2550 Litre Steel Bunded Imperium® Generator Feed Tank – Atlantis
The Atlantis 2550 litre Imperium® generator feed tank is a robust steel bunded tank for storing and supplying diesel, HVO and compatible fuels to standby and prime-power generators. Built with Atlantis’ own Imperium® technology, it combines precision tank design with efficient British manufacturing for a well-engineered, compliant generator feed solution.
The inner tank holds the fuel while the steel outer bund provides secondary containment, in line with the Control of Pollution (Oil Storage) (England) Regulations 2001 and devolved equivalents. Every tank comes with Atlantis’ unique removable drop tube, so the foot valve and strainer can be replaced easily if blocked by sludge, reducing maintenance costs and downtime.
