The Grande 100 Aviation Double Wall Tank with Pump Bay is purpose-built for ultra-high-capacity, aboveground bulk storage and dispensing of aviation fuels such as Avgas and Jet A-1. Designed for commercial airports, heliports, remote airfields, and major aviation fueling bases, this tank features aviation-certified double-wall containment, premium stainless steel fuel-contact surfaces, a robust integrated pump bay, and a modular ISO container design for maximum compliance, safety, and fast installation.

Features and Benefits:

• Massive Capacity: Safe fill level of approximately 100,000 litres (confirm your application with Unity Fuel Solutions; GRANDE aviation tanks offer models up to 107,400 litres)
• Aviation-Grade Double Wall Construction: “Tank-in-tank” structural design featuring a 6mm GR 304 stainless steel inner tank (all wetted surfaces) and a 6mm mild steel outer tank, providing full integral secondary containment and eliminating the need for external bunding
• Absolute Stainless Steel Fuel Contact: All interior tank surfaces, fueling lines, piping, and fittings are GR 304 stainless steel—ensuring pure, contaminant-free Avgas or Jet A-1 storage and dispensing, fully compliant with aviation fuel standards
• Pump Bay Integration: Large, lockable, weatherproof, and bunded compartment for aviation-grade fueling pumps, meters, hose reels, electronic control systems, and all dispensing and filtration accessories—customizable to your fueling requirements
• Aviation-Specific Safeguards:
• Floating suction draws fuel from the cleanest part of the tank—protecting fuel quality
• Advanced overfill protection alarm and intrinsically safe (Ex-i) high-level alarms
• Sloped tank floor (50:1) guiding all water or particulates to a collection sump for routine removal; sampling cabinet for ongoing QA/QC
• Emergency and pressure venting as standard
• Modular ISO Footprint: Built on a 40- or 48-foot ISO container base (approx. 12,192mm x 2,438mm x 2,896mm) for cost-effective global transport, rapid stacking, and fast, easy site installation
• Rugged, Weatherproof Build: Pressed corners, reinforced top, and a curved roof provide strength and effective water runoff; extra thick 250–300 micron industrial-grade white coating (custom colors available)
• Internally Baffled: Dampens liquid movement for operational stability and safety
• Maintenance Friendly: Dual manway access, updraft vent, calibrated dipstick, easy clean-out and sampling

Compliance and Safety:

• Fully certified to UL 142, ULC-S601-14, and FAA/aviation storage regulations for aboveground, double-walled tanks
• Integral secondary containment with built-in leak detection and interstitial monitoring—no additional bund wall required
• All fuel contact surfaces made from stainless steel as required by law to prevent contamination and ensure long-term fuel quality
• Each tank factory air pressure tested for leak integrity prior to delivery
• Supplied with full statutory and regulatory safety signage/documentation

Suitable For:

• Major airports, heliports, commercial and remote airfields
• Aviation fuel farms, offshore platforms, or any operation requiring high-volume, secure, regulation-ready Avgas or Jet A-1 storage and dispensing
