Product Overview
The Dormakaba TS72 EN2-4 represents a robust and reliable solution in overhead door control. Engineered for internal and commercial applications, this hydraulic closer offers adjustable power ranging from EN2 to EN4, accommodating doors up to 1100mm wide. Its critical EN1154 certification affirms compliance with European standards for controlled door closing devices, underscoring its performance and safety credentials. The closer features independent adjustment of both closing and latching speeds via integrated valves, allowing precise management of the door's full travel and secure final closure. Constructed from durable metal, specifically steel and aluminium components, the TS72 EN2-4 is designed for longevity and consistent operation in demanding environments. Its non-handed configuration ensures straightforward integration into various door setups without requiring specific left or right-hand versions. While lacking advanced functionalities such as back check, hold-open, or delayed action, its core competency lies in delivering foundational, adjustable, and certified hydraulic door closure.

Engineering Analysis
The Dormakaba TS72 EN2-4 employs a sophisticated hydraulic mechanism to govern door closure. At its core, a spring-loaded piston system interacts with non-compressible hydraulic fluid. As the door opens, the spring compresses, storing energy. Upon release, this stored energy drives the door closed, with the hydraulic fluid passing through precisely calibrated orifices. The adjustable valves for both closing speed and latching speed allow engineers to fine-tune the fluid flow rates. The 'closing speed' valve controls the main sweep of the door from its maximum opening angle until just before the latching point, ensuring a smooth, consistent motion. The 'latching speed' valve then governs the final few degrees of travel, critical for overcoming latch resistance and ensuring the door closes securely into its frame, preventing slamming while guaranteeing proper engagement.
Compliance with EN1154 is a cornerstone of the TS72 EN2-4's engineering integrity. This European standard specifies strict performance requirements for controlled door closing devices, covering aspects such as operating forces, durability over repeated cycles (though a specific cycle test rating is not provided for this model, EN1154 inherently dictates a baseline for reliable operation), and consistency of closing force across the adjustable power range. The adjustable EN2-4 power size directly relates to this standard, indicating its suitability for doors requiring closing forces from EN2 (e.g., lightweight internal doors) up to EN4 (e.g., heavier internal or commercial doors up to 1100mm wide). This adjustability ensures optimal force application, preventing excessive strain on hinges or door frames for lighter doors, and providing sufficient force for proper closure on heavier, wider doors.
Regarding the specified `door_weight_capacity_kg` as 'up to 1100 mm', this is likely a misrepresentation in the product data, as weight is typically measured in kilograms. However, interpreting this in conjunction with the `door_width_capacity_mm` of 'up to 1100 mm', the EN2-4 power size provides the engineering context for actual door mass. An EN2 closer typically accommodates doors around 40kg, while an EN4 closer can handle doors up to approximately 80kg. Therefore, for doors up to 1100mm wide, the TS72 EN2-4's adjustable power caters to a broad range of corresponding door weights within these EN classifications.
It is crucial to note that the Dormakaba TS72 EN2-4 is not fire-rated. This absence means it does not meet the stringent material, performance, and integrity requirements mandated for fire door applications, and it should not be specified or installed where fire resistance is a regulatory necessity. The construction utilizes a robust steel/aluminium body, providing a strong yet relatively lightweight chassis for the hydraulic mechanism, finished in a standard silver for aesthetic integration.
