CD Process

cd

process

Similar to all other decontamination methods, CD gas decontamination is a multi-step process. The 5 steps of the CD gas process are pre-condition, condition, injection, exposure, and aeration.

Pre-condition

Raising of relative humidity (RH) levels to between 60-75%.

Condition

Hold time once relative humidity set point has been reached.

Charge

Generation and delivery of chlorine dioxide gas.

Exposure

Hold time once gas concentration set point has been reached.

Aeration

Removal of chlorine dioxide gas from chamber.

Accumulated PPM-HRS

The Exposure step is controlled through an “area under the curve” accrual of gas concentration until a target dosage has been met.

Cycle Progression

Process Advantages:

Safer on materials thanVPHP, bleach, ozone, and liquid chlorine dioxide solutions

Chlorine dioxideis a true gas at ambient temperature

accurate concentration monitoring

size scalable

flexible process
