Electronics Manufacturing
On-site PSA nitrogen generation for electronics and SMT processes where controlled nitrogen purity and reliable continuous supply are required.
Recommended Equipment
PSA Nitrogen Generator
CMS twin-tower continuous N₂. PLC automatic, skid-mounted. Electronics, food, chemical, laser cutting, heat treatment.
Vacuum Pump
Liquid ring vacuum for industrial vacuum, wet gas and degassing.
Key Selection Considerations
- Required nitrogen flow — The PSA nitrogen series covers 1–2000 Nm³/h. Consumption should be built up from all simultaneous users rather than taken from a single machine.
- Target nitrogen purity — The series spans 95%-99.999% N₂. Purity is set by the process, and because a higher purity reduces the achievable flow for the same generator size, demand and purity are confirmed together.
- Supply pressure — The series delivers up to 0.65 MPa (confirm selected model). The working pressure should be matched to the distribution network and the pressure loss across filters and pipework.
- Operating hours and load profile — Continuous and intermittent consumption call for different arrangements, and the load profile determines whether buffer capacity is required.
- Compressed-air supply and quality — PSA generation requires a clean, dry compressed-air feed. Available capacity and achievable dew point should be confirmed before sizing.
- Vacuum duties in the same process — Where vacuum is used for handling or degassing, define the vacuum level and gas load separately; the liquid-ring series reaches 33 mbar absolute at 0.45–8.33 m³/min.
Engineering Approach
Nitrogen demand is built up from the individual process users, and the highest purity requirement sets the generator size; because a purity margin reduces the achievable flow, the two are confirmed together. To raise a recommendation, send the required flow and purity, supply pressure, operating hours and load profile, compressed-air capacity and quality, and the site conditions.
Frequently Asked Questions
Why use PSA nitrogen generation for electronics?
On-site PSA nitrogen can provide a continuous nitrogen supply for processes such as soldering and reflow, with purity selected to match process requirements.
What determines PSA nitrogen generator size?
Required nitrogen flow and purity are primary sizing inputs, together with pressure, operating hours, compressed-air quality and the process load profile.
What nitrogen purity can be produced on site?
The PSA nitrogen series covers 95%-99.999% N₂. A higher purity reduces the achievable flow for the same generator size, so the process requirement should be fixed first.
What flow rate is available?
The series covers 1–2000 Nm³/h with outlet pressure of up to 0.65 MPa (confirm selected model). The duty point is confirmed once purity and total consumption are known.
Is a compressed-air supply required?
Yes. PSA nitrogen generation requires a clean, dry compressed-air feed, and its capacity and quality should be confirmed as part of sizing.
Can the same system also provide vacuum?
Nitrogen generation and vacuum duties are served by different equipment. Where both are needed, the vacuum level and gas load should be specified separately.
