eHeater The key to low exhaust emissions Electric heating element gets exhaust aftertreatment system fully functional in next to no time Future exhaust emissions standards, such as Euro VII, are expected to introduce significantly stricter requirements for pollutant emissions. Today’s emissions aftertreatment systems function excellently at exhaust-gas temperatures above 200°C. However, during operating periods…
SCRT + TMSCRT® Highly efficient aftertreatment system with active thermal management strategies Many commercial vehicle applications, mobile machines and stationary applications have load profiles that, owing to the low exhaust-gas temperatures, necessitate the use of active thermal management in order to guarantee full functional reliability of the exhaust aftertreatment system. This is important for regeneration…
Sintered Metal Filter with External RegenerationSMF-ER® It is vital that the correct diesel particulate filter system (DPF) is selected for short term use. These applications can be retrofitted with the HJS SMF® ER system in order to remove harmful soot particles from the exhaust. The SMF® ER system is characterised by its easy installation and…
SCRTSCRT® As early as the 1990s, soot particles could be eliminated from diesel exhaust gases down to the detection limit. HJS has specially developed the diesel particle filter from sintered metal (Sintered Metal Filter SMF®) for this and received the German Environmental Prize for it. For the reduction of the gaseous pollutants, in combination with…
SCR CatalystsSCR SCR catalyzers are used in order to decrease nitrogen dioxide emissions (NOx = NO + NO2) according to the so-called SCR process. SCR stands for Selective Catalytic Reduction and designates a process by which harmful nitrogen dioxides are converted selectively, i.e. targeted to a suitable catalyzer. In case of HJS, the development of…
Ceramic filters passively regeneratedDPF-CRT A passively regenerated ceramic filter for individual requirements. HJS filter systems are based on filter modules which are manufactured from ceramic materials. They are often used where no large ash quantities occur. These filter systems can generally replace the original acoustic damper in the area of retrofitting and can be adapted…
Sintered Metal Filter – Active RegenerationSMF-AR The SMF AR system is ideally suited toward applications with deviating application profiles and frequently low exhaust gas temperatures. These low temperature applications are more commonly found on construction sites, on mobile machines and static equipment. The SMF AR System (Sintered Metal Filter with Active Regeneration) regenerates autonomously regardless…
Sintered Metal Filter Passive RegeneratedSMF-CRT The modular SMF® technology was developed specially for applications in the medium to high range of performance. These filter systems can generally replace the original acoustic damper in the area of retrofitting and can be adapted individually to the machines and stationary applications. Passively regenerated particle filter for individual requirements…
