Cryogenic Tanks
Stationary And Transportable Lin, Lox, Lar Tanks
KAF Cryogenics supplies stationary and transportable cryogenic tanks for LIN, LOX and LAR, built as double-walled, vacuum-insulated pressure vessels with an austenitic stainless steel inner vessel (typically grade 304L to EN 10028-7) and a carbon steel outer jacket, insulated with perlite in the vacuum space. Cold-stretched inner vessels are used on medium- and high-pressure models to optimize wall thickness while maintaining code compliance. Standard stationary capacities range up to 1,000 m³, with MAWP options from 3 to 37 bar in accordance with EN 13458 and the applicable requirements of the EU Pressure Equipment Directive (2014/68/EU, PED); AD 2000 Code and ASME Section VIII Division 1 are applied where the project or destination requires them. Each tank is fitted with a flow-diverter valve and dual pressure relief valves as standard, with provisions for level and pressure transmitters and remote telemetry where specified.
Tank orientation, insulation arrangement, connections and instrumentation are configured to the stored medium and site conditions. Vertical tanks are supplied on a four-leg support arrangement for ease of lifting and low-cost erection, while horizontal tanks are supplied with saddle supports for sites where headroom or footprint is constrained. Inner vessels intended for oxygen service are cleaned and prepared in accordance with EN 12300 to remove hydrocarbon residues before commissioning, and the normal evaporation rate (boil-off) is confirmed for the specific capacity and insulation package at the design stage.
Transportable equipment is available in standard capacities from 5 to 56 m³, engineered to EN 13530 and, where the unit will move by road, to ADR and TPED requirements. Vacuum-insulated semi-trailers and truck-mounted tanks are fitted with vacuum-jacketed piping and cryogenic valves to keep in-transit boil-off to a minimum, and 20 ft or 40 ft ISO container configurations can be provided for intermodal transport by road, rail or sea.
Frequently Asked Questions
Which configurations are available for LIN, LOX, LAR tanks?
The range includes vertical and horizontal stationary tanks as well as transportable equipment. The final configuration is selected according to the medium, required capacity, pressure, site arrangement and transport requirements. Each tank is a double-walled, vacuum-insulated pressure vessel with an austenitic stainless steel inner vessel and a carbon steel outer jacket, insulated with perlite or super insulation in the vacuum space. Cold-stretched inner vessels are used on medium- and high-pressure models.
Which design codes and standards apply?
Stationary tanks are designed to EN 13458 and, where required ASME Section VIII Division 1, in compliance with the EU Pressure Equipment Directive (2014/68/EU). Transportable equipment is designed to EN 13530, with ADR/TPED compliance applied for road transport.
How is the equipment prepared for oxygen service?
Inner vessels intended for LOX service are cleaned and prepared in accordance with EN 12300 to remove hydrocarbon residues prior to commissioning.
What valves and instrumentation are fitted as standard?
Each tank is fitted with a flow-diverter valve and dual pressure relief valves as standard, with provisions for level and pressure transmitters and remote telemetry where specified.
What capacities and pressure ratings are available?
Stationary storage capacities are available up to 1,000 m³ with MAWP options from 3 to 37 bar. Standard transportable capacities range from 5 to 56 m³. The exact combination is confirmed for the project.
How is the equipment optimized for the stored or transported medium?
The medium is defined at the specification stage and the tank configuration, pressure rating, insulation arrangement and connections are selected accordingly.
Are transport and ISO container options available?
Yes. 20 ft and 40 ft ISO container configurations can be provided for road, rail or sea transport, with vacuum-jacketed piping and cryogenic valves fitted to minimize in-transit boil-off. ADR/TPED compliance is applied to transport configurations where required.
What information should be provided for a quotation?
The main starting points are the medium, required capacity, MAWP or operating pressure, stationary or transportable requirement, preferred orientation, oxygen-service requirement where applicable, and destination or applicable project standard.
