An automatic door that performs well for several years is not particularly remarkable. What truly defines the value of an automatic door system is its ability to maintain reliable performance after millions of opening and closing cycles and years of continuous operation. This is why Sonha Auto launched the “Doors That Stand the Test of Time” series, documenting the journey of NABCO automatic door systems installed many years ago that continue to operate reliably in projects across Vietnam. The first story in this series features the NABCO automatic door at Cha Ca Gia Nguyen, which was installed in 2013 and has now recorded more than 5,735,905 opening and closing cycles. After more than 13 years of service, the system continues to operate smoothly, providing real-world evidence of both the equipment’s durability and the long-term value of scheduled preventive maintenance.
Why is durability the true measure of an automatic door’s quality?
In the automatic door industry, a system’s lifespan is measured not simply by the number of years it has been in service, but by its ability to maintain consistent performance after millions of operating cycles. Each opening and closing cycle places the motor, controller, guide rail, rollers, drive belt, and safety devices into operation. Over years of continuous use, every component is subjected to mechanical loads, friction, and environmental conditions.
According to recommendations from Japanese automatic door manufacturers such as NABCO, the quality of an automatic door system should be evaluated based on its long-term operational stability throughout its service life rather than its condition at the time of installation. A high-quality system should continue to deliver consistent opening and closing speeds, accurate sensor performance, smooth operation, and reliable safety after years of use.
For this reason, projects that have remained in operation for more than a decade while completing millions of opening and closing cycles are especially meaningful. They demonstrate not only the quality of the equipment itself but also the effectiveness of proper system design, professional installation, scheduled maintenance, and correct operation.
The NABCO automatic door at Cha Ca Gia Nguyen is a clear example, with more than 5,735,905 operating cycles recorded over 13 years of service.
The NABCO automatic door at Cha Ca Gia Nguyen after 13 years of operation
Installed by Sonha Auto in 2013, the NABCO automatic door at Cha Ca Gia Nguyen Restaurant is equipped with the NABCO TELE automatic door operator, serving as the restaurant’s main entrance where customer traffic is consistently high throughout the day. As an entrance solution for a busy restaurant, the system is designed not only to provide convenient access for guests but also to withstand intensive daily operation over many years.
According to maintenance records, the system has completed 5,735,905 opening and closing cycles after more than 13 years of operation. This is an impressive figure under real operating conditions. Every opening and closing cycle involves the motor, operator, guide rail, rollers, drive belt, and control system working together. After millions of such cycles, every component inevitably experiences mechanical stress, friction, and environmental exposure.
Despite these demanding conditions, the NABCO automatic door at Cha Ca Gia Nguyen continues to operate reliably without requiring a complete system replacement. This achievement reflects not only the exceptional quality of the equipment but also the importance of proper operation and professional maintenance throughout its service life.
What keeps the NABCO automatic door at Cha Ca Gia Nguyen operating reliably?
Many people assume that the service life of an automatic door depends entirely on the quality of the equipment. In reality, a durable automatic entrance solution for restaurants is always the result of two equally important factors: high-quality equipment and maintenance performed in accordance with the manufacturer’s standards.
Throughout its years of operation, the NABCO automatic door at Cha Ca Gia Nguyen has been maintained regularly by Sonha Auto following NABCO’s recommended maintenance schedule.
Each maintenance visit includes system cleaning, sensor inspection, guide rail adjustment, drive belt inspection, motor and controller evaluation, and early detection of component wear before it develops into major failures.
As a result, the system continues to operate at peak performance, minimizing unexpected breakdowns while extending the service life of the entire automatic door system.
Thanks to this standardized maintenance process, after more than 13 years of intensive operation, the NABCO automatic door at Cha Ca Gia Nguyen has required only routine preventive maintenance rather than a complete overhaul or full system replacement, allowing it to continue performing as reliably as it did when first installed.
What do 5.7 million opening and closing cycles prove?
For building owners and daily users, what matters most is simple: the door opens when needed, closes properly, and operates smoothly every day. From an engineering perspective, however, the NABCO automatic door at Cha Ca Gia Nguyen demonstrates the quality of an entire automatic entrance solution. More than 5.7 million operating cycles validate the system’s engineering design, the durability of its components, the motor’s load-bearing capability, and the long-term stability of the complete door system throughout its operational life.
This philosophy has always been at the heart of Japanese manufacturing: a truly high-quality product should not only perform well when newly installed but continue to operate reliably for many years afterward. After more than 13 years of continuous operation, the NABCO automatic door at Cha Ca Gia Nguyen stands as compelling proof of that philosophy.
Sonha Auto supports every project throughout its entire service life
With more than 20 years of experience in the automatic door industry, Sonha Auto provides far more than genuine NABCO automatic door systems and professional installation. The company also delivers comprehensive preventive maintenance programs, technical support, and long-term after-sales services. As a result, many automatic door systems installed by Sonha Auto since the early 2000s continue to operate reliably in hotels, hospitals, shopping malls, restaurants, and numerous commercial buildings throughout Vietnam.
Real-world projects such as the NABCO automatic door at Cha Ca Gia Nguyen demonstrate that the quality of an automatic door system is not determined at the time of handover. Instead, it is proven over time through millions of opening and closing cycles and years of stable, reliable operation.
