The Bloc 2500 DEF Dual Compartment Double Wall Tank delivers safe, compliant, and efficient dual fluid storage—ideal for Diesel Exhaust Fluid (DEF) and diesel fuel—on jobsites where reliability and environmental protection matter. Purpose-built for demanding environments in transportation, agriculture, mining, and fleet operations, this tank combines innovative engineering with plug-and-play versatility.

Features and Benefits:

• Capacity: Diesel compartment safe fill level approx. 2,500 litres (660 US gallons); DEF compartment capacity varies by model—confirm with Unity Fuel Solutions for precise DEF compartment volume (commonly paired with 400–660 US gallons).
• Dual Compartment Design: Separate internal tanks for diesel and DEF, each with individual manways and access, allowing secure storage and dispensing without risk of cross-contamination.
• Double-Walled Security: Diesel tank features a double-wall steel structure (5mm primary inner, 3mm secondary outer for diesel), while the DEF compartment uses Grade 304 stainless steel for all wetted surfaces, lined with a thermal insulation barrier to protect DEF integrity and prevent contamination.
• Baffled/Internal Construction: Each compartment is baffled to reduce liquid movement, improving safety and stability during transport or relocation, even when partially filled.

Compliance and Safety:

• Certifications: Meets UL-142, ULC-S601-14, and UN-31-A/Y compliance as standard (satisfying Canadian, US, and international safety requirements for double-wall tanks storing DEF and diesel).
• Leak Containment: Integral secondary containment with interstitial monitoring points—no external bund required.
• Security and Maintenance: Both tank manways are accessible and removable for safe cleaning and inspection; both are secured under heavy-duty, lockable lids. Recessed, lockable pump cabinet and spill box for each compartment protects dispensing equipment.
• Safety Labels and Decals: Supplied with all required DEF and diesel labeling for full regulatory compliance and proper hazard identification.
• DEF Integrity: Stainless steel construction for all DEF-contacting components eliminates corrosion risk, and a thermal insulation barrier ensures DEF stability in changing environments.

Design and Installation:

• Modular and Mobile: Cube-style, freestanding tank with forklift pockets and certified lifting/tie-down points at each corner for quick transport and simple site installation.
• Flexible Dispensing: Multiple port fittings for both fluids, easy access for DEF and diesel pumping equipment, and curved roof for water drainage.
• Ready for Commissioning: Plug-and-pump setup allows for rapid installation with minimal site preparation. Sectional cut-outs on side manways facilitate customized hose routing to external requirements, such as generator fueling.
• Exterior Finish: Premium 250–300 micron white paint as standard (custom colours available to order), ensuring long-term durability and corrosion resistance.

Suitable For:

• Fleet fueling depots, construction, mining, agriculture, logistics, and any business requiring safe, efficient, and compliant dual storage and dispensing of diesel and DEF on one compact footprint.
