Liquid Oxygen & Nitrogen Mobile Tank & Container Suppliers
Liquid oxygen (LOX) and liquid nitrogen (LIN) mobile tanks and containers form the transport backbone of the industrial gas supply chain. Delivered from air separation units to customer sites and merchant gas depots, this equipment moves the highest-volume cryogenic products in the industry — LOX at -183 °C and LIN at -196 °C — in vacuum-insulated vessels ranging from portable 240-liter liquid cylinders up to 60,000-liter semi-trailers.
The main formats in this category are road semi-trailers for bulk merchant supply, rigid road tankers for smaller deliveries and urban routes, ISO tank containers for intermodal transport and export, and portable liquid cylinders for hospital, laboratory, and small industrial use. Applications span steelmaking, medical oxygen supply, food freezing, chemical inerting, semiconductor manufacturing, and metal cutting.
This directory lists LOX and LIN mobile tank and container manufacturers globally. Stationary LOX and LIN storage is covered under the separate stationary cryogenic storage tanks category. Each supplier profile covers container formats, capacity ranges, design pressures typically 12 to 22 bar, holding times, code compliance under ASME BPVC Section VIII, PED, ADR, DOT 4L, cleanliness standards for LOX service per CGA G-4.1 or ASTM G93, and pump-off versus pressure transfer configurations.
Buyers comparing suppliers typically weigh delivered payload after tare, holding time and vent losses on typical routes, LOX-cleanliness certification, delivery hardware including hoses and couplings, road-legal weights in the destination market, and lifecycle costs including scheduled inspections at 5-year and 10-year intervals per code. Filter by country, container format, or capacity.
Frequently asked questions
What is the typical capacity of a LOX or LIN road tanker?
European semi-trailers commonly hold 20,000 to 26,000 kg of LOX net payload (about 17 to 23 m³ liquid). US road tankers deliver similar volumes depending on state weight limits. Rigid trucks for urban delivery typically carry 6,000 to 12,000 kg. Portable liquid cylinders hold 180 to 270 kg.
Why do LOX containers need special cleaning?
Liquid oxygen supports rapid combustion of hydrocarbons and organic residues. Containers must be oxygen-cleaned to CGA G-4.1, ASTM G93 Level C or better, EIGA Doc 33, or equivalent — removing oils, particulates, and volatile organics below specified limits before being placed in oxygen service.
How is boil-off managed during transport?
Mobile tanks are equipped with pressure-building coils and vent circuits sized for the expected route and holding time. Vent losses are typically 0.5 to 2.0 % per day depending on tank size and ambient conditions. Vent gas is released through relief valves; product loss is a normal operating expense.
Can the same container be used for LOX and LIN service?
In principle yes, if the container is cleaned for oxygen service and materials are LOX-compatible. In practice most fleets segregate LOX from other cryogens to avoid recleaning costs and cross-contamination. LOX-service containers can generally handle LIN, LAR, or LNG without additional cleaning.
What certifications should a LOX or LIN tank supplier hold?
ISO 9001, ASME U-stamp or PED CE certification for pressure vessels, ADR type approval for road transport in Europe, DOT 4L specification in the US, and demonstrated compliance with EIGA Doc 06 or CGA 341 for cryogenic transport equipment. LOX-cleanliness documentation per CGA G-4.1 must be provided with each unit.
