The fundamental difference between a brazed heat exchanger and a collapsible one is that in a brazed one, a package of stainless steel plates is sealed not with gaskets, but by soldering the plates using copper solder. This design feature determines the main advantages and disadvantages of a brazed heat exchanger.
    Advantages of brazed heat exchangers:
  • absence of a massive housing of the clamping structure;
  • low cost;
  • resistance to long-term high-temperature loads;
  • Ability to work with freons and other volatile agents;
  • Good fatigue strength;
  • The design of the plates is designed for a long service life;
  • Short delivery time;
