Global supplier of NOx reagents used with
Selective Catalytic Reduction SCR technology.

ECOUREA offers a wide range of reagent solutions.

Reagents, when used in conjunction with a Selective Catalytic Reduction system (SNCR) to reduce nitrogen oxide (NOx) emissions, turn NOx into harmless nitrogen and water.

ECOUREA specialises in the production and supply of Marine Urea® for this purpose. We also produce and supply other reagents for the shipping, automotive and manufacturing industries.


ECOUREA offers a wide range of solutions to reduce your emissions and remain compliant in all areas.

AUS32 – (DEF / ARLA32)

Current transport legislation requires most transport operators to use (AUS32) throughout Europe, the United States of America, and internationally.

ECOUREA produces and supplies AUS32. It is a 32.5% urea solution that is widely used in the automotive industry with Specialist Catalytic Reduction (SCR) technology to reduce NOx emissions from diesel engine vehicles.

The AUS32 produced by ECOUREA can also be used with marine SCR units in the same way as Marine Urea®. Some vessels have calibrated their SCRs to run on AUS32 to ensure compliance with the ISO-22241 standards for AUS32.

Similarly, since the implementation of ISO-18611 for Marine Urea®, many vessels have also switched to AUS32 as well in order to achieve higher levels of NOx abatement.

ECOUREA is a one-stop supplier of AUS32. By working with partners, we have achieved cost-effective production and supply which keeps you compliant and sustainable.

Caustic Soda – 50% Sodium Hydroxide (NaOH)

The 50% Sodium Hydroxide Solution produced and supplied by ECOUREA is used with SOx abatement technology (mainly scrubber systems found in exhausts).

By spraying our caustic soda solution, mixed with fresh water, on to the exhaust gas, up to 97% of SOx emissions can be reduced, ensuring compliance with legislation.


AUS40 reagent, also known as Marine urea or DEF (Diesel Exhaust Fluid), is a non-toxic and colorless solution at 40% urea concentration, used in selective catalytic reduction (SCR) systems to reduce NOx (nitrogen oxides) emissions in diesel engines. The solution consists of purified water and urea, which react with NOx in the exhaust system of diesel engines to form harmless nitrogen gas and water vapor. AUS40 is injected into the exhaust stream of a diesel engine, where it vaporizes and mixes with the NOx, reacting with it in the SCR catalyst to produce the desired reduction in emissions. AUS40 reagent is widely used in the transportation industry, particularly in heavy-duty vehicles, to meet strict environmental regulations and improve air quality.

Providing Eco-Friendly Solutions.

ECOUREA has developed a very strong reputation for production and supply of Marine Urea, or Aqueous Urea Solution (AUS). It is a key product within our range of emission control products and services.

It is used as a reagent to reduce Nitrogen Oxide (No2) emissions from a variety of combustion processes, converting the gases in the emissions into water, nitrogen and carbon dioxide.

Marine Urea is the necessary reactant for the functionality of Specialist Catalytic Reduction (SCR) systems. It is a colourless, organic compound of carbon, nitrogen, oxygen and hydrogen (CO(NH2)2), and is a non-toxic, non-flammable and stable solution.

Our Product Quality.

ECOUREA customers can be sure of the quality of our product by means of our comprehensive manufacturing process using demineralised water, and the high calibre of our storage and transportation equipment.

ECOUREA manufactures all Urea solutions to Marine Urea ISO 22241 & ISO 18611 Standards.

Customers that receive Marine Urea are guaranteed optimum quality which will preserve the SCR system and provide consistently higher levels of NOx reduction. This ensures that international & local emission standards are always met.

We adhere to the worldwide standards for Marine Urea (AUS32 and AUS40).

Supply Mechanisms.

ECOUREA can supply Marine Urea to customers wherever they need it. Our global supply chain ensures that only top quality products are supplied and quality is maintained throughout storage and delivery.

We have a variety of different modes of transport at our disposal, depending on order quantity and region.
