3,000 hours. Level 10. ≤ 0.01% surface corrosion.

That's the result recently achieved by our Bluefin coated coils in a salt spray test conducted in accordance with ASTM D1654-2008.

This is the highest possible rating for corrosion resistance.

Bluefin coated coils are also a standard supplier across all of our heat exchangers.

For Consultants, Contractors and Building Owners, this means greater confidence in the long-term durability and performance of equipment, particularly in coastal, humid and other corrosive environments where coil protection is critical.
