The Bloc 400 DEF Double Wall Tank is engineered specifically for the compliant, secure storage and dispensing of Diesel Exhaust Fluid (DEF). Designed to protect DEF from environmental factors and contamination, it suits all applications where DEF is required—such as construction, fleet operations, agriculture, and remote locations.

Features and Benefits:

• Capacity: Safe fill level of 400 gallons (approx. 1,500 litres based on model variations, confirm exact capacity for your region)
• DEF-Grade Construction: Double-walled tank design with an inner tank made from high-grade GR 304 stainless steel, lined with a thermal insulation barrier for temperature protection, and a tough mild steel outer wall for robust secondary containment
• Dimensions & Weight: Compact cube style for space-efficient site use; inquire with Unity Fuel Solutions for exact specifications

Compliance and Safety:

• Certifications: Meets UL-142, ULC-S601-14, and (depending on region) UN-31-A/Y compliance standards, ensuring full regulatory safety for DEF handling and storage
• Leak Containment: Double-wall system provides an integral interstitial space for leak detection and prevents contamination of DEF—no external bund required
• DEF-Specifics: All wetted components (tank, piping, fittings) are GR 304 stainless steel to eliminate risk of rust or contamination in DEF
• Security & Maintenance: Both tank manways are accessible and removable for safe internal tank cleaning and maintenance; lockable recessed pump cabinet and spill box protect DEF dispensing equipment
• Thermal Protection: Integrated insulation barrier maintains DEF quality in variable climates, supporting year-round fluid integrity

Design & Installation:

• Modular & Mobile: Forklift pockets and certified lifting/tie-down points at each corner enable quick relocation and installation
• User-Friendly: Plug-and-pump place-fill-and-pump commissioning allows rapid setup with minimal site work; curved roof prevents water pooling
• Flexibility: Sectional manway cut-outs permit flexible hose routing to meet different equipment or generator requirements

Suitable For:

• Construction, mining, logistics, agriculture, fleet fueling depots, emergency services, and any application requiring secure, clean DEF storage and dispensing
