ATEX DSEAR Dust Extractors Explosion Relief

We ensure all our equipment conforms to Health and Safety Executive legislation, ‘DSEAR’ (Dangerous Substances and Explosive Atmospheres Regulations 2002), which came into force on 9 December 2002.

Our ATEX dust collectors are designed for specific dust/fume types and explosive properties. Many factors are taken into account, such as:

  • Explosive properties of dust, Kst, Pmax, Pred, lower explosive limits etc.
  • Calculations are performed to check vessel strength, explosion relief size.
  • A hazardous Area Classification exercise is done to confirm zoning in / around dust collector, ducting, LEV hoods and capture areas.
  • Correct ATEX category equipment is specified for particular areas and zones.
  • Discharge / bin design including rotary valves.

Our scope of supply can include;

  • Certified and batch tested explosion panel(s) that are sized and positioned as per ATEX (VDI) guidelines.
  • Anti-sparking features for main fan and Ex II 3D shaker and Fan motors
  • Atex Terminal box wire with (SWA) cable
  • ATEX back-draught and explosion break valves.
  • Antistatic flexible ducting and Antistatic filters.
  • ATEX rotary valves providing explosion break between collector and discharge point.
  • Grounding of the filters to the dust collector body, and Grounding of the dust collector.
  • ATEX air flow monitoring systems to confirm system performance and help ensure area zoning is effective.
  • A manual outlining maintenance and operating guidelines with explosion risks in mind.
  • During commissioning we will carry out a risk assessment of our system and ensure the adequacy of explosion control measures put into place.

We can provide specific DSEAR training for employees and maintenance staff regarding the maintenance and operation of the dust collector and all other ATEX issues.

We can design/supply/install airflow control and monitoring / alarming systems for use in potentially explosive atmospheres. This includes supply of ATEX pressure, flow sensors and systems requiring duty/standby, battery backup or supervisory control systems.
