The resultant in the force parallelogram is oriented inwards. Therefore, external air enters and cools the indoor rooms.
Discharge is against the wind direction
The resultant in the force parallelogram is oriented vertically. Therefore, external air does not reach the inside and warm internal air does not reach the outside. The temperature level remains the same.
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.
