Welded spiral heat exchangers

Alfa Laval spiral heat exchangers are designed to handle the toughest heat transfer challenges. Whether it’s frequent fouling from dirty media, or limitations from pressure drop and floor space, they are the ultimate problem solver for liquid-to-liquid and two-phase duties. The robust, efficient and compact designs keep both installation and maintenance costs extremely low, and they have a proven reputation for almost never fouling up.

Improving sustainability with Alfa Laval’s spiral heat exchangers

  • Minimal fouling, or clogging, in duties involving very dirty, highly viscous or particulate media, ensures uptime
  • Easy-to-open design makes cleaning quick and simple, ensuring low maintenance costs
  • Reduced pipework and steel structures means lower installation costs
  • Increased energy savings and reduced emissions thanks to thermal efficiencies 2-3 times higher than comparable shell-and tube exchangers
  • Each unit is fully customized, offering the best thermal fit for the specific duty
