Help us celebrate our 50th year in business! 

1969

Founded in 1969 as a manufacturer of industrial ovens, Otto Andreae and Rusty Sherman brought their up-start business to Door County, Wisconsin and began fabricating in an old apple warehouse. Brad Andreae, Otto’s son, jumped in to assist his father, working around the clock during his college breaks, and then full time after graduation, to get the business off the ground.

The name “Therma-Tron-X, Inc.” was selected for three reasons.  The word “Therma” stands for thermal, regarding the oven aspect of the company.  The word “Tron” comes from the word “Electron” for the electrical and ecoat portion of our systems, and “X” because, at that time, no company they knew of with an “X” in their name had ever failed.
