The S900 Freezer Roll-Fast Doors are produced for internal openings up to 4000mm high by 3500mm wide, and are capable of being installed in areas with an air-pressure differential of no more than 15 pascals.
All doors are fitted with a durable 2mm thick vinyl panel.
The standard operational speed of the S900 Freezer Roll-Fast Door is between 900mm - 1000mm per second.
A through beam is installed within the doorposts to prevent the door from closing, should the beam be obstructed.
ACTIVE REVERSING EDGE:
Within the bottom rail, a self-guarding safety edge system is fitted. This system, when triggered, will return the door to the open position and “lock” the door in the open position until reset.
This system is microprocessor based with a speed variator, which is specifically designed for the operation of the automatic door, and is flexible to meet the changing needs of our customers.
