FAQ

What factors determine the size and capacity requirements for an industrial nitrogen machine

The sizing of an industrial nitrogen machine depends on several critical factors including peak nitrogen demand, purity requirements, operating pressure needs, and duty cycle patterns. Peak demand calculations should include all simultaneous uses plus a safety margin typically ranging from 20-30%. Purity requirements vary significantly by application, from 95% for some blanketing applications to 99.999% for electronics manufacturing. Operating pressure requirements and the need for backup systems during maintenance also influence sizing decisions.

How does the purity level of nitrogen affect different industrial applications

Nitrogen purity requirements vary dramatically across industrial applications, with each use case demanding specific purity levels for optimal performance. Food packaging typically requires 99.5-99.9% purity to prevent oxidation and extend shelf life, while electronics manufacturing demands 99.999% or higher to prevent contamination. Metal heat treatment applications may operate effectively with 95-98% purity for basic inerting, whereas pharmaceutical manufacturing requires ultra-high purity to meet regulatory standards and prevent product degradation.
