Double-wall scraped surface heat exchanger
Achieve high-capacity processing with gentle handling for shear-sensitive products, efficiently managing particulate-laden and crystallizing materials while optimizing energy use and minimizing maintenance demands.
Great for making:
The Contherm® Max from Alfa Laval is a double-wall scraped surface heat exchanger designed for high-capacity production, specifically tailored for challenging heat-sensitive and particulate-rich products. Its vertical design features a large heat exchange surface area, tripling the capacity compared to conventional single-wall systems. At its core, an engineered rotating scraping assembly continuously removes fouling materials, optimizing heat transfer from the bottom entry to the top exit. Ideal for industries like food processing, cosmetics, and pharmaceuticals, it efficiently processes products including sauces, spreads, whipped products, and personal care goods. A single drive motor reduces energy use by over 30%, while its plug-and-play assembly ensures easy integration into production lines. Available in corrosion-resistant materials, the Contherm® Max supports optional customization and adheres to industry compliance standards. Its Cleaning-in-Place system streamlines maintenance, minimizing downtime and ensuring consistency in long-term operation.
