As North America continues to explore, produce and deliver domestic oil and gas to a world market, the delivery of these

petroleum resources has created a boom in the development and construction of pipelines, pumping stations and rail

transfer facilities. These facilities typically require liquid storage for emergency spills or for routine maintenance activities,

creating the need for an underground double-wall containment system for product collection. Due to the sensitive nature

of the underground collection of hydrocarbons, Xerxes double-wall, fiberglass continuously monitored storage tanks are a

wise, environmentally safe choice.

Since their introduction in the 1960s, fiberglass underground storage tanks have grown in popularity and today are the

dominant tank choice among fuel retailers and owners of fleet fueling facilities. They frequently replace rusting and

leaking steel tanks, which can be an environmental threat. External corrosion of buried tanks will always be a concern,

but with upstream petroleum products and today’s refined fuels, today internal corrosion protection is often a greater

concern. That’s where Xerxes fiberglass tanks excel: they are not subject to internal microbial corrosion or exterior corrosive

soil environments.

Xerxes historyEstablished in 1979, today Xerxes is part of the ZCL group of companies manufacturing underground and aboveground

fiberglass tanks for a wide range of applications. During the last three decades, we have supplied more than 200,000

underground storage tanks for installations throughout North America. Our tanks are manufactured in six state-of-the-art,

UL-listed North American manufacturing facilities. With a reputation for innovation and high-quality products, Xerxes and

ZCL are recognized as industry-leading brands in both the upstream and downstream segments of the petroleum industry.

Why choose a Xerxes® tank?

Rib Design – Circumferential ribs are an important design element of any fiberglass underground tank, making the geometry of the rib and how it’s incorporated into the tank — important design considerations. In the Xerxes design, with its consistent, high-profile rib structure, ribs are fabricated directly into the tank cylinder – not as a secondary step in the process. This increases the overall strength of the tank and results in a structurally superior product.

Parabeam® Construction – Xerxes utilizes Parabeam, a unique and proprietary three-dimensional glass fabric, to create the interstitial space of a double-wall tank. Parabeam enhances overall structural integrity by creating a bond between the pri-mary and secondary cylinder walls, while providing a free-flowing interstitial space for monitoring capabilities.

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.

TRUCHEK ®

UL-Listed – Xerxes double-wall fiberglass tanks are subjected to third-party material testing, proof-testing and product compatibility testing based on UL1316. This listing has been the North American industry standard for underground petroleum tanks for decades.
