Scraped surface heat exchangers

The Contherm® scraped-surface heat exchanger allows for rapid cooling and gentle heating of highly viscous fluids. The heat exchanger contains motorized surface-scraping blades that prevent fouling and protect delicate food and personal care products.

Scraped surface heat exchanger

When to select a scraped surface heat exchanger?

  • When the duty is cooling a viscous fluid after pasteurization for packaging.
  • When the duty requires the crystallization of fluids at the surface of the heat exchanger..
  • When the product viscosity or particulates would cause excessive fouling and maintenance costs.
  • When gentle and precise heating is desired to preserve key texture, flavour or nutritive components in a food product.

Contherm® scraped surface heat exchangers are used for cooling viscous, heat sensitive, crystallizing or sticky food products. The heat exchangers are also used for heating fluids with sensitive particulate matter in manufacturing pharmaceuticals and personal care products.
Alfa Laval’s Contherm range is the market’s most complete scraped-surface portfolio. Alfa Laval’s rotating scraping technology continuously removes fouling material during processing. Gentle handling preserves the quality of shear-sensitive products while simultaneously providing high efficiency with a larger flow area and reduced pressure drop.
