Vertical Tank with Secondary Containment provides dual wall protection in one product and is designed for commercial and industrial applications. The double wall tank design allows safe secondary confinement of hazardous chemicals and liquids, such as calcium chloride, sodium hydroxide, fertilizers, urea, used motor oil, liquid polymers, surfactants and lubricants that could cause major environmental damage if accidentally discharged or spilled. This combination of tanks is selected for primary storage of liquids with secondary containment in indoor applications. Tanks are manufactured from UV infused polyethylene that stand up to harsh conditions and is designed for the containment of all chemicals rated for contact with polyethylene to a maximum of 2.0 specific gravity for Primary Vertical Tank and 1.5 specific gravity for Secondary Containment Tank.
