"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."
