PDC100 Series – Pivot Door Closer | Smooth, Efficient, Hidden Door Closing Solution
The NHN PDC100 Series Pivot Door Closers represent the next generation of hidden pivot door closers designed for architectural elegance and high-performance operation. Whether for glass doors in modern offices or interior entrances in commercial environments, this series delivers effortless opening, controlled automatic closing, and sleek aesthetics — with no visible mechanisms to disrupt your design.
Overview – What Makes the PDC100 Series Special?
The PDC100 Series is engineered to provide:
-
Hidden installation — integrates inside the door pivot hardware for a clean visual appearance
-
High operational efficiency — featuring the latest cam-type technology for easy opening and smooth, controlled closing
-
Adjustable performance — closing speed can be fine-tuned via dual valves
-
Flexible models — with or without a “hold-open” position at 90°
-
Double-action capability — doors can swing both directions
-
Durable design — supports doors up to 100 kg in weight and widths up to 750–1250 mm depending on the model
This combination of functionality and minimalist design makes it ideal for modern interiors, corporate offices, luxury retail spaces, and hospitality environments where design matters as much as performance.
Core Features & Benefits
Smart Cam-Type Technology
The PDC100 Series incorporates advanced cam-type mechanics for a light, effortless opening while maintaining high closing torque — reducing the effort required to move the door.
Two-Speed Adjustment
Separate valves allow precise adjustment of:
-
Closing speed (from fully open to near closed)
-
Latching speed (final movement to fully closed)
This gives installers and end users more control over how the door behaves in daily use.
Double Action & Hold-Open Options
Models are available with or without a 90° hold-open position, enabling doors to remain open when needed — while still closing securely when released.
Non-Handed, Easy Installation
The PDC100 Series is non-handed — compatible with right and left opening doors — and installs quickly without complex floor preparation, saving both time and labor.
Wide Operating Range
Designed to perform in temperatures from -20°C to +50°C (-4°F to +122°F), the PDC100 maintains smooth operation in diverse environments.
Multiple Finish Options
Standard finishes include satin and polished stainless steel, with additional finishes available on request to match architectural designs.
Model Breakdown
| Model | Hold-Open | Max Door Width | Max Weight | Max Opening Angle |
|---|---|---|---|---|
| PDC100 | No | 750–1000 mm | 100 kg | 150° |
| PDC100-S | Yes (90°) | 750–1000 mm | 100 kg | 150° |
| PDC105 | No | 750–1250 mm | 100 kg | 150° |
| PDC105-S | Yes (90°) | 750–1250 mm | 100 kg | 150° |
These options allow you to choose the ideal version based on door size, desired hold-open behavior, and architectural requirements.
Applications & Uses
The PDC100 Series is perfect for:
-
Glass doors in commercial and office environments
-
Interior pivot doors in residential and corporate spaces
-
Design-centric installations where visible closers would interfere with aesthetics
Its performance and hidden design make it especially suitable in spaces that prioritize both form and function.

✔ Easy installation and adjustment
✔ Flexible configurations to suit various design needs
