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. The Association has developed a set
of standards for the manufacture, installation and safe operation of BAHXs.
