How does a high speed door work? The majority of high speed doors are driven by sophisticated mechanical and electrical elements, which enable opening and closing at very high speeds, often up to 1 meter per second, much faster than conventional doors. They find their perfect application in various fields like industry, commerce, and logistics, where fast entrance is required along with environmental control and security. A high-speed door would typically be composed of a motorized drive system, which, in turn, is linked with springs and rollers allowing the door to move rapidly up and down its tracks. The drive motor ranges from 0.5 to 3 kW according to the size of the door and usage, while the intelligent control system is coupled with a motor that allows smooth operation. These sensors will be installed to detect motion and control the speed, direction, and stop of the door. The rapid opening and closing mechanism of the door minimizes energy loss through reduced time availability for energy to escape. For instance, in the case of a warehouse, high-speed doors minimize up to 50% heat loss, which significantly contributes to energy efficiency and overall cost savings.
Material-wise, high-speed doors are made of durable fabrics or composite materials, including PVC and reinforced polyester, which can resist heavy usage. These materials have been gauged to resist impacts and harsh conditions. For instance, some high-speed doors applied in the food processing industry where hygiene and temperature control are of essence are designed in such a way that they can resist cleaning chemicals and moisture.
In 2018, a global manufacturer of industrial doors reported a 25% increase in sales of high speed doors, driven by their ability to improve efficiency in busy environments like logistics hubs and manufacturing plants. As logistics director John Davis noted, “We’ve saved significant time in our warehouse operations by installing high speed doors. They reduce our forklift downtown and keep our work environment safe by limiting exposure to external conditions.” This is one of the main reasons high speed doors are becoming standard in so many industries: their ability to improve workflow efficiency and safety.
Safety features in high speed door technology include sensors that detect an obstruction and prevent the door from closing, as well as emergency stop buttons that provide extra safety. The need for quicker processing times and smooth workflows has made high speed door a key component in industries such as food and beverage, pharmaceuticals, and automotive manufacturing. The life expectancy of a high-speed door can be typically from 5 to 10 years, based on usage, but they are designed to be rugged and durable and, hence, may prove quite cost-effective over a period of time.
High-speed door systems come with the right level of reliability, efficiency, and safety features to help industries maintain their operations properly and efficiently.
