Sanitary Pressurized Liquid Dispensing Tanks

Store and dispense liquids in food, pharmaceutical, and beverage plants—these tanks attach to a compressed air source for use in sanitary environments. A dip tube draws liquid from the bottom of these tanks for dispensing and spraying. They’re made of 316L stainless steel for excellent corrosion resistance, and have an electropolished finish that prevents product buildup and bacterial growth. Connect them to valves, hose, and caps with quick-clamp sanitary tube fittings, which are easier to sanitize than threaded fittings. Tanks comply with ASME BPVC.VIII safety standards for pressure vessels.

Safety regulations restrict sales to the listed jurisdictions/areas.

These tanks have drain ports on the bottom to remove condensation. All other ports can be used as inlets or outlets in any configuration.

Stainless steel tanks are more corrosion resistant than steel tanks.

Safety regulations restrict sales to the listed jurisdictions/areas.
