Spiral heat exchanger
60 bar, -100 - 450 °C
Tranter
Spiral heat exchangers are ideally suited for handling “difficult” fluids, such as sludges, slurries, heavyfouling, viscous and/or particle-laden liquids, but also where fluids have to condense or evaporate at low pressure drops. Each spiral heat exchanger is a custom-made product and can be made from any cold-workable and weldable material.

The concept of a spiral heat exchanger is as simple as it is sophisticated. Two or four long metal strips, onto which spacer studs are welded, are wound around a core, thus creating two or four equally spaced single-passage channels. The concentric shape of the flow-passages and the studs create turbulence already at low Reynolds numbers. By optimizing the flow pattern heat transfer is enhanced, whilst fouling is reduced. This results in a compact and space-saving construction that can be readily integrated in any plant and reduces installation costs.
