ODS-3 Buyer's FAQ
Q.Is the ozone destruct unit vacuum compatible?
A.Yes. We use FNPT connections with Teflon tape & paste on the unit and they do seal very well. You might have to add Teflon tape and Teflon paste on your connection to our ODS unit but are confident you can get it to work in a vacuum environment. If the customer desires, we can also weld special vacuum fittings on to the unit.
Q.What gases can poison the catalyst?
A.Sulfur Compounds, Halogenated Compounds, Hydrocarbons, Heavy Metals, NOx, and Silica. Once the catalyst is poisoned, it must be replaced - it cannot be recharged.
Q.What is the maximum inlet ozone concentration that will result in an outlet concentration of 0.10 PPM or less.
A.1% ozone concentration by wt. is the maximum inlet O3 level of the ozone destruct unit to maintain 0.10 PPM or less on the output. Higher ozone concentrations result in a specially designed unit. Slower flowrates at higher ozone concentrations can also result in ozone concentrations less than 0.10 PPM.
Q.Can the unit be recharged if water condenses on the catalyst?
A.The ODS-series should not be used with moist, or humid gas streams. If moisture does poison the catalyst the catalyst can be replaced. For humid air streams the ODS-H series should be used
Q.How does humidity affect the output?
A.The ODS-1 will have a diminished ozone destruct efficiency and may fail due to condensation on the catalyst.
Q.What are the by-products of the ozone destruct unit?
A.Oxygen and a minimal amount of heat are the only by-products. The catalyst does not give off any residue during ozone destruction.
Q.Can air move both directions in the ozone destruct unit?
A.Yes, air can flow both directions through the ODS-series.
Q.How often should destruct media be replaced?
A.Destruct media should be replaced annually for best performance.
Q.Will I get a tracking number when my item ships?
A.For customers who chose UPS: a tracking number is automatically sent via e-mail before the order leaves our warehouse. For customers who chose FedEx: a tracking number is usually available if requested by either e-mail or phone. For customers who chose USPS: tracking numbers are only created by USPS for select services, such as insured packages. We will be happy to provide available tracking information if requested.
