Low fouling condenser applications apply to specific beverage dispensing or similar machinery and appliances where the finned surface of the coils may become coated with substances that would greatly increase the capture of airborne trash and contaminants (grass, chaff, etc.)  By designing the fins and tube arrangement of the coils to still achieve acceptable performance after contamination in these environments the service life of the appliance is greatly extended.
