Product overview
Every ozone installation produces more ozone than the process consumes. Whatever is left in the off-gas from a contact tank, reaction vessel or generator vent has to be removed before that gas reaches the atmosphere or the plantroom. The component that does this work is the ozone destructor, and the working part of a destructor is the catalyst bed inside it. This product is the media that fills that bed.
The media is a mixed metal oxide catalyst formed into hard pellets. Ozone-bearing gas is drawn through the packed bed, and at the pellet surface the unstable ozone molecule (O₃) is split and recombined into ordinary molecular oxygen (O₂). No reagent is dosed, nothing is scrubbed into a liquid stream, and the outlet gas is simply air with the ozone residual removed. Because the pellets catalyse the reaction rather than react with the ozone, they are not consumed by throughput — activity is lost gradually through moisture, dust, oil mist and process contamination coating the active surface, which is why destruct beds are recharged on condition rather than on a fixed chemical dosing schedule.
Ozone has a low workplace exposure limit and is corrosive to seals, elastomers and electrical assemblies. A destruct bed that has lost activity shows up as rising ozone readings at the vent, alarms on ambient ozone monitors, complaints of a sharp smell around the plantroom, and accelerated wear on downstream ductwork. Recharging the bed with fresh catalyst media restores compliance and protects both the operators and the plant, at a fraction of the cost of replacing the destructor vessel or shutting the ozone stage down.
This is a compatible replacement catalyst intended for destructors that were originally charged with an industrial ozone catalyst of this class — the type commonly referred to on site as Carulite. It is not a Carulite-branded product and is not manufactured by Carulite. Before we quote, we check the destructor make, bed volume and pellet size so the charge you receive suits the vessel you are refilling.
The media is held in Australian stock and despatched from Australia in 20kg quantities, Australia-wide and internationally. That matters on ozone plant: destruct media is usually needed at short notice during a shutdown window, and local stock removes the wait associated with overseas manufacturing and consolidation.
Features
The media converts ozone back to oxygen by catalysis. It is not consumed in the reaction, so service life is governed by contamination and moisture exposure rather than throughput alone.
Supplied as free-flowing pellets sized for packed catalytic beds, giving a high active surface area with a low, predictable pressure drop across the destruct vessel.
Works in both ambient catalytic destructors and thermal-catalytic units where an upstream heater is used to hold the gas stream below the dew point.
Each order is supplied as a sealed 20kg quantity, which keeps the media dry in transit and in store until the destruct vessel is opened for a media change.
Selected and supplied by engineers who commission and maintain industrial ozone plant, so bed sizing, changeout intervals and vessel fitment are reviewed before you order.
Held in Australia and despatched worldwide, so plants outside Australia are not held up waiting on an overseas manufacturing slot.
Applications
Ozone destruct catalyst media is used wherever an ozone-bearing gas stream is vented. The duties below cover the majority of installations we supply and maintain.
Destruction of residual ozone in the off-gas from contact tanks and dissolved-ozone contactors at drinking water plants, so vent gas can be discharged safely.
Off-gas treatment on ozonation stages used for disinfection, colour removal, odour control and micropollutant oxidation at municipal and industrial treatment plants.
Vent-gas destructors fitted to ozone generators, reaction vessels, storage tanks and plantroom extraction systems where the exhaust must be free of ozone.
Ozone oxidation duties in chemical, pharmaceutical and specialty manufacturing where reactor off-gas is scrubbed before it reaches the atmosphere.
Corona and plasma surface treaters used on film, foil and extrusion lines, where the extraction duct carries ozone generated at the treatment station.
General emission-control duties on food and beverage, mining, aquaculture and laboratory installations subject to workplace ozone exposure limits.
Technical information
Values below describe the product as supplied. Bed volume, pellet size and charge quantity are confirmed against your destructor before despatch.
Shipping
Orders are despatched from Australian stock. Domestic consignments move by road and air freight to metropolitan and regional sites Australia-wide, including remote mining and water authority locations.
International orders are despatched worldwide. Freight is quoted with the order based on destination, service level and the number of 20kg units required, and we prepare the commercial and export documentation the consignment needs.
The media is supplied sealed for transport. Keep it sealed and dry in store until the destruct vessel is opened for the media change — moisture uptake before installation reduces catalytic activity.
FAQ
Ozone destruct catalyst media is a pelletised mixed metal oxide catalyst packed into the bed of an ozone destructor. As ozone-bearing gas passes through the bed, the catalyst breaks the ozone molecule down into ordinary oxygen at low temperature, so the vent gas leaving the destructor no longer carries an ozone residual. Because the reaction is catalytic, the media is not consumed by the ozone itself.
This product is not manufactured by Carulite and is not a Carulite-branded product. Many technicians use the word "Carulite" as shorthand for any ozone destruction catalyst, and this media is offered as a compatible alternative for destructors originally charged with that type of catalyst. We confirm bed volume, pellet size and vessel arrangement against your unit before supply so the replacement charge suits your destructor.
Potable water and wastewater treatment authorities, food and beverage processing, mining and minerals, aquaculture, chemical and pharmaceutical manufacturing, and manufacturers running corona or plasma surface-treatment lines. Any plant that generates or doses ozone and vents the off-gas needs a working destruct bed.
Service life depends on the duty rather than a fixed interval. Dry, clean gas streams give long life, while moisture carry-over, oil mist, dust and process contaminants coat the pellets and reduce activity. Most plants schedule a media change when destruct outlet ozone readings begin to climb or pressure drop across the bed increases. We can review your operating data and recommend a changeout interval.
Yes. The media is held in Australian stock and despatched Australia-wide and worldwide. Freight is quoted with the order based on destination and the number of 20kg units required, and export documentation is prepared for international consignments.
The required charge is set by the bed volume of your destruct vessel and the gas flow it treats. Send the destructor make and model, or the internal dimensions of the catalyst bed, and we will confirm how many 20kg units your changeout requires before you commit to an order.
