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%.

A diesel particulate filter (DPF) is an aftertreatment device that acts as a physical barrier that removes particulate matter from the exhaust stream.
The UK implementation of the MCPD imposes different dust limits (either 10 or 20mg/Nm3) depending on the plant size and date of installation. Will the MCPD affect you? Find out here.
IPU’s Diesel Particulate Filters can reduce particulate matter by 95% and offer greater particulate trapping and storage capacity than other filters.
Diesel Particulate Filters will have the biggest focus in Clean Air Zones.
Clean Air Zones aim to address sources of pollution, including particulate matter, with the hope of reducing public exposure to them. London already has a Clean Air Zone, with plans to introduce an Ultra-Low Emissions Zone in April 2019. 5 cities are also required to introduce a Clean Air Zone by 2020; Birmingham, Derby, Nottingham, Leeds and Southampton.

As particulates accumulate in the filter, it needs to be regenerated (cleaned). There are two modes of regeneration, active and passive.
A heater can be used to regenerate the DPF (active regeneration). Other systems use a Diesel Oxidation Catalyst (DOC) to provide passive regeneration.
Some maintenance to the DPF is still required. Although soot can be regenerated, ash (another type of particulate matter) can’t. It can be removed with a specialist cleaning service provided by IPU (the frequency of this is dependent on engine duty cycle etc).

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%.
