Poly Tanks or Chemical tanks as they are also known, are a 6,000 Gallon Polyethylene Roll-Off Tank and are used for storage of on site acid, chemical, or caustic liquids. These tanks use XLPE and are built on the same frame as a mini frac tank which allows them to fit into tighter spaces than a normal frac tank. These are perfect for being placed inside or just outside a facility to store caustic cleaning chemicals or process liquids that can’t be stored by traditional means. These tanks are equipped with ports and valves and can be paired with acid compatible hoses to allow easy transfer of stored liquid also. We also rent air powered acid transfer pumps for liquid transfer.
