Diesel Exhaust Fluid (DEF) begins to crystallize and freeze at 12°F. DEF stored in an underground tank is warmed naturally by geothermal heat, but the DEF product lines nearer the surface are subject to lower temperatures. Heat trace cabling and heat trace piping solve the freezing problem but are expensive to install.
The Fatboy Electric Geothermal DEF Heating System harvests the free geothermal heat trapped underground and puts it to work! It monitors the DEF product temperature and, when needed, activates a pumping system that circulates warm product from the underground tank throughout the DEF system to prevent freezing.
Using geothermal heat allows you to install much less expensive single wall piping that has no heat trace cable. Lower installation costs combined with lower maintenance make the Fatboy Electric Geothermal System a must-have for your next DEF installation!
