Auto hydraulic Door closure is a mechanical device that closes a door. After someone opens it, or after it was automatically opened. Door closers are required for Fire-Rated doors, which need to remain closed. To help prevent the spread of fire and smoke.
Door closers have internal springs & hydraulic oil with cylinders and have valves that adjust the speed of the door closing and latching.
To secure the function of any security door, it’s critical that an automatic closing device such as an auto hydraulic door closer is in place.
Door closers are an integral part of many commercial as well as semi-commercial door sets. Door closers maintain the integrity of fire doors along exit routes in buildings used by the general public.
The self-closing function offered by door closers also provides an important level of security for external doors. Preventing them from slamming, staying open unintentionally. Or blowing open in the wind.
