Corrosion-proof by material
Polymer (PP) air-to-air cores resist salt spray, acids and humid corrosive exhaust that destroy metal plates. They are the right choice for seafood processing, plating and coastal installations.
Performance notes
PP cores deliver sensible recovery with excellent chemical resistance and light weight, though temperature limits are lower than metal. Properly specified, they outlast metal in harsh duty by years.
Typical uses
Dried-seafood lines, wastewater treatment buildings, and any exhaust with corrosive or high-humidity content benefit most.
