Modine corrosion protection paint system

Reliable performance through corrosion resistance.

The site conditions, the outside environment, the fluid conditions inside the heat exchanger, the general operating conditions, and operational lifetime requirements will help to determine the required corrosion protection. Corrosion main Modine’s paint system has been laboratory tested to ensure that our coolers have the longest possible service life and enjoy a reputation for reliability.

ElectroFin® E-Coat

Modine’s ElectroFin® E-coat with UV topcoat guarantees corrosion protection and long-term reliability.
Coolers treated with ElectroFin® E-coat are corrosion resistant for many years, even in the harshest environments.


ElectroFin® E-coat is ideally suited for industrial areas with high humidity and hostile atmospheres, such as power plants, refineries, steam turbines, deserts, coastal and offshore areas with high salinity, and buildings or areas with nearly permanent condensation and high pollution.

Thickness of Coating

Thin coatings are better for heat transfer, while thick coatings can lead to diminished heat transfer and restricted airflow over the condenser coil.

It’s important to remember that when fin spacing on condenser coils gets denser, a thick coating can cause fin bridging to occur, which severely restricts the efficiency of a condensing unit.
