increasing popularity of door closers due to the following positive qualities:
- protection against external noise and the negative environmental impact;
- energy savings due to thermal insulation and the absence of drafts;
- safety of use.

latching device and how it works
Closer consists of a link arm and the body with the mechanism responsible for the correct closing of the door.The mechanism consists of a powerful spring, which is compressed by
Choice door closer
main parameter that is selected closer to the door - this is his power.Therefore, in the first place, it is necessary to take into account the size and weight of the door, to set them closer able to work correctly.Accordingly, the heavier and heavier the door, the more power is needed to close it.In some cases, even two closers are used, allowing to use less power to close the door.
Door closers are divided into 3 types according to the method of installation:
- the bottom (floor);
- hidden (RAMS).
most common because of its simplicity, is the first way - to set the closer to the top of the door.Such coils can be installed on almost any door.
efforts to develop closer, normalized European standards.The higher the class standard EN1154 - the more power the device.For example, the closer to the massive armored door need top class EN7, but for lighter models door closers can be set with the lower class.For normal input and interior doors are usually used closers class 3-5.
But it should be noted that in choosing the closer you need to focus on the highest settings the door or external factors.So, if the door is exposed to side winds, has a height of over 2.5 m and non-standard sizes, we should choose a closer vyshe.Esli class size and weight of the door correspond to two different classes of closers, it also should be selected for the highest grade of safety andhence, durability.
impossible to approach the choice of the closer only with the expectation that more powerful than he, so it will work better and last longer.This is wrong on all counts.For example, a powerful set closer to the plastic door will create an additional burden on the door hinge, causing premature wear and failure.Moreover, these doors will be very difficult to open, chtosozdast additional inconvenience.It is equally important when choosing a door closer to pay attention to its hardiness.There are models that can operate correctly under extreme temperatures dipping to -45 degrees or rises to 70 degrees.
Install door closer on the door
in a box with a door closer can be found:
- himself closer;
- adjustable link arm;
- mounting hardware;
- scheme for the installation.
Install door closer can be made both on the door leaf or on the box.Also, depending on the purpose of the door, there are two types of mounting door closer - internal and external.Typically, the most common way to install door closers for exterior doors is an internal installation, with fixing the closer to the doorway.This is due to the fact that not all devices are designed for operation in winter.
Most manufacturers mans circuit closers mounted life-size.It is very convenient.In this case, setting the closer to the metal door pass without errors.It is necessary to glue the tape circuit on the door, carry out the necessary markings and drill holes in the designated areas of the required diameter.Then we fix the body, guided by the same wiring diagram, paying attention to the particular installation.For example, door closers dorma mounted so that the adjusting screws located at the side of the door hinge.
After fixing mechanism closers need to start assembling the thrust lever.It consists of two halves, connected by threads.The length of the lever can be adjusted in length.Because of this door opening angle, exhibiting equal to 90 degrees.If the markings and the installation of the door closer was conducted in accordance with the wiring diagram, it should work the first time.
Setting door closers
To properly adjust the closer job should deal with adjusting screws at the machine frame.If closers dorma regulated end of the body, the door closers are geze adjusting screws under the decorative cover.As a rule, they are numbered on the housing 1 and 2. The first screw changes the angle of the door opening, which can be 180 degrees, and the second - the speed of its closure.
first regulated by the opening angle of the door leaf.To do this, screw put the required value of 90 or 180 degrees, and then proceed to a change in the acceleration of the door closing bolt 2. After opening the door on the right angle of release and rotation of the screw 2 achieve the smooth running of the door in the last 7-15 degrees and self latching action.Adjust, you should not exercise more diligence, after turning a quarter turn of the screw the door will be closed with a marked slowdown.
correct setting door closer with timely and periodic adjustment allows to use it for a long time.But often careless tenants porch propped door entrance for ventilation or the removal of things.This creates an additional burden on the piston seals and leads to the extrusion of oil from the housing.As a result of these actions the internal mechanism may be damaged, and the repair of door closers will not be able to return it to its original operating state.Out of the situation will be one - to buy a new door closer.

- Korea - KDC (for the manufacture of door closers companies used German components and anticorrosion materials ensure a long service life);
- Taiwan - Oubao (line closers for light doors acclaimed by many customers, it is lightweight, durable and inexpensive models);
- Finland - Abloy (the most convenient system control terminal unit through independent valves, which are responsible for the smooth movement of the door and latching action);
- Serbia - Diplomat (very popular two-speed model).
