If there is a large flow of people, hundreds to thousands of people enter and leave every day, and the door opening is large, such as shopping malls, airports, etc., it is better to choose a door opener with a good brand to avoid failure of the door opener during the peak period of the flow of people , It brings great inconvenience to customers and affects their own impression. Correspondingly, if the flow of people is not very large, but the door opening requirements are large, such as a car dealer, you must choose a door opener that can bear a heavier weight to ensure The operating speed of the door opener will not be too slow, and the door opener also has a half-open function, that is, when there is no car or large objects in and out, and there are few pedestrians, the opening angle of the door leaf can be halved to prevent the door from being inside. Loss of heating or cooling.
If the flow of people is small, the doorway is average, and the investment budget is small, such as an office or office, you can choose an ordinary door opener with a lower price. This kind of door opener can generally be used without trouble, but the service life will be relatively short. If the purchase unit has good after-sales service and can provide in-place maintenance services at any time, you can use it with confidence.
For units that use secret places or restrict people's entry and exit, certain restriction devices should be added to the door opener, such as electronic synchronization locks, inductive access control, card readers, to restrict the entry of people without cards, and so on. This requires the door opener to have compatibility and be able to install these devices. Some automatic door openers have this kind of function, which is easy to install, but some door openers do not have this function, and they must be equipped with many devices to install, which leads to unnecessary expenses.
