With an opening force of up to 800 newtons, the Folding arm² door opener PA-KL²-T-80 door opener is just right for the doors of Europe's largest central cooling facility. In Heidelberg, this cooling facility now supplies an entire university campus with cool air.

Franzen Feuerschutztüren installed more than three-metre high and almost two-metre wide gate panels. In the event of a fire, the gate, which is about four meters wide in total, must open automatically and reliably so that enough fresh air flows into the building for smoke extraction. With the Folding arm² door opener PA-KL²-T-80, this can be done in less than 60 seconds - a unique solution on the market.

The gate panels, each weighing 350 kilograms, are equipped with their own overhead door closers. When triggered, the two Folding arm² door opener PA-KL²-T-80 are controlled via an Compact Control Unit SHEV 6 in combination with a latching circuit.

Fire protection and security doors are the specialty of the Franzen Feuerschutztüren company. Their motto "Where others stop, we start!" is visible in this project. We are proud to have a strong product in our portfolio for a project like this with our Folding arm² door opener PA-KL²-T-80.
