What Is a Roller Shutter?
Roller shutters are shutters used for building entrances and exits. Generally, shutters are made of steel, roller shutters are made of plastic sheets such as vinyl or polyester.
Most sheet shutters are electrically controlled to open and close, and are widely used as loading doors in factories and warehouses.
Compared to conventional steel shutters, roller shutters are lightweight and can be opened and closed quickly, making them useful for applications such as insect control, dust control, and air conditioning control.
Applications of Roller Shutters
Roller shutters are used in food factories that require a high level of hygiene control and in warehouses where frequent loading and unloading takes place.
Because they are electrically operated and can be opened and closed quickly, they have the advantage of keeping cold or warm air from escaping and keeping insects and dust from entering the facility.
Compared to steel shutters, roller shutters have fewer metal parts and are free from rust and other contaminants, making them superior in terms of hygiene management.
Principle of Roller Shutters
A winding drum and motor are contained inside the winding section at the top of the shutter, and the drum motor rotates forward and backward in response to signals issued by an operation switch or sensor to raise and lower the shutter.
The shutter can be raised or lowered manually using the control switch or pull switch, or automatically opened or closed when a person or vehicle stands in front of the shutter using a motion sensor or vehicle sensor.
A countdown monitor or other accessory component can be used to close the shutters automatically after a set time, such as 100 seconds after the shutters open.
A phototube sensor is built into the guide next to the shutter to detect any obstacles, such as people or luggage, as the shutter descends and stops the shutter to prevent entrapment or entrapment accidents.
It is also possible to install a roller with an insect repellent effect to cut ultraviolet light that attracts insects.
