The Dorma TS83 is a versatile, rack-and-pinion overhead door closer engineered for use in demanding commercial and public environments. Featuring an adjustable power size of EN 2-5, it provides a reliable closing solution for a broad range of door dimensions, ensuring consistent performance regardless of door weight or traffic levels.

A primary technical feature of the TS83 is its "thinking" backcheck system. This self-regulating damping mechanism offers progressive resistance when the door is opened forcefully, significantly reducing the risk of damage to the door leaf, frame, and surrounding structure. This makes it an ideal choice for external doors exposed to wind or internal doors in high-frequency use areas.

  • Applications: Recommended for single-action doors, including fire-rated and smoke protection assemblies.
  • Compatibility: Designed for standard installation on the pull side. For push-side applications, a parallel arm bracket is required.
  • Functionality: Provides independent adjustment of both closing speed and latching action to ensure smooth operation and secure engagement of the latch.

Whether used for new installations or as a heavy-duty replacement for existing hardware, the TS83 offers a durable and adaptable solution for maintaining building security and fire safety standards.

FAQs

The Dorma TS83 is designed for doors with a width of up to 950mm. With a variable spring strength of EN 2-5, it provides the versatility needed to accommodate a wide range of standard door sizes and weights.

As standard, this door closer is suitable for pull-side installation. If you intend to mount it on the push side of a door, a separate parallel arm bracket will be required to complete the setup.

The integrated 'thinking backcheck' acts as a cushion to protect the door and the adjacent wall from damage. It works by providing resistance when the door is opened with excessive force or speed, slowing it down before it reaches its full opening capacity.

One of the key advantages of the TS83 is its ease of adjustment. It is engineered to allow simple fine-tuning of the closing speed and latching action, ensuring the door operates smoothly and securely for your specific environment.
