Exhaust Gas Catalyser
If a replacement of the exhaust gas catalyser is due on a vehicle, the customer is spoiled for choice: Does he opt for the expensive original product of the vehicle manufacturer, or does he latch onto a replacement product from a pile of substitutes, supposedly equivalent and often from unknown manufacturers? Many of the replacement catalyzers offered on the market are processed so badly that they are useless after a short time. Furthermore, non-serious providers of catalyzers frequently save on expensive precious metals during processing, whose catalytic effect is a decisive factor in the function of exhaust gas cleaning.
For this reason, the introduction of the “Blue Angel” for catalyzers was initiated in 2013. The “Blue Angel” is the oldest and most common environmental sign for products and services worldwide. For more than 35 years, it has contributed to enlarging and strengthening the sustainability concept in the economy. In the area of exhaust gas treatment, the environmental sign should contribute to a permanent and efficient adherence to emission limit values. A process was developed for this purpose, where the aging of catalyzers is simulated and the physical load-carrying capacity is tested intensively. This test ensures that the replacement catalyzer is in fact comparable with the series system, and also meets all legal requirements.
This means that “The Blue Angel” is the distinguishing feature for high-quality catalyzers.
Catalyzers from HJS
HJS Emission Technology, as a premium manufacturer of environmental protection technologies, stands fully behind the environmental angle for catalyzers.
Since the announcement of plans for the introduction of the “The Blue Angel” environmental sign, we have further developed our catalyzers subject to new prerequisites on quality, service life, and emission characteristics. We call this new catalyst Generation HJS.
Defective catalyzers cause more harmful exhaust gases than are allowed and have a short service life. This not only pollutes the environment and impairs health, but also ends up being expensive for the motorist. Bluemission catalyzers from HJS are the first choice for the environmentally aware and cost-conscious motorist, with a guarantee period of 4 years or 120,000 kilometers.
As the first manufacturer of catalyzers, HJS was honoured with the environmental sign “The Blue Angel”. With that, the starting gun was fired for the consistent market launch of catalyzers with environmental impact in mind.
Advantages of the HJS Bluemission® catalyzers
1. Unmatched Environmental Compliance
“Blue Angel” certification (world’s oldest eco-label) guarantees strict adherence to emission limits, surpassing legal requirements.
Rigorous testing simulates aging and stress to ensure long-term efficiency in reducing CO, NOx, and HC emissions.
2. Premium Quality & Durability
Generation HJS catalyzers are engineered for extended service life, avoiding premature failure common in cheap replacements.
High precious metal content (platinum, palladium, rhodium) ensures optimal catalytic conversion vs. competitors who cut costs.
3. Cost-Effective for Vehicle Owners
4-year/120,000 km warranty (unmatched in aftermarket) reduces long-term ownership costs vs. frequent replacements of inferior catalyzers.
Prevents failed emissions tests and fines by maintaining compliance over time.
4. Trusted OEM Alternative
Comparable to original manufacturer catalyzers in performance but more affordable.
No compromise on materials or construction—unlike “unknown” aftermarket brands with poor durability.
5. Health & Sustainability Benefits
Reduces harmful pollutants (e.g., NOx, particulate matter) that impact air quality and public health.
Supports circular economy principles with durable designs that minimize waste.
6. Industry-Leading Credibility
First catalyzer manufacturer awarded the “Blue Angel”, setting the benchmark for eco-friendly exhaust tech.
Transparent testing and certification give customers confidence in performance claims.
