All of our bulk fuel tanks are fully bunded, meaning they include an integrated catchment area (a bund) between the steel casement holding the fuel and an outer steel layer. This outer layer provides mechanical protection against damage and potential spillage. The space between the inner and outer steel is designed to hold 110% of the bulk tank’s capacity, offering superior safety and durability compared to plastic alternatives. This ensures a more robust, long-lasting fuel system. The bund area should remain dry (unless there’s a leak), and ideally be equipped with an electronic bund alarm to detect fuel leaks. Installing a manhole or inspection chamber in the bulk fuel tank is recommended for service and maintenance, as well as fitting additional components for future use.

Most of our diesel generators, ranging from 20kVA to 700kVA, come with an integrally bunded fuel tank or a bund tray as part of the skid base frame. Typically, these integral fuel tanks offer a minimum of 8 hours of runtime at full load.

Clients often require a higher fuel capacity for specific projects such as hospitals, data centres, and water treatment facilities. In such cases, fuel must be safely transferred from the bulk tank to the generator using a fuel transfer system. This system typically includes a small pump, a fuel pipe arrangement, a fuel pump control panel, and motorised valves.

As part of our Projects package, ATA can design, manufacture, install, and supply a wide range of bulk fuel storage tanks that comply with current environmental regulations, including stainless steel double-skinned fuel pipes.
