AOD-IWIOISTUW6 - CLEAN, QRV —» REFRIGERANT
Own a refrigeration or air-conditioning system? Maybe you didn't know it but the refrigerant must be kept dry and free of acid. Even a tiny drop of moisture can cause expensive breakdowns, and corrosive acids cause sludge, with the same result. An exceptionally efficient drying agent, like ALCOA® Activated Alumina, is required for such an exacting job. That's why Ansul Chemical Company, Marinette, Wisconsin, uses ALCOA Activated Alumina H-151 in their T-Flo® Drier, illustrated. Specially treated by Ansul and called Andrite,® this amazingly efficient desiccant in pellet form does double duty . . . keeps moisture way below the critical level . . . picks up far more acid than could ever accumulate. Result: fewer breakdowns, money saved. Shouldn't you investigate today?
