Take a closer look inside a heat transfer coil coated with ElectroFin® E-Coat.

A typical tube and fin, or micro-channel heat transfer coil has literally thousands of aluminum fins and copper tubings. The density and size of the coils varies, but for the most part, all are very thick. It’s important to remember that when fin spacing on condenser coils becomes denser, a thicker coating can cause fin bridging to occur, which severely restricts the efficiency of a condensing unit.

ElectroFin® E-Coat is micro thin (between 0.6 and 1.2 mil thick). Thin coatings are better for heat transfer. Flexibility and impact resistance are also key. An inflexible or impact-resistant coating will crack or flake when the coils get hit or bent, which is a normal occurrence. When even the smallest portion of uncoated metal is exposed, the underlying metal will begin to corrode.

E-coating aluminum micro channels can be even more difficult, but not with ElectroFin® E-Coat. ElectroFin® E-Coat has high edge build technology and can be found on over 100,000 micro channel condensers around the world – providing corrosion protection in some of the harshest environments known to man.
