Diesel Exhaust Fluid (DEF) Tanks
Xerxes diesel exhaust fluid (DEF) tanks are designed to meet the growing demand for secure and long-lasting DEF storage solutions. Made from premium fiberglass, these tanks provide natural corrosion resistance, eliminating the need for coatings, linings, or frequent maintenance. Their space-saving underground design ensures optimal storage capacity, while built-in hydrostatic monitoring offers continuous protection and security.
With capacities of up to 50,000 gallons and compatibility with a wide range of DEF-compliant accessories, Xerxes DEF tanks deliver exceptional performance, meeting or exceeding industry standards for safe and efficient DEF storage.
Important Features
Fiberglass Construction for DEF Compatibility
Fiberglass is the ideal material for DEF storage, as it resists corrosion without requiring protective coatings or special equipment. Unlike carbon steel, which degrades when exposed to DEF, fiberglass ensures safe, long-term storage with minimal maintenance.
Space-Saving Underground Design
Xerxes DEF tanks offer significant space-saving benefits by being installed underground, reducing the need for large aboveground structures. Their multicompartment option further optimizes storage, allowing multiple products to be securely stored within a single tank.
Structural Integrity and Strength
These cylindrical tanks feature rounded end caps and integrally manufactured fiberglass ribs that provide structural reinforcement, similar to I-beams. The patented 3D Parabeam® glass fabric strengthens the tank walls, enabling them to handle underground stresses and heavy H-25/HS-25 axle loads.
Industry-Compliant with Long-Term Reliability
Xerxes DEF tanks meet or exceed standards like PEI/RP1100, ISO 22241, and ANSI/CAN/UL/ULC 1316:2018. They undergo rigorous testing for urea DEF storage and come with a 30-year limited warranty, ensuring reliable performance and long-lasting peace of mind.
