Hazardous Material Handling

Nitrogen purge hopper:

EHS inerting systems address the hazards of solids addition to process vessels through open ports and manways. The Nitrogen Purge Hopper maintains a low oxygen concentration during the vessel charging process using two key features: a pneumatically powered valve that limits the amount of time the vessel is exposed to ambient air and a full perimeter annular ring that dilutes any incoming ambient air by injecting nitrogen into the product stream.

The EHS Manway Nitrogen Purge Hopper serves as an engineering control to help maintain low oxygen concentrations within a process vessel during the manual addition of solids. This device utilizes a safe, pneumatically opened flap valve that reduces the amount of time the tank is opened to the room environment. A full perimeter annular ring injects nitrogen at dual flow rates to dilute oxygen concentrations in the manway region of the tank. This engineered system has proven to maintain oxygen levels to below 5% for the duration of a charging process.

Fumes containment – The safe way to transfer hazardous liquids:

Key facts:

  • Operator exposure (measured in the breathing zone) is controlled to be less than 0.01ppm.
  • Vapour emission contained to less than 4ppb during the liquid transfer.
  • No physical contact with the hazardous liquid.
  • No physical contact with the contaminated lance.
  • No exposure in the breathing zone when removing the lance from the drum.
  • The use of tool balancers ensure that no manual handling or ergonomic issues.
  • No dip pipe storage problems.
  • More efficient and effective use of ventilation.
  • Suitable for containers ranging from 10 litre to 1000 litre IBCs.
  • Additional containment options available for handling odorous or liquids contaminated with pharmaceutical actives.
  • Available in 316L stainless steel and flouropolymer coated 316L stainless steel e.g. PFA, PVDF, ECTFE.
