For many year halter management has been actively involved in reducing the environmental impact of diesel engines and turbines. It was the first independent company to perform long term test with mobile Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR).
DPFs reduce harmful particulates by more than 95%.There are several technologies available for various applications. Apart from the fuel quality (sulphur content), exhaust gas temperature is critical in the choice of system. We will advise you on the best option for your application, be it mobile or stationary.
Electrically regenerating DPF,
ideally suited for Gensets
with low loads
SCR systems reduce Nitrogen Oxides (NOx) by more than 95%. Injecting urea into the exhaust gas stream will reduce NOx by the desired amount. Whilst the sulphur content of the fuel is less important, the temperature is critical. From the various technologies available, we will find the most suitable for your project. We will also assist you with the urea infrastructure.
Reactor of a De-NOx System
Oxi Cat will reduce Carbon Monoxide (CO) and Hydro Carbon (HC) by more than 80%. This technology is well proven and less demanding. Of course these three technologies can be used in combination to achieve a maximum reduction of harmful exhaust gases. From a variety of products and technology we will help you to find the best solution.
Biomass Derived Fuels can pose a serious problem for some of these systems. The exhaust gas quality can vary significantly depending on the bio mass used. Certain gases can poison the catalyst and make it ineffective. This has to be considered carefully when determining the system.
