Highgate Air’s ProCorro XR is a specifically developed, tried and tested corrosion protection system. A polyurethane coating, impregnated with metallic pigment to prevent loss of heat conductivity, is applied to A/C condensers and evaporators in order to increase the lifespan of the parts in highly corrosive environments. The lifespan of parts treated with ProCorro XR has been found to be more than double* compared to parts without treatment.
