The Grande 90 Aviation Double Wall Tank with Pump Bay is engineered for ultra-high-capacity, aboveground bulk storage and dispensing of aviation fuels like Avgas and Jet A-1. Designed and certified for commercial airports, heliports, airfields, and remote aviation sites, this tank features aviation-grade double-wall containment, stainless steel fuel-contact surfaces, advanced pump bay integration, and a modular ISO container footprint for effortless installation and maximum compliance.

Features and Benefits:

• Massive Capacity: Safe fill level typically around 90,000 litres (confirm your application with Unity Fuel Solutions; Grande Aviation tanks are available up to 107,400 litres)
• Aviation-Grade Double Wall Construction: “Tank-in-tank” with a 6mm GR 304 stainless steel inner tank (all wetted surfaces for total purity and rust prevention) and a 6mm mild steel outer tank for robust secondary containment, fully eliminating the need for any external bunding
• Integrated Pump Bay: Large, lockable, fully bunded and weatherproof compartment for aviation-grade fueling pumps, meters, hose reels, electronic controls, and all dispensing and filtration accessories—protected, accessible, and secure
• Absolute Stainless Steel Fuel Contact: Every internal tank surface, pump line, pipe, and fitting is GR 304 stainless steel—ensuring purity and compliance for Avgas or Jet A-1 and preventing any risk of rust or fuel contamination
• Aviation-Specific Safety: Floating suction (draws fuel from the cleanest level), advanced overfill protection alarm, high-level intrinsically safe (Ex-i) alarm, aviation venting, updraft/pressure/vacuum vent (as required)
• Robust, Weatherproof Build: ISO 48-foot modular container footprint (about 12,192mm x 2,438mm x 2,896mm) for transport, simple stacking and deployment, plus pressed corners, reinforced top, and a curved tank roof for structural strength and drainage—even in harsh weather
• Internally Baffled: Damps liquid movement, enhancing safety and stability, including during relocation or major dispensing
• Sloped Floor & Sump: Sloped internal floor directs water or particulates to a collection sump for clean outs; sampling cabinet included for aviation fuel quality checks
• Premium Finish: Industrial-grade 250–300 micron white coating (custom colors available) for weather and corrosion resistance
• Maintenance Friendly: Dual manways, sloped sump, updraft vent, calibrated dipstick, emergency venting, and all necessary compliance decals and signage

Compliance and Safety:

• Fully meets or exceeds all UL 142, ULC-S601-14, and FAA/aviation industry standards for aboveground, double-walled tanks
• Double-wall design includes integral interstitial monitoring for leak detection—no extra containment needed
• All aviation-contact points are GR 304 stainless steel for complete regulatory compliance and maximum purity
• Overfill alarms, bunded pump bay, and statutory safety labels as standard
• Each tank is air pressure tested at the factory for leak-tightness before delivery

Suitable For:

• Major airports, heliports, commercial airfields, aviation fuel farms, offshore support bases, or any operation needing ultra-high-capacity, contaminant-free, regulation-compliant Avgas or Jet A-1 storage and refueling
