Contherm® scraped surface heat exchangers are a robust solution for a range of industries and applications: from food, chemicals and pharmaceuticals to health and beauty. Based on Alfa Laval’s decades of expertise in thermal exchange, each unit is specially engineered to handle viscous, heat sensitive, crystallizing or sticky products, as well as those with sensitive particulate matter. 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.
What is a scraped surface heat exchanger?
What is a scraped surface heat exchanger, and how does it differ from static designs? Unlike traditional models that risk fouling and thermal inefficiency with viscous or crystallizing materials, scraped surface heat exchangers use rotating blades to remove buildup from heat transfer surfaces continuously.
This ensures consistent heat exchange, improved hygiene, and higher process uptime, especially in the food industry where maintaining product integrity is key.
Why choose Contherm®?
With over 50 years of expertise, Alfa Laval is the only supplier to offer the full spectrum of scraped surface heat exchanger technologies. Contherm® systems are designed to meet evolving process needs, offering unmatched durability, hygiene, and performance.
Single wall or double wall scraped surface heat exchanger: Which Contherm® should I choose?
Choosing between a single-wall or double-wall system depends on your process conditions, product type, and capacity requirements. Alfa Laval helps customers identify the best scraped surface heat exchanger design by evaluating product behavior, temperature demands, and process goals.
