Door Closers Door Closer is a universal mechanism that provides smooth and quiet closing of doors of different types. IDT Energy has much to offer in this field. Today's closers can be installed on the input and internal doors, glass and wood, single, double, plastic and metal doors, as well as the doors swing open and one-sided type. Despite the fact that the door closers are often not controlled devices, they fail to install on the door, operated by ACS, as they provide a guaranteed smooth operation of the lock and the door closing, and all this affects the efficiency of the control system. The principle of operation is quite simple door closers. Operates conventional hydro-mechanical door closer on the basis of a spring, which is placed in a secure metal case filled with a special oil. In order to ensure smooth operation and a slow closing doors, door closers hydraulic damping principle applies, that is, it converts the torque that is applied to mechanically In order to open the door, at the time of closing. Most often, door closers are fitted with special mechanical clamps, which are derived from a fixed position by means of manual force.
The traditional closers for doors with standard arm for these purposes the locking levers are sometimes substituted for the ordinary system of levers with locks. In this case, you can just set the desired angle of the door opening, which will be operate the device and place the subsequent blocking of the lever, which is valid until such time as it will be unlocked manually. At door closers with slide lever, use spring-loaded stopper that blocks the lever in the guide. When you open the door lever lock is held, which does not allow him to return to the starting position and the door itself securely. In order to close the door to just to put pressure on it to lightly push the lever through the stopper.
