Abstract: An apparatus for the low energy vaporization of oxidizing agents, such as hydrogen peroxide and peracetic acid, relate to an apparatus comprising a storage tank containing a liquid oxidizing agent or solution, a vaporizer operatively connected to the storage tank for receiving the liquid through a flow control valve and vaporizing the liquid oxidizing agent or solution, a vessel having a vacuum applied thereto with the vessel being operatively connected to the vaporizer so that a vacuum is also applied thereto, and a pressure sensor in said vessel for detecting the partial vapor pressure of the oxidizing agent. A microprocessor is programmed to receive a signal from the vessel pressure sensor and to close the flow control valve upon the vessel reaching a predetermined pressure level so as to prevent condensation of the oxidizing agent and the vessel.
