Conical Bottom Tanks

Conical bottom tanks (OTCB & ICB) are available in seamless molded one piece units from either virgin high density crosslink or FDA-compliant linear polyethylene.

Why a Conical Bottom Tank?

A funnel shaped conical bottom with 30° or 45° slope is molded-in as are gallon markers and access openings. They have more resistance to corrosion and chemicals than fiberglass, stainless or mild steel. Wall thickness conforms to ASTM D-1998 standards for liquid containment.

— Excellent low temperature resistance
— UV stabilized against degradation
— Available in natural color or optional blue, green, yellow or black

Common Use

Conical bottom tanks are often used in process applications, because of their ability to drain completely and efficiently.
