Sondex brazed plate heat exchanger consists of a number of thin acid-resistant precision stamped stainless steel plates with copper brazed gaskets.

The plate packs are brazed  with two end plates and connections. Vacuum brazing at extremely high temperatures provides a permanently sealed heat exchanger. The final result is a strong and compact plate heat exchanger with extremely high heat  transfer capability.
