New Zealand Sustainable Forest Products LP of Reefton, New Zealand had a lightly used VacDry 1.25m they'd originally acquired for research and development before expanding to four VacDry 4.0m vacuum kilns.  This kiln has sold and is no longer available.

"Just wanted to thank you all for your input on drying my burl. At this point I don't feel as though I could have found two more knowledgeable people than Dennis and Garrett Socling. Garrett sent me a few photos after a week in the "chamber" and the degrade appears to be non existent or minimal at best. Gotta love this technology. I can't wait to see the finished product. If it holds together (and I expect it will) this process will stand as a real milestone in drying technology. Not that I know much about drying but after talking to at least a dozen experts and getting an equal number of conflicting opinions, if we are successful, 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, Parker Converse Custom Rocking Chairs

Chinese-built radio frequency vacuum (RF/V) wood dry kilns

by Dennis Socling

Let me state up front that I have never operated a Chinese-built RF/V kiln, but I used to be responsible for the operation of eight 5000 boardfoot American-built PowerDry RF/V kilns in the early 1980s.  As the president of PCS VacDry and having to fight against decades of 'bad press' that poorly engineered vacuum kilns have generated, I have an interest in seeing this outdated and compromised RF/V design get the notoriety I believe it deserves.

I have come across two companies in North America who have recently purchased Chinese-built radio frequency vacuum kilns because of the Chinese claims that they are great kilns, combined with a ridiculously low price. After a discussion with one of our potential customers in Australia and discovering they had decided to buy the Chinese RF/V kiln, I decided it was time to set the record straight: substantial compromises were made to reach a price point

We've recently revamped and expanded our VacDry vacuum kiln lineup.  During this process, we realized that our old model naming convention was becoming increasingly convoluted and was not particularly intuitive.  We've gone through and attempted (feedback is always appreciated!) to standardize things such that when looking at a VacDry VK#.# model designation, the basic characteristics are more obvious.
