Decontamination Chamber Atmospheric
Ensure reliable, high-level surface biodecontamination of pre-sterilized material packages to support contamination control in cleanroom material transfer.
A typical application is surface bio-decontamination of pre-sterilized material packages, such as vial stopper bags, wrapped components and syringes.
• STERIS’s non-condensing vaporized hydrogen peroxide VHPTM process for 6-log reduction of bioburden.
• Short cycle time with a proven decontamination result throughout the chamber.
• A unique process for reducing particulates on transferred materials.
• The DC-A is completely independent of a building HVAC system.
A turn-key solution that is easy to install and validate.
• Optional particle monitoring and control system available.
DC-A Three-Phase Process Cycle
Pre-Conditioning
During the pre-conditioning phase, both the chamber and the load are flushed with a strong airflow. The air is circulated through a dryer unit and HEPA filter in a closed loop configuration to enable reduction in both particulate load and chamber humidity.
With an optional particulate monitoring and control system, the reduction of particulates inside the chamber is measured with a sensor placed in the air channel before the HEPA filter. The HEPA filter integrity can be continuously monitored by an optional on-line measurement.
VHP Decontamination
In the VHP Decontamination step the aqueous hydrogen peroxide solution is flash-vaporized and dispersed into the airstream. Inside the chamber, Vaporized Hydrogen Peroxide (VHPTM) gas is circulated by the fan, ensuring even distribution of the gas.
Post-Conditioning
During the Post-conditioning phase, the load is aerated by circulating VHP and air mixture through the catalyzer to remove the peroxide from the load and chamber.
