All Turbonetics intercoolers are manufactured using high-tech Vacuum Furnace Brazing (VFB). With VFB In this process all aluminum components that are to be joined by this process are clad with a thin layer of aluminum that has a melting point slightly lower than the base metal. All of the components, such as fins, bars, plates, headers, etc., are assembled and held together with straps or fixtures. This assembly is placed in a special high-tech the furnace where the atmosphere is completely evacuated. This is done to prevent defer oxidation of the heated aluminum by oxygen in the atmosphere. The temperature in the furnace is then brought up to the point to where the cladding melts and all surfaces in contact are bonded. The part is then cooled, resulting in a strong, bonded, leak- proof unit. All Turbonetics intercoolers employ bar and plate style construction. This style of intercooler is very rugged and accepts very high pressures and are at times used for oil coolers and industrial heat exchangers which that operate at 200 °degrees F (93.3 degrees C). Bar and plate intercoolers tend to be slightly heavier than tube designs. This style of construction does not require a separate header; the thickness of the core is the same thickness as the manifold or end tank. An extruded or welded conventional tube, intercooler has a header plate which is wider than the net thickness of the core. In that regard, for a given package size or space, the bar and plate intercooler will have more capacity and surface area.
