The Grande 75 Aviation Double Wall Tank is engineered for ultra-high-capacity, aboveground bulk storage and dispensing of aviation fuels like Avgas and Jet A-1. Built for airports, heliports, commercial airfields, and demanding remote fueling sites, this tank features aviation-certified double-wall construction, robust stainless steel fuel-contact components, and a modular ISO container design for easy transport and installation.

Features and Benefits:

• Massive Capacity: Safe fill level typically in the 70,000–80,000 litre range (confirm your exact requirements with Unity Fuel Solutions; the GRANDE aviation tanks offer models up to 107,400 litres)
• Aviation-Grade Double Wall Construction: “Tank-in-tank” design with a 6mm GR 304 stainless steel inner tank for all wetted surfaces, plus a 6mm mild steel outer tank for full integral secondary containment—no external bunding required
• 100% Stainless Steel Fuel Contact: All inner tank surfaces, fuel lines, piping, and fittings use GR 304 stainless steel to protect fuel purity and prevent rust or contamination, meeting all aviation storage regulations
• Aviation Fuel Ready: Designed for Avgas and Jet A-1, with floating suction to draw from the cleanest part of the tank and maintain fuel quality
• Overfill and High-Level Alarm System: Advanced overfill protection and intrinsically safe (Ex-i) alarms included for maximum operational safety
• Emergency and Pressure Venting: Supplied with emergency vent, free vent pipe, and optional pressure/vacuum vent for full compliance
• Modular ISO Container Footprint: Built on a 40- or 48-foot ISO container base for streamlined global transport, stacking, and rapid on-site setup
• Durable Build: Pressed corners, reinforced top, and a curved tank roof maximize longevity, strength, and drainage—even in harsh climates
• Internally Baffled: Minimizes liquid movement, boosting in-use safety and structural integrity, especially during relocation
• Secure Pump Bay: Lockable, bunded, and weatherproof compartment for aviation-grade dispensing pumps, meters, filtration, and accessories
• Maintenance Friendly: Dual manway access, sloping floor to collection sump, sampling cabinet, updraft vent, calibrated dipstick, and all required hazardous material signage as standard
• Paint Finish: Extra-thick 250–300 micron industrial-grade white coating (custom colors available)

Compliance and Safety:

• Meets or exceeds UL 142, ULC-S601-14, and all relevant FAA/aviation fuel storage standards for double-walled tanks
• Stainless steel fuel-contact points eliminate fuel contamination risk and uphold strict aviation safety standards
• Self-bunded build provides full integral secondary containment with interstitial leak monitoring
• Each tank is air pressure tested before delivery for leak-tight performance, supported by full compliance documentation

Suitable For:

• Airports, heliports, commercial and remote airfields
• Aviation fuel farms, offshore bases, and any site needing secure, compliant, and pure Avgas or Jet A-1 storage and dispensing
