Cone Bottom Tanks

Cone bottom tanks are poly storage tanks with an angled base that directs material to a center bottom outlet, designed for applications where complete or near complete drain down is required. They are typically specified for batching, mixing chemicals, large dry flowable, product transfer, and process applications where minimizing residual material in the tank is part of the design requirement. Available sourcing includes cone bottom tanks from Chemtainer, CRMI, Enduraplas, and more.

Cone bottom poly tanks are the right call when drain down efficiency is a design requirement. The angled cone base concentrates material at a center bottom outlet, making them the standard choice for batching, dosing, and chemical transfer where residual material in a flat bottom tank is not acceptable. Select polyethylene models use resin that complies with U.S. Food and Drug Administration regulation 21 CFR 177.1520 (c) 3.1 and 3.2; confirm material suitability for your specific liquid and concentration before specifying.

A support stand is required in nearly all cone bottom storage tank installations to provide outlet clearance for valve and piping connections. Stand type, outlet size, and connection configuration vary by model. Mixer stands and mounting provisions are often paired with cone bottom tank layouts where blending or solids suspension is required. Cone bottom tank capacities can extend from small process sizes up to 10,000 gallons in standard molded lines, with larger custom cone bottom and slope bottom tanks available up to 50,000 gallons. Cone angles commonly include 15°, 22.5°, 30°, 45°, and 60°. Spec sheets, dimensional drawings, and submittal documentation are available through a sales specialist.
