Heat Web Offset Printing Catalytic Recuperative Oxidizer in Florida

April 1, 2020

Problem

New press additions required more oxidizer capacity than the existing systems could provide. This heatset printer had two existing oxidizers that were undersized for future needs. They already had experience with catalytic recuperative oxidizers and were very happy with their performance. Due to the high boiling point oils in printing inks, heatset printing is one of the more difficult applications for oxidizers.

Solutions

Improper design can lead to condensing of oils, which can bind components (dampers, sensors, etc.) leading to downtime and, as we have seen, possible replacement of oxidizer systems due to ignition of the condensate. Kono Kogs has extensive experience in the heatset printing industry, so in addition to low cost, refurbished oxidizers, we can provide a pollution control system tailored to a printers specific needs.

For this printer, Kono Kogs provided a refurbished, warranted, catalytic recuperative unit with excess capacity, at a cost of less than 40% of a new unit. The MEGTEC Catalytic units are the top of the line catalytic systems and are specifically designed for heatset web offset printing emission control.

Result

This used catalytic oxidizer met or exceeded all customer demands for this project at a significant cost savings. Within one year this printer added a new press and needed additional pollution control capacity. They purchased a second catalytic oxidizer from Kono Kogs. Their two existing oxidizers were taken in trade on the new system, significantly reducing their investment in the larger catalytic oxidizer. Both catalytic oxidizers have provided superior performance and reliability. Each unit has provided >97% VOC Destruction efficiency.

Unit #2 Before: 5,000 scfm catalytic recuperative oxidizer prior to refurb by Kono Kogs, INC.
