Abstract:
A hydrogen peroxide sterilization system comprising:(a) a plurality of vaporizers which independently inject vaporized hydrogen peroxide into a carrier gas at differently adjustable rates, each vaporizer including a separate liquid hydrogen peroxide regulator for simultaneously, variably, and independently controlling a rate of injection of hydrogen peroxide into the vaporizer;(b) a carrier gas supply for supplying a flow of the carrier gas to the vaporizers;(c) at least one supply line for transporting the hydrogen peroxide vapor and the carrier gas from each vaporizer to different regions of an enclosure to be sterilized; anda control system for controlling each of the vaporizers to adjust independently the rate at which each vaporizer injects vaporized hydrogen peroxide into the carrier gas so as to provide each of the regions with a selected concentration of hydrogen peroxide vapor.
