Thermex-Thermatron Systems is a company steeped in dielectric heating history with its roots beginning in Louisville, Kentucky in the year 1939. Today’s Thermex-Thermatron is the result of a merger between two companies, “Thermex” and “Thermatron”, both pioneers in radio frequency and microwave heating technology.

The first radio frequency (RF) heating system for industrial applications was produced in Louisville, Kentucky by the newly formed Thermal Engineering Company in 1939, later becoming known as the Thermex Corporation. Thermex’s microwave and radio frequency equipment was purchased for use in fabrication, research and development, adhesives, wood-metal bonding, lumber edge bonding, furniture, ceramics, plastics, food, and shoes. Our equipment continues to be used in many of these same applications more than 80 years later.


In 2020, Thermex completed the acquisition of JTE Machines. With this transaction came many new opportunities.  Thermex-Thermatron became the North American and Latin American distributor for FIAB traveling welders, and the North American distributor for Oteman Advanced Technology Cutting Systems. Many of JTE's experienced team members joined forces with Thermex-Thermatron, increasing Thermex's bandwidth in the growing dielectric heating industry.
