A UK nuclear research facility needed a solution to remotely close and lock steel blast doors in a radiologically active area. This safety-critical requirement demanded a door closure system that delivers outstanding operational reliability, maintaining radiological containment and protecting people from harm.
DHX designed, built and installed a hydraulically powered, remotely operated door closure and locking system. The process is automated, closing and securing the robust, twin–leaf steel doors in a single, simple operation. Each door is driven by a dedicated hydraulic power unit for greater control and reliability.
Each door leaf is powered by its own hydraulic cylinder and power unit, ensuring smooth and reliable movement.
The system is managed by an intuitive electrical control cabinet, with preprogramed PLC software, enabling automated operations
Overlapping doors provide complete and secure closure, with the first door programmed to close slightly ahead of the second.
Top and bottom hydraulic shot bolts lock each door firmly in place, powered via separate hydraulic cylinders
The system includes emergency stop functions for added safety.
