Eco-friendly and reliable: Door closer for sliding doors DICTAMAT 50 always closes access doors to bakery immediately and reliably – and without electricity
The powerless, mechanical option eliminates the need for a sliding door operator
For hygienic reasons, the access doors to the bakery must always close immediately after opening to prevent insects and other unwanted environmental influences from getting into the bakery. Until now, this was done using fully automatic sliding door operators. However, their service life came to an end and spare parts were no longer available. A complete new installation would be very expensive. And last but not least: they require high annual maintenance costs!
Mr. Schomaker therefore specifically looked for a mechanical sliding door closer and found what he was looking for at DICTATOR.
The DICTAMAT 50 BK sliding door closer is extremely flexible due to its modular design and can therefore be easily adapted to on-site conditions. The entire rail and door structure could be taken over without modification. The two leaves of the double-leaf doors run synchronously and can therefore be moved with a revolving toothed belt. The closing force is applied by two small spring rope pulleys, and the closing movement is controlled over the entire travel with a radial damper.
Now the doors are opened manually – and close again immediately after each opening. And because the closing speed is adjustable, the closing action is just fast enough to allow the user to step through the door comfortably. Additional safety devices are not required in this case, as the closing force is far below any hazard limit.
