The Mellen Company was founded in 1966 by one man who believed in creating high temperature furnaces that could maximize work time and minimize uncontrolled temperature variations. Mr. Mellen, an avid scientist, combined his years of experience with constant research to develop top-of-the-line products. Today, Mellen combines years of research with computer-aided design and stringent quality control. We strive to provide our customers with well-researched and extensively engineered products. ALL of our products are made in the U.S.A.
