Thermal situation

In the door region with warm air curtain systems

With warm air curtain systems, in the door region, a quantity of heated air is discharged at a certain angle against the cold air trying to penetrate from the outside. There are two different types of shielding from cold air:

Thermal situation

Standard Air Roll (SLW)

For the standard air roll (SLW), the air intake is within the room and the air discharge is close to the door. The air roll shields the door opening and mixes with any cold air entering the door region. The air roll rotates towards the inside of the room and then back towards the intake grille.

Thermal situation

Reversed air roll (ULW)

For the reversed air roll (ULW), the mixed air intake occurs in the door region. The air discharge is into the room. The air roll protects the door region near the floor from cold air entering. The air roll rotates away from the room. A slight overpressure in the door region results from the external air component of the air mixture drawn in to the unit.

About us

Founded in 1981 in Leichlingen/Rheinland, Germany, today we are one of the leading providers of door air curtains in Europe. Due to constant growth, in 2005 we moved our production location from Leichlingen to the neighbouring town of Langenfeld. This is also the location of our current extended production and administration building, which we moved to in 2010. From here we sell our “Made in Germany” products throughout the world. Securing the future of our company and thus safeguarding local jobs as well is the reason why we have always remained faithful to our Rhine region.
