A door closer is a device that enables a door to close whenever someone opens it or if is automatically opened. These are commonly seen in lots of commercial buildings.
There are three different styles in installing the door closers and they can be concealed in frame and concealed in floor or surface mounted. Door closers that are surface mounted have four different types. These are regular arm, slide track arm, parallel arm and top jamb mounted. Overhead type closers are mostly surface mounted, even though there are a lot of manufacturers that offers concealed models also like Norton 7900 overhead concealed and the Rixson 27 series. These are mounted inside of a pocket of the door frame though sometimes they can also be mounted in the floor under the pivot area directly and are concealed completely. Surface mounted door closer devices are the small boxes attached on the door's top corner. The arms that are jointed are the ones extended from the top level of the box on to the frame where this is bolted in.
Door closers have two distinct kinds: automatic and manual. The ones that we mostly see and are more common are the manual type door closers. There are over 70 percent of commercial buildings located in North America are using manual type of door closer.
How do they work? For manual door closer, either the jamb mounted or the overhead works on the air pressure principle and stored energy. This device is storing the energy that is being generated whenever somebody pushes the door open. After the energy has been generated, it will then use the stored energy to close the door automatically even without someone applying any force to close it. You can control and adjust how much closing speed you want by using hydraulic dampers or spring mechanisms on this device.
Automatic closers on the other hand use electrical power instead of the energy given by man. This kind of door closer is usually more expensive. This most of the time comes with a remote control for the device and a security alarm that you can turn on whenever you need it.
