IPU’s AtmoShield system dramatically reduces emissions on-site
As one of the county’s largest employers, James Hall wanted to enhance its role in the local community by reducing emissions years before regulatory limits came into force.
James Hall took the decision to meet the new limits long before that deadline came into effect. As one of the county’s largest employers, it takes pride in its position as a good corporate citizen.
The company had four goals:
- bring NOx emissions down from 1,300ppm to well below the limits set by legislation
- reduce the NOx emissions long before the legislation comes into effect,
- tackle emissions such as black smoke that may not be covered by legislation, and
- be ready for any future emissions legislation.
Like many examples of their era, James Hall’s generators were only fitted with silencers. Although adding exhaust abatement systems was a significant investment, replacing the generators would have been a more expensive and disruptive way to meet the limits set by legislation such as the Medium Combustion Plant Directive (MCPD) and its local implementation, the Environmental Permitting Regulations, 2018.
The company’s MTU 16V 4000G23 generators had been producing about 1,300ppm of NOx. With IPU’s abatement system, it could demonstrate its sense of responsibility and commitment to the community it serves.
IPU and Ingram Installations fitted each engine with an ‘SCRonF’ abatement system. This type of unit combines both SCR (Selective Catalytic Reduction) and DPF (Diesel Particulate Filter) substrates in one unit. The SCR element removes NOx. The DPF removes black smoke.
