Anoxic Treatment for Cultural Heritage | Frequently Asked Questions

Transitioning to a Vacuum Nitrogen Anoxic System is a smart upgrade for any conservation lab. Here are quick answers to the most common questions from conservators.

Q1: Will the vacuum pressure tear fragile pages or old bindings?

No. Our chambers feature a patented 3-stage automatic pressure relief valve. Air evacuation and pressure equalization happen gradually, ensuring zero mechanical stress on delicate paper and ancient threads.

Q2: Do we need to constantly buy nitrogen gas cylinders?

No. Our industrial chambers include a built-in PSA nitrogen generator. It extracts and purifies nitrogen directly from ambient room air, producing an endless supply of 99.99% pure N2 on-site.

Q3: Is nitrogen treatment safe for all materials?

Yes. High-purity nitrogen is a 100% inert gas. It will never react with your artifacts. It is completely safe for paper, silk, leather, wood, and mixed-media objects without causing pigment fading or acidification.

Q4: How does it completely kill hidden insect eggs?

The system uses a controlled vacuum to extract air deep from within thick books. By dropping the oxygen level to <= 1%, it forces larvae and eggs to open their breathing pores, causing rapid dehydration and a 100% mortality rate.

Q5: Is the equipment complicated for our staff to operate?

Not at all. The cycle is fully automated via an intelligent PLC touchscreen. Just load the artifacts, select the program, and the system automatically manages the rest safely.
