Minimal visual impact
Installation concealed into the door leaf maintains the visual integrity of your doors – out of sight but always at work
The DC850 is a concealed door closer with Cam-Motion® technology and guide rail system that can be used for fire and smoke protection doors (without the addition of the hold-open device). It can be used on single leaf doors 850-1100 mm wide.
It is the perfect solution for balancing the need for easy access and the need for protection. The opening force decreases rapidly thanks to Cam-Motion® technology and ensures that the door opens with less effort, according to barrier-free DIN 18040 and CEN/TR 15894 standards.
It has an adjustable closing force EN 2-4 according to EN 1154. Spring preload adjustment makes the product versatile and suitable for different needs. It can be equipped with a standard guide rail or a smaller 20 mm guide rail, to ensure great compatibility with different mounting options.
Closing speed and final latch are adjustable via independent, thermodynamic upper control valves to ensure consistent performance under different temperature conditions.
