Overview
The Manusa high-speed roll-up door for ATEX areas compartmentalises explosive atmospheres up to Type II 2G where flammable gases, vapours or combustible dusts are handled. It is designed to isolate hazardous zones using an ATEX-rated motor to eliminate electrical ignition sources and an anti-static safety fabric. The product includes a set of safety devices specific to ATEX environments and can be configured to suit different opening sizes and project requirements.

Applications

• Sectioning and containment of potentially explosive atmospheres (ATEX zones) up to Type II 2G.
• Industrial environments handling flammable gases, vapours or combustible dusts.
• Suitable for indoor and outdoor installations depending on configuration.

Key features and safety systems

• ATEX-rated motor to eliminate electrical spark risks in explosive atmospheres.
• Anti-static safety fabric to reduce electrostatic build-up.
• Integrated safety photocell in the side guide for obstacle detection.
• Lower-edge sensor strip: if an obstacle is detected the door raises and will not descend until clear.
• Designed to compartmentalise explosive atmospheres up to Type II 2G.

Optional equipment

• Motor cover.
• Silk-screening (custom printing) on the fabric.
• Alternative activation/opening systems: radar, presence sensors, ceiling handles, magnetic contacts.
• Custom coloured or silk-screened fabric options.

Colors

• RAL 1018
• RAL 7038
• RAL 5010

• RAL 2004

Peepholes

• Shapes: square and rectangular.
• Positions: horizontal and vertical.
• Options: multiple peepholes can be provided.

Frequently asked questions (selected)

• What is an ‘ATEX area’? An ATEX area is an environment where gases or dust in the atmosphere may create an explosive atmosphere. Materials used in some production processes can generate explosive atmospheres; doors for these areas must include anti-static fabrics, ATEX-rated motors and control components that eliminate electrical ignition sources.
• What safety mechanisms does the door for ATEX areas feature? Safety mechanisms include an integrated safety photocell in the side guide and a lower-edge sensor strip which, on detecting an obstacle, raises the door and prevents it from descending until the area is clear.
• What is an explosive atmosphere? An explosive atmosphere is present when flammable gas, vapour, mist or dust mixes with air and, after ignition, combustion spreads through the unburnt mixture. This ATEX door is designed to section off explosive atmospheres up to Type II 2G.
