Advanced cam technology

The PDC100WR series uses cam technology to provide low opening resistance together with smooth and controlled closing torque. Closing speed can be adjusted through the adjustment valve, allowing the installer to tune the door movement to the application.

Revolving 360° movement

The WR series is designed for doors requiring a wide rotational range, with models supporting up to 360° movement. This makes the series suitable for architectural applications where conventional limited-angle pivot closers are not sufficient.

Hold-open configuration

The PDC105WR-S configuration provides 90° / 270° hold-open. Hold-open models are intended for locations where the door needs a defined temporary open position during frequent circulation.

Eccentric pivot installation

A key feature of the PDC100WR series is the ability to shift the pivot point along the width of the door. The closer can be installed at a non-central position, including approximately one-third of the door width, without reducing the stated load capacity.

Installation and adjustment

The concealed design allows quick installation without floor preparation. Final positioning can be adjusted by ±3 mm front/back, ±3 mm left/right and ±4° for alignment.

The NHN PDC105WR-S Revolving Pivot Door Closer is a concealed hydraulic door closer designed for heavy architectural doors that require smooth rotational movement and automatic closing. As part of the PDC100WR series, it combines advanced cam technology with a concealed pivot mechanism to reduce opening resistance while maintaining controlled closing performance.

The PDC105WR-S supports doors up to 200 kg and a maximum width of 2500 mm. The WR series provides a rotational range of up to 360°, making it suitable for applications that need more movement than a conventional 150° pivot closer.

The model is available in the 90° / 270° hold-open configuration. Closing speed can be adjusted to achieve suitable door movement, while the concealed construction keeps the hardware visually discreet.

The PDC100WR series also allows the pivot position to be shifted across the door width. This eccentric installation option provides greater architectural flexibility and, according to the manufacturer, does not reduce the load capacity. Final positioning adjustments of ±3 mm front/back, ±3 mm left/right and ±4° alignment help installers achieve accurate door positioning.

With an operating range of -20°C to +40°C, mechanical efficiency above 70% and a five-year warranty against manufacturing defects, the NHN PDC105WR-S is designed for demanding commercial and architectural door applications.
