Clean Stream Afterburner systems come in 2 versions, Catalytic and Thermal Oxidizers. Our highly efficient Catalytic Oxidizers rely on small burner and integrated catalyst module to operate effectively at only 750 F.
Thermal Oxidizers, on the other hand, rely on a larger burner and very high temperatures of 1200-1400 F to operate optimally. Both versions come in various sizes to accommodate all size roasters. The larger the roaster's exhaust flow rate, the larger the afterburner typically needs to be.
Most often, only the "roast air" is treated, which is the exhaust coming directly from the roaster drum. The cooling rack exhaust is not typically treated by an afterburner unless it's required by your local air quality management district. Please contact us for more details and we'll outline the right size clean Stream Afterburner to suit your roastery needs.

Catalytic Oxidizer Systems
Clean Stream Afterburners drastically reduce Smoke, Odor, Fine Particulate, CO and VOC created during the coffee roasting process.
Our most fuel-efficient Clean Streams are considered "Catalytic Oxidizers" because they use a small gas burner and a "catalyst module" to facilitate the break-down of exhaust pollutants. They typically achieve a 95% destruction efficiency at only 750 F.
The low operating temperature means they use substantially less fuel than standard afterburners which operate at around 1300 F, making the Clean Stream substantially less expensive to operate.
All Clean Streams have multiple safeties and feature UL, CE and CUL listed components. Clean Stream Afterburners offer the perfect blend of modern aesthetics, efficiency and functionality.
The Catalyst Module
All Clean Stream Afterburner "catalytic oxidizer" systems have a removable catalyst module (bottom left). The catalyst facilitates the break down of smoke, odor, VOC and CO at only 750 F.
Our catalytic oxidizers come standard with a catalyst module which typically achieves 95% destruction efficiency, but can be upgraded to achieve 98%.
Catalyst Maintenance
Over time, chaff and residue may accumulate on the catalyst, which will require cleaning with compressed air or a shop-vac with brush attachment. To remove the catalyst, simply unlatch the curved access door located towards the top of the afterburner, remove the insulated "cover block", and slide out the "catalyst module". It's that easy!
The Control Panel
All Clean Stream Afterburner "catalytic oxidizer" systems have a sleek Hoffman control panel. The centerpiece of the panel is a high quality Honeywell UDC1200 temperature controller, which is the brain of the whole system. It will read the current temperature inside the afterburner and automatically adjust the burner output as needed, keeping the system right around 750 F at all times. Also standard are a "main power" switch, "burner on/off" illuminated push buttons, and a Mini-helic gauge to measure back-pressure.
