The Market-Leading Certified & Compliant ATEX Door by Dynaco
Innovative High Speed Doors For Maximum Safety & Efficiency
Energy Savings
Dynaco ATEX doors conserve energy in two crucial ways. Firstly, the unique push-pull design provides the shortest door opening time in the industry. Fast cycle times significantly reduces the transfer of conditioned air. Additionally, Dynaco incorporates patented seal technology which provides the tightest seal possible around the full perimeter of the door.

Cost Savings
High speed roll up doors are provided with a patented re-insertion system. When dislodged, the curtain automatically returns into its side guides, without the need of intervention. This way, you can avoid costly downtime and time-consuming technical interventions.
Durability
Dynaco doors contain very limited wearing parts. The strong and flexible curtain is very resistant to service life degradation. Dynaco ATEX doors can operate during hundreds of thousands of opening cycles. Investing in a Dynaco door will ease your life for a very long time.
High Efficiency
Dynaco offers a wide range of opening commands. Automatic opening and closing results in considerable time savings and improves the efficiency of your daily operations.
Extreme Safety
Free of rigid components, Dynaco’s soft, flexible curtain cannot injure an unprotected person who accidentally impacts the door. The soft curtain also presents no risk to an unsuspecting person on the opposite side of an impacted door.
PartiTIoning of Hazardous Area Zones
ATEX zones require specific explosion proof equipment, extra safety measures, special certifications and regular inspection and maintenance. Partitioning such ATEX designated areas to reduce the zoned surface area helps to reduce both capital and operating expenditure. Where users still need to maintain good workflow, such as the transportation of bulk materials, the Dynaco S-5 ATEX door provides the solution. The ATEX high speed roll up doors have a reduced footprint requiring little space and all are supplied with an official 3rd party certificate to ensure site compliance with ATEX.

Partioning & Segration of Hazardous Area Zones | Reducing Capital Expenditure & Operating Costs

The doors provide uninterrupted workflow due to a self-reinserting curtain with unique zipper. Unlike rigid doors, the Dynaco ATEX door has a fully flexible curtain, uses patented push pull technology and is self-reinserting. This means there are no expensive repairs or downtime resultant from unintended and accidental forklift impact damage.
