Tanks - Cylindrical - Open-Top - Conical Bottom (COC)

STI's complete inventory of top-quality rotomolded cylindrical tanks assures our ability to provide what you need, when you need it. A tank molded in virgin linear polyethylene is the ideal choice for storage, mixing and/or feeding a vast array of liquids. These tanks provide corrosion protection and also prevent metallic contamination. A low-cost alternative to metal, our sanitary tanks also offer complete drainage and a wide assortment of compatible accessories.

Cone bottom tanks offer many advantages for your ultra clean applications. Flushing, cleaning, and complete drainage are key requirements for most medical, research, or pharmaceutical installations. Cone bottom tanks can be used in a wide variety of applications including dialysis bicarb systems, decantation of similar liquids, buffer mixing, reverse osmosis, blending, media preparations, small scale production and more. High viscosity solutions are also easier to handle in a cone bottom tank. Modifications can be made to accommodate special size needs.

The units are made to each customers unique process requirements. Sampling devices, spray jets, mixers, three drainage options, and specified fitting placement are just a few examples of the options available.

Whether you need a viewing window for a decantation process, a mixing nozzle for your bicarb mixing system, or a dozen sanitary fittings for your DI water loop, STI's COC series tanks are a great starting point.
