The doors are in the normally open position. In traditional gates, the barriers are normally closed. This paradigm shift is what sets Free Flow gates apart from previous models.
Doors only close when unauthorized individuals, including piggybackers, try to pass through the gate. The closing system is quick and precise, employing new sensing systems and sophisticated algorithms.

dFlow is flexible in width, and may be deployed in various configurations. In the 900 mm or greater configuration, it ensures greater comfort for PwD and multiple users, as well as optimizing costs by decreasing the number of pieces of equipment and infrastructure.
Regardless of gate width, access can be set as one-way or two-way as needed.

Visual Identification with Light Windows LED signal lights follow users in their entire path through dFlow, with different colors for different groups of users. When deployed in schools, for instance, students can be followed by a green light window, educators by a yellow window, and family members by a blue window. Unauthorized users would be tracked by a red light window.
