The Bloc 5000 DEF Double Wall Tank is engineered for the secure, compliant storage and dispensing of Diesel Exhaust Fluid (DEF) in demanding environments. Its modular, cube-style design provides robust defense against contamination, environmental exposure, and spill risks, making it ideal for construction, fleet operations, agriculture, and any application relying on DEF.

Features and Benefits:

• Capacity: Safe fill level approximately 5,000 litres (confirm with Unity Fuel Solutions for precise volume)
• DEF-Grade Construction: Double-walled—an internal tank of Grade 304 stainless steel lined with a thermal insulation barrier for DEF purity and temperature control, plus a tough mild steel outer wall for integral secondary containment
• Secure Pump Bay: Lockable, recessed pump cabinet at the front stores dispensing accessories and electronics safely
• Dimensions & Weight: Large cube-style tank footprint designed for maximum on-site stability (contact Unity Fuel Solutions for exact specifications)
• Forklift Pockets & Lifting Lugs: Forklift points and certified tie-down/lifting lugs in all corners for easy transport and installation
• Internal Access: Removable lids allow for safe and simple internal tank cleaning and maintenance

Compliance and Safety:

• Certifications: Exceeds UL-142, ULC-S601-14, and (where required) UN-31-A/Y compliance—ensuring you meet all key North American regulatory standards for DEF storage
• Leak Containment: Double-wall design forms a secure interstitial space for leak detection, eliminating the need for an external bunded wall
• DEF-Only Contact: All wetted surfaces (internal tank, piping, and fittings) are Grade 304 stainless steel, ensuring rust- and contamination-free DEF handling
• Overfill Protection: Mechanical overfill prevention valve is standard; electronic overfill alarms and tank gauges are available as options
• Security: Heavy-duty lockable lids and security features protect both your DEF and dispensing hardware from tampering or weather

Design and Installation:

• Modular and Mobile: Place-fill-and-pump setup allows for rapid deployment with minimal site preparation
• Thermal Insulation: DEF compartment lined with an insulation barrier to maintain fluid quality in a range of climates
• Flexible Dispensing: Sectional manway cut-outs accommodate custom hose routing for equipment like generators or external DEF dispensers
• Durable Finish: Exterior finished with premium-grade paint (white as standard, other colours on request) to resist corrosion and UV exposure

Suitable For:

• Construction and civil engineering sites
• Trucking, logistics, and fleet fueling depots
• Agriculture and mining operations
