Cube fuel tanks are characterized by their cubic or rectangular prism shape. Steel, aluminum, or composite materials are commonly used for their construction, providing strength and durability.

The tanks usually have access points, including openings for filling, vents, and outlets. These are strategically placed for ease of use and efficient fuel management.

Cube fuel tanks are often employed in backup power systems, such as generators for commercial buildings or data centers. Their modular design facilitates easy integration with generator systems.

Common sizes of cube fuel tanks range from a few hundred to several thousand gallons where they find application in a variety of industries, including:

  • Telecommunications
  • Data Centers
  • Construction
  • Manufacturing
  • Emergency Power Systems
  • Agriculture

Advantages of Cube Style Fuel Tanks

While there are some rules to follow in using cube fuel tanks, they prove to be a flexible and efficient choice for various modern uses.

Enhanced Security Features

Many cube fuel tanks are designed with lockable cabinets that house crucial components like fuel dispensing systems, control panels, and access points. 

They may also incorporate integrated locking mechanisms for the main access points, such as fill ports, vents, and dispensing outlets. 

These locking systems prevent tampering and unauthorized access to the fuel storage system.

Stability and Environmental Safety Benefits

Cube fuel tanks typically have a broad base that evenly distributes the weight of the fuel throughout the tank. In sensitive ecological areas, where the impact of spills can be severe, the stability of cube tanks is crucial. 

Space-Saving Design and Efficiency

Cube fuel tanks have a smaller footprint compared to traditional cylindrical tanks of similar capacity. The ability to install these tanks in confined spaces makes them suitable for fuel storage in city centers or small industrial facilities where available area is limited.

Stackability for Optimal Space Utilization

Cube fuel tanks, with their cubic or rectangular prism shape, are inherently designed to be stackable. This design allows them to be safely and efficiently stacked vertically, maximizing the use of available vertical space.

Ease of Maneuverability with Forklift Pockets

Forklift pockets are often integrated into cube fuel tanks to facilitate easy loading and unloading of cube tanks onto transport vehicles. 

This is particularly beneficial in environments where the arrangement of fuel storage may need to be adjusted based on changing operational needs.

What Are Cylindrical Fuel Tanks?
