Using ISO 18661 quality manufacturing standard, AirNox specializing in production of Marine Urea which must be used in Emission Control Areas aiming to minimize airborne emissions from shipping vessels.
What is Marine Urea?
It is 40% urea solution used to reduce of NOx emissions from the combustion chamber of vessel diesel engines. What difference is between AdBlue® and Marine Urea? Both products give the same effect, only Marine Urea has higher urea concentration because of the bigger size of the vessel engine. What is Emission Control Areas? As of 2011 there were four existing ECAs: the Baltic Sea, the North Sea, the North American ECA, including most of US [and Canadian coast [and the US Caribbean ECA. Also other areas may be added via protocol defined in Annex VI. AUS 40 grade marine urea is a NOx reduction agent that has been specifically developed for use with SCR systems
in marine applications. Marine urea that meets the AUS 40 grade is manufactured to rigorous quality standards
specified by ISO 18611-1:2014, and will aid the longevity of the catalyst in the SCR system.
