	Alfa Laval spiral heat exchangers are the ultimate problem solver in extremely dirty and fouling process duties. The self-cleaning features inherent in the design, give unparalleled uptime between service intervals and quick and easy service turn-around.

ALSHE Cond

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

Applications

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)

ALSHE STW

The 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.

Applications

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

The 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.

Applications

Fouling liquids: containing solids, fibres, liquors, slurries and sludges
Liquid/liquid: preheating, heating, cooling, interchanging and heat recovery

Type 2

The 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.

Applications

Gases: pure vapour and mixtures with inert gases.
Vapour/liquid: Top condensers, reflux condensers, vacuum condensers, vent condensers, reboliers with fouling fluids and gas coolers.
