COLVILLE, Wash. - Colmac Coil Manufacturing, Inc. has developed a new breakthrough technology for air cooling and heating coils used in food processing equipment where there is concern about possible food contamination with pathogens.
"The cost to a food manufacturing company of a single product recall because of contamination more than justifies specifying this new anti-microbial coil construction. Think of this new development from Colmac Coil as ‘cheap insurance'," said Bruce Nelson, President of Colmac Coil.
Recent 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 degrees Fahrenheit.
Based on this research, Colmac Coil's patent pending fin construction design exhibits aggressive anti-microbial behavior, equivalent corrosion resistance to stainless steel, and similar heat transfer performance to standard coil construction.
Benefits of this new coil construction include:
- Killing of bacteria where UV lighting can't reach
- Corrosion resistance to harsh cleaning chemicals
- Anti-microbial protection of the entire heat transfer surface
- Eliminates the need for coatings which can chip and flake off
"Conventional fin and tube coils with many rows deep are inherently difficult to clean and sanitize," Nelson said, "the active anti-microbial behavior of this new fin material kills bacteria even deep in the interior spaces where UV lighting and other disinfection methods just cannot reach."
When combined with stainless steel tubes, the new coil construction resists corrosion when exposed to normal concentrations of cleaning chemicals commonly used in the food processing industry such as potassium hydroxide (caustic soda) and sodium hypochlorite (chlorine bleach).
Colmac Coil can incorporate this new anti-microbial coil construction into a wide variety of its cooling equipment, including: process room evaporators, critical process air handler coils, proofing coolers, cooking oven coils, IQF and spiral freezer coils.
These coils are compatible with all commonly used refrigerants such as ammonia, CO2, halocarbons, glycols and brines.
