases the ability to concentrate. That is why it is particularly important in schools that the students in the classrooms are supplied with sufficient fresh air. The WiVent-B school ventilation system provides the pupils and teachers in the classroom with a stable room climate with good air quality, even with varying occupancy rates. The key: a special reversing flap allows you to switch between low-turbulence displacement air flow and strong-impulse mixed air flow to suit the requirement. The CO2 control of the WiVent-B specifically ensures compliance with the specified limit values.

Displacement air flow

In operation with displacement air flow, the supply air enters the classroom across the entire width of the unit through to the open change-over flap. With a low flow impulse and minimal under temperature, the supply air is distributed over a large area on the floor of the entire room with little turbulence and forms a fresh air lake. At heat sources such as pupils, the air finally rises, thus ensuring optimum air quality.


Mixed air flow

In operation with mixed air flow, the closed change-over flap reduces the outflow cross-section. As a result, the air penetrates far into the classroom with a higher flow momentum. This ensures that the room is flushed more quickly and efficiently. When heating, the ventilation unit replaces the radiator.


Pleasant learning climate


The displacement flow is characterised by a low degree of turbulence and an extremely low impulse. These characteristics guarantee maximum comfort for pupils and teachers. Noteworthy is the high penetration depth into the classroom despite the low impulse.



Even in an equipped and occupied classroom, the goal must be to achieve a very good ventilation result. For ventilation with displacement air flow, the reliable formation of the fresh air lake is considered an important basis. Obstacles such as school satchels cannot prevent a well implemented displacement flow from forming a fresh air lake.

Warmness in winter


Even in winter, the decentralised school ventilation WiVent-B ensures a pleasant learning temperature. In order to bring the supply air into the room during heating, a greater impulse is necessary due to its higher temperature. This is achieved with the help of a special changeover damper. A good flushing of the room is also guaranteed with this type of flow.
