THERMON THS2031-0821 Round Tubular Rail Heaters

The Fastrax™ electric round tubular rail heater is ideal for older switch installations that do not have the relief available for flat profile heaters. It resides within the recess web area of a rail to keep railway switch components free of ice and snow. The heavy duty stainless steel construction resists corrosion and offers protection and durability in rugged environments. The heater is designed to withstand heavy shock and vibration found in rail traffic, and is suitable for use in extreme weather conditions. The wire inside of the heating element is made of high grade resistance alloy and provides the source of heat. The resistance wire is surround by highly compacted magnesium oxide insulation, which provides excellent electrical and thermal properties.Thermon has internal capabilities dedicated to the production of the highest quality tubular heating elements. We use only the best commercially available materials and we use design parameters proven to maximize element life expectancy.
Features
- Electrically isolated sheath
- Fastrax™ patented spring clamp technology allows for expansion and contraction of the heater without binding or losing contact with the rail
