Third Rail Heating Elements

The SAN/OMNI third rail heaters use an advanced PFA polymer sheathing that will not ill form over its heating profiles. It will stay straight season over season. Note silicone heaters have their own set of problems as can be seen in the roofing heat trace market – a fungus can grow on the silicone.

This fungus by itself is not a problem but certain birds have an appetite for the fungus and can inadvertently destroy the heater. This is the reason the heat trace elements in the roofing market have eliminated silicone as a solution – no silicone – no birds!

The Heaters are encased in a Tracktherm outer fiberglass U channel and the inner section of the channel encases the heater in a Takcktherm insulation. This insulation presses the heater to the rail to optimize thermal connectivity and it’s insulative properties will increase the effective wattage from 40 watt/ft to over 50 w/ft.

The clips to hold the channel are made of a stainless steel and wrap around the rail for firm grip and placement. The clips place the heater to the highest point on the web as possible bringing it to the closest point of the rail.
