HJS Emission Technology

HJS Emission Technology

HJS Emission Technology was founded in 1976 with its headquarters based in Menden, Central Germany. HJS employs approximately 450 people who are engaged in the development, production and marketing of modular exhaust systems for reducing exhaust emissions on all road, rail, construction and marine applications.

In the UK our business is supported by our dedicated sales, project management and technical teams operating from our facility in Swindon, Wiltshire. From this facility, our engineering team provide nationwide installation and technical support.

HJS is the pioneers of Selective Catalytic Reduction Technology (SCRT®) which can be retrofitted to significantly reduce NOx emissions and virtually eliminates particulate matter. The HJS SCRT® system meets Euro VI standards and is both ULEZ, LEZ and CAZ compliant.

System performance has been certified at Millbrook Proving Ground and meets all of the requirements set out by the Energy Savings Trust’s ‘Clean Vehicle Retrofit Accreditation’ scheme (CVRAS). As a company, the thought that we can make the world a little cleaner with our products motivates us, to find out more contact us on 01344 566050 or email us
