Rosboro Converts To Uniflow CDKs From USNR

Rosboro Co. recently converted four of their double-track kilns to USNR’s patented UniFlow continuous design, exceeding initial production increase goals while keeping emission levels below emission cap requirements. The conversions are part of a larger capital expenditure project expanding Rosboro’s glulam operations.

These conversions are part of a larger project to expand their glulam operation. By converting four of the double-track kilns to continuous kilns, the mill improves energy efficiency with more consistent steam use—a feature of USNR’s UniFlow’s patented approach. The 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. The higher product volume is comprised of fiber that’s straighter, flatter and contains fewer checks and splits.
