• Pre-Condition

    Raising of relative humidity levels to between 60-75%.
    Increased humidity levels are necessary for all spore reduction.

  • Condition

    Hold time once relative humidity set point has been reached. This is to allow spores to swell and crack due to humidity prior to gas introduction.

  • Charge

    Generation and delivery of chlorine dioxide gas.


  • Exposure

    Hold time once chlorine dioxide gas concentration set point has been reached.


  • Aeration

    Removal of chlorine dioxide gas from chamber.

  • Safer on materials

    Safer on materials than VPHP, bleach, ozone, and liquid chlorine dioxide solutions.

  • Safest decontamination method

    Safest decontamination method among gaseous and vaporous methods.

    • Non-Carcinogenic.
    • Non-flammable at use concentrations.
    • Non-explosive, no need for Damage Limiting Construction (DLC).
    • No measurable residuals.
  • Chlorine dioxide is a true gas at ambient temperature

    • Complete distribution as chlorine dioxide is governed by gas laws.
    • Quicker Aeration as CD does not condense onto materials.
  • Chlorine dioxide gas concentration

    Chlorine dioxide gas concentration can be accurately monitored throughout the cycle.

    • VPHP cannot be accurately monitored as concentration is not uniform throughout area due to condensation and distribution gradients.
  • Decontamination volumes

    Able to completely decontaminate volumes over 1 million ft3 with multiple generators.

  • Chlorine dioxide gas has a very flexible process

    • Effective at low concentrations.
    • Effective over wide temperature range.
    • Effective under ambient or vacuum pressures.
    • Effective against a wide range of organisms.
