HELLFIRE Gas Fired Forced Air Railway Switch Heaters
Track & Switch Heater
Thermon Hellfire 900/905 and Hellfire 400 gas fired forced air switch heaters clear ice and snow from heel to point of switch. These snow clearing devices consist of a blower, combustion chamber, and ducting system that delivers heated air to the entire switch.
The blower is an electrically powered centrifugal fan. Air from the blower enters the combustion chamber and is used for combustion and make up air. The heated air exits the combustion chamber and is ducted below the rails to the point nozzles and track duct nozzles mounted within the switch. The air temperature is thermostatically limited for maximum snow clearing performance without burning ties or excessive softening of frozen ballast.
