Industrial chain manufacturer saves with Nitrex Endoflex S endogas generator system


Nordic Traction Finland recently upgraded its heat-treatment operations by installing a new EndoFlex™ S endothermic gas generator system. Nordic Traction relies on endogas to carburize its traction chains.

Nordic Traction Finland is a manufacturer of traction chains and tracks for forestry and agricultural machinery. The EndoFlex™ S replaced an outdated generator that could not effectively control volume or atmosphere quality and was incapable of scaling up when the demand increased. The new system is also less expensive to operate and mixes to more precise ratios, which helps to maintain a constant furnace atmosphere and consistent gas quality at all times — improving process reliability and the quality of the finished product.

Additional benefits include increased heating efficiency and lower operating and maintenance costs. Because its multi-retort design operates at a lower temperature, the catalyst and retorts last longer, requiring less preventative maintenance. The capabilities of the EndoFlex S were further enhanced by the addition of an AtmoSense™ analyzer, which continuously controls and monitors methane (CH4) to consistently produce the ideal gas mixture for high-quality endothermic gas.

“Nordic Traction was looking for the most sustainable and cost-effective, onsite source of endothermic gas production for their facility in Loimaa,” said Daniel Panny, head of sales at UPC-Marathon, a Nitrex company, in Europe. “Since the EndoFlex S produces only the amount of gas required by the carburizing furnace, there is zero waste in endogas production. This also allows Nordic Traction to save big by maximizing energy usage and gas consumption. I visited the plant six months after the EndoFlex S was commissioned to see how it was working and discovered that Nordic Traction is saving up to 20 percent per month in energy and resource costs.”
