The Grande 40 Aviation Double Wall Tank is engineered for secure, aboveground bulk storage and dispensing of aviation fuels like Avgas and Jet A-1. Built for airports, airfields, heliports, and demanding remote or commercial fueling bases, this tank features aviation-certified safety design, premium stainless steel fuel-contact components, and a modular ISO container footprint for effortless transport and installation.

Features and Benefits:

• Massive Capacity: Safe fill level typically in the 35,000–45,000 litre range—confirm your exact aviation requirement with Unity Fuel Solutions; the Grande Aviation tank range offers models up to 107,400 litres.
• Aviation-Grade Double Wall Construction: A “tank-in-tank” design using 6mm GR 304 stainless steel for the entire inner tank and all wetted fuel-contact parts, combined with a 6mm mild steel outer tank for full integral secondary containment—no external bunds needed.
• 100% Stainless Steel Fuel Contact: All internal tank surfaces, fittings, lines, and piping are GR 304 stainless steel, ensuring zero rust, contamination, or fuel purity risk for Avgas or Jet A-1.
• Aviation Fuel Specific: Designed, certified, and delivered outfitted for aviation fuel safety, with features like floating suction (for drawing from the cleanest part of the tank), fuel sampling cabinet, and sloped tank floor and sump for easy particulate/water removal.
• Advanced Safety: Intrinsically safe (Ex-i) high-level alarms and robust overfill prevention system, aviation-caliber emergency venting, updraft/pressure vent pipe, and complete aviation spill protection.
• Modular ISO Footprint: Built on a standard 40-foot container base (about 12,192mm L x 2,438mm W x 2,896mm H) for rapid global logistics, stacking, and easy on-site setup—no heavy installs needed.
• Durable Build: Pressed corners, reinforced top, and a curved tank roof for optimal durability, weather protection, strength, and drainage.
• Internally Baffled: Reduces liquid movement for in-use safety and structural longevity.
• Premium Finish: Industrial-grade 250–300 micron white coating as standard (custom color options available).
• Pump Bay: Lockable, bunded, and weatherproof compartment for aviation-grade fueling pumps, meters, filtration, and accessories—large and secure.
• Statutory Signage: Supplied with all required hazardous material decals and regional aviation compliance labels.

Compliance and Safety:

• Fully meets or surpasses all UL 142, ULC-S601-14, and FAA/aviation industry storage standards for double-walled aviation tanks.
• Integral double-wall containment eliminates the need for external bunds or additional concrete containment; includes leak detection monitoring in the interstitial space.
• Stainless steel fuel-contact design ensures full aviation fuel purity and regulatory adherence.
• All tanks are air pressure tested for leak-tightness prior to shipment and fully documented for compliance.

Suitable For:

• Airports, heliports, commercial and remote airfields
• Offshore aviation support bases and aviation fuel farms
• Any operation requiring secure, contaminant-free, and compliant Avgas or Jet A-1 storage and refueling
