NHN 85V Overhead Door Closer

NHN 85V Hydraulic Overhead Door Closer

The NHN 85V is a hydraulic overhead door closer for medium-to-heavy doors. Its spring force can be adjusted across EN 1154 sizes 3–6, providing a wider capacity range than the 83V and allowing the closer to be matched to different door weights.

• Closing force: EN 1154 sizes 3–6
• Maximum door weight: 120 kg
• Maximum door width: 1400 mm

Functions and options

The 85V provides adjustable closing-speed and latching-force control. NHN lists hold-open, backcheck, delayed-action, slide-arm and parallel-arm versions within the 85V range. These configurations should be selected according to the installation requirement rather than treated as standard features of every 85V package.

Applications

The 85V is intended for doors up to 120 kg and 1400 mm wide. Its adjustable EN 3–6 range makes it suitable for commercial and institutional applications where a higher closing-force range is required.

NHN 85V is a hydraulic overhead door closer designed for medium-to-heavy doors with an adjustable EN 1154 closing-force range of 3–6. It can be configured for doors up to 120 kg and 1400 mm wide, making it suitable for demanding commercial and institutional installations.

The slimline body uses an adjustable spring system so the closing force can be matched to the door. Closing speed and latching action can also be adjusted, helping installers achieve controlled and consistent closing performance. The NHN 80V family includes additional configurations such as hold-open, backcheck, delayed action, slide arm and parallel arm versions.

With its broad EN 3–6 adjustment range and non-handed design, the NHN 85V is a practical choice when a compact hydraulic overhead closer is required for heavier doors.
