Thermal-Flex Spiral Fluted Flexible Rail Heaters offer a solution to installations where switch components have not been configured for rigid rail heater designs. This is often the case with older switch installations that do not have a provision in the rail bracing to accept a rigid rail heater.
Our flexible rail heating elements provide up to 150 W/ft. of power at the switch point. The flexible design gives track personnel the ability to quickly install a switch heating system without having to remove rail bracing or needing to drill the rail for mounting hardware. The flexible rail heating element permits installation around rail bracing and other track obstructions, or behind rail braces that have a rail heater slot.
Coupled with Thermal-Flex high density, thermally insulated aluminum channel, lower wattage rail heaters can operate at maximum efficiency as heat is driven into the rail and not lost to the environment. The insulating properties and channel geometry can increase rail temperatures by as much as 50 percent versus non-insulated systems. This highly efficient insulated design can result in significant savings on power and installation expenses.
