It is important to choose the right door closer but there is a myriad of choices out there, so actually pinpointing the right one for your situation can be extremely confusing!
In the hope that we can help you to make a reasonably informed choice; we have put together a short guide on the key features that must be taken into consideration.
Is it an internal or an external door? Is it inward or outward opening?
External doors are not fire doors, so you would not need an electromagnetic door closer for these.
For inward and outward opening doors, some closers can be model specific and angle brackets can sometimes be required.
Check the width and height of the frame and door.
These are split into three groups as per the chart below:
|Usage Category||Cycles Per Year|
|Low||Up to 10,000 cycles per year|
|Medium||10,000 - 100,000 cycles per year|
|High||100,000 - 500,000 cycles per year|
You also need to consider the needs of the user; for example; the elderly and less abled people may need delayed close to allow them time to pass through the door.
NB. Hospitals, schools or shopping centres would all be considered to be high volume usage
The larger and heavier the door the more force will be required.
|Power Size||Max Door Weight||Max Door Width|
Often the door closers have adjustable strengths to cater for the size/weight of various types of door.
NB. In a particularly small room, you may require additional force to overcome air pressure. You may also require a higher power size and a closer with latching action for an external door in order to help reduce slamming.
Fire Doors must have a minimum Power Size EN3 to conform to EN1154 standard.
Door closers are an important link in the control of fire and smoke:
This option allows the door to remain open for a specified period of time.
The door should then close at an adjustable speed which allows safe passage for wheelchair users or personnel carrying bulky items.
This feature prevents the door being suddenly thrown open either by people or the wind – this can prevent damage to the door, the frame, door hardware and property.
Having an adjustable closing speed determines how quickly the door closes after being opened - This feature allows a longer closing time to enable the disabled, the elderly or the young to pass by safely
As you can see there are plenty of things to consider when you are choosing which type of door closer is appropriate for your particular and unique situation. If in any doubt as to what you require, give us a call on 01305 257996 or drop us an email - firstname.lastname@example.org.
