Coatings Services

Modine CIS produces two kinds of coating to protect the coils within heating, ventilation, air conditioning and refrigeration units. ElectroFin® E-Coat is the premiere brand in the HVAC&R industry and offers the highest level of corrosion protection available from an electro coating provider.

Insitu® Spray Applied Coating provides your HVAC&R equipment with the ultimate in corrosion protection. Mechanical Engineers that are specifying a protective coating system for their equipment always have the opportunity to specify both ElectroFin® E-Coat and Insitu® Spray Applied Coating. Using both of these products in tandem puts your equipment on the ultimate protection path and guarantees you the very best in corrosion protection.

E-Coat

ElectroFin® E-Coat is a factory-applied solution which involves full immersion. ElectroFin® E-Coat is a proprietary technology that can only be applied at our facilities. Our unique process provides an electro-deposition coating process that involves epoxy paint particles evenly suspended in deionized water. When electrically charged, the paint particles migrate to and bond with aluminum, copper, and other conductive metal surfaces that form the heat exchanger coils. Resin and pigment migrate to the part, and an organic uniform film is irreversibly deposited.

ElectroFin® E-Coat is an internationally recognized e-coating process that has been reapplied by our engineers and redesigned to provide the ultimate protection for condenser and evaporator coils.

ElectroFin® E-Coat is ideally suited for coastal and offshore environments as well as industrial areas with high humidity and aggressive atmospheres, such as electrical power plants, refineries, waste water treatment plants, and urban areas with nearly permanent
condensation and high pollution. ElectroFin® E-Coat extends the lives of HVAC&R heat transfer coils and components, reduces maintenance and operating costs, and is used by every major OEM.

    Insitu®

    ADD INSITU® SPRAY APPLIED COATING TO YOUR HVAC SYSTEM

    To provide your HVAC&R equipment with the ultimate in corrosion protection, specify Insitu® Spray Applied Coating to complete the job. Mechanical Engineers that are specifying a protective coating system for their equipment always have the opportunity to specify both ElectroFin® E-Coat and Insitu® Spray Applied Coating. Using both of these products in tandem puts your equipment on the ultimate protection path and guarantees you the very best in corrosion protection.

    Insitu® Spray Applied
    Coating 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. Insitu® Spray Applied Coating 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.

    Insitu® Spray Applied Coating benefits

    In environments where corrosion is highly present (marine, industrial, agricultural, or areas where there are harsh chemicals), the system heat transfer coils can corrode very quickly, resulting in efficiency and capacity loss. This can be expensive in terms of energy consumption, repair bills, and system downtime.

    Corrosion leads to many problems, not just from an appearance factor, but performance as well. Loss in efficiency will generate higher energy use and bills to follow. In seaside locations especially, the operating performance of unprotected condenser coils may decrease over 50% in a single year. As a building and system owner, the cost of energy continues to rise, and it makes no sense to pay for a high-efficiency system that cannot effectively operate as intended.

    • The Insitu® Spray Applied Coating process

    ES² technology

    Insitu® Spray Applied 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.
