The ZCL | Xerxes Advantage

Discover the benefits of our advanced fluid storage technology and product expertise for enhancing system design and extending project lifecycle performance.

100% Premium Resin and Glass (No Fillers)
ZCL | Xerxes tanks are constructed of 100% premium resin and glass. We use no fillers or recycled materials, which sets us apart from many tank options. We maintain our standard of excellence by performing verification tests on our resin and glass to ensure that only high-quality materials are used in the manufacturing process.
Corrosion Resistance Inside and Out
ZCL | Xerxes tanks are made of fiberglass, which means they are inherently resistant to corrosion. Because they are corrosion-resistant inside and out, you’ll have the peace of mind of choosing a tank that helps preserve and protect the environment. You’ll also enjoy a lower cost of ownership than with steel and concrete tanks, which corrode over time and require maintenance.
Flexible Design & Installation Options
ZCL | Xerxes fiberglass tanks come in a wide range of sizes and designs – along with numerous accessories and monitoring options – to meet a variety of site and regulatory requirements, for both underground and aboveground installations. Contact us today to discuss your next project.
