.Goliath Series Secondary Drain Pans are the strongest, most rugged HVAC secondary drain pans on the market today. Made With Pride in the USA from a patented blend of advanced polymer DexElar material, Goliath Series Secondary Drain Pans are engineered with superior one-piece structural strength to produce a nearly indestructible drain pan with rolled edges and no seams. Goliath Series Secondary Drain Pans provide extreme temperature durability -20° F (-28°C) to 260° F (126.7°C), high tensile strength, crack/split/leak/rust resistance, and are self extinguishing. DexElar material is UL 94-5VA flame retardant and ASTM E-84 Class C rated for flame spread and smoke developed for interior wall and ceiling finishes - a superior level of safety and protection compared to traditional HVAC/R secondary drain pan materials. Each pan is strong enough to hang using only one pair of steel support struts, ensuring a quick-and-easy professional installation. They also feature a network of built-in risers, which are compatible with a wide variety of sizes of HVAC units and eliminate the need to shop around for additional risers or mounting blocks.
