Aluminum framed glass door with door closer

What is an automatic door closer?

An automatic door closer is a mechanical or hydraulic device installed above the door, which can automatically close the door after it is opened. The common door closers are mainly composed of components such as hydraulic cylinders, reset springs, and speed regulating valves. The working principle is that when the door is pushed open, the hydraulic oil in the door closer flows through the speed regulating valve under the pressure, controlling the speed at which the door closes; when the door is about to close completely, the door closer will automatically adjust to make the door close gently, avoiding violent impact.

Where can the aluminum glass doors with locks be used?

• Commercial places: such as shopping malls, office buildings, hotels, etc. These places have a high volume of people flow. Automatic door closers can ensure that the doors close promptly after people enter or exit, maintaining the indoor temperature, humidity, and quiet environment. For example, the doors of various stores in a shopping mall and the public areas in an office building, using automatic door closers can prevent the loss of cold air or hot air, reducing the energy consumption of air conditioning, and also reducing the interference of external noise on the indoor office or shopping environment.
• Public buildings: hospitals, schools, libraries, etc. In hospitals, automatic door closers can ensure that the doors of wards, operating rooms, etc. close promptly, maintaining the hygiene environment and quiet atmosphere in the room, which is conducive to the rest and treatment of patients; in schools, they can ensure that the classroom doors close promptly after students enter or exit, ensuring that the teaching order is not disturbed by the outside world.
• Residences: especially some high-end residences, villas, or residences with fire safety requirements. Installing automatic door closers on the entrance doors or the doors leading to the stairwell in residences can, on the one hand, enhance security and prevent strangers from entering at will; on the other hand, in case of emergencies such as fires, they can automatically close the doors to prevent smoke and fire from spreading.

The advantages of installing a door closer on an aluminum-framed glass door decoration

• Safety Assurance: The automatic door closer can effectively prevent the door from being accidentally or maliciously left open for an extended period, thereby preventing strangers from entering the indoor area at will and ensuring the safety of personnel and property within the premises. In emergency situations such as fires, it can quickly close the door to prevent smoke and fire from spreading through the door, allowing for more time for personnel evacuation and fire rescue. For example, in high-rise buildings, the doors of stairwells are equipped with automatic door closers, which can effectively prevent smoke and heat generated by a fire from entering the evacuation corridors, ensuring the safe evacuation of personnel.
• Extending the service life of the door: By controlling the speed and force of the door closing, the automatic door closer can reduce the impact between the door and the door frame when it closes, decrease the wear of components such as the door body, hinges and door locks, thereby extending the overall service life of the door and reducing maintenance and replacement costs. In places with high foot traffic like shopping malls, if the door that is frequently opened and closed does not have an automatic door closer, the door body is likely to be damaged due to violent impacts.
• Environmental Control: In some places where there are specific requirements for temperature, humidity, and cleanliness, the automatic door closer can ensure that the door closes promptly, maintaining stable environmental conditions inside. For example, in laboratories and dust-free workshops, the automatic door closer can prevent external dust and impurities from entering, maintaining the cleanliness of the room and ensuring the normal operation of experiments or production activities; in some indoor spaces equipped with air conditioners, the promptly closed door can reduce the loss of cold and hot air, lower energy consumption, and save operating costs.
• Convenience: For those who carry items with both hands, the automatic door closer eliminates the need for them to manually close the door, providing great convenience. For instance, customers who have purchased a large quantity of items at the supermarket, or medical staff pushing hospital beds, the automatic door closer enables them to pass through more easily without the need for additional actions to close the door.
