Emergency Thermal Oxidizer Fabrication

February 10, 2022


An oil recycler had a failing thermal oxidizer. The internally insulated shell was deteriorating and near failure. Since the sub-systems such as fans, gas train, controls, and dampers were functioning well, a shell-only replacement was the least disruptive option. Lead time was a major concern due to unknown life-expectancy of the shell and the uncertain availability of metal during the 2021 supply chain challenges.

Kono Kogs was entrusted to fabricate, insulate and ship the replacement shell as quickly as possible, in hopes of a 6-8 week delivery. Steel and material needed for the shell manufacturing were secured prior to asking our customer to commit to the purchase. With the significant fabrication capability added at Kono Kogs since early 2021, including many modern forming and cutting machines and the great can-do attitude of our fabrication team, Kono Kogs was confident of success. We are grateful this first-time customer was willing to give us their trust.

The thermal oxidizer shell was ready to ship in under 6 weeks. This was a significant achievement considering the limited drawing availability for this older system, and the 2021 supply chain challenges.
