MADE IN UK
REF.NO: FKM13897
The ABB AZ20/AZ25 is a remote mounted oxygen transmitter and analyzer designed for continuous O2 measurement in combustion and flue gas applications. As a remote unit, the transmitter electronics are separated from the measurement point, allowing installation away from high-temperature or hazardous zones — a practical advantage in boiler rooms, engine room exhaust systems, and combustion control installations onboard commercial and industrial vessels. Precise oxygen monitoring is fundamental to combustion efficiency, emissions management, and the safe operation of fired equipment at sea.
Key Features
✓ Remote mounted design separates transmitter electronics from the process measurement point for flexible, safe installation
✓ Wide AC supply input of 100–240V, 50/60Hz compatible with varied vessel and shore power systems
✓ Continuous oxygen measurement suited to combustion control, flue gas analysis, and related monitoring duties
✓ ABB AZ20/AZ25 platform — model AZ20/212112312116104; confirm compatibility with your existing system configuration before ordering
✓ Manufactured in the UK to ABB industrial instrumentation standards
Marine Applications
Boiler flue gas oxygen monitoring for combustion efficiency and fuel optimisation
Auxiliary and main engine exhaust gas analysis and emissions monitoring
Incinerator oxygen monitoring and combustion safety control
Waste heat recovery unit and exhaust gas boiler instrumentation
General industrial combustion process O2 monitoring, subject to system confirmation
Why Marine Engineers Choose ABB AZ20/AZ25
ABB’s AZ-series oxygen analyzers are well established in marine and industrial environments, valued for reliable continuous measurement, robust UK-manufactured construction, and broad compatibility with existing combustion control infrastructure — reducing integration time and complexity during replacement or retrofit projects.
Ideal For
Bulk carriers, tankers, container vessels, offshore support vessels, cruise ships, naval auxiliaries, and any vessel or installation operating fired equipment that requires continuous flue gas oxygen analysis.
Technical Support & Compliance
We offer complete solutions including remote troubleshooting, onboard technical support, testing and commissioning, repair, retrofit and upgrade services, and integration support for ABB AZ-series oxygen analyzer systems — all subject to confirmation. To confirm compatibility with your installation, please share nameplate photos, part numbers, system drawings, existing model and version details, vessel name and IMO number, and the full scope of your requirement.
