Bunka Daimajin High speed door

"What is a high-speed rolling door?

A high-speed rolling door is a type of rapid door often installed in warehouses, clean rooms, etc., with the aim of reducing heat loss, preventing dust, and blocking the entry of insects during the transportation of goods.

High-speed rolling doors are the perfect solution for cold storage warehouses, clean rooms, electronic equipment manufacturing plants, and food facilities. Additionally, they help businesses save a significant amount on electricity costs by minimizing heat loss in the room."

Technical Features of Bunka Daimajin High-Speed Rolling Door

The high-speed rolling doors Bunka Daimajin and Bunka Bead are manufactured using imported PVC curtains from Japan, showcasing unique and exclusive designs from the Bunka Corporation in Japan. These doors feature an intelligent connection between the curtain edge and the slide rail in the form of a pull-lock mechanism, ensuring superior airtight sealing. They operate smoothly at high speeds while maintaining resilience against high wind pressure and atmospheric pressures

Bunka High-Speed Rolling Door Features

Bunka Daimajin and Bunka Bead high-speed rolling doors enhance operational efficiency with their ability to open and close at speeds of up to 1.2m/s. They maintain controlled air environments and minimize the intrusion of insects and dust during the transportation of goods.

Pipeless Construction - Frameless Design

Due to their superior construction, Bunka Daimajin and Bunka Bead high-speed rolling doors do not require support frames within the curtain, accelerating the door's opening and closing speed. This design also eliminates the risk of damage in the event of impact from cargo vehicles.

Design for High Wind Resistance

Bunka Daimajin high-speed rolling doors exhibit outstanding wind resistance and high-pressure durability, thanks to the application of a unique force-transmission method in the rolling screen technology. As a result, these doors can be installed in outdoor locations with strong winds or areas with high pressure differentials.

High Sealing Design

The intelligent connection between the curtain edge and the pull-lock slide rail ensures excellent airtight sealing. This makes them an optimal solution for clean rooms, cold storage facilities, and more.

Obstacle Sensor Equipment

Bunka Daimajin and Bunka Bead high-speed rolling doors are equipped with advanced obstacle sensing systems, utilizing various methods such as photo sensors, infrared sensors, or loop sensors for forklifts. Upon detecting an obstacle, the doors automatically roll back to ensure absolute safety.

Self-Recovery Feature

In the event of an abnormal external force impact, such as a high-speed collision with a forklift, the curtain is pulled out of the guiding rail. A simple full opening operation restores the curtain, and the door resumes normal operation.

Exceptional Durability

Bunka Daimajin and Bunka Bead high-speed rolling doors have been tested and recognized for their superior durability compared to other products on the market. Over decades of collaboration with major global corporations such as Toyota, Honda, Canon, General Electric, they have proven to operate reliably and smoothly for extended periods, minimizing warranty and maintenance costs.
