What issues should be considered when choosing a door closer?
Before choosing a door closer, you should consider door weight, door width, door opening frequency, usage requirements, usage environment, etc.
Door weight and door width are the prerequisites for choosing the door closer model. Generally, the door weight is small and the force is small. First, it feels very easy to open the door, and the installation on the door is also harmonious and beautiful; second, small products are generally more economical. vice versa.
The frequency of door opening is closely related to the quality requirements of the product.
First, the door closer is required to have better sealing performance and no oil leakage. The key is the technology and material of the dynamic seal; the second is to require the door closer to have a long service life, so as to ensure long-term and normal use after installation, reduce maintenance, and reduce maintenance costs.

It can be installed on different doors with a wide range of door weights and door widths, and can be adjusted steplessly in places where the door closing resistance is largely due to environmental reasons to obtain satisfactory closing force. changing place.
5). Use environment: fire protection requirements (fire protection requirements), antifreeze requirements (places with minus 35 degrees in northern winter).
