Dustmech 2D/3D

When an application carries a risk of dust and vapours, Pyroban offer a passive solution for diesel materials handling equipment. Our Dustmech 2D/3D technology protects diesel mobile equipment operating in Zone 21 and Zone 22 ATEX certified areas.

The Dustmech 2D/3D conversion allows you to continue your operation as normal, safe in the knowledge that you are protected from any potential explosion risk. For areas which carry an ATEX Zone 22 classification and may also carry a gas risk, Dustmech can often be combined with system6000 gas detection.

Dust carries a different set of risks to gas applications, and our engineers will assess the application based on the following criteria:

Is it Conductive or Combustible? Flour, cocoa, coffee, milk, corn-starch, polymers, talcum powder, custard, sugar and paper fibres are all combustible. However carbon black, aluminium and other metals are likely to be conductive dusts and require additional precautions.

What is the Ignition temperature? Cloud (C) and Layer (L)
Dust Cloud and Dust layers Ignite when in contact with hot surfaces. Materials handling equipment component temperatures must be limited to ensure their surface temperature cannot become a potential ignition source.

The Dustmech 2D/3D conversion is a passive system without any active shut down technology – it will warn the operator if a dust or vapour is detected, but it is designed to continue operation safely.

The Pyroban Dustmech 2D/3D conversion typically includes the following:

  • Explosion proof Exd enclosures for arcing and sparking components
  • Surface temperature limitation to ensure the engine, motors, brakes, electrics and other components remain below the auto-ignition temperatures (T Class) of flammable materials
  • Inlet shutdown valve for automatic and manual shutdown
  • Water cooled exhaust gas cooler to limit surface and exhaust temperatures
  • Frame leakage monitoring
  • Exe components
  • Exi intrinsically safe circuits
  • Exm encapsulation
  • Exe battery
  • Cladding of forks
  • Anti-static seat cover for 2D applications
