Vacuum Insulation Systems Suppliers & Manufacturers
Vacuum insulation systems are the thermal barrier at the heart of nearly every cryogenic installation. By evacuating the annular space between two vessel walls to pressures below 10⁻⁴ mbar — usually combined with multi-layer insulation (MLI) — these systems suppress heat transfer by conduction, convection, and radiation, allowing liquefied gases to be stored and transported at temperatures as low as -269 °C.
Typical applications include industrial gas storage, LNG receiving terminals, liquid hydrogen fueling infrastructure, medical liquid oxygen distribution, laboratory helium handling, and semiconductor process gases. Whether you need vacuum-jacketed piping, cryogenic transfer lines, super-insulated storage vessels, or MLI blanketing for custom equipment, sourcing from a qualified supplier is essential to system reliability.
This directory lists vacuum insulation suppliers and manufacturers globally. Each supplier profile includes product range, pressure vessel code compliance (ASME BPVC Section VIII, PED 2014/68/EU, GB 150), insulation performance data such as heat leak in W/m² or boil-off in %/day, fabrication capacity, and geographic service coverage.
When evaluating vendors, procurement teams typically compare vacuum retention warranties, insulation performance data, custom fabrication capacity, regional code compliance, field re-evacuation capability, and track record with cryogens like liquid hydrogen or LNG. Use the filters to narrow by country, certification, product type, or industry served.
Frequently asked questions
What certifications should a vacuum insulation supplier hold?
At minimum, ISO 9001 for quality management and the pressure vessel code applicable to the destination market — ASME BPVC Section VIII in the US, PED 2014/68/EU in Europe, GB 150 in China. Suppliers working with hydrogen should also demonstrate EN 13530 or ISO 21009 compliance.
How long does vacuum insulation typically last?
Well-manufactured vacuum jacketed equipment maintains adequate vacuum for 15 to 30 years. Performance degrades gradually as residual outgassing raises internal pressure. Suppliers who offer re-evacuation service can extend service life indefinitely. Warranty terms of 5 to 10 years on vacuum retention are standard.
What is the difference between MLI and vacuum insulation?
Multi-layer insulation (MLI) is the reflective foil-and-spacer material installed inside the vacuum space. Vacuum alone eliminates convective and conductive heat transfer; MLI adds radiative heat rejection. Nearly all modern cryogenic systems use both together.
Which industries buy the most vacuum insulation systems?
Industrial gas (air separation, merchant gas distribution), LNG, liquid hydrogen mobility, healthcare (liquid oxygen, MRI helium), aerospace propellants, and scientific research including superconducting magnets and quantum computing.
Can suppliers manufacture custom vacuum insulated equipment?
Most major suppliers offer custom fabrication for tanks, piping runs, and specialty vessels. Lead times typically range from 8 to 20 weeks depending on complexity, dimensions, and certification requirements.
