STERIS’ VHP 1000ED provides a safe, environmentally friendly method to decontaminate sealed enclosures up to 10,000ft3. STERIS VHP 1000ED Mobile Biodecontamination System utilizes Vaprox Sterilant (EPA Reg. No. 58779-4) as a means of achieving dry, low temperature sterilization within large sealed enclosures such as cleanrooms and filling lines. The dry, gaseous process consists of four distinct phases: Dehumidification, Conditioning, Biodecontamination and Aeration. Aeration continues until hydrogen peroxide is reduced to an acceptable level and the room is commissioned for regular use.
