Vacuum Insulated Reactors

Roben Mfg, Inc. fabricates vacuum insulated reactors for processes requiring minimal heat loss in cryogenic, low-temperature, or extended hold-time applications. Our vacuum insulation designs deliver superior thermal performance, maintaining process temperatures with minimal energy input for applications where conventional insulation cannot achieve required thermal efficiency.

What Are Vacuum Insulated Reactors?

Vacuum insulated reactors utilize an evacuated annular space between the process vessel and an outer shell to virtually eliminate conductive and convective heat transfer. This design provides thermal performance far exceeding conventional insulation materials, essential for cryogenic applications, extended temperature hold processes, and operations where heat loss significantly impacts product quality or energy costs.

Frequently Asked Questions

1. How effective is vacuum insulation compared to conventional materials?

Vacuum insulation provides thermal resistance equivalent to several feet of conventional insulation in just inches of annular space. Heat transfer is reduced by 90-95% compared to similar thickness of conventional insulation, making it essential for cryogenic and extended hold-time applications.

2. How is the vacuum maintained over time?

We design vacuum systems with getters and adsorbents that maintain vacuum levels over extended periods. Vacuum monitoring ports allow periodic verification. Some designs include provisions for re-evacuation if needed. Proper construction techniques ensure long-term vacuum integrity.

3. What temperature ranges suit vacuum insulated reactors?

Vacuum insulation is most advantageous at temperature extremes—cryogenic temperatures below -150°F where conventional insulation becomes impractical, and high temperatures where thin insulation profiles are desirable. We design for your specific temperature range and performance requirements.
