A high speed door is a flexible and light-weight door, designed for intensive industrial use, which, thanks to the speed of operation, minimises air currents and ambient temperature losses and helps to make traffic flows more efficient.
The improvements to working conditions and savings in energy expenditure help to make these doors an investment which soon pays for itself.
An industrial maintenance door is opened on average between 200 and 400 times a day. A rigid automatic door, whether sectional, overhead or other, measuring approximately 4,000 x 4,000 mm, has a maximum waiting time for opening of approximately 10 seconds and for closing of 60 seconds. Therefore with a minimum of 200 operations a day, the door will be open for more than three hours per day.
When the same calculations are applied to a high speed door, with an operating speed of 1 m/s and a pause of 7 seconds (door opens in approximately 15 seconds), the difference in the speed of the operation is 45 seconds: More than 2.5 hours per day extra with the door closed!
This is equivalent to 2.5 hours of energy savings per day and a substantial improvement in productivity as waiting times for the door to open are reduced fivefold.
High speed doors can be divided into two main groups: those with an industrial fabric folding system (Instant-Pass) and those made of roll -up canvas (Instant- Roll, Mirflex, Hermetic-Roll, etc.).
The efficient folding fast door system:
Specially designed for exposed entrances or entrances subject to significant changes in air current or wind without coming off the guides, without being subject to wear and tear, tears or deformations and remaining unaltered for many years.
The efficient rolling fast door system:
The Instant Roll High Speed Door has been designed to take up a minimum amount of headroom allowing them to be fitted in tight and small spaces.
The Instant Roll® ECO is the lightweight version of the Instant-Roll door. It has adequate provisions for medium size openings with moderate air pressure for indoor use.
A rolling door for medium size openings, ideal for separating different environments and passage ways between buildings, warehouses or stores. Designed with different small size profiles, they take up little of the opening’s light space and require little space on the side bracelets and on the lintel. They are resistant to moderate air currents and the curtain has a system of flexible reinforcements that come off the guides when they receive a strong impact and roll up again when the door opens.
