The Grande 12 DEF Dual Compartment Double Wall Tank is crafted for secure, aboveground storage and dispensing of Diesel Exhaust Fluid (DEF) together with a second compatible fluid (diesel, lubricant, or coolant)—all within a compact, regulation-ready, self-bunded ISO container. Its dual-compartment construction offers maximum flexibility, purity, and full compliance for demanding commercial, industrial, and remote fueling or fleet sites.

Features and Benefits:

• Dual Compartment Storage: Fully isolated compartments for DEF and a second fluid—store both in one ISO tank footprint for space efficiency, zero cross-contamination, and simple site logistics.
• DEF-Compatible Materials: All components in contact with the DEF compartment are DEF (urea) approved for product purity and system lifespan.
• Double-Wall Protection: Each compartment features a primary mild steel tank inside a mild steel secondary containment tank—integral double-wall design eliminates need for external bunds.
• Compact ISO Footprint: Built to standard 8-foot (approx. 2,991mm x 2,438mm) container specs for easy global logistics, fast stacking, and simple installation in small spaces.
• Capacity: Safe fill level up to 11,240 litres total (confirm your ideal compartment split at order—custom configurations available).
• Internally Baffled: Dampens liquid movement in both compartments for greater operational safety, especially during relocation.
• Secure Pump Bays: Spacious, lockable, and bunded cabinets for DEF (with heating kits if required) and fuel/lube pumps—weatherproof and secure from tampering.
• User-Friendly Maintenance: Integrated ladder/work platform, dual manway tank entries, updraft vents, calibrated dipsticks, and visible fill points for simple use and inspection.
• Professional Paint Finish: Industrial-grade 250–300 micron white coating (other colors by request) for maximum corrosion and weather protection.
• Flexible Dispensing Options: Compatible with DEF bulk kits, heated DEF lines, filtration, metering, management systems, and a wide array of fuel/lube delivery options.
• Plug-and-Play Installation: Arrives pre-built for rapid setup—just position, fill, and pump.

Compliance and Safety:

• Meets or exceeds UL 142, ULC-S601-14, and all major Canadian and US standards for double-walled, compartmentalized tanks.
• Complete integral secondary containment for both compartments with built-in leak detection, bunded dispensing, interstitial monitoring, and overfill protection.
• Each tank factory pressure tested for leak-tight performance prior to shipping.
• Delivered with all required hazardous material signs and compliance decals.

Suitable For:

• Fleet fueling depots, construction sites, mining, farms, industrial operation yards, and remote installations—any job that needs space-saving, safe, compliant DEF plus split product storage.
