ATEX Doors: High-Speed Roll-Up Doors for Hazardous Areas

High-speed doors can help separate working areas, manage access and protect industrial environments from external conditions. Where a facility contains a potentially explosive atmosphere, the door and its associated equipment must suit the site’s hazardous area classification.

Thorne & Derrick supplies ATEX high-speed roll-up doors, including selected Dynaco door solutions for hazardous area applications.

Case Study: ATEX Doors at Evonik Nutrition & Care

Evonik Nutrition & Care GmbH produces speciality chemicals for a range of industries. The company approached Entrematic in Belgium to find a door solution for a facility where potentially explosive atmospheres required careful consideration.

The installation needed to help protect the internal working environment from direct sunlight and external weather while allowing forklifts to move easily between the storage area and the wider facility.

Entrematic Belgium worked with a local distributor to install a Dynaco S-549 high-speed ATEX door. The door provided access to stored active ingredients within a classified hazardous area.

Project Requirements

Provide convenient forklift access to the storage area.
Help protect stored products from direct sunlight and adverse weather.
Support frequent movement through the doorway.
Allow the door curtain to reinsert automatically following an impact, as described in the original case study.
Meet the requirements of the site’s hazardous area classification.

Installed Solution: Dynaco S-549

Entrematic Belgium supplied a Dynaco S-549 door measuring 5,500 × 3,700 mm. The original case study identifies this installation as a Category 2, Zone 2 ATEX door. Confirm the installed unit’s exact certification and configuration against the project documentation before using this case study as a specification reference.

Benefits of High-Speed ATEX Doors

High-speed doors for hazardous area applications

Improve Energy Efficiency

High-speed doors can reduce the time a doorway remains open, helping limit heat transfer between areas. The potential energy savings depend on factors such as the building layout, door dimensions, traffic frequency, temperature difference and existing heating or cooling systems.

Thorne & Derrick can help assess the potential energy impact of a high-speed door installation. Contact our team to discuss an energy-saving and return-on-investment assessment for your facility.

Reducing heat loss may also help building designers assess heating requirements for new facilities. Any reduction in heater capacity or operating costs should be calculated for the specific building and operating conditions.
