Arctic King ™

Cold weather fuel bladder tanks designed to withstand harsh Arctic conditions

About the Arctic King

The Arctic King collapsible fuel bladder tank is specifically designed for liquid fuel storage in sub-zero climates to -50F or -46C. Constructed from a proprietary high-durability fabric unique to SEI Industries, this fuel bladder tank has excellent UV and hydrolysis resistance for a longer life expectancy than any other urethane collapsible fabric tank in the arctic. With all these features, plus its one-way vent system to handle deep snowfalls, the Arctic King is ideally suited for even the most extreme arctic conditions.

These bladder tanks combine portability and versatility with economy and are available in a full range of sizes from 250 USG (1000 L) to 33,000 USG (125,000 L). By connecting multiple King pillow tanks together, through a manifold system, you can create a cost-effective tank farm with unlimited capacity.

About the Arctic Fabric

Arctic King tanks are constructed from fabric which was purpose-engineered by SEI for above-ground storage of fuels in arctic climates at remote sites. The fabric has a low cold-crack temperature below -50F or -46C. It was developed to withstand long duration fuel exposure. Further, it meets the CAN/CSA B-837-14 standard for collapsible fabric storage tanks (bladders). The Arctic fabric we use exceeds all US military specifications and provides a number of advantages that ultimately help to preserve fuel quality and extend equipment life and safety.
