API Heat Transfer's line of Airtech Air-Cooled Heat Exchangers are an all-aluminum bar & plate design featuring a wide variety of thermally efficient internal and external fin patterns. Fins are laid between aluminum braze sheets and fitted with header and face bars. The assembled unit is placed into one of the three modern vacuum braze furnaces where precise control of time and temperature produces a unified core. Manifolds designed to meet each customer's particular piping requirements are welded into place to complete the cooler. API can supply cores only when manifolds already exist or must be fitted in the field.
