High-speed door
In North America, the Door and Access Systems Manufacturing Association (DASMA) defines high-performance doors as non-residential, powered doors, characterized by rolling, folding, sliding or swinging action, that are either high-cycle (minimum 100 cycles/day) or high-speed (minimum 20 inches(508 mm)/second), and two out of three of the following: made-to-order for exact size and custom features, designed to be able to withstand equipment impact (break-away if accidentally hit by vehicle) or designed to sustain heavy usage with minimal maintenance.
To achieve this they generally have a strengthened drivetrain, strong but lightweight PVC curtain (usually with a vision window for visibility) and a high speed industrial motor.
Food, clean, and pharmaceutical processes: In the strict environmental constraints of pharmaceutical and aggressive environments of the food processes, where hygiene is imperative, doors must not only provide a structure made of stainless steel or composite materials to prevent corrosion, but they must also ensure an exposure time as short as possible to reduce the risk of airborne contamination.
High-speed doors are vital for the logistics processes, high speed and low maintenance ensures optimum production.
High opening speeds minimize the waiting time in front of the doors and thus accelerate the logistic processes, and control temperatures and pressure differences while saving energy, isolating clean areas from airborne contamination but still optimizing traffic flow.
In places where men work with highly volatile and flammable products, the best advice is to rely on a manufacturer of rapid flexible doors, guaranteed and reliable.
Hangar Zone: With large openings where high-speed doors work in airports and naval ports it is required to provide an easy, quick and safe passage from inside to outside, and vice versa.
Although the deposits of naval vessels are a very difficult environment to operate, places where the service of maintenance to ships or insurance protection from the sea can be requested at any time.
The door's main objective is to produce a high opening speed and the guiding system must allow smooth operations with minimal friction.
In Europe, after a few incidents due to the excessive speed of the curtain and the stiffness of the embedded sensor, the European Community has implemented new regulations (EN 13241-1).
