Meeting the criteria for ATEX with Quadro^®

Directive 94/9/EC (ATEX 95), and Directive 99/92/EC (ATEX 137) were introduced by the European Parliament and the Council of the European Union in order to protect the lives and health of workers who are using equipment in hazardous areas.

Quadro ATEX Comil^®

When milling potentially explosive products, or milling in a hazardous “zoned” area, special measures must be taken in the design and in the operation of the Comil. Proper bonding and grounding of the mill and mating equipment is essential to minimize static charges. In some cases, level sensors and/or temperature probes are required to monitor the operation of the Comil to prevent ignition. In other cases, when milling products with a low Minimum Ignition Energy (MIE<3 mJ) or low Minimum Ignition Temperature (MIT<300 degrees C), it may be necessary to inert the Comil or use explosion Pressure Shock Resisitant (PSR) construction.

The Quadro Comil is certified for the following ATEX Categories:

• II 2GD IIB T4 (internal and external) suitable for use in a Zone 1, 2, 21, 22 hazardous area.
  
• II 1GD IIB T4 (internal only) suitable for Zone 0, 20 inside of the Comil. (FSA 05 ATEX 1556 X)

Quadro Vac^® ATEX Vacuum Conveyors

When pneumatically conveying potentially explosive bulk materials or conveying in a hazardous "zoned" area, special measures must be taken in the design and operation of the the Quadro Vac. Proper bonding and grounding of the vacuum conveyor and the mating equipment is essential to minimize static charges.   The Quadro Vac is suitable to convey dry products with low Minimum Ignition Energies (MIE>3 mJ).  Conveying hybrid mixtures or discharging into a gas explosive atmosphere is not allowed. 

The Quadro Vac is certified for the following ATEX Categories:

• II 2GD T3 (external) suitable for use in a Zone 1, 2, 21, 22 hazardous area.
  
• II 1D (internal) suitable for Zone 20 inside of the Quadro Vac (FSA 06 ATEX1572 X)

Quadro^® Sifter ATEX

When security screening or sifting potentially explosive products or using the Sifter in a hazardous "zoned" area, special measures must be taken in the design and operation of the Quadro Sifter.   Proper bonding and grounding of the Sifter and the mating equipment is essential to minimize static charges. When sifting products with a low Minimum Ignition Energy MIE<3 mJ) or low Minimum Ignition Temperature (MIT<300 degrees C), it may be necessary to inert the Sifter or use explosion Pressure Shock Resistant (PSR) construction. 

The Quadro Sifter is certified for the following ATEX Categories:

• II 1GD (internal)/ 2GD (external) IIB 200 degrees C (with paddle arm) 135 degrees C (without paddle arm) suitable for use in a Zone 1, 2, 21, 22 hazardous area. Zone 0, 20 inside of the Sifter (FSA 08 ATEX 1584X)
