Alfa Laval Inc. Welded Spiral Heat Exchangers 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. In this configuration the spiral heat exchanger is always in a vertical position. The compactness of the Alfa Laval SHE Type 2 and the fact that it is mounted vertically allows it to be installed with a very small footprint compared to the equivalent shell-and-tube unit and reduces supporting structures and piping complexity. The Alfa Laval SHE Type 2 has a cross-flow rather than counter-current flow. Because of the good channel gap on the condensing side there is generally a very low pressure drop on the condensing circuit, therefore it is ideally suited to vacuum condensation duties. 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.
