Reliable Conveying Solutions for ATEX Explosive Atmospheres
What Is ATEX Certification?
ATEX (Atmosphères Explosibles) certification ensures that industrial equipment is safe to operate in environments where flammable dusts, gases, or vapors are present. These EX zones—classified as ATEX zones 1, 2 (gases) and 21, 22 (dust)—are common in industries such as mineral processing, chemicals, fertilizers, biomass, and recycling.
To prevent ignition sources, ATEX certified conveyors must comply with European Directives 2014/34/EU and 1999/92/EC, considering the atmosphere where the machine will operate.
ATEX Screw Conveyors – Safety from the Inside Out
Screw conveyors generate friction and static electricity during operation. For safe operation in ATEX zones, Sinfimasa designs screw conveyors with:
- 3 to 4 grounding points for static discharge.
- Fully conductive and ATEX compliant components, including motor-gear units, seals, and bearings.
- Zone-based safety sensors:
- Zone 22: Rotation and blockage detection.
- Zone 21: Add temperature sensors on bearings and shaft seals to avoid overheating.
These features make our ATEX screw conveyors a reliable solution in hazardous conditions.
ATEX Bucket Elevators – Vertical Lifting, Maximum Protection
Our ATEX bucket elevators are designed with special attention to avoid static build-up and internal ignition:
- Use of antistatic conveyor belts and antistatic plastic buckets.
- Complete electrical grounding.
- Fully ATEX-certified components.
- Safety instrumentation:
- Zone 22: Rotation, blockage, and belt misalignment sensors.
- Zone 21: Added temperature sensors at critical points.
ATEX Chain Conveyors – Robust Solutions for Harsh Environments
Designed for horizontal or inclined transport, our ATEX chain conveyors follow the same rigorous safety standards:
- Static discharge via multiple grounding points.
- Use of only conductive and certified components.
- Zone-specific safety measures, including blockage, misalignment, and temperature sensors.
