Pan Pac installed high temperature processing kiln as experimental facility in February 2012 and has made test development. Then by March next year, it will install German made high temperature kiln with capacity of 80 cubic metres and will start commercial production.
Radiata pine lumber, which is dried by normal kiln to bring moisture content down to about 10%, is retreated by high temperature kiln, which brings temperature to 220-230 Celsius gradually in 36 hours then leave it for three hours. Then the temperature is gradually reduced in 30 hours. Final moisture content will be 6-7%.
TMT is said to be durable with high dimensional stability and preservative treatment is not necessary so it is ideal for exterior use like decking, window frame and siding board. It will be on the market next year with annual production of 9,000 cubic metres.
