Watlow Sensors, Processing and Heaters
1922 -Louis Desloge Sr. founds Watlow Electric Manufacturing Company in St. Louis, Missouri, USA, to manufacture electric heating elements for the shoe industry.
"Through the years, Mr. Desloge promoted electric heat as the new and better alternative to gas heat, which is both hard to control and confine, and steam heating, which is expensive to install and maintain. As our customers' industrial electric heating applications expanded, our engineers responded with innovative new products which soon became industry standards."
