IES’s rectangular diesel fuel storage tanks provide a practical solution when an on-ground tank is too large or an overhead tank is not viable. These tanks are available in single-skin and self-bunded (double-wall) varieties, making them suitable for a range of indoor and outdoor applications. Common uses include storage of diesel, oil, and petroleum products, often as day tanks or for generator systems. Designed for strength and durability, the tanks feature protective coatings and fittings to meet customer and industry code requirements. Standard sizes range from 100 to 2,000 liters, with the ability to custom-build larger sizes as needed. The tanks come equipped with features like calibrated dipsticks, valves, vents, and drain fittings to facilitate safe and efficient fuel storage and handling. Manufactured to comply with relevant Australian standards, IES’s rectangular tanks offer a cost-effective, flexible, and code-compliant fuel storage solution, particularly in space-constrained environments.
