VacuEco VPU Is Tested On Sites And Passes Real-World Engineering Conditions

Any material or process used in a large LNG storage tank project must meet real-world engineering conditions.

Construction sites are large, schedules are long, workflows are complex, and quality control is demanding. A solution that performs well only in the lab but cannot be installed efficiently and consistently creates little practical value.

The VPU developed by VacuEco, a Super Tech brand, is a metal-envelope VIP + PU composite module. Its value lies not only in high insulation performance, but also in a modular design suited to engineering use.

What Is VPU?

VPU (Metal-Envelope VIP + PU Composite Module), also described as a "VIP + PIR/PU Composite Insulation Panel," combines a high-barrier 304 stainless steel VIP with PU. Developed by VacuEco for large cryogenic storage tanks, it provides extremely low thermal conductivity—about 1.2mW/m·K after lamination—together with the advantages of modular installation.

Flexible Dimensions for Different Tank Structures

VacuEco VPU is available in different thicknesses, widths, and lengths to suit different applications:

VPU is not limited to a single standard size. It can be engineered around the tank structure.

For customers, the benefits are direct:

• Easier integration with complex structures;

• Easier staggered-joint installation;

• Simpler on-site installation management;

• Better suited to standardized project execution.

Two Installation Methods for Full-Containment and Membrane Tanks

In full-containment tanks:

VacuEco VPU can be bonded to the inner face of the outer concrete wall and combined with perlite filling to improve insulation. Installation is simple: the modules are bonded in place without major structural changes.

In membrane tanks:

VPU can be pre-laminated into PU or PIR insulation modules, integrating high-performance insulation during factory production.

Both methods have one advantage:

They turn high-performance insulation into modular products that are easier to install and manage. Compared with extensive on-site processing, this improves installation efficiency and quality consistency.

Staggered Joints Reduce Thermal Bridging

Thermal bridge control is critical in VIP applications.

What Is a Thermal Bridge?

A thermal bridge is a more conductive part of the insulation system through which heat flows more readily, reducing overall performance. In VPU applications, module joints are potential thermal bridges.

VacuEco VPU uses a metal barrier layer only about 0.1mm thick. Staggered-joint installation extends the heat-flow path and greatly reduces thermal bridging, bringing system performance closer to the intrinsic performance of the insulation material.

VacuEco VPU is Easy to Install

Large energy projects are naturally cautious about new materials. Customers need to know whether performance is proven, installation is practical, quality is controllable, and risk can be managed.

Through modular design, VacuEco makes high-performance insulation easier to engineer and deploy.

High performance should not mean high complexity.

VacuEco VPU turns LNG tank insulation upgrades from a technical possibility into an engineering-ready solution.
