  • Patent number: 12636395
    Abstract: The present invention relates to a system and method for treating air and water in refrigerated spaces using ozone-based disinfection. The system includes an electrolytic ozone generator configured to produce gaseous ozone from water and an air circulation subsystem to create an oxidizing airflow within a housing. The airflow is directed across a titanium dioxide-coated surface to reduce ozone concentration before reentry into the refrigerated space. A controller manages disinfection and purification modes, enabling safe air treatment in environments such as ice machines, walk-in refrigerators, and consumer appliances. In some embodiments, aqueous ozone is also routed to ice makers or water dispensers for waterline disinfection. Optional features include manganese dioxide treatment modules for hydroxyl radical generation, automated door locking during disinfection, and ozone sensors for safety compliance.

  • Patent number: 12636396
    Abstract: The present invention relates to modular ozone-based disinfection systems that generate hydroxyl radicals from gaseous ozone and water vapor using a manganese dioxide treatment module. A sealed, replaceable water cartridge supplies water to an electrochemical ozone generator, producing gaseous ozone for introduction into an airflow path within a housing. An air circulation subsystem directs the ozone-containing airflow across the manganese dioxide treatment module, which catalytically generates hydroxyl radicals and reduces residual ozone to levels safe for human exposure. In some embodiments, a positive temperature coefficient (PTC) heating element preheats airflow to enhance radical production. A controller manages ozone generation, airflow, heating, and operational modes, and may track cartridge usage, transmit data, or enforce geofencing.

  • Publication number: 20260041802
    Abstract: The present invention relates to modular ozone-based disinfection systems that generate hydroxyl radicals (·OH) from ozone and water vapor using a high-temperature catalyst module. The system includes a purification configuration with an air inlet, air circulation subsystem, airflow path, and air outlet, along with a water supply configuration feeding purified water to an electrolytic ozone generator. A catalyst module, such as a PTC heating element, heats ozone-containing air to a hydroxyl radical generation temperature, while a downstream hydroxyl augmentation and ozone reduction module converts residual ozone and conditions the airflow for safe discharge. Embodiments may include a replaceable water cartridge, resin tank, multiple water source options, humidity and purity sensors, and a safety interlock connected to a controller.

  • Publication number: 20250332310
    Abstract: The present invention relates to an air deodorizing system and method that utilizes aqueous ozone as a catalyst to improve air quality by neutralizing odors, and volatile organic compounds (VOCs). The system includes an electrochemical ozone generator that forms aqueous ozone gas and oxygen gas from a water source. A blower creates an airflow extracted from the surrounding environment, combining it with the aqueous ozone gas and oxygen gas to form an oxidized airflow. The oxidized airflow interacts with titanium oxide and manganese dioxide particles, with or without ultraviolet (UV) light, to produce hydroxide molecules that break down pollutants. Residual humid aqueous ozone gas is reduced to a human-safe permissible level, and the deodorized airflow is vented back into the environment. The system may incorporate a dehumidifier to extract water from air, enabling self-sustained operation, and dynamically adjusting blower speed based on ozone concentration, ensuring safety and regulatory compliance.

  • Publication number: 20250332306
    Abstract: A method of treatment using an aqua-ozone hygienization system enables versatile hygienization of items. The method includes placing an item in a tank, generating ozonated concentrate liquid from water via an electrochemical generator, and treating the item with atomized mist or spray using a nozzle. An egress port manages liquid flow, allowing or preventing accumulation in the tank. The system can perform deodorizing mist, disinfecting spray, or immersion treatments, with an ingress port for filling the water reservoir. A platform within the tank adjusts between extended and retracted positions for immersion. The system may include a concave portion for an external nozzle to fill a portable vessel with ozonated concentrate liquid. Additionally, it features a replaceable consumables cartridge, ozone concentration sensors, and a control system with a communication interface and GPS for sending operational status messages to remote resources.

  • Patent number: 12357716
    Abstract: An aqua-ozone hygienization system enables hygienization of items through selectable treatment modes: atomized mist for non-wetting deodorization, spray for wetting disinfection, and immersion for purifying, deodorizing, and disinfecting. The system includes a tank with a platform configured to support items and form a water reservoir below. An electrochemical generator produces ozonated concentrate liquid, while a circulating pump delivers the liquid to a switchable nozzle, enabling misting or spraying. The platform may be stationary or retractable, facilitating immersion by accumulating liquid above the platform or lowering items into the reservoir. Egress ports manage liquid flow, ensuring proper drainage post-treatment. Integrated sensors monitor liquid levels and ozone concentration, while a control system automates operations, offering precise treatment customization.

  • Patent number: 12226538
    Abstract: An aqua-ozone hygienization system is disclosed, including a tank configured to hold an item for treatment. The system enables user selection between three hygienization methods: a non-wetting atomized mist for deodorization, a wetting spray for disinfection, or an immersion for comprehensive purification, deodorization, and disinfection. A platform within the tank forms a water reservoir beneath it and provides a top surface for item placement. The system includes an electrochemical generator that produces ozonated concentrate liquid from water, supplied by a circulating pump drawing from the reservoir. A nozzle connected to the electrochemical generator is switchable between dispensing the ozonated concentrate liquid as either an atomized mist or spray. During operation, the liquid is either misted or sprayed onto the item, or accumulates on the platform to immerse the item, depending on the selected treatment method.

  • Patent number: 12171914
    Abstract: The present invention relates to a system and method of deodorizing air using aqueous ozone as a catalyst. Water is delivered to an electrochemical ozone generator which forms aqueous ozone gas, oxygen gas, and hydrogen gas. The first treatment stage oxidizes airflow extracted from a surrounding environment by combining the airflow with the aqueous ozone gas, oxygen, and hydrogen forming an oxidized airflow. A second stage deodorizes the oxidized airflow to form a deodorized airflow with hydroxide molecules that are created by combining the oxidized airflow with ultraviolet light, titanium oxide particles, and sintered columnar manganese dioxide particles. Residual aqueous ozone gas is converted to oxygen by interaction with the titanium oxide particles and the sintered columnar manganese dioxide particles. The deodorized airflow is vented back to the surrounding environment with ozone gas at or below the human-safe permissible level.
