Electric door closers can only control the positioning and automatic closing of the door, not automatic opening. Because the automatic door opener is driven by a motor, it can realize the automatic opening and closing of the door. There are also differences in the scenes used. Electric door closers are generally used for normally open fire doors, and they must be able to automatically close the door in case of fire and isolate the fireworks. The automatic door opener is suitable for channel casement doors, which can realize intelligent induction and contact-free automatic door opening and closing, and can also be connected to the access control system to open the door by swiping the card or fingerprint.</p>
