We offer a wide range of kiln capacities that cover a wide range of kiln charge dimensions.  A kiln charge can be 40”, 50” or 80” wide. Lengths can be either 17’ or 26’. The height of the kiln charges can be either 42” of 66”.  Every component is carefully selected to match the demands of the kiln charge. This along with perfect control insures that drying schedules are interchangeable among our kilns and our customers.  See our Frequently Asked Questions for general information about how the kilns work.

Interested in serious high quality vacuum kiln dried baseball bat billet production? The VacDry VK2.0 can hold about 2110 Hard Maple or Ash baseball bat billets per kiln charge, dried from green to 6% in about two weeks.

Our most popular kiln is the VacDry VK3.0. The kiln charge is 50” wide x 16.8’ long x 66” high. It is great for the smaller loads of high value 12/4 and 16/4 wood.  With the low load height it is easy to load by hand, making it great for production of squares, dowels, blanks, rounds, and dimensional products.  Other companies are using them to dry baseball bat billets. Still others are drying valuable slabs in less than two weeks off the saw to a sterile and dry 7% moisture content.

Our VK3.5 has become very popular with both the baseball bat companies and lumber companies.

The VK7.0 is our largest standard kiln.  With the proper material handling systems, one of these vacuum kilns can produce as much as 730,000 board feet of 4/4 kiln dried Red Oak lumber per year.  Because it can dry wood so rapidly, it can out-produce conventional kilns that hold tens of thousands of board feet. The vacuum kiln does it in a fraction of the space. Some of our customers have actually installed their vacuum kilns inside the conventional kilns that they replaced.

And since our vacuum kilns are not blowing out heat in an effort to remove water vapor, our drying cost are much lower. And to make the vacuum kiln even more superior, quality is perfect while the kiln operator has no samples to check or adjustments to make. The drying process is automatic.


Parker Converse and his rocking chairs
"...after talking to at least a dozen experts and getting an equal number of conflicting opinions...this will effectively set some new standards in the drying world. I can't imagine why anyone would want to use traditional methods of air drying for several years then kiln drying for several months if vacuum drying can be so effective with such quick turnaround. Thanks again Dennis." - Parker Converse

Steve Farrell at Pacific Rim Tonewoods
"The experiments of drying various species and thicknesses has gone very well. The last load had such a mix of things to be sure I ran a slow ramp. 2" maple slabs, 1" twisted and warped Koa slabs with large crotch sections, 1" fir slabs (with no pitch problems) and fir 4"x4"x8' boards, even some spruce 1" and 1.5" blocks mixed in to shim areas of piles that were mixed thicknesses. Everything turned out great, most amazing was the Koa, color unharmed and flat! Hard to believe if anyone had seen how warped they were going in they would not believe that they were the same boards!" - Steve Farrell, Pacific Rim Tonewoods
