Vertical Storage Tanks

Assmann vertical storage tanks are more corrosion and chemical resistant than fiberglass, stainless, or mild steel.

Why a vertical storage tank?

Assmann vertical storage tanks (ICT, ACT, IFT) are rotationally molded from your choice of virgin high density crosslink or FDA-compliant linear polyethylene.

— Semi-translucent with gallon markers and access openings molded-in,
— One-piece seamless molded units, designed with wall thicknesses conforming to ASTM D-1998 standards for liquid storage,
— Excellent low temperature impact resistance,
— U.V. stabilized,
— Available in natural color, blue, green, yellow or black.

Common Use

Assmann poly storage tanks are ideal for space-saving use in plants and other confined areas, and possess excellent low-temperature impact resistance for vertical chemical storage.


Assmann values construction over cost-cutting. This means all of our tanks are slowly rotationally molded, cooled without water, and build without external shielding. This ensures a quality product that will last our clients years to come.

Curious about Assmann storage solutions? Listed below are the most common questions about our Vertical Storage Tanks. If you have additional questions about your next polyethylene storage tank, contact our experts.

What is the diameter of Assmann Vertical Storage Tanks?

The diameter for our vertical storage tanks varies between 20 and 143 inches.

What is the capacity?

Capacity varies with tank configuration. At a minimum, Assmann vertical tank capacity is 20g, and the maximum capacity limit is 12,500g.

What are the internal operating temperatures of Assmann tanks?

The softening point of our polyethylene material varies. For linear polyethylene, the softening point is around 120° Fahrenheit, and for Cross-Linked polyethylene, the softening point is approximately 140° Fahrenheit.

What is the tip-up height of my tank?

Tip-up height is the amount of space required to upright a storage tank from a lying position to standing vertically. This height varies from tank to tank. Assmann Corporation uses our AutoCAD software to calculate the minimum safe height required to up-right your tank.

What liquids can be stored?

Our storage tanks can be used for a variety of chemicals. Many of our tanks are used for Sodium Hypochlorite, Sulfuric Acid, Hydrochloric Acid, Sodium Hydroxide among other chemicals. Also, our tanks can also be used for less aggressive chemicals such as Polymers, Alum, Herbicides, Pesticides all the way to simple rainwater or drinking water. However, we do not recommend using our tanks for fuels or solvents.

Related Accessories

Preserve the life and efficiency of your tank with accessories customized to your specific tank.

Fill Line Assemblies

These assemblies make it possible to fill the tank from a convenient position outside the tank. The fill line consists of an exterior drop tube, 90-degree elbow, ball valve, male quick disconnect coupling, dust cap
and exterior pipe support bracket.

Tie Down Assemblies

Tie down assemblies are designed to handle both seismic and wind loads. These systems can be provided with or without stamped engineer calculations.

Flange Fittings

Flange fittings for polyethylene bulk containers provide a means to connect inlet or drainage plumbing through the wall of the tank.
