AGI Westeel’s ULC S601 and UL142 (with optional ULC S655 and UL 2088 FIREGUARD® upgrade) Vacu-Vault® Dual Wall Aboveground Storage tanks have a vacuum drawn between the primary and secondary tank to confirm tank integrity. Easy to use and install, this unique design provides cost-effective protection against costly and environmentally damaging leaks or ruptures.

Best of all, it’s manufactured by AGI Westeel to meet or exceed all national environmental and hazardous liquids regulations and provide years of worry free service.

Vacu-Vault® sizes range from 1,300L to 120,000L and come with a wide variety of common options and accessories. Each tank is factory-tested for days to ensure a stable vacuum prior to shipment. Options for monitoring the interstitial space include the supplied gauge as well as numerous third party external vacuum monitors. The Vacu-Vault® is a premium tank relative to the Fuel-Vault®, but it offers unsurpassed peace-of-mind when it comes to the integrity of your tank and the fragility of the environment.
