UREA/ SCR dosing systems SCR dosing system for effective emissions control.
Hamburg: 38% of nitrogen oxide stems from maritime traffic
When ships such as the Queen Mary 2 sit with running diesel engines in the Hamburg port for a week, they then emit roughly as much nitrogen oxide as 1.5 million mid-range diesel cars. In total, this leads to the fact that approximately 38% of all nitrogen oxide in such cities is caused by ships in the port.
Environmental protection functions differently – that is: With SCR dosing systems from SCHERZINGER, exhaust systems can be retrofitted and reduce the amount of nitrogen oxides to a small proportion.

"Special circumstances made it necessary to bring forward the appointment by 8 to 10 weeks. With remarkable effort, the Scherzinger team tackled this and realized it in cooperation with us, despite the summer holidays!"
Effective exhaust gas purification through quick, precise injections of urea solutions
An effective contribution to protecting the environment and improving the quality of life in cities with large ports is made by cleaning exhaust gases and thus reducing nitrogen oxides. Urea solutions, which are injected into the diesel exhaust gases, are used for this purpose. These systems are called "SCR" (Selective Catalytic Reaction): nitrogen oxides are further treated with a reducing agent (e.g. urea/AdBlue®DEF) in an exhaust gas catalytic converter downstream of the engine. The reducing agent is split into ammonia and water. The ammonia then reacts with the nitrogen oxides in the exhaust gas and the nitrogen oxides are broken down into nitrogen and water.
The injection of the reducing agent must be constantly, quickly and precisely adjusted to the actual amount of exhaust gas produced - especially when there are load changes or changes in performance requirements. Reliability is also important: our gear pumps have an extremely long service life!
Precise and load-dependent dosing of all liquid reducing agents
Modular design from the simple pump to the complete intelligent dosing unit
Individual system configuration adapted to the respective application
