Epoxy Coated Fins

Details

APPLICATION
• Coils and air coolers for the food industry
• Heating and cooling coils in aggressive environments
• Coils for marine duty
• Dry coolers and air-cooled condensers
• Heat pipes for heat recovery


BENEFITS
• Over 300% more resistant to corrosion than bare aluminum fins
• High thermal conductivity with negligible impact on heat transfer
• Flexible - will not peel, crack or chip
• Highly resistant to abrasion
• Fin collar heights of up to 1/2" (2 fpi)
• Coating does not support growth of micro-organisms

SPECIFICATIONS
• The coating system (EPPU) consists of the base aluminum alloy prepared with a chemical conversion layer coated with a colorless epoxy layer and a final polyurethane top coating.
