Suitable for heavy-duty doors. The same type is applicable to left/right overlapping doors, flush doors, and recessed doors.
ADITECH Surface-mounted door closers are employed in scenarios where the randomness of door movement needs to be controlled while ensuring low-noise closing. Quiet, gentle, and safe operation – this is how door dampers function. "This requirement is achieved through a combined damping and traction mechanism, with the closing speed adjustable by the customer. ADITECH surface-mounted door closers can be installed on doors in all types of buildings and rooms, including sauna areas. They are also utilized for heavy-duty gates as well as in refrigeration and air conditioning technology. These closers are suitable for doors weighing up to 200 kilograms (depending on spring strength and type).
The same model is used for both right- and left-hand doors, though there are distinctions among three door types. Depending on the application, the closing force ranges from 15 to 80 Newtons. The closing speed of all door closers can be adjusted by turning the piston rod with a hex wrench. By using specialized oils, they can operate within a temperature range of -30°C to +90°C. Based on specific requirements, ADITECH offers fire-resistant hydraulic oils and biodegradable oils for its door closers. According to the damping type, ADITECH door closers feature progressive damping characteristics.
