Use and function

Door closers are an essential component of a door system for commercial and residential buildings, especially when it comes to turning a door into a robust protective element in the event of fire. Door closers are designed to return a door to its closed position after being opened. When combined with an automatic locking system, this helps to ensure that the premises remain secure following entry by authorized personnel. In terms of fire protection, the door closer holds the door in place, helping to form a barrier and slow a potential blaze’s progress. Installing a door closer is simple, as all dormakaba products are designed with convenience and rapid implementation in mind.

What are door closers?

A door closer is a mechanical device fitted to a door in order to control the closing process. It consists of a hydraulic mechanism installed directly on the door frame or the door leaf. When the door is opened, the included spring inside the door closer stores essential energy. Afterwards, the energy is released, thereby automatically closing the door. In other words, there is no need to push the door closed manually.

There are various types of door closers, including hold-open and non-hold-open door closers for interior and exterior doors, with the former engaging its hold-open function once the door is opened beyond a certain angle. This is convenient when permitting access by groups, people with disabilities or individuals with mobility issues, or when moving bulky items into or out of a building. In principle, door closers with a hold-open function are not suitable to be installed on fire doors or smoke protection doors – this is because the door needs to be held shut to create a barrier and prevent the spread of fire and smoke. Door closers that are equipped with an electromagnetic hold-open (EMR) as well as an integrated power supply unit and smoke detector are an exception. In the event of fire, these release the hold-open and the door is closed by the door closer.

Overhead door closers are typically found in commercial buildings, e.g. office buildings, while heavy-duty door closers are ideal for industrial premises. Concealed closers help to maintain the streamlined appearance of a building’s main entrance. By choosing a door closer from dormakaba, you can ensure that your building’s doors are secure, reliable and energy-efficient.
