Door Closer Function

Door closers are designed to close doors automatically after they have been opened. They work by controlling the speed and pressure with which the door is closed, avoiding the door from swinging too hard or too slow. The main principle behind the operation of a door closer is the use of a hydraulic damper or per to control the movement of the door.

Door Closer Type

1. Hydraulic Dampers: Door closers with hydraulic dampers are the most common and efficient. They use oil or other fluids to dampen the motion of the door, ensuring a smooth and quiet closing.
2. Spring: Door closers with springs use the stored energy in the spring to close the door. They are suitable for lighter and less frequently used doors.
3. Pneumatic: Pneumatic door closers use compressed air to control door movement. They are often used in environments where anti-fuel safety is a necessity, such as hospitals or laboratories.
4. Electric: Electric door closers use a motor to move the door. They are often used in applications that require access control, such as automatic doors at shopping centers or airports.

Benefits of Door Closer

1. Security: Door closers help prevent doors from accidentally opening, reducing the risk of intrusion or unauthorized access to buildings.
2. Convenience: They increase user comfort by automatically closing doors after use, avoiding noise and allowing easy access.
3. Energy Efficiency: Door closers help maintain room temperature by automatically closing doors, reducing air leakage and minimizing the need for additional heating or cooling.
4. Reliability: With hydraulic or perforated dampers designed for long-term reliability, door closers typically require little maintenance and have a long service life.
