OVERVIEW
Walker Stainless Equipment Co. 20,000 Gallon Jacketed Vertical Stainless Steel Storage Tanks — Serial Numbers VSHT-6445R through VSHT-6448R, Job Numbers 12103–12106, Date February 1997. Four matching SA240/T316L stainless steel vertical storage tanks with ammonia (R-717) refrigerant jackets, manufactured by Walker Stainless Equipment Company, Inc. (a Carlisle Company) in Elroy, Wisconsin, USA. Each tank features 20,000 gallon capacity, 96 sq ft jacket area, 150 PSIG design pressure, 255 PSIG test pressure, and jacket MAWP of 150 PSIG at 300°F with minimum design metal temperature of -20°F at 150 PSI. Approximately 27 feet tall by 12 feet radius. Total combined capacity of 80,000 gallons.
Each tank is equipped with a 10 HP agitator motor (washdown or inverter duty, 3-phase, Frame 215TC, TEFC enclosure) for product mixing. All four tanks are matching units manufactured in the same job batch with consecutive serial numbers, confirming they were designed and built as a complete matched set. Heavy-duty SA240/T316L stainless steel construction ideal for dairy processing, food and beverage production, pharmaceutical manufacturing, chemical storage, or any application requiring large-capacity jacketed stainless steel storage with R-717 ammonia refrigerant cooling capability.
Note: These tanks contain or have contained ammonia (R-717) refrigerant in the jacket system. Buyer is responsible for proper ammonia handling, evacuation, and compliance with all applicable federal, state, and local regulations regarding ammonia refrigerant systems.
