At Westeel we work with partners across a variety of industries to design and build fuel storage tanks that meet the unique combination of price and features of each industry.  Through this process we've recognized that some users need a no-frills, code compliant, dual wall tank that is ULC listed, and free of leaks. The result of this demand is the Opti-Vault™.
