Rail Element Insulated Channel

Thermal-Flex Rail Element Insulated Channel is an integral part of our switch heating systems. First introduced to the railroad switch heating industry in 1976 as an energy savings concept, our insulated channel helps to increase rail temperatures by as much as 40% versus non-insulated rail elements. Thermal-Flex insulated channel is available in different sizes and materials to meet a range of rail configurations and trackside environmental conditions.

Our high density insulated channel is designed to surround the rail heating element at the rails webbing. The channel geometry is optimized to drive the rail element heat into the rail instead of it being lost to the environment as in non-insulated systems. Utilizing this design, an insulated rail element can often be operated at a lower wattage resulting in reduced operating costs. The insulated channel is easily held in place with spring steel track clips simplifying installations.
