Abstract: Ozone laundry systems and related methods are shown and described. In one embodiment, an ozone laundry system includes a washing machine; an ozone generator, a Venturi-injector, a secondary injection device, and an ozone control system (OCS). The washing machine may have a vented drum for holding laundry and a liquid wash bath, and include a plurality of operational configurations. The OCS may be configured to provide ozone to the Venturi-injector when the washing machine is in the fill configuration, and provide ozone to the secondary injection device when the washing machine is in the wash configuration. The result is a system that is able to maintain ozone at a high level for a duration.

Abstract: Systems, devices and methods for controlling ozone output are shown and described. In one example, the disclosure is directed to an ozone output system for supplying ozone to at least one of a plurality of devices that demand ozone. The system may comprise an ozone generator arranged to provide ozone to at least one device, a pulse density modulation output, an inverter-based power delivery (IBPD) circuit, and an output control circuit (OCC).

Abstract: An open-loop ozone washing system for safely washing with high levels of ozone is shown and described. In one embodiment, the system includes at least one washer having a drain in fluid communication with a sewer. The system also includes an ozone source, which is preferably an ozone generator. The system also includes an off-gas control system operably connected to at least one washer. Using such a configuration, the washer can safely wash with a liquid wash bath having about 2 ppm to about 20 ppm ozone. The present invention also includes kits and methods for converting traditional washing machines to open-loop ozone washing machines.
