The DS-K4DC105 is an automatic door closer designed to ensure smooth and efficient door operation. It is suitable for doors with a width of 1,100mm and can support door weights ranging from 80 to 120 kilograms. This door closer is engineered to offer an optimal balance between speed and control, promoting safety and reducing the risk of damage. For ideal performance, it is recommended that the door closing speed be faster when the door is moving from a wide-open position of 180° to a nearly closed position of 15°. This rapid closing speed helps in quickly closing the door while still providing ample time for safe passage. Conversely, from 15° to 0°, the closing speed should be slower. This slower speed prevents the door from slamming shut, thereby minimizing the risk of the door leaf colliding with the doorframe and causing potential damage or injury.
