Every Bravo Milano condenser cabinet is treated with a multi-stage anti-corrosive powder coating to withstand the harshest outdoor elements. This is especially important for Tri-Zone systems that are exposed to rain, snow, and salt air year-round. Our Bravo Milano 12,000 BTU Universal Floor/Ceiling condensers look brand new even after years of service thanks to this treatment. To further protect the base of the unit from rust, mounting it on a Ground Stand is a smart preventative measure. We also offer Line Set Covers that are UV-stabilized to match the longevity of the condenser cabinet. For those in coastal areas, this coating is the difference between a system that lasts 15 years and one that rusts out in five. It is a commitment to quality that extends from the internal electronics to the outer shell.
