The Grande 55 Aviation Double Wall Tank is engineered for ultra-high-capacity, aboveground bulk storage and dispensing of aviation fuels such as Avgas and Jet A-1. Built for airports, heliports, airfields, and remote or high-throughput fueling bases, this aviation-grade tank features robust stainless steel fuel-contact, advanced aviation safety systems, and a modular ISO container footprint for seamless global deployment.

Features and Benefits:

• Massive Capacity: Safe fill level typically in the 50,000–60,000 litre range—confirm your exact requirements with Unity Fuel Solutions; Grande Aviation tanks are available in multiple ISO formats up to 107,400 litres.
• Aviation-Grade Double Wall Construction: “Tank-in-tank” system with a 6mm thick GR 304 stainless steel inner tank and mild steel 6mm outer tank delivers total secondary containment—no external bunding required for any compliant operation.
• 100% Stainless Steel Fuel Contact: All wetted parts—including the inner tank, pump lines, piping, and fittings—are GR 304 stainless steel to protect against contamination and rust; designed specifically for Avgas and Jet A-1 purity.
• Aviation Safety Features: Floating suction (draws fuel from the cleanest part of the tank), advanced overfill protection alarm, intrinsically safe (Ex-i) high-level alarm, and emergency/pressure venting systems are standard.
• ISO Container Footprint: Constructed on a standard 48-foot ISO shipping container base for rapid transport, stacking, and easy on-site installation.
• Rugged, Weatherproof Build: Pressed corners, reinforced top, and a curved tank roof maximize long-term durability and optimal drainage, even in harsh climates.
• Internally Baffled: Minimizes liquid movement, boosting safety and stability during relocation or transport.
• Pump Bay: Secure, lockable, and bunded compartment for fueling pumps, meters, filtration hardware, and electronic controls—spacious, accessible, and weatherproof.
• Sloping Floor & Sump: Internal floor slopes toward a collection sump for easy removal of water and particulates, routine sampling, and ongoing aviation-grade QA/QC sampling cabinet included.
• Paint Finish: Industrial-grade 250–300 micron white (custom color options available) for maximum corrosion resistance.
• User-Friendly: Dual manway access points, in-built ladder/platform, updraft vent pipe, interstitial leak monitoring, and easy maintenance design.
• Statutory Safety: Supplied with all required hazardous material and aviation compliance decals.

Compliance and Safety:

• Fully meets or exceeds all UL 142, ULC-S601-14, and FAA/aviation industry requirements for aboveground double-walled tanks.
• Integral secondary containment eliminates need for traditional site-built bunding; leak detection monitoring is built in.
• Stainless steel tank and fuel lines ensure complete fuel integrity—critical for Avgas and Jet A-1.
• Each tank is air pressure tested for leak-tightness prior to shipping, with compliance safety signage and documentation supplied.

Suitable For:

• Commercial airports, heliports, private and remote airfields, offshore/industrial aviation fueling bases, and any operation demanding compliant, high-purity Avgas or Jet A-1 storage
