High Speed and Energy Efficiency for Automated Storage and Retrieval Systems (ASRS)

Sure-Seal® High-Performance Door

With peak speed of up to 100 inches per second and extraordinary insulating capability, the Sure-Seal® high-speed conveyor door keeps operations running smoothly. Designed for non-live-traffic storage facility conveyor door systems, it helps maintain energy efficiency with minimal air infiltration. Within facilities with frequent opening and closing, each cycle helps maintain and control environments - particularly between conveyor operations and storage areas.

The Sure-Seal is the ideal warehouse retrieval door for non-live-traffic interior applications, including cold storage, where speed, low maintenance, and dependability are critical and can be built up to 6' wide x 13' high.
