Double Walled Fuel Tanks

Manufacturers of the highest quality double wall fuel storage tanks, built for protection and convenience

Western Global are proud to manufacture world-renowned double walled fuel tanks. We’ve been meeting the evolving needs of various industries for over six decades, making it our mission to provide safe, secure and environmentally secure double walled fuel storage.

Double wall construction provides numerous advantages over conventional single skin fuel tanks, especially in demanding environments and situations. If you need security, convenience, and protection then look no further than Western Global’s double walled tanks.

Double wall construction explained

We engineer double walled units where the secondary containment is 100% of the inner tank, is built into the tank. With built-in, weather proof containment, we eliminate the need for pans, berms and basins. This dramatically simplifies the cleaning and inspection process, and saves on the cost of cleaning pans to prevent contamination or rainwater accumulation. All pumps and accessories are housed within the contained cabinet, out of the environment and do not need to be assembled on site. Your fuel is also secured behind two steel walls preventing theft and the risk of fuel getting into the environment, which can cost thousands of dollars to clean up.

Double-walled tanks versus single skin / cylindrical (static or trailer)

Double walled tanks offer many benefits over cylindrical and single skin tanks. With single skin tanks you have the additional expense of secondary containment that is needed to catch any spills or drips which can incur labor charges, as well as costing $150 for each pan to be cleaned out. Single skinned tanks also do not have forklift pockets or maneuverability around site or for offloading. These are just some of the reasons that single skinned tanks are slowly being replaced by double walled tanks. 

Cylindrical tanks are typically singled skinned, and even if they are not, the Environmental Protection Agency (EPA) will inspect them regardless. Cube double walled tanks are automatically EPA compliant. With cylindrical tanks, pumps and accessories are housed outside of the tank which makes them prone to theft. The cost of replacing the pump and accessories can be up to $1,000. They are also impacted by the out in the cold and rain which can shorten their lifespan.

Benefits of doubled walled fuel storage tanks

There are numerous benefits of double wall fuel tanks, ranging from environmental to everyday maintenance. Let’s explore these advantages in more detail:

The inspection hatch on Western Global double walled tanks is a feature which helps you maintain and inspect the tank without having to fully take it apart.

When it comes to convenience, our integrally double-walled tanks require minimal site preparation, keeping things simple. This extends the service life of the fuel tanks, which is predicted at over 10-years of reliable operation and income.

Environmental Compliance

Heavy-duty, double‑walled protection

Double walled diesel storage tanks are robust, with the double-walled construction providing protection against extreme weather. This makes them ideal for demanding industries like construction and defense. In an experiment, we hoisted a popular 10TCG model weighing in at over 3,000lbs 80ft in the air and released it to gravity. In the drop, we demonstrated just what our double walled tanks could withstand, with the inner tank maintaining pressure and no spills.

We also supply bunded AdBlue storage tanks, providing complete containment for your diesel exhaust fluid. Read more about our 22DEF or 05DEF tanks.
