Piped Ozone Systems for Kitchen Exhaust Ducts and Process Odor Control
Place the ozone generator in an accessible equipment area and deliver ozone gas through tubing to engineered injection points in the duct. This architecture can improve service access and reduce maintenance difficulty in greasy commercial exhaust environments.
Remote generation, controlled gas delivery
Generate
An enclosed ozone tube/module produces ozone from prepared dry air or oxygen with a defined gas outlet.
Transfer
Ozone-resistant tubing carries gas from the generator to one or more designed injection points.
Interlock
The generator operates only with the required exhaust airflow and safety conditions.
Keep the generating element away from the contaminated duct
Kitchen exhaust contains grease, heat and particulates. Placing an exposed ozone plate or open fan-blown tube directly in that environment can increase cleaning difficulty and make service access inconvenient. A piped-output system allows the ozone source and power electronics to be located in a cleaner, accessible area while only the delivery line and injection hardware enter the duct.
This generally requires more initial hardware—generator enclosure, feed-gas preparation or oxygen supply, tubing, injection points, controls and interlocks. For suitable installations, the higher initial cost can be offset by easier maintenance, more controllable gas delivery and reduced exposure of the generator to grease.
Oxygen feed supports cleaner, more consistent ozone gas
Open ozone plates and fan-blown tubes normally use surrounding air. Nitrogen and moisture in that air can affect performance and contribute to nitrogen-oxide by-products in electrical-discharge ozone generation. An enclosed piped-output generator can use prepared dry air or oxygen. Oxygen feed minimizes nitrogen entering the discharge cell, which can help reduce NOx formation and normally supports higher ozone concentration.
Data required before selecting output and injection points
| Input | Why it matters |
|---|---|
| Duct dimensions and layout | Defines volume, residence distance and injection locations. |
| Exhaust airflow and schedule | Determines dilution, operating duty and interlock logic. |
| Odor and process source | Grease loading, cooking process or industrial contaminant affects design and maintenance. |
| Ozone concentration and gas flow | Must be selected separately from nominal g/h output. |
| Feed gas | Prepared dry air or oxygen affects concentration, consistency and NOx risk. |
| Tubing distance and back pressure | Affects gas delivery and final outlet performance. |
| Occupied areas and discharge point | Determines monitoring, controls and exposure safeguards. |
Commercial and OEM projects
Commercial kitchens
Odor-control systems integrated with exhaust airflow and service procedures.
Food-processing exhaust
Controlled duct injection subject to process validation, material compatibility and local requirements.
OEM odor-control equipment
Custom generator modules, controls, voltage, enclosure, tubing and private-label configurations.
Built around actual airflow and service conditions
Morhon Tech was established in 2015, with ozone-industry experience dating to 2007. We work with equipment manufacturers, project companies, distributors and overseas ozone-industry partners. The final installation must be designed and approved for the actual duct, exhaust, occupancy and destination-market requirements.
