Brazed Plate Heat Exchanger

Brazing the stainless steel plates together eliminates the need
for gaskets and thick frame plates. The brazing material seals
and holds the plates together at the contact points ensuring
optimal heat transfer effciency and pressure resistance. The
plate design guarantees the longest possible life.
