Enfab, Inc. was founded in 1980 by Joe Killebrew to build the FRE-FLO heat exchangers he had invented 40 years earlier. In addition to the FRE-FLO heater, Enfab also custom designs and fabricates a wide variety of other shell and tube heat exchangers including "U" tube exchangers, condensers, evaporators, tank heaters, suction heaters, aftercoolers, intercoolers, oil coolers and double-wall exchangers. We can also design and build a complete system for you, complete with controls, sensors, and pumps.
