Door closer is a hydraulic device that installed above the door, the door can be automatically closed after opening the door by the function of the release of compression. The advantage of door closers is not only to close the door automatically, but also to protect the door (more smooth closure). And door closers have become an important part of modern intelligent building management,especially using for commercial and public buildings, to perevent the spread of the fire and keep the ventilation in the building.

We need to consider the followig factors when choosing the door closer: 

1. The width/weight of the door

The width of the door is the most important factor in choosing the door closer model.And usually the weight of the door is small, choose the model with less power, and vice versa.

2. The frequency of opening the door

This factor closely related to product quality. For frequently used occasions, the sealing performance of the product should be good and the service life must be long.

3. Operating environment

There will be special requirements for door closers in some special occasions or regions. Fire control requires higher grade about anti-fire function of doore closers. In cold regions, there will be anti-freezing requirements and the door closers will use noncongealable oil.

4. Whether there is an automatic door stop function after opening the door, 90° stop function is available.

In breif, we need to know more information before we buy products.Na matter the function, price, we also need to know about the guarantee and after-sale service.
