Research has shown that exposure to the surfaces of certain metal alloys will kill cultured colonies of E.coli and L. monocytogenes within just a few hours at temperatures as low as 39°F (4°C). A heat exchanger with a proprietary fin design exhibits aggressive anti-microbial behavior, equivalent corrosion resistance to stainless steel, and similar heat transfer performance to standard coil construction. Designed for food processing applications where there is concern about possible food contamination with pathogens, the heat exchangers eliminate the need for coatings that can chip and flake off. Industrial process coils for food processing can have finned heights up to 120"; finned lengths up to 360"; and up to 24 rows deep in the direction of airflow.
