Following the success of the TD500 GSE Cabin Heater, Therm Dynamics has introduced the TD500 IDF. This portable standalone heater is designed to preheat engines and thaw frozen hydraulics or doors. As an added bonus, Therm Dynamics designed the IDF to function as a portable maintenance station with high spot heat and a 6.0KW generator to run tools and lights. The TD500 IDF heater is designed to meet all of a ground handler's operational needs in the most extreme and demanding conditions.
