What is it?
The G3621 is an advanced oxygen analyzer system specifically designed to measure oxygen levels in the exhaust gases of ships and industrial plants. This system plays a key role in optimizing combustion processes, making fuel usage more efficient and reducing harmful emissions. By continuously monitoring how much oxygen is present in the exhaust gas, the G3621 helps operators run their installations in a more environmentally friendly and safer way.

How does it work?
The system takes a small sample of the exhaust gas from a dedicated point in the ship’s funnel or exhaust system. Using an electrochemical sensor, the analyzer accurately measures the oxygen concentration in this gas sample. The G3621 is built to operate reliably and continuously, even under the tough conditions found on board ships, where temperature and humidity can vary. Thanks to its built-in self-diagnosis and self-calibration features, the system always provides precise readings with minimal maintenance required.

What problems does it solve?
Accurately measuring oxygen in exhaust gases is crucial to comply with international environmental regulations such as IMO MARPOL Annex VI. Knowing the exact oxygen levels allows operators to adjust the combustion process, reducing the release of harmful substances like nitrogen oxides and carbon monoxide. This not only helps lower environmental pollution but also improves fuel efficiency. Additionally, the system prevents dangerous situations that may arise from incomplete combustion or overheating. Thanks to its reliable technology and low-maintenance design, ships and industrial installations can operate safely, cleanly, and economically.
