Where is a high speed door used?

High speed doors are powered sliding or rolling doors that are designed to open and close fast. The primary purpose of high speed doors is to maintain climate differentials in enclosed areas by drastically reducing the transfer of heat or cold from one area to another. High speed doors are usually installed in industrial and commercial settings where there is a high degree of vehicular traffic such as forklifts going from one area to another. These high speed doors can operate at speeds of one foot per second in both directions and when installed can save the owner considerable money in heating and cooling. Although these doors are normally used to reduce heat transfer they also are used to ensure that airborne materials cannot move between areas although this is less of a problem area.

Every time a vehicle or a person goes through a door, especially a large commercial door such as may be found at a shipping and receiving bay or between departments, valuable seconds are lost for heat and cool air to migrate from either direction. It can be very expensive when heat flows out of a building in the winter months, conversely it can be equally as expensive when chilled air flows out of a commercial chiller or freezer area in food processing plants. The objective is to ensure that the door does not remain open any longer than it takes for the person or vehicle to pass through.

There are many areas where maintaining a set temperature is extremely important. Examples of these areas are laboratories, ice-cream manufacturing plants and cold storage warehouses. When the temperature deviates drastically it can have harmful effects on the product or the process and a high speed rubber roll-up door can ensure that the temperature controlled side of the opening is exposed to the uncontrolled side as short of time as possible, keeping the temperature transfer to a minimum.

Because these doors close quickly it is important that they be fitted with devices which will stop the doors motion and reverse it in the event the vehicle or person has not cleared the opening. Most installations use two systems to ensure redundancy, one is a pressure sensitive bar on the bottom of the door and the other is a set of photo-optic sensors.

High speed doors are manufactured by PerforMax Industrial Rubber Doors. These doors are designed to operate at speeds up to 36 inches per second through the use of a high efficiency right angle motor and gearbox. For more information visit online.
