What Causes Plugging In Your Ceramic Media Bad?

Regenerative thermal oxidizers utilize a bed of ceramic media that acts as a heat sink, absorbing and giving off heat to an airstream containing VOC’s. This ceramic media is thermally stable and especially suited for regenerative thermal oxidizer use. It's also formulated to have void space throughout the ceramic media bed that offers a path for air to pass through the bed. Some ceramic media is made of loose, smaller pieces that are poured into a bed, while other media is structured, with less void space and smaller airflow paths.

Small void space can be a problem when particulates such as organic material such as fats and oils or high boiling-point solvents build up on the ceramic media. Plugging can occur over time as the void space is filled, reducing the airflow path through the ceramic media. There can even be more sudden changes depending on the materials being filtered. Plugging increases the fan horsepower required to move the air through the media, until the plugging eventually reduces the airflow capacity of the oxidizer.

How do you know if your ceramic media is plugged? We'll give a few tips tomorrow.

Our Customers Say it Best

"We had two catalytic systems in operation when we purchased our first refurbished unit from Kono Kogs. We knew a catalytic system was the way to go, but the availability of a warranty on a used system, and Kono Kogs reputation, helped us make the final decision to buy a used system. The 1985 vintage unit looked great when we received it and it tested out great when we had our stack test (>98% VOC destruction). So when it was time to increase capacity for our other press lines, we did not hesitate to go back to Kono Kogs. They even made our second purchase easier by taking two older systems in trade on a refurbished unit."

"We are very pleased with the performance of the refurbished oxidizer. We greatly exceeded (98%+) our required VOC destruction efficiency and it has performed with >99% up time. The unit looks great as well, which was very important to us!"

"Altering production to avoid high odor days was fine until we were up against a delivery deadline; then the policy was thrown out the window as we strived to satisfy our customers. This was no way to run a business or be a good neighbor- short term or long term. An inexpensive solution from Kono Kogs provided us the flexibility every printer needs."

"After an early actuator failure, this RTO has been running very well. We are pleased with the equipment, cost savings, and with the support provided by Kono Kogs and their OEM partner on this project."

"Kono Kogs really got us out of a bind. We received our rental unit quickly to address our short term emergency. And now we have a more energy efficient system that will actually pay for itself in fuel savings. Kono Kogs provided us support like we would expect from new equipment vendors, but at a lower cost. This system has been installed for over two (2) years and it is still running great."

"We have been running our catalytic system for approximately 9 months and we just recently performed our stack test. Kono Kog's refurbished oxidizer provided 99.9% VOC destruction efficiency, greatly exceed their warranty of 97% and our NJ regulations of 95%. We would highly recommend Kono Kogs."
