Nitrogen Generation for Jewelry Manufacturing

Jewelry Manufacturing

The furnaces used to melt gold for jewelry or connectors have a silent enemy – oxygen. O2 discolors the product and can dangerously weaken it. An onsite nitrogen generator can help remove oxygen and protect the integrity of the gold. Any metal over 600° F will oxidize in the presence of O2. The purity required for most metal applications is at most 99.99%; pressure 30-100 PSIG. Most are purge and fill applications, but all can be accommodated with larger or multiple nitrogen surge tanks instead of pressure-boosting compressors.
