Layer ventilation from TEKA

The most efficient method of ventilation technology

Thermal air currents in industrial halls

When machines are operated in production halls and workshops whose surfaces are warmer than the surrounding air, upward air currents, also known as thermal currents, are created.

Without adequate room ventilation, these thermal currents create a circulation that causes a large proportion of the rising air masses to be recirculated back into the work area. Removing the thermal currents in the ceiling area is generally not sufficient to prevent this circulation flow, as the thermal currents cause a lack of air in the area near the floor, resulting in a circulation flow in the lower room area. Unsuitable air routing can even favour the recirculation of pollutants, for example if the supply air is introduced into the room from above or from the side. This leads to rising smoke or pollutants being distributed throughout the room right down to the floor ar

Layer ventilation

To prevent backflow, the air rising due to thermal currents must be replaced in the area close to the floor (pressure equalisation). This method of air routing is known as stratified ventilation. Layered ventilation is characterised by the fact that the supply air is introduced in such a way that the thermal currents remain undisturbed and air equalisation takes place in the working area. This requires a low-pulse supply air flow, which can be achieved in various ways depending on the arrangement of the air diffusers:

- Displacement outlets in the floor

- Displacement outlets in the work area

In industry, displacement outlets in the floor are not normally practical. Instead, displacement outlets in the work area near the floor make sense. We, the air purifiers from TEKA, are absolute experts in this type of air purification.

TEKA is well positioned

TEKA offers several types of centralised systems that can be used as the basis for stratified ventilation. Our FilterCubes and ZPFs are particularly suitable. However, as the design always depends on the structural situation, the volume of smoke and the size of the hall, we cannot offer an off-the-shelf solution.
