Company History

From our beginning in 1976, Thermal-Flex High Capacity Switch Heating Systems have been subjected to the tough climatic conditions of severe northern winters.  Over the years, thousands of our systems have been built and delivered to U.S., Canadian and European railroads.

Thermal-Flex railroad switch heating products were developed more than 30 years ago out of our effort in research, development and the manufacturing of stress relieving equipment, one of our first industrial heating product lines.  Our stress relieving equipment was widely used for relieving the internal stresses created in massive steel parts such as pipes, valves, boilers, etc. caused by the heat of welding.

Today, Thermal-Flex Systems railroad switch heating products incorporate some of the same materials and design techniques we utilized to develop our stress relieving equipment.  From our initial designs and continued product development, Thermal-Flex Systems is able to offer a wide range of railroad switch heating products, including the only flexible rail heating element.

Designed to withstand the wear and tear of repeated use in harsh environments, our products are used throughout the world by railroads, transit companies, major power facilities, engineering and construction firms, the U.S. Navy and many other manufacturing facilities.

Railroad Experience

The first Thermal-Flex Switch Heating System was installed in November of 1976 on a 30 foot spring switch for the main line of the Central Vermont Railway at White River Junction, Vermont.  This early design was later improved upon with the addition of two crib heaters in the switch rod area.  Further refinements have resulted in the switch heating systems we offer today.

Thermal-Flex products are in use throughout North America and Europe under a diverse range of climatic and operating conditions.
