Multi-compartment fiberglass storage tanks are a popular choice when storing two or three grades of fuel in a single tank within separate compartments. In many cases, these tanks provide overall savings vs. two or three separate tanks. Available in capacities up to 40,000 gallons, Xerxes multi-compartment tanks come standard with double-wall bulkheads.

Triple-wall fiberglass storage tanks provide customers with the most advanced level of security when secondary containment isn't enough. A small number of jurisdictions regulate it. A triple-wall tank is available in sizes up to 40,000 gallons and offers four monitoring options.

TRUCHEK® Continuous Monitoring – When you order a Xerxes double-wall tank with the TRUCHEK option, the interstice between the two tank walls is factory-filled with calcium-chloride fluid that also partially fills a tank-top reservoir. This innovative design creates a hydrostatic pressure throughout the interstice, thereby monitoring both tank walls on a continuous basis. An electronic probe placed in the tank’s reservoir alarms when the fluid level falls below or rises above the acceptable level. The alarm system is compatible with SCADA communications systems for 24/7 monitor reporting. TRUCHEK also provides a precise and reliable method to perform a tank-tightness test that meets the strict NFPA 329 criteria.
