ASSA ABLOY DC140 Door Closer EN 2/3/4/5 Anthracite Thermodynamic Valve 100kg 1250mm

Product Overview

Assa-Abloy DC140 is a door closer equipped with an arm, certified according to EN 1154 for universal use in residential, commercial, and industrial environments. It supports door wings up to 100 kg and a maximum width of 1250 mm, functioning on left- and right-hand doors, and is suitable for installation on both the door leaf (hinge side) and frame (opposite hinge side). Designed for demanding situations, including fire and smoke protection doors, it incorporates thermodynamic valves to ensure reliable operation without seasonal adjustments.

One key differentiator of this model is its maintenance-free thermodynamic valve system, which eliminates the need for regular recalibration due to temperature fluctuations?a common issue with conventional door closers. This feature reduces service intervals and mitigates the risk of non-compliance on fire and smoke-rated doors in facilities with stringent maintenance requirements. The DC140 is ideal for professional installers and facility managers overseeing large commercial buildings or multi-door installations requiring certified, low-maintenance closing solutions.
