How to choose the right door closer?

Door closer is a device that provides automatic closing flaps.

Everything happens silently and smoothly. There are many variations of such mechanisms.

But to choose the right door closer, you need to know the technical characteristics of the devices offered on the market today, and be able to choose the best option for a particular door system.

GOST 5091 introduces a variety of devices. The main criterion, which is based on the characteristics of closers - forces applied when the door is closed.

According to the standard 5091 all door closers conventionally divided into 7 classes:

  • EN1. Mounted on the sash width of 75 cm and weight 20 kg.
  • EN2. Apparatus is ideal for web width of 85 cm and weight 40 kg.
  • EN3. Devices mounted on a flap whose width is 95 cm, and weight - 60 kg.
  • EN4. The apparatus used for a leaf of a width of 110 cm and weighing 80 kg.
  • EN5. Install such devices for the sash width of 125 cm and weighing up to 100 kg.
  • EN6. Devices of this class are fitted with doors 140 cm wide and weighing up to 120 kg.
  • EN7. These mechanisms are ideal for webs 160 cm wide, and weighing up to 160 kg.

GOST 5091 forces exerted when closing the door leaf, measured in Nm (newton). Certificate issued to the manufacturer of the products contain indicators Nm. In this case produced as a one-class model (specifically contains Nm), and adjustable versions, where possible setting the effort for opening structure.

In addition, the standard 5091 is another feature, which pay attention to when choosing a door mechanism - the transfer of torque.

What is in door closer

Given this criterion distinguishes between the following devices (certificate contains this feature article):

The peculiarity of this door mechanism consists in the fact that it consists of two interconnected axes which when opening the door leaf bent at the knee. Such a device is robust, and the duration of the maintenance period. However, he has a drawback - poor security mechanism: it often becomes a victim of vandals.

  • Floor.

    This device - ideal for shops, offices and other public places.

  • The mechanism by which the structure is provided a sliding channel.

    The principle of operation of such a door closer: the end of its arm moves along a special channel.

  • RAMS.

    It works just like the outdoor unit. The difference between them lies only in the fact that this device is fixed to the door frame.

  • When choosing a door closer in the first place take into account the weight and width of the door: the wider and heavier fabric, the higher class should be installed device (GOST 5091 reflect these nuances). However, if the leaf width of 160 cm Bole, installation of this device is not recommended.

    In addition, if you choose this mechanism pay attention to the closing speed of the door system. Here, a clear assessment criteria of this index does not. So, for example, for fire door systems choose devices with a high closing speed, and for home use (especially if the house there are small children or elderly people) make a choice in favor of a slow closing. For public places better to buy a device with braking function open (it protects the leaf from hitting the wall).

    In medical institutions is better to install the device with a latching function in the open position. Product certificate introduces the potential buyer with certain additional features, which has offered goods.

    And yet, a certificate for the products - it is a guarantee that the purchased goods are of high quality. Therefore, the choice of the device is recommended to ask about the presence of the certificate. The only way to be sure that the selected device will last for many years regularly.
