Sealed – Silent – Reliable

Besam hermetically sealing sliding door system Besam Hermetic is especially designed for use in clean room environments, such as operating
theatres, pharmaceutical production facilities, food preparation facilities, laboratories and other areas where clean, hygienic, well-sealing doors are required.
The Besam Hermetic system consists of operator, door and door frames. It is easy to install for both new construction and retrofit applications. Although the operator is small and slim in appearance, it is entirely suitable for the heaviest duty applications. During the installation the operator is programmed to comply with the customer’s specific requirements.

No compromise on safety
To permit safe passage between closing doors, the doors immediately reverse if an obstruction is detected, then resume their interrupted movement at low speed to check whether the obstruction has disappeared or not. If an obstruction is detected between opening doors and surrounding walls or interior fittings, the door immediately stops and then closes after a time delay.
The safety can be further improved by using a Besam presence detection system. People or objects in the doorway are detected and the door is then prevented from closing until it is safe to do so. A convenience battery is available as an accessory. This is a standby supply, which gives continued operation during a short power failure.

Self-monitoring
The microprocessor has an integral self-monitoring  device which detects any interference or faulty signals in door operation and takes necessary measures to ensure a safe operation. The electronics are grouped in plug-in units. Each unit is sub jected to a programme of stringent quality tests before delivery.
