Tailor-Made Mechanical Conveyors for Explosive Atmospheres

17 Jul 2025  |
In industrial environments where combustible dusts or flammable gases are present, safety becomes a central design criterion. These potentially explosive atmospheres—classified under the ATEX Directives (2014/34/EU and 1999/92/EC)—are common in sectors such as mineral processing, chemical production, and the fertilizer industry. In such settings, every piece of conveying equipment must be meticulously designed to avoid becoming an ignition source.

Meeting ATEX requirements involves far more than selecting components off the shelf. It demands a comprehensive engineering approach that considers every aspect of safety, from electrostatic discharge prevention to the correct integration of monitoring systems. At Sinfimasa, we specialize in the design and manufacture of custom bulk material handling equipment—such as screw conveyors, bucket elevators, and chain conveyors—specifically engineered for ATEX-classified zones.

Our approach begins with a detailed analysis of the client’s process and environmental conditions. Based on this, we design systems using conductive materials, individually ATEX-certified components, and appropriate safety instrumentation such as temperature, rotation, and blockage sensors. The goal is not only to comply with the applicable regulations but to offer robust, reliable systems capable of operating safely under demanding conditions.

What sets Sinfimasa apart is our ability to tailor every solution to the unique needs of each plant. From compact installations in confined spaces to large-scale conveying systems for abrasive, corrosive, or fragile materials, we ensure that our equipment integrates seamlessly into existing production lines while maintaining the highest safety standards.

The successful implementation of ATEX-certified systems requires not only regulatory knowledge, but deep expertise in mechanical design, materials selection, and process engineering. At Sinfimasa, these are not just capabilities—they are the foundation of every project we undertake.

Planning an ATEX project? Trust Sinfimasa to deliver certified, reliable, and fully customized bulk handling solutions that prioritize safety, efficiency, and long-term performance.
