The NABCO GT20 automatic swing door has been a familiar choice in projects such as hospitals, office buildings, and shopping malls thanks to its stable operation and flexible installation. However, as this product line has been discontinued, the need for a more suitable and modern replacement solution has become increasingly urgent. To meet this demand, the NABCO GT20A automatic swing door was developed as a comprehensive upgraded version. It inherits the advantages of GT20 while significantly optimizing performance, durability, and real-world operation. This is the ideal replacement solution for projects requiring upgrades or new automatic door installations.
Overview of NABCO GT20 automatic swing door
The NABCO GT20 automatic swing door is an automatic hinged door system designed for both new construction and retrofit projects. With a compact structure integrated with modern control technology, this system meets a wide range of needs—from lightweight interior doors to heavy-duty exterior doors.
Unlike many automatic swing doors on the market, GT20 focuses on long-term stable operation, minimizing maintenance while still ensuring high performance under all conditions.
This is also one of NABCO’s representative swing door models, clearly reflecting the Japanese design philosophy: minimalistic yet efficient, durable, and safe.
Key features of NABCO GT20:
- A single motor for both high-power mode and energy-saving mode
- Easy switching between high-power and energy-saving modes
- Fully automatic operation without manual handling
- Automatic force adjustment under strong wind conditions
- Self-diagnostic capability for fault detection
- Adjustable opening/closing speed, hold-open time, and motor output
- Mechatronic motor ensures smooth and quiet operation
- Emergency escape function in case of fire or urgent situations
- Suitable for both new construction and retrofit projects
- All features, components, and parts comply with ANSI A156.10/A156.19 standards
The control circuit with an integrated LCD display and motor provides users with door initialization guidance. No additional external devices are required. Illuminated buttons for program selection and a mode switch are conveniently integrated next to the unit housing, making operation user-friendly.
The standard push arm is the most effective method to maximize the performance of the NABCO GT20 automatic swing door.
The slide arm with push/pull functionality is the most common and aesthetically pleasing option for GT20 automatic swing doors.
Why is GT20 no longer in use?
The discontinuation of GT20 is not due to quality limitations, but rather the result of evolving technology and increasingly stringent safety standards. As modern buildings demand higher energy efficiency, improved operational safety, and stable performance under complex environmental conditions, NABCO developed GT20A as a fully upgraded replacement to better meet real-world requirements.
NABCO GT-20A automatic swing door – A comprehensive upgrade
Compared to GT20, the NABCO GT-20A automatic swing door not only retains existing advantages but is also significantly improved in both technology and operational performance. The system maintains a flexible design suitable for various building types, while being upgraded into a more modern, safer, and more energy-efficient NABCO swing door solution.
This product line is currently officially distributed in the Vietnamese market, suitable for both new installations and retrofit projects.
GT20 vs GT20A – Where are the differences?
If GT20 was once an effective entrance solution, GT20A represents a step forward in enhancing operational experience. GT20A shows clear improvements in system control, performance optimization, and safety enhancement. The automatic swing door motor system is optimized for smoother operation while reducing energy consumption.
In addition, GT20A is highly rated among energy-saving automatic doors, helping reduce long-term operational costs—an important factor for large-scale buildings.
Stable operation in real conditions – Wind-resistant automatic door solution
One of the key improvements of GT20A is its enhanced adaptability to environmental conditions. The system is optimized as a wind-resistant automatic door solution, ensuring stable operation even in areas with high wind pressure such as outdoor entrances, high-rise buildings, or coastal regions.
Its automatic force adjustment capability ensures smooth opening and closing, minimizes vibration, and extends system lifespan.
Main entrance automatic door solution – Flexible for all projects
With its technological and operational improvements, GT20A is not only a replacement product but also a complete automatic door solution for main entrances across various types of buildings.
From hospitals and office buildings to shopping malls, this automatic swing door system optimizes traffic flow, enhances user experience, and maintains a professional appearance. Especially for retrofit projects, GT20A allows quick replacement of existing systems without requiring major structural modifications.
