Partnerships

Four partnerships are on record, tiered core.

• EIWilliams IndustriescoreStrategic or Co-development Partner · 15 August 2025IMSeco partnered with EIWilliams Industries to implement Airless IMSeco SCR Systems on 1625kVa Cummins QSK60G engines at a Texas, USA site. EIWilliams Industries serves as the implementation partner in this US market entry for IMSeco SCR technology, with the SCR systems deployed on large Cummins gas engines for power generation applications.
• Energy Saving TrustcoreTechnology or Integration · 13 September 2021The IMS-eco SCRT Device (21-10722) was tested and accredited by the Energy Saving Trust to meet Stage V standards for mobile generators. This accreditation enables the device to be listed as an approved 'NRMM-RAS' Emissions Abatement Device under the London NRMM LEZ scheme, a prerequisite for operating in regulated zones.
• HS2 (High Speed 2)coreStrategic or Co-development Partner · 13 September 2021HS2 requires all off-road machinery used along the 345-mile route to meet EU Stage IV (and EU Stage V for Generators) emissions standards. IMSeco SCRT systems have been deployed to help contractors meet these requirements. Since January 2020, all NRMM machinery on HS2 sites must comply with Stage IV/V standards.
• London NRMM LEZ (Mayor of London / London Boroughs)coreStrategic or Co-development Partner · 13 September 2021London's NRMM Low Emission Zone uses London Boroughs Planning Powers to control emissions for machinery with power ratings between 37-560kW. IMSeco SCRT devices are accredited by Energy Saving Trust as approved NRMM-RAS emissions abatement devices for compliance. Stage V standards apply across all of London from January 2030.

Expansion highlights6 records

Direct peers

• Bosal: Belgian-headquartered global manufacturer of exhaust systems, silencers, and catalytic converters serving automotive and industrial markets. Closely comparable to IMS's silencer and emissions control product lines across power generation, marine, and industrial applications.
• Eberspächer: German family-owned Tier-1 supplier of exhaust technology, catalytic converters, and SCR systems for automotive, commercial vehicle, and industrial applications. Directly competes with IMSeco in SCR and catalytic converter technology for engine emissions compliance.
• Donaldson Company: US-based global manufacturer of filtration systems including industrial air filtration, exhaust systems, and emissions control. Comparable to IMS in serving industrial, power generation, and OEM customers with air quality and emissions solutions.
• CECO Environmental: US-listed provider of engineered solutions for industrial air quality, including industrial silencers, filtration, and emissions control systems. Highly comparable product portfolio to IMS's acoustic solutions and serves similar industrial end markets.

Broad incumbents

• Faurelia (FORVIA): Global automotive Tier-1 with a major emissions control business (formerly Faurelia Emissions Control). A much larger incumbent serving automotive OEMs; comparable technology overlap in catalytic systems and exhaust aftertreatment, but at substantially greater scale.
• Tenneco (DRiV): Global powertrain and emissions control supplier (DRiV aftermarket business), with significant presence in industrial and commercial vehicle silencers and aftertreatment. Comparable product overlap with IMS's silencer and emissions portfolio but at a vastly larger scale.
• Munters: Swedish global leader in energy-efficient air treatment and climate solutions, including industrial air handling and emissions control. Comparable in serving industrial customers with engineered air quality and acoustic solutions, but with a broader HVAC/data centre focus.

Others

• Atlas Copco: Swedish industrial group providing compressors, vacuum solutions, and power generation equipment. Adjacent rather than directly competing — many of Atlas Copco's power generation customers are also IMS end customers requiring silencers and aftertreatment.
• Cummins: US-listed global manufacturer of diesel and gas engines, including the QSK60G series used in IMS's Texas SCR project. Key OEM customer of IMS — Cummins engines are a major install base for IMSeco SCR and silencer retrofit programmes.

Regional players

• Generac Power Systems: US-domiciled global leader in backup power generators, predominantly serving North American data centre and commercial markets. Highly relevant as a downstream customer and end-market driver for IMS's data centre SCR and acoustic enclosure business.
