Door Opening and Closing Unit is a product developed for use in places that require ease of opening and closing, as well as security. For example, in elderly nursing homes, it is very important for the elderly to open and leave the Hinged Automatic Door easily and to close the door by itself. Because when someone goes out, nobody notices and the door remains open, an uncontrolled environment is created. Using pusher instead of Automatic Door Unit creates danger in such places and it is difficult to use. Opening-closing speed adjustment is not possible, nor is it suitable for automatic locking. It is a matter of elderly people squeezing their hands, arms and feet. In the same way, the safety of both the person and the place is of utmost importance in childcare centers. Safe opening and closing are needed. At the same time, it is imperative to provide environmental control in case of theft and the possibility of undesired persons or animals entering. Hinged Automatic Door Unit is a savior for such institutions and even residences.
