The Atlantis 900-Litre Steel Bunded Imperium® Heating Oil Tank is a British-made storage solution designed for heating oil, kerosene, diesel, hydrotreated vegetable oil (HVO), and other approved fuels. Suitable for both domestic and light commercial use, it combines a robust steel build with modern manufacturing methods, delivering long-term reliability where safety, compliance, and ease of maintenance are essential.
Built with Imperium® Technology
This model is manufactured using Atlantis Imperium® technology, a modular production method that reduces welds, improves tolerances, and enhances corrosion resistance. The result is a stronger, longer-lasting tank that’s easier to inspect, service, and maintain, while keeping manufacturing consistent and cost-effective.
Strong Steel Construction
- Material: High-grade S275 JR structural steel
- Compliance: Built to BS EN 10025-2:2004 and BS 799 Pt5 standards
- Finish: Two-coat anti-rust protective system in Holly Bush Green
- Touch-up paint included for installation scratches
This heavy-duty build means the tank is suitable for daily use in homes, farms, small businesses, and light industrial sites.
Bunded for Environmental Protection
This is a pre-bunded tank, with a secondary containment layer capable of holding 110% of the inner tank’s volume. It protects against leaks or spills and meets UK environmental regulations, including the Oil Storage Regulations (PPG2). A 1.5” bund socket is included for fitting a bund alarm probe, alongside bund vents for pressure control.
Practical Fittings and Access
A removable fittings plate makes servicing simple and future-proofs the tank for upgrades. Standard fittings include:
- 2” fill point with aluminium drip cap & chain
- Spare 2” top socket for accessories
- 1.5” port for a contents gauge
- 1” socket with internal suction pipe
- 1” bottom outlet (front face)
- 2” tank-to-bund vent and 2” bund vent
This modular approach saves installers time and makes maintenance easier across the tank’s lifespan.
