GAA610-M ADVANCED EMISSION GAS MONITORING SYSTEM | OI/GAA610-M-EN REV. B
2 Design and function
Measuring principle
The GAA610-M is based on ABB's proven NDIR (Non-Dispersive
Infrared) measurement technology.
The analyzer module Uras26 allows for reliable measuring and
monitoring of the limit values for SO
ratio as specified by the IMO (International Maritime
Organization), and it can be employed for continuous monitoring
of CO if required.
Device description
The GAA610-M is a multi-component analyzer system
continuously providing real-time data of relevant pollutants like
SO
/CO
ratio.

It proves compliance of vessels to low emission limits of
emission control areas (ECA zones) and global limits.
The measurement can be used to control the exhaust gas
cleaning system on board, so called scrubber as well.
The GAA610-M is proven for use on board by all major
classification societies and complies with Marpol Annex IV
requirements and NO
Technical Code2008.

Reducing maintenance hassles during ship operation has been
the guiding principle for development. An increased uptime is
provided with the GAA610-M by its robust and simple design as
well as its innovative digital features allowing for tailored
services according your needs.
The GAA610-M analyzer system extracts the sample gas from the
exhaust gas stream.
The gas analyzer cannot process the sample without further
treatment as e.g. an excessive dust content, temperature and
dew point, excessive or insufficient pressure and interference
components in the sample gas can affect the operating ability of
the gas analyzer and distort the measurement result.

Therefore, additional devices, such as the sampling probe, the
sample gas line, the sample gas cooler, pumps and filters ensure
that the sample gas entry conditions of the connected gas
analyzer are met, and a proper measurement result is obtained
regardless of the process and the local conditions.
The sample handling system is specific for the applied
measuring principle.
The GAA610-M analyzer system is a complete turn-key solution
with the following components:
•
Probe and filter unit for proper gas sampling
•
Heated sample gas line for feeding the sample to the gas
analyzer
•
Sample conditioning components like sample gas cooler,
filters and pump to ensure the gas conditions for reliable
measurement results
•
AO2020-Uras26 gas analyzer (Advance Optima – AO2000
series) for measuring SO
The sample conditioning components and the gas analyzer are
integrated into the analyzer cabinet of the analyzer system.
Available options are:
•
Air conditioning unit for operation at ambient
temperature 5 to 55 °C (41 to 131 °F). Higher ambient
temperature during operation on request.
•
Dual sampling for simultaneous measurement at two
different sampling locations (on request)
