Diesel Particulate Filter for gensets (DPF)

IPU’s diesel particulate filters for gensets (otherwise known as DPFs) are aftertreatment devices that act as a physical barrier removing particulate matter from the exhaust stream.


Why are Diesel Particulate Filters for gensets important?

The UK implementation of the MCP Directive 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.

The visible reduction in particulate matter thanks to IPU’s DPF is clear to see. If you’d like to experience this reduction in action, register your interest to attend one of IPU’s Emissions Solutions demo days here.

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.

Regenerating your DPF

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).
