STORAGE
Vertical Bulk Storage Tanks
1,500 to 20,000 gallon capacities, 250 psig MAWP, vacuum-jacketed with perlite or MLI insulation for liquid nitrogen, oxygen and argon service.
AquaVBC designs and manufactures vacuum-insulated storage tanks, dewars and transfer systems for liquid nitrogen, oxygen and argon service. From single-vessel installations to full turnkey cryogenic plants — engineered, welded and tested by our team.
Every vessel we ship is designed around one goal: keep the cold in, keep the boil-off out, and keep operators safe. That means multi-layer super-insulation, high vacuum sustained under load, and welded joints that we back with our own field service.
Multi-layer insulation combined with sustained high vacuum keeps boil-off rates below 0.35% per day on our standard bulk tanks — well under industry norms.
Pressure vessels designed and stamped to ASME BPVC Section VIII Division 1, with full material traceability and radiographic weld inspection.
We do not walk away after delivery. Every system ships with commissioning support, an operator training session and a 10-year vacuum warranty.
Non-standard footprint, unusual pressures, tight schedule? Our in-house design team handles one-off configurations that catalog suppliers turn away.
Machined, welded and tested in our Rifle, CO facility. Domestic steel, domestic labor, direct lines to the engineers on your project.
Standard vessels typically ship in 6–10 weeks. Rush production available for outage and emergency-replacement scenarios.
AquaVBC was started in 2011 by Rich Dunning after two decades welding pressure vessels for the oil-and-gas and industrial-gas markets in the Rockies. What began as a repair shop for third-party dewars has grown into a full manufacturer serving customers in food processing, biotech, aerospace propulsion testing, semiconductor fabs and university research labs across North America.
Today our 28,000-square-foot facility outside Rifle houses CNC machining, in-house polishing, ASME-certified welding, a dedicated vacuum-bake tunnel and full hydro / helium leak-test bays. Every vessel that leaves the door has been pressure-tested, evacuated, and helium-leak-checked below 1×10⁻⁹ mbar·L/s.

A short list of what we make most often. If you need something else, we build to order.
1,500 to 20,000 gallon capacities, 250 psig MAWP, vacuum-jacketed with perlite or MLI insulation for liquid nitrogen, oxygen and argon service.
Rolling 180-, 230- and 450-liter dewars plus 500–1,500 gallon MicroBulk skids for on-site fill and low-throughput customers.
Rigid and flex VIP with bayonet connections. Field-routed transfer lines, phase separators and end-use manifolds engineered per site drawing.
Vapor- and liquid-phase sample storage from 35 L to 800 L. Auto-fill control, alarm contacts, high-density racking for straws and vials.
Belt widths from 24" to 60" for cryogenic freezing of proteins, produce, ready-meals and nutraceutical ingredients. Turnkey install.
Vacuum re-pull, valve rebuild, relief re-cert, gauge calibration, and pipe extension work for existing installations of any make.
IQF freezing, cryogenic grinding, MAP packaging and beverage nitrogen dosing.
Cell-line storage, vaccine cold-chain, and pilot-scale API cryomilling systems.
Test-stand LN₂ supply, engine chill-down loops and vacuum-jacketed fill lines.
Cleanroom N₂ supply, sample cooling, and university physics-lab installations.
"We replaced a 6,000-gallon tank on a two-week outage window and AquaVBC hit it. The new vessel has been holding a lower boil-off number than the OEM spec on our old one."
"Their engineering team actually reads the drawings. We got a VIP run installed at our test cell without a single field change order, which is a first for us."
"Rich and his crew retrofitted our lab freezers with auto-fill controllers and the sample-loss incidents dropped to zero. Simple, well-built, no drama."
Most quotes come back within ten business days, and we're happy to sign an NDA before the first review call.
