The Grande 20 Aviation Double Wall Tank is engineered for secure, aboveground bulk storage and dispensing of aviation fuels such as Avgas and Jet A-1. Built for airports, heliports, airstrips, and remote fueling bases, this tank features robust aviation-specific safety design, stainless steel contact surfaces, and a modular ISO container footprint.

Features and Benefits:

• Capacity: Safe fill level of approximately 20,000 litres (confirm exact SFL for aviation fuel with the supplier—the Grande Aviation line covers a range 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 wall for total secondary containment—no external bunding required
• Stainless Steel Contact: All wetted parts—inner tank, fuel lines, piping, and fittings—use GR 304 stainless steel, fully compliant with aviation fuel safety standards to prevent contamination
• Aviation Fuel Ready: Clean, safe, and compliant storage of Avgas and/or Jet A-1
• Floating Suction: Draws fuel from the cleanest part of the tank, reducing sediment pick-up risk (Grande Aviation feature)
• Overfill Protection: Advanced overfill alarm system and high-level, intrinsically safe (Ex-i) alarms for optimal safety (Grande Aviation standard)
• Emergency and Pressure Venting: Supplied with free vent pipe, emergency vent, and optional pressure/vacuum vent
• ISO Modular Footprint: Dimensions match a standard 20-foot shipping container (6,058mm L x 2,438mm W x 2,896mm H) for rapid global transport, easy stacking, and simple on-site setup
• Durable Build: Pressed corners, reinforced top, curved roof for weather protection and strength
• Sloping Floor & Sump: Sloped to a collection sump for easy water or particulate removal, plus a sampling cabinet—critical for aviation quality assurance
• Pump Bay: Lockable, bunded compartment for fueling pumps, meters, electronics, and all accessories—weatherproof, secure, and aviation grade
• Paint Finish: Industrial-grade 250–300 micron white (custom colours available)
• Internally Baffled: Minimized liquid movement for in-transit safety and structural integrity
