Known Models (3)
Aalborg IGG 3000
5000 m3/h
· Inert Gas (flue gas)
Common Failures:
- • Scrubber packing deterioration
- • Non-return valve (deck) failure
- • Blower bearing wear
Service: Ensure O2 content <5% before admitting to cargo tanks; test P/V breakers.
Spares: Aalborg: Brennerdüsen-Satz, Photoauge und Dichtungen an Bord vorhalten. Lead time: 3-8 Wochen für Rohre.
Smit Gas Master IG
7500 m3/h
· Inert Gas (flue gas)
· Inert Gas Generation
Common Failures:
- • Scrubber tower fouling
- • Deck seal water level low
- • O2 analyser drift
- • SO2 breakthrough
Service: Flue gas type; maintain scrubber water flow and deck seal water level.
Spares: Smit: Brennerdüsen-Satz, Photoauge und Dichtungen an Bord vorhalten. Lead time: 3-8 Wochen für Rohre.
✔ Pros
- • High-quality inert gas production
- • Reliable and safe operation
- • Compliance with IMO regulations
- • Low maintenance requirements
- • Compact design for efficient installation
⚠ Cons
- • Scrubber tower fouling can occur if not properly maintained
- • Requires regular monitoring of deck seal water level
- • O2 analyser drift can affect system accuracy
- • SO2 breakthrough can be a concern if not properly addressed
- • Higher initial investment compared to some other models
