ASSA ABLOY DC140 Door Closer with Arm EN 2/3/4/5 White Thermodynamic Valve 100kg

Product Overview

The Assa-Abloy DC140 door closer with arm is engineered for use on all door types, including fire-rated and smoke-control doors, in commercial, institutional, and residential settings. Certified to EN 1154, it covers EN 2/3/4/5 closing forces for doors up to 1250 mm wide and weighing up to 100 kg. The thermodynamic valves eliminate the need for seasonal adjustment, ensuring consistent performance in varying temperature conditions.

Its differentiator is the integrated thermodynamic valve system, which allows for stable closing speed and back-check regulation regardless of ambient temperature fluctuations. This feature reduces installation and maintenance risk for facilities managers in climate-diverse regions. The DC140 is recommended for bulk procurement projects in offices, schools, hotels, and public sector buildings, where compliance and long-term reliability are required.
