Nitrogen Generation for Jewelry Manufacturing

Nitrogen Jewelry Manufacturing
Recommended Systems for Jewelry Manufacturing

Nitrogen Cylinder Filling

Nitrogen Membrane

Nitrogen PSA

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.
