The Atlantis 1350-Litre Steel Bunded Imperium® Heating Oil Tank is designed for safe and dependable storage of heating oil, kerosene, diesel, HVO, waste oils, and more. Suitable for both domestic and light commercial use, it combines durable steel construction with practical features that make installation and maintenance straightforward.
Imperium® Technology – A Smarter Way to Build Tanks
This model is manufactured using Imperium® Technology, Atlantis’s modular production method that reduces welds, improves tolerances, and enhances corrosion resistance. The result is a stronger, more consistent tank that’s easier to inspect, service, and maintain. Built from S275 JR structural steel and manufactured to meet strict British Standards, this tank delivers excellent durability and long-term performance.
Bunded for Safety and Compliance
The 1350L tank is pre-bunded, providing a built-in secondary containment system that holds 110% of the inner tank’s capacity. This dual-layer protection minimises the risk of leaks and spills reaching the environment. The bund is vented and includes a socket for fitting a bund alarm probe if required.
Practical Features for Everyday Use
A removable fittings plate houses all the main connections, making checks and upgrades easy. Standard fittings include a 2” fill point with aluminium drip cap, a spare 2” top socket, a 1.5” port for a contents gauge, and a 1” socket with internal suction pipe. A 1” bottom outlet is fitted as standard, along with dedicated vents for both the tank and the bund.
