ODS-3H Buyer's FAQ
Q.What is the discharge temperature?
A.The discharge temperature will be a maximum of 20-deg F above incoming gas temperature. There is a heater band on the top of the unit that slightly increases the temperature along with minimal exothermic reactions in the destruct media.
Q.Does the ozone destruct unit require maintenance?
A.With clean air/ozone going into the unit and no other volatile gas vapors, the catalyst will last 3-4 years before requiring replacement. This is the only maintenance required. Catalyst cost is $25/lb.
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.10% 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.
Q.Can the unit be recharged if water condenses on the catalyst?
A.Yes. Recharging is possible. The media must be removed and baked at 200-deg for 1 hour. The media will not be back to manufactured performance. Expect a performance reduction of 25%.
Q.How does humidity affect the output?
A.No. Humidity has no effect on the performance of the ozone destruct unit as long as water does not condense 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 move in either direction on the ozone destruct unit.
Q.How often should destruct media be replaced?
A.Under most conditions, destruct media should be replaced after three years. However, media that has been contaminated or poisoned by water, organics, VOCs, ordust will need to be immediately replaced. Media that has been crushed will have reduced performance and should also be replaced.
Q.What is the surface temperature of an ODS-3H when operated?
A.With gas flowing through it and the heater band turned on: < 130° F
Q.Will I get a tracking number when my item ships?
A.For customers who chose [b]UPS[/b]: a tracking number is automatically sent via e-mail before the order leaves our warehouse. For customers who chose [b]FedEx[/b]: a tracking number is usually available if requested by either e-mail or phone.
