Frost Plug Heater
Heats engine coolant and block to aid cold weather starting.
 

Cold, freezing weather is never kind to any type of engine or other mechanical equipment. And that includes the engine and related components of your Thermo King truck or trailer refrigeration unit.

By installing a Thermo King Frost Plug Heater, you can easily heat the engine block and related components when the unit is sitting overnight or an extended period. Once installed, the Frost Plug Heater plugs into any 110 volt outlet.

Not only does this simple heating device aid cold weather starting, it also increases the life of battery, starter, glow plugs, and the overall value of the refrigeration unit.

Frost Plug Heaters are available for all Thermo King two, three, and four cylinder engines. Each can be easily installed at the same time you're winterizing the unit.

Compatible with "Smart Reefer" units (SB-III SR, Super-II SR and SR Multi-Temp)
