About. ALPEMA ®, the Brazed Aluminium Plate-Fin Heat Exchanger Manufacturers' Association represents the world's five major manufacturers of brazed aluminium plate-fin heat exchangers (BAHXs). These are very compact exchangers built to a high specification for use in air separation plants and a wide range of other petrochemical and refrigeration applications.
Brazed Aluminum Heat Exchangers Charts Brazed Aluminum Heat Exchangers (also known as Plate Fin Heat Exchangers) and Cold Boxes are at the heart of low temperature natural gas, air separation and petrochemical processes worldwide. Building the World's Largest
Brazed Aluminum Plate-Fin Heat Exchangers Reduce Costs Mar 01, 2000 · Brazed aluminum plate-fin heat exchangers commonly are installed directly inside distillation columns to eliminate costly piping. Compact size and versatility are typical features of a brazed aluminum plate-fin heat exchanger. The unit's compact size is due to the heat transfer fins and the aluminum material.
Apr 06, 2016 · Brazed-aluminum-plate-fin heat exchangers (or core exchangers or cold boxes) as they are sometimes called, were first manufactured for the aircraft industry during World War II. In 1950, the first tonnage air-separation plant with these compact, lightweight, reversing heat exchangers began producing oxygen for a steel mill.
Brazed Aluminum Heat Exchangers - Chart Industriesto ensure a bond between each fin and corresponding plate. Even in a small heat exchanger that means millions of brazed joints. Each one is formed through capillary action as the brazing alloy on the surface of each plate melts during the high temperature operation and fuses to the parts in contact with it. Following brazing, BAHX construction
