The hydraulic door closer, the arm that automatically closes the door after it's opened, isn't just a convenience: in certain uses it's a regulatory requirement that ensures the door fulfils its protective function.
When it's mandatory
It is mandatory on fire doors (fire protection in escape corridors, plant rooms, garages), which must stay closed to do their job unless they are connected to a detection system that releases them in the event of an alarm. It is also commonly required on communal entrance doors to guarantee they are always closed after someone passes through.
Force according to door size
Door closers are classified by a force number (EN 1–7 under European standards), which must be selected according to the width and weight of the leaf: a light interior access door needs less force than a heavy, large-format fire door. Fitting a closer with insufficient force means the door doesn't close completely, defeating its protective function.
Closing speed adjustment
As well as force, a good door closer lets you adjust the closing speed and the final latching hit, avoiding both the door being left ajar (defeating its purpose) and slamming shut (a risk to people passing through).
