Used Endothermic Generators-What Are They Worth?
The backbone of most heat treatment departments doing carburizing, neutral hardening or related processes is an endo generator to produce a carbon rich atmosphere. A typical older style unit can be seen in this photo-a Surface Combustion 5,000 CFH Endothermic generator and at one point in time this unit would have been in high demand but those days are long gone. The advent of air cooling, atmosphere control, multi retorts and automatic turn down of gas production on new units has rendered these older units pretty well obsolete and consequently almost worthless. New generators are actually selling fairly well these days, and even used units with most or all of these newer modifications have a ready market but it is pretty well the end of the line for the old timers such as this one.
