High speed double roller door for cleanrooms
Hart Door Systems has developed a new variant of its successful Speedor Cleanroom high-speed roller door by incorporating twin door blades to meet an exacting air leakage requirement.
This was required for a particular industrial application where the possible transfer of air particles was a perceived risk. The standard Speedor Cleanroom attains a very good rating at 18m3 per hour. By combining an additional door blade Hart has been able to reduce the air leakage rate to just 2m3 per hour with up to 30Pa pressure differential over the door system. The twin blade construction ensures efficient and effective separation from the contamination zone.
In addition to the unique twin blade design, the Speedor Twinblade has high-performance compression seals on the side frame. These are electrically and pneumatically operated when the door is in a closed position. Being a ‘cleanroom’ product, the door frame, bottom rail and covers are stainless steel, brush finished with easy clean seals to prevent contamination spread.
This bespoke system is a significant step forward for industrial roll up door development for potential contamination zones. It has passed third-party assessment over a rigorous testing procedure.
