Compartment Tanks are designed to store multiple grades of product, or different types of products, in the same tank. This safe, economical alternative allows you to create multiple fuel storage compartments without having to install separate tanks for each product. They are available with single or double bulkheads and are ideal for storing multiple grades of gasoline. Diesel and biodiesel blends can be stored in the same tank. Advantages include easier installation, requires less space, reduced shipping, excavation and insurance costs.
