Custom-Geometry Vacuum Systems
What Are Custom-Geometry Vacuum Systems?
A custom-geometry vacuum system is a double-wall pressure containment assembly featuring non-standard shapes, configurations, or dimensional ratios designed to address specific installation constraints, process requirements, or operational needs. These vessels may incorporate toroidal (donut-shaped) forms, conical sections, non-circular cross-sections, compound curves, or integrated structural elements that enable installation in spaces inaccessible to conventional vessels. Despite their unconventional geometry, custom-geometry systems maintain vacuum insulation performance through careful engineering of the annular space configuration and support systems.
Why Choose Custom-Geometry Vacuum Systems?
Custom-Geometry Vacuum Systems offer several critical advantages:
- Space Optimization: Fit vacuum-insulated storage into non-rectangular spaces, building corners, or around existing equipment
- Process Integration: Match vessel geometry to specific reactor or process chamber configurations
- Structural Integration: Incorporate vacuum vessels into building structures, platforms, or equipment frames
- Unique Applications: Enable cryogenic systems in applications where standard vessels cannot physically fit
- Custom Aspect Ratios: Extreme height-to-diameter or length-to-width ratios for specific requirements

Frequently Asked Questions About Custom-Geometry Vacuum Systems
What types of custom geometries can Roben Mfg fabricate for vacuum systems?
We have fabricated toroidal (donut-shaped) vessels for accelerator applications, rectangular vacuum jacketed enclosures, conical systems, and vessels with irregular cross-sections. Our engineering team can assess feasibility and optimize designs for virtually any geometry that can maintain structural integrity under vacuum and pressure loads.
How is vacuum maintained in non-cylindrical custom-geometry vacuum systems?
Custom-geometry vessels require careful stress analysis to ensure outer jacket integrity under atmospheric pressure loading. The annular space follows the inner vessel contour with uniform spacing maintained by specialized support systems. Vacuum ports, getters, and MLI are positioned to function effectively regardless of vessel shape.
Are custom-geometry vacuum systems more expensive than standard designs?
Custom-geometry vessels typically involve higher engineering costs and more complex fabrication procedures than standard cylindrical or spherical designs. However, the ability to fit vacuum-insulated storage into previously unusable spaces often provides overall project savings by eliminating building modifications or equipment relocations.
