Making a Difference in Sawmills

Matrix improves drying consistency and throughput

Sawmills benefit greatly from Matrix’s steam expertise

Beginning in 2003, Matrix began creating breakthrough results for sawmills, including Hampton Affiliates (WA State) (refer to case studies – Hampton Affiliates). Since then, 37 sawmills have experienced optimization services provided by Matrix Northwest.  The average reported improvement in charge time is an impressive 10%!

Matrix has successfully worked with a wide variety of sawmills producing dimensional lumber, shop, specialty, softwood, hardwood.  Whether you use low pressure or high pressure, or your drying schedules vary greatly, Matrix has developed specialized knowledge enabling us to assist our clients to create maximum results and a fast return on investment.

Boise Cascade

In March of 2004, Matrix worked with Boise Cascade. Within six months Boise was so impressed with the results achieved, they signed deals to begin work on their other sawmills at Kettle Falls, WA and Elgin, OR. The return on investment at Boise was less than 6 months!

Interfor - Beaver, Washington

Matrix worked with the Portac Beaver WA sawmill in December 2004. As reported by Ken Welever, Interfor Lead Boiler Man in 2012, the plant experienced a 50% drop in water usage,  eliminated cold zones in the kilns and reduced charge times about 10%. Additionally, Matrix installed permanent condensate removal components that have eliminated the need for ongoing expense and maintenance at substantial savings.

F H Stoltze Land and Lumber Co - Columbia Falls, Montana

F H Stoltze converted all four kilns between April 29 and August 23 in 2005. As they installed the kilns to Matrix venturis one at a time the benefits overall improved.

William Woods, Kiln Supervisor reported, “Your Matrix (venturi) product has been outstanding in performance in our dry kilns. I have operated our kilns for 20 years. We replaced our bucket traps after a lot of research and phone calls from references and mills that have them in operation.”

F H Stoltze report April 3, 2008 after four years of service with venturis:

  • With their four zone-controlled kilns they have seen the elimination of wet pockets and more uniform drying.
  • They have seen an improvement in drying times as much as 15-20 hours, depending on wood species.
  • They have more control over the kilns and the boilers don’t struggle to keep up with the kiln steam demand.
  • Kilns warm up faster and the kiln schedules are not as harsh as they were.
  • Their lumber now looks great and has less degrade, tighter moisture content and standard deviation.
  • Their grade inspector is very pleased with their lumber.

William Woods, “It was a pleasure to work with your field technician to make sure everything is working properly, your company made the necessary changes to our system to make it function and get the most efficiency. Thank you Matrix for your concerns and improvements you have made at our plant, I would recommend this to any plant for replacement.”

Jeld-Wen Windows & Doors - Bend, Oregon

JELD-WEN converted all 13 of their kilns in their Bend OR plant to Matrix venturis by the end of December, 2005.

Client reported on June 28th, 2006:

All orifices [Matrix venturis] were installed and all kilns operating.

Before conversion: They had numerous kilns with mechanical traps that were failing. The traps were installed in locations inside the kilns making them almost impossible to troubleshoot and maintain. They were constantly having to extend kiln schedules due to insufficient kiln temperature due to trap failure.

After conversion to Matrix venturis: These problems disappeared. They have had a solid six months of operation with all 13 kilns without a single related occurrence.

Dan Larwin, “I look forward to the continued performance for many more years.”
