The Grande 68 Aviation Double Wall Tank is purpose-built for secure, aboveground bulk storage and dispensing of aviation fuels such as Avgas and Jet A-1. Designed for airports, airfields, heliports, and remote aviation fueling sites, this tank features aviation-specific construction—stainless steel contact for all fuel surfaces, advanced safety controls, robust double-wall containment, and a modular ISO footprint for seamless global deployment.

Features and Benefits:

• Capacity: Safe fill level of 65,570 litres (17,319 US gallons); total capacity 69,020 litres (18,242 US gallons)
• Aviation-Grade Double Wall Construction: Tank-in-tank design with a 6mm thick GR 304 stainless steel inner tank (all wetted surfaces), plus a 6mm mild steel outer tank for secondary containment—no need for external bunds
• Stainless Steel Fuel Contact: All fuel-contact piping, pump lines, and fittings are GR 304 stainless steel to meet aviation standards and prevent rust or contamination
• Aviation-Specific Systems: Designed and certified for clean, safe, and compliant transfer of Avgas and Jet A-1; includes aviation fuel floating suction (draws fuel from the cleanest part of the tank), overfill protection, and high-level intrinsically safe (Ex-i) alarms as standard
• Emergency and Pressure Venting: Comes with a free vent pipe, emergency vent, and optional pressure/vacuum vent
• Modular ISO Footprint: Built to standard 40-foot shipping container dimensions (12,192mm L x 2,438mm W x 2,896mm H) for rapid global transport, stacking, and installation
• Durability: Pressed corners, reinforced top, and a curved tank roof for ultimate strength, longevity, and efficient water drainage
• Sloped Floor & Sump: Sloping 50:1 floor leading to a collection sump for easy removal of water or particulates, with a sampling cabinet included—critical for maintaining aviation fuel purity
• Pump Bay: Large, secure, lockable and bunded compartment for fueling pumps, meters, electronic controls, and accessories
• Internally Baffled: Dampens liquid movement, improving safety and fuel quality, especially if relocated when not empty
• Paint Finish: Extra-thick 250–300 micron industrial coating in white (custom colors available)
• Statutory Safety: Supplied with all required hazardous material and aviation compliance signage and decals

Compliance and Safety:

• Fully complies with UL 142, ULC-S601-14, and all major FAA/aviation fuel storage regulations for double-walled aviation tanks
• Integral secondary containment ensures leak detection and environmental protection; no need for additional concrete bunds
• Stainless steel inner tank and wetted parts ensure total aviation fuel purity and legal compliance
• Each tank is air pressure tested at the factory prior to delivery for leak-tightness, with supporting compliance documentation

Suitable For:

• Airports, heliports, commercial and remote airfields
• Aviation fuel farms, offshore aviation bases, or any operation demanding compliant, contaminant-free, and high-purity Avgas or Jet A-1 storage and dispensing
