Ecological and reliable: The DICTAMAT 50 door closer for sliding doors closes the door to the bakery always at once and reliably – without needing any current
The mechanic variant needing no electricity outcompetes the sliding door operator
For hygienic reasons the access doors to the bakery always have to close at once to make sure no insects and other undesired environmental influences get access to the bakery. Up to now this ensured fully automatic sliding door operators. However, their operational life came to an end and spare parts were no longer available. Completely new door operators would have been very expensive, not to forget the annual maintenance costs for the installations!
For this reason Mr. Schomaker was deliberately looking for a currentless door closer for the sliding doors and he struck at DICTATOR .
The modular system of the DICTAMAT 50 BK sliding door closer is very flexible and therefore easily adapts to the structural conditions on site. The complete rail and door construction could remain as it was. The two door leafs of the double sliding doors run synchronously and thus can be operated by one revolving toothed belt. Two small spring rope pulleys provide the closing force, the complete closing being controlled by a radial damper.
Now the doors are opened manually – and close immediately after every opening. Thanks to the adjustable closing speed the doors close just as fast that a person can easily pass through. Additional safety equipment is not necessary, because the closing force is far below any hazard limits.
