ALFA LAVAL, ALSHE Cond HEAT EXCHANGERThe standard spiral heat exchanger design brings the advantages of ultra-efficient self cleaning effect, that maximizes uptime operation. A perfect fit for fouling duties!


The Alfa Laval ALSHE Cond spiral heat exchanger can be used as:

  • Condenser
  • Reflux condenser
  • Reboiler
  • Gas cooler
  • Heater
    (even in presence of very large vapour or gas flows and/or very low pressure drop.



ALFA LAVAL, ALSHE STW HEAT EXCHANGERThe all-round heat transfer solution. Exceptional compactness and self-cleaning design make Alfa Laval spiral heat exchangers extremely versatile. Ideal for everything from dirty fluids to high vacuum condensation.

Standard and custom ALSHE STW ranges

The Alfa Laval ALSHE STW is suitable for any sludge/water duty, either as a pre-designed standard, or as a custom design.


The spiral heat exchanger offers unique abilities within sludge treatment applications such as:

  • Heating of sewage sludge in digesters
  • Heating stages in pasteurization systems
  • Preheating of sludge for enhanced dewatering
  • Cooling of industrial sludge and waste waters
  • Heat recovery


Type 1

ALFA LAVAL, Type 1 HEAT EXCHANGERThe all-round heat transfer solution for liquid-liquid fouling duties. Exceptional compactness and self-cleaning design make the spiral heat exchangers extremely versatile even when operating at high pressures and high capacities. Excellent choice when one, or both, fluids are fouling, due to its self-cleaning effect.

Type 2

ALFA LAVAL, Type 2 HEAT EXCHANGERThe Alfa Laval Type 2 spiral heat exchanger is used for 2-phase duties, both condensing and evaporation (re-boiling). In this configuration the spiral is always in a vertical position. Cross-flow condensing with lowest possible pressure drop.

Type 3

Alfa Laval Spiral Range Type 3 ImageThe Type 3 SHE is often called a “steam heater” and has a mixture of Type 1 and Type 2 features. The main feature is that the liquid being heated by the steam is generally fouling, therefore the circuit is designed to be accessible for cleaning, which is not the case with the normal Type 2. In addition the counter-current nature of Type 3 allows tighter temperature approaches that are achievable with the cross-flow nature of Type 2.
