Known Models (3)

Aalborg IGG 3000
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
Smit Gas Master IG

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
Typical Vessels: TankerLNG CarrierLPG Carrier
Certifications: IMO D-2USCG Type Approval
Decision Guide: Choose if you require a reliable and safe inert gas generation system for tanker operations, with a focus on compliance with IMO regulations. Avoid if you are looking for a low-initial-investment solution or have limited space for installation.
Use Cases: Typically deployed on tankers, LNG carriers, and LPG carriers, where inert gas generation is crucial for safe cargo handling and transport.
