DuPont licenses BTU its catalytic oxidation tech for solar manufacturing

BTU International (Nasdaq: BTUI) will integrate DuPont Packaging Graphics’ catalytic oxidation technology into Tritan metallization firing systems. The technology was developed for abatement of VOCs, originally in DuPont flexographic printing systems, and conserves energy compared to thermal oxidation.

February 11, 2011 – BUSINESS WIRE — BTU International Inc. (Nasdaq: BTUI), advanced thermal processing equipment and process supplier, signed a worldwide licensing agreement with DuPont Packaging Graphics (DuPont) for the use of catalytic oxidation technology in solar cell fab equipment. Developed by DuPont Packaging Graphics for the abatement of volatile organic compounds (VOCs), the technology is more energy-efficient than competing thermal oxidation processes, enabling lower manufacturing costs. It will be integrated into the BTU Tritan metallization firing system.

“Catalytic oxidation of VOCs promises to use dramatically less power than traditional thermal oxidation. Not only does this impact the tool’s overall cost of ownership and therefore cost per watt, but it also is a more responsible way for our solar customers to manage their effluent,” said Jan-Paul van Maaren, Ph. D., vice president of marketing at BTU.

“The catalytic oxidation technology was developed for DuPont flexographic printing systems…with nearly 150 units installed,” said Dalen Keys, global technology manager, DuPont Packaging Graphics. “We are very pleased to leverage the technology to benefit BTU and the solar energy industry.”

BTU International is a global supplier of advanced thermal processing equipment and processes to the alternative energy and electronics assembly markets. Information about BTU International is available at
