The Grande 90 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. Designed for airports, heliports, commercial airfields, and remote aviation sites, this tank features specialized double-wall construction with aviation-certified stainless steel fuel-contact surfaces and a modular ISO container footprint for straightforward global deployment.

Features and Benefits:

• Massive Capacity: Safe fill level typically around 90,000 litres (confirm your specific application requirements with Unity Fuel Solutions; GRANDE aviation tanks are available up to 107,400 litres)
• Aviation-Grade Double Wall Design: “Tank-in-tank” system featuring a 6mm GR 304 stainless steel inner tank (all wetted surfaces) with a 6mm mild steel outer tank for robust integral secondary containment—no external bunding required
• Absolute Stainless Steel Fuel Contact: All internal tank surfaces, pump lines, piping, and fittings are GR 304 stainless steel to ensure fuel purity and prevent rust or contamination—meets all aviation fuel standards for Avgas/Jet A-1
• Aviation-Specific Safety Systems: Includes floating suction (draws fuel from the cleanest part of the tank), advanced overfill protection alarm, intrinsically safe (Ex-i) high-level alarm, and aviation-compliant venting as standard
• Modular ISO Container Footprint: Constructed to a standard 48-foot container format for cost-effective transport, easy stacking, and rapid site installation
• Robust, Weatherproof Build: Pressed corners, reinforced top, and a curved tank roof for long-term durability and drainage—even in harsh climates
• Internally Baffled: Minimizes liquid movement, boosting in-use safety and structural stability during any relocation or major refueling events
• Premium Industrial-Finish: Extra-thick 250–300 micron industrial-grade white (or custom) coating provides maximum weather resistance and corrosion protection
• Secure Pump Bay: Large, lockable, fully bunded, and weatherproof compartment for aviation-grade fueling pumps, meters, filtration, and electronic dispensing systems—protected and accessible
• Maintenance Friendly: Dual manways, sloped floor to collection sump, separate sampling cabinet, updraft vent, calibrated dipstick, all required aviation/hazard signage as standard

Compliance and Safety:

• Fully certified to UL 142, ULC-S601-14, and all FAA/aviation industry standards for aboveground, double-walled tanks
• Stainless steel fuel-contact design eliminates contamination risk and upholds aviation safety regulations
• Integral double-wall containment with interstitial monitoring—no need for external concrete bunding
• Each tank is factory air pressure tested for leak-tightness and delivered with full compliance documentation/signage

Suitable For:

• Major airports, heliports, commercial and remote airfields
• Aviation fuel farms and offshore support bases
• Any operation demanding secure, contaminant-free, regulation-compliant Avgas or Jet A-1 storage and bulk dispensing
