The Dormakaba UK TS71 Standard hydraulic door closer embodies precision engineering in its class. At its core, a robust rack and pinion mechanism operates within a sealed hydraulic chamber, leveraging a specialized hydraulic fluid to manage kinetic energy. This design facilitates consistent closing forces and speeds across varying operational conditions, ensuring predictable door control. The integration of independently adjustable valves for both closing speed and latching speed provides granular control over the door's final arc of movement. This allows for meticulous calibration to prevent abrupt door slamming and guarantee positive, secure latch engagement, crucial for both user experience and security protocols.
Compliance with BS EN1154 is a fundamental pillar of the TS71 Standard's engineering integrity. This European standard meticulously defines requirements for controlled door closing devices, covering aspects such as closing force, efficiency, durability, and safety. The adjustable power size of EN3-4 directly correlates with EN1154 classifications, enabling the closer to be correctly specified and installed to meet the fire performance and closing force demands for doors up to 1100mm wide and 80kg. While a specific cycle test rating is not explicitly provided, its EN1154 certification inherently mandates extensive durability testing, confirming its capability for long-term, reliable operation in demanding environments.
Furthermore, the 'fire rated: true' designation, supported by UKCA and CE certifications, confirms its suitability for installation on fire-rated door assemblies, providing a critical component in passive fire protection strategies. The non-handed configuration and overhead mounting capability simplify installation logistics, reducing potential for error and enhancing field adaptability. Constructed from a durable aluminium/steel alloy, the 1.2kg unit offers a compact footprint (232x45x68mm), marrying structural integrity with a sleek, silver finish suitable for various architectural aesthetics.
