Coatings Services

Modine CIS produces two kinds of coating to protect the coils within heating, ventilation, air conditioning and refrigeration units.

E-Coat

ElectroFin® E-Coat is a factory-applied solution which involves full immersion.

ElectroFin® E-Coat was designed to protect HVAC&R coils from corrosive environments and is a market-leading product, used by every major OEM.

It has excellent corrosion resistance, as well as uniformity of coverage and coating thickness, and is recognised internationally as the best corrosion protection for fin and tube heat exchangers in coastal environments.

    Insitu

    Modine Insitu® is a spray-on coating, and can be applied either in the factory or in the field

    When time is critical, a field-applied spray coating may be the right solution. Modine Insitu® is a permanent, water-based, synthetic coating developed specifically for the protection of heat exchange units. It can be applied quickly at our facilities or on-site.

    While this technology does not match the complete immersion, factory-applied ElectroFin® E-Coat process, a spray-applied coating does provide a level of protection that is better than no coating at all. Applied by certified technicians, the coating is fast drying, with only a single application required.

    Modine Insitu® benefits

    • Luvata Insitu® process

    ES² technology

    Modine Insitu® contains ES² (embedded stainless steel pigment) technology, an anticorrosion coating specifically designed for the protection of coils mounted in corrosive areas. Coils will have a permanent, water-based synthetic coating with ES2 pigment applied to all coating surface areas without material bridging between fins.
