Representative Models

Static evaporation rates are reference values measured under specified test conditions. Actual performance depends on ambient temperature, operating pressure, filling level, piping configuration, and site conditions.

Model	Nominal Capacity	MAWP	Typical Static Evaporation Rate*	Dimensions (Ø × H)	Empty Weight
JLT-10/16	10 m³	1.6 MPa	≤0.40%/day	Approx. Ø2.2 × 6.0 m	Approx. 7.5 t
JLT-30/16	30 m³	1.6 MPa	≤0.30%/day	Approx. Ø3.0 × 8.5 m	Approx. 18 t
JLT-50/08	50 m³	0.8 MPa	≤0.25%/day	Approx. Ø3.4 × 10.5 m	Approx. 26 t

Construction

Inner vessel

Austenitic stainless steel selected for the design temperature, pressure, and stored medium.

Outer shell

Carbon steel or other suitable materials selected according to environmental conditions, structural requirements, and project specifications.

Piping

Stainless steel piping selected for cryogenic temperatures and thermal movement.

Vertical vs. Horizontal Cryogenic Tanks

Vertical tanks: Reduce ground space requirements but need sufficient overhead clearance for installation.

Horizontal tanks: Suit sites with height restrictions and use saddle supports on engineered foundations.

Selection depends on available installation space, transportation conditions, foundation design, and operating requirements.

Valves & Instrumentation

Standard Supply Configuration

Liquid filling and discharge connections
Gas-phase balance and pressure-building connections
Pressure relief and vacuum protection devices, as required by the design
Local pressure gauges and differential-pressure liquid level indicators

Optional Equipment

Dual relief valves with a changeover valve, where specified
4–20 mA pressure and level transmitters for remote monitoring
Economizer circuits and external pressure-building vaporizers
Oxygen-service cleaning for LOX applications

Control and Monitoring Options

Remote pressure and liquid level monitoring

Customized instrumentation according to customer requirements

Installation Requirements

Foundation

Design for the tank's filled operating weight, wind loads, and seismic conditions.

Piping

Provide independent pipe supports and accommodate thermal movement to limit nozzle loads.

Safety

Installation layout shall consider equipment clearance, vent routing, oxygen safety requirements (for LOX service), and applicable local regulations.

Engineering documents

Foundation loads, anchor bolt layouts, and installation instructions support site preparation.

Factory Testing

Material traceability: Mill test certificates are verified for pressure-retaining parts.

Weld inspection: Inner vessel welds undergo radiographic (RT) or ultrasonic (UT) testing in accordance with the design code.

Hydrostatic test: Pressure testing is performed according to the applicable design code, approved inspection plan, and project requirements.

Leak and vacuum test: Helium leak testing is performed on the inner vessel and piping, followed by final annular vacuum verification.

Final inspection: Instruments, safety devices, and nameplate data are checked, and test records are compiled into the data book.

FAQ

Q: What is the typical daily evaporation rate (NER)?

A: Static evaporation rates vary according to tank size, insulation performance, ambient conditions, operating pressure, and filling level. Reference values are provided in the technical datasheet.

Q: What is the service life and maintenance requirement?

A: The expected service life depends on design conditions, operating environment, maintenance practices, and periodic inspections.

Q: Can one tank store LIN, LOX, and LAr?

A: Yes. Tanks can be configured for LIN, LOX, or LAr service when material selection, cleanliness requirements, pressure rating, and safety accessories are confirmed for the intended medium.

Q: How do I size the tank?

A: Size the tank for 7–14 days of average consumption, plus 10–15% ullage and a delivery reserve.

Q: Why does LOX service require special cleaning?

A: Oil, grease, and organic residues can ignite in pure oxygen. Wetted parts must be degreased and verified to standards such as CGA G-4.1.

Q: What is the lead time for a standard tank?

A: Standard models such as JLT-30/16 take 60–90 days from drawing approval. Tanks of 100 m³ and above, or custom-code tanks, take 120–180 days.

Q: What happens if the vacuum degrades?

A: Frost on the outer shell and increased evaporation are common signs. The tank must be emptied and re-evacuated by qualified personnel.

Q: What does the warranty cover?

A: The warranty covers 12 months after commissioning or 18 months after shipment, whichever comes first. It covers manufacturing defects and vacuum loss, but excludes wear parts, improper operation, and non-compliant LOX cleaning.
