HO Scale Hovey/Thermon HellFire 900 Regular Profile Switch Heater Set
Product Details
Hovey/Thermon Hellfire 900 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.
