When environment matters
monitor your marine exhaust gases
Our ShipCEMS is designed to monitor your marine exhaust flue, ensuring that compliance with MARPOL Annex VI can be confirmed in ports, in international waters and emission control areas (ECA/SECA). Inspired by environmental concerns, ShipCEMS is designed to measure, analyse and report traces of SO2 and CO2 in wet marine exhaust flue. Monitoring of NOX, O2 or other gases are available as options.
As the flue gases are dirty, with a high content of soot, trace components can easily be lost before arriving at the analyser instrument. Our design solution is based on a heated sample treatment throughout, without needing to introduce chemicals. This assures that the true composition of the exhaust flue is measured.
ShipCEMS is designed for unmonitored, continuous operation. The user interface is simple and intuitive, with a limited number of operations necessary to use the system. The analysing technology is based on the use of non-dispersive infrared detectors (NDIR). This is a simple and robust measuring technology, being the industry standard when used in demanding applications.
ShipCEMS can monitor up to four processes simultaneously. One sample probe and one sample conditioning cabinet must be installed for each exhaust stack or combustion process to be monitored. Only one analyser cabinet is required, taking care of the necessary sample stream switching.
