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.
Even more with Contherm® Max double wall heat exchanger
The Contherm® Max double-wall scraped surface heat exchanger boosts capacity for demanding applications while maintaining gentle, hygienic product treatment. This solution expands the Contherm® family to meet even more operational needs.
