ACO Container Systems, a division of Rotoplast Inc., is known as one of the leading manufacturers of high-quality, rotationally molded tanks and other rugged polyethylene products in North America. We have more than 40 years of experience in this business and are ISO 9001:2015 certified.
Rotational molding is a molding technique used to produce hollow parts. It is a cost-effective method to produce large, hollow plastic parts because it does not involve the use of pressure in the process. It uses a hollow mold tool where the resins are heated and rotated simultaneously. After the resins are well-distributed and fused on the surface of the mold, the mass is then cooled and the hollow mold is removed. The resulting product is a seamless part with uniform thickness. Products made with rotational molding are known for their strength and durability.
ACO manufactures a complete line of plastic tanks including closed top storage tanks, open-top storage tanks, double-wall storage tanks, pallet tanks, sloped bottom tanks, conical bottom tanks, tote barrels, flat bottom tanks, material handling containers, and horizontal tanks for use in a wide range of applications.
To identify the chemicals that can be safely stored in tanks, check the compatibility of the chemical with polyethylene in the Material Safety Data Sheet (MSDS) provided by the chemical supplier. In addition, our tanks can store and transport liquids with specific gravities of less than 2.2.
All our tanks are manufactured out of high-grade high-density polyethylene (HDPE) or cross-linked polyethylene (XLPE), making our tanks very tough, durable, chemical resistant and dimensionally stable. Our tanks perform better than mild steel, stainless steel, and fiber-reinforced plastics (FRP) for most chemical applications.
Our tanks have high resistance to corrosion and chemical attack, allowing them to safely store chlorine, sulfuric acid, sodium hydroxide, hydrochloric acid, and many more. Our tanks are also suitable for holding potable water as our HDPE resin is FDA, RoHS and NSF 61 compliant.
The largest tank we produce has a capacity of 16,500 gallons.
Polyethylene is a high-quality thermoplastic with excellent physical and chemical resistance. With proper handling, tanks made of polyethylene are less likely to be damaged. Our tanks are also designed to resist low temperatures, so they maintain good integrity even when placed in cold areas.
No. Generally, plastic tanks are designed for use at atmospheric pressures.
Exposure of plastic tanks to sunlight for extended periods can causes discoloration, stiffening, and eventual cracking. But all our tanks are infuse with UV stabilizers with a UV ratings up to UV-20 that can significantly reduce the harmful effects of UV light, thus extending the service life of the plastic tanks.
The life expectancy of a tank depends on the type of material stored, storage location, exposure to UV radiation, and mobility. However, with excellent properties, HDPE or XLPE tanks can last for more than two decades.
All our tanks are seamless because they are molded as one piece.
No. We manufacture tanks made of polyethylene. BPA is mainly used in polycarbonates and epoxies.
