Liquid Argon & CO2 Mobile Tank & Container Suppliers
Liquid argon and liquid CO2 mobile tanks and containers distribute these industrial gases from air separation units and CO2 recovery plants to customers in welding, food processing, beverage carbonation, specialty manufacturing, and semiconductor fabrication. Liquid argon is stored and transported at -186 °C in vacuum-insulated vessels similar to LOX and LIN equipment. Liquid CO2 is stored under pressure at -20 to -40 °C in single-wall insulated pressure vessels — technically not cryogenic but almost always grouped with cryogenic supply infrastructure.
The main formats in this category are road semi-trailers for bulk merchant supply, rigid road tankers for urban delivery, ISO tank containers for export and long-distance moves, and portable liquid cylinders for smaller users. Argon dominates in welding shielding gas, stainless steel argon-oxygen decarburization, and inerting. CO2 dominates in beverage carbonation, food freezing, greenhouse enrichment, and increasingly in CCUS supply chains.
This directory lists liquid argon and liquid CO2 mobile tank and container manufacturers worldwide. Stationary argon and CO2 storage is covered under the separate stationary cryogenic storage tanks category. Each supplier profile covers container formats, capacity ranges, design pressures (typically 15 to 22 bar for argon, 18 to 25 bar for CO2), holding times, code compliance under ASME, PED, ADR, and DOT, and certifications specific to food-grade CO2 supply where relevant.
Procurement teams evaluating suppliers typically compare delivered payload, holding time on typical delivery cycles, food-grade cleanliness certification for beverage-industry CO2, refrigeration units on CO2 trailers, road-legal tare weights, and integration with dispensing hardware. Filter by country, container format, gas served, or capacity.
Frequently asked questions
Is liquid CO2 actually cryogenic?
Not by strict definition. Liquid CO2 is typically stored at -20 to -40 °C under pressures of 15 to 22 bar. True cryogenic temperatures start below roughly -150 °C. However, CO2 equipment shares vacuum-insulated or heavily-insulated construction principles with cryogenic tanks and is normally sourced from the same suppliers.
What is the typical holding time for a liquid argon or CO2 tanker?
Liquid argon tankers with vacuum-perlite insulation achieve 3 to 6 days holding time before venting is needed. Liquid CO2 tankers rely on refrigeration units and insulation and can maintain product indefinitely with power, or 24 to 72 hours without power depending on ambient temperature.
Are food-grade CO2 tanks different from industrial CO2 tanks?
Yes. Food and beverage CO2 supply requires containers meeting EIGA Doc 70, ISBT beverage-grade specifications, or equivalent. Interior surfaces must be clean, gaskets and valve materials must be food-contact rated, and traceability documentation is required for each delivery.
Can argon and CO2 use the same transport container?
Rarely. Argon tanks are vacuum-insulated for cryogenic service; CO2 tanks are single-wall pressure vessels with foam insulation and refrigeration. The two are not interchangeable. Some suppliers do offer dual-service tanks for specialty applications, but these are unusual.
What certifications should suppliers demonstrate?
ASME U-stamp or PED CE for pressure vessels, ADR (Europe) or DOT (US) type approval for road transport, ISO 9001 quality management, and additionally EIGA Doc 70 or ISBT compliance for beverage-grade CO2. Argon-service containers do not require the LOX cleaning documentation applicable to oxygen service.
