Rosboro Company, LLC in Springfield, Oregon, recently converted four of their double-track kilns to USNR's patented UniFlow continuous design. This allowed them to exceed their initial production increase goals while keeping emission levels below emission cap requirements.
These conversions are part of a larger project to expand their glulam operation. By converting just four of their kilns, they were able to increase production by 10-40% and improve energy efficiency with more consistent steam use, the company said.
USNR's UniFlow kilns significantly reduce the risk of sudden and unpredictable fluctuations in steam consumption and reduce demand on the boiler. The higher product volume is comprised of fiber that's straighter, flatter and contains fewer checks and splits.
USNR’s patented UniFlow kiln uses the same automated approach to efficient lumber drying as the Counter-Flow kiln, but with both lumber tracks moving in the same direction instead of opposite directions. This means higher throughput using an existing heat source with no loss of lumber quality.
Founded over 100 years ago, Rosboro is North America’s largest producer of glue-laminated timber.
