Stainless Steel
Insulated Tank

The insulated tank was designed for processing that requires precise temperature regulation.

This tank is much like other sealed vessels, with one major difference – the stainless steel tank is wrapped with a thick layer of polyurethane foam.

Polyurethane foam is one of the best choices of insulation material, especially when dealing with fluids. It offers great thermal insulation, is resistant to moisture and water and has a low density, making it lighter.

A large, dimpled jacket makes sure the temperature inside the insulated tank is always optimal. Thanks to the vertical construction of the cooling jacket, the stored liquids will be efficiently chilled even if the tank is not full to the brim.

Combined with the PU foam layer, the insulated tank jacket makes your temperature control system even more efficient and cost-effective.

Durable, high-quality materials enable the tank to stay in pristine condition, even after years of professional usage.

AISI 304

The insulated vessel is made out of AISI 304 quality stainless steel. An upgrade to AISI 316L grade stainless steel is available for high-corrosion environments.

Marbled Finish

A high-polish, marbled finish is applied to the outside of the tank. Matte and Scotch Brite finishes are also available upon request. The inside is BA (IIId) polished.

Conical Eccentric Bottom

The sealed tank comes with a conical eccentric press-molded bottom by default. Adjustments are made with the tank diameter, so the discharge is always easy.

Conical Eccentric Top

An eccentric conical top made by press-molding is standard for the insulated tanks. Adjustments are made in accordance with the vessel size and diameter.

Insulation Layer

The tank is wrapped with a thick layer of polyurethane foam which provides great thermal insulation. The PU foam is resistant to moisture and water, making it perfect for stainless steel tanks.

Dimple Jacket

A dimple jacket is a thin, spotted shell that regulates tank temperatures with the help of a cooling/heating medium such as glycol. They are made of light-weight materials and spot-welded for minimal additional weight.

Stacking Technology

Make smart use of your limited cellar space by stacking tanks on top of each other. Stacking allows you to reorganize your production line and make it more efficient than ever.
