Alfa Laval Membrane N2 Generator
20-200 Nm³/h N2 @ 95-99%
· Air → Nitrogen
· Membrane N2 Generator
medium: Air → Nitrogen
type: Membrane N2 Generator
Common Failures:
- • Membrane fiber degradation from oil/water
- • Pre-filter failure
- • Flow control valve malfunction
Service: Membrane N2 — lower purity than PSA but simpler. Oil-free air supply essential. Replace pre-filters regularly.
Spares: Alfa Laval: Spezialteile per Hersteller. Lead time: 4-8 Wochen. Gasdetektions-Sensoren an Bord.
Parker (Domnick Hunter) MAXIGAS Marine N2
50-500 Nm³/h N2
· Air → Nitrogen
· PSA Nitrogen Generator
medium: Air → Nitrogen
type: PSA Nitrogen Generator
Common Failures:
- • Carbon molecular sieve degradation
- • Switching valve failure
- • O2 analyzer drift
- • Air compressor fault
Service: PSA (Pressure Swing Adsorption). CMS replacement every 10-15 years. Monitor O2 purity continuously. Pre-filter maintenance critical.
