A Selective Catalytic Reduction system (SCR) reduces NOx emissions by combining exhaust gases with the reductant AdBlue (a type of urea) and passing it over a catalyst. IPU's SCR can reduce NOx emissions by 99.8%.

Legislation is cracking down on emissions from diesel gensets. The primary motivation for organisations to implement diesel emission controls is fundamental: because they have to.
With nationwide implementation of Clean Air Zones, non-road mobile machinery regulations and the new Medium Combustion Plant Directive (MCPD), it is essential that engines are compliant. IPU has emissions solutions to suit your application.

On-site power generation is dominated by diesel engines. They power the bulk of the world’s emergency generators, rental generators and energy market balancing reserves.
Their popularity is underpinned by unbeatable economy and reliability. If this popularity is to continue they need to address their greatest weaknesses: emissions.
Like any engine powered by a fossil fuel, diesel engines generate exhaust emissions that damage the environment. To safeguard their future, these emissions need to be brought down to a level that is comparable to less harmful fossil fuels such as natural gas.
The MCPD is EU legislation that became UK law in December 2017. The MCP Directive (Directive (EU) 2015/2193) covers diesel engines between 1 and 50 MWth capacity (described as medium-sized engines).
These diesel engines represent an important source of the emissions nitrogen oxides (NOx) and dust (particulate matter). The MCP Directive regulates the emissions of them with the sole aim of reducing these harmful substances that are known to be hazardous to human health as well as the environment.
The MCPD has been brought into force across the UK through 3 different regulations:
The NRMM is EU regulation to control emissions from engines not used on public roadways, including off-road vehicles such as construction and railway vehicles. Mobile generator sets are also included. Engines <19 kW and >560 kW fall under the non-road mobile machinery regulation.
Particular focus is being placed on the following emission types under the NRMM regulations: NOx, PM, Carbon Monoxide and Hydrocarbons (unburnt fuel).
Non-road mobile machinery will be unable to operate in London’s Ultra-Low emissions zone and other cities operating a clean air zone without being compliant to emissions regulations. Existing NRMM must now be retrofitted with emissions abatement technologies.
A Clean Air Zone is an area where specific action is being taken to improve air quality. Clean Air Zones aim to address sources of pollution, including nitrogen dioxide and particulate matter, with the hope of reducing public exposure to them.
London already has an Low Emission Zone in place, with plans to introduce an Ultra-Low Emissions Zone from April 2019. There are another 5 cities that are required to introduce a Clean Air Zone by 2020.
IPU has numerous diesel emission controls to suit different gensets, applications and emissions problems. These include:

A diesel particulate filter (DPF) is an aftertreatment device that acts as a physical barrier that removes particulate matter from the exhaust stream. IPU’s Diesel Particulate Filters can reduce particulate matter by 95%.

GTL Fuel is the acronym for Gas-To-Liquid. It describes the synthetic diesel alternative that turns natural gas into a liquid fuel suitable for use in unmodified diesel engines. It can reduce NOx emissions by up to 37% and particulate emissions by up to 38%.
