Oxidation Ovens From Harper International

Harper offers advanced Oxidation Oven technology in order to complement its industry-leading furnaces for carbon fiber processing.

The advanced oven designs are available for tow-bands from 300mm to greater than 4000mm. Harper’s designs include a range of improvements beyond what’s available on the market today, including energy efficient designs.

For the customer, the technology advancements equal more rapid oxidation by eliminating the chimney effect, achieving improved velocity uniformity and range, assurance of temperature uniformity at a variety of flow rates, and optimal control of the reaction ultimately enhancing fiber quality. These improvements come in the form of clearly stated performance guarantees.

The instrumentation improvements of Harper include a two-tier balancing methodology, responsive quench system and rapid cool down system, emissions monitoring, and inherently safer pressure relief system.

Furthermore, Harper’s modular construction design is another advancement that sets these furnaces apart from the competition. The ovens have shown a 90% reduction in labor versus similar field erection times into a full line pilot system (300mm).
