THERMOVENT air curtains for service doors and factory gates
FRIGOVENT air curtains for cold store doors and freezer rooms

How is the optimal amount of air controlled?

In the corporate sign on the right cap of the plant is the plug adapter for the hand switch or for the proximity switch and the rotary knob to control the air volume and air velocity.


The knob is secured on some models, so you can adjust it using only a screwdriver.

By turning the knob you can adjust the air speed continuously.

The amount of air flows at a speed of about


15 m / sec from the nozzle.

The speed slows down the more the air flow approaches the ground.

If the air speed is too low, the air flow does not reach the ground.

Air flow of an air curtain system


If the air speed is too high, it collides heavily on the ground, which leads to disturbing turbu-

The air flow must be regulated so that it extends to the ground.

When air curtain is switched off, the wind turbine rotates.

At operating doors it is powered by cold airflowing into.

If you turn on the system and increase the air speed, you will see that the wind turbine will slow down and eventually stop.

If the wind turbine stands, it is guaranteed that it is also in the weakest area of the air flow - namely, on the ground - there will be no more air exchange.
