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against decades of 'bad press' that poorly engineered vacuum kilns have generated, I have an interest in seeing this outdated and compromised RF/V design get the notoriety I believe it deserves.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.
