Benefits of Automatic Sliding Door Opener 

These days, building owners are installing automatic doors in their premises to enhance security & pleasure. Previously, secure access control and automatic doors were two different door entry systems. However, with high tech design and modern materials, both are combined without compromising on the security aspect. Automatic Sliding Door can be maintained which are aesthetic in looks. When security is concerned pertaining to entrances, it mostly relates to fire, safety and access control.

Greater convenience

There are many places where doors are expected to open by itself as they approach commercial & public premises. High street stores and shopping centers have adopted automatic doors. This is to improve customer convenience and to help them enter the premises easily and effortlessly. From commercial view point, they are likely to conserve energy and help determine pedestrian flow.


This type of door system has been designed for maximum 150 kg load. It has opening speed of around 150-460mm/s. The power consumption is 65W(125A) and 50W(125B).


Prior to each closing moment, safety photocell is carefully checked. The door’s regular checking does ensure that it operates efficiently and smoothly at all times. Also it is safe to be used.

It will be necessary to have adequate information prior to making any decision so as to make the correct selection. Installing the most appropriate type of automatic sliding door opener will help to derive all its benefits while increasing productivity and efficiency.
