Dubious claims are a danger! We see it time and again in tenders for large projects: competitors brazenly claim to have “technically equivalent products” at half the price. But if you take a closer look, you will immediately see that this is nothing more than window dressing. No test bench, no CFD analysis, no patents, no scientific documentation. Just empty words, supported by flimsy papers or management letters. Such an approach is not serious. It is dangerous. And it is disrespectful to customers who depend on quality and safety.
Cheap tricks instead of real technology
What these providers do is simple: they claim. Nothing more. No research, no development, no investment in measurement technology. Instead of facts, there are only colorful brochures with no technical substance. Instead of test reports, just assertions. The problem: many customers fall for this scam because the price sounds tempting. But the truth is: anyone who uses such products is risking the safety of people, machines and the environment.
X-CYCLONE technology in comparison: facts instead of claims
We do the opposite. We don’t just talk, we prove it. X-CYCLONE technology is the result of decades of research and millions in investment. We have state-of-the-art CFD analyses, our own test benches, scientific partners such as TÜV and Fraunhofer, doubly patented developments and hard measurement data.

- Up to 99.999 % degree of separation – scientifically proven.
- No bypass openings, 0 m³/h short-circuit flows – because we were the first to completely eliminate the bypass problem.
- Flameproof in accordance with DIN 18869-5 and DIN EN 16282 – type A because tested and documented for everyone to see.
- Lifetime guarantee, maintenance-free, self-cleaning
- Twice patented X-profile geometry – developed with CFD simulations
- Tested and approved with TÜV and Fraunhofer Institute
That is the difference between research and assertion.

Why cheap copies are risky
Those who rely on “equivalent” cheap products are not saving money, they are taking risks:
- Safety risks due to lack of flame transmission test
- Poorer separation, higher load on people, machines and exhaust air ducts
- No transparent documentation, no evidence, no guarantee
In the worst case, the use of such products leads to fires, higher operating costs and massive consequential damage.
Conclusion: Trust needs evidence
A comparison of X-CYCLONE technology clearly shows that it is not enough to simply make claims – we provide real facts, scientific evidence and decades of experience. If you want quality, safety and sustainability, choose proven technology and not cheap copies without substance.

Also a big topic on LinkedIn
A LinkedIn post by Sven Rentschler on the same topic generated a lot of interest, so here is the course of the conversation and the LinkedIn post by Sven Rentschler for your information:
Real technologies instead of stupid bullshit blah blah blah! Have you ever thought about what the definition of technology actually is?
In my Technology Management course, I was taught the following:
“𝑻𝒆𝒄𝒉𝒏𝒐𝒍𝒐𝒈𝒊𝒆 𝒊𝒔𝒕 𝒅𝒊𝒆 𝒔𝒚𝒔𝒕𝒆𝒎𝒂𝒕𝒊𝒔𝒄𝒉𝒆 𝑨𝒏𝒘𝒆𝒏𝒅𝒖𝒏𝒈 𝒗𝒐𝒏 𝐧𝐞𝐮𝐞𝐦 𝒘𝒊𝒔𝒔𝒆𝒏𝒔𝒄𝒉𝒂𝒇𝒕𝒍𝒊𝒄𝒉𝒆𝒎 𝑾𝒊𝒔𝒔𝒆𝒏 𝒂𝒖𝒇 𝑷𝒓𝒐𝒅𝒖𝒌𝒕𝒆 𝒅𝒆𝒔 𝒕𝐚𝐞𝒈𝒍𝒊𝒄𝒉𝒆𝒏 𝑮𝒆𝒃𝒓𝒂𝒖𝒄𝒉𝒔 𝒖𝒏𝒅 𝒂𝒖𝒇 𝒑𝒓𝒂𝒌𝒕𝒊𝒔𝒄𝒉𝒆 𝑷𝒓𝒐𝒃𝒍𝒆𝒎𝒆.”
Why am I writing this down here? Quite simply because it’s really getting out of hand how dubious and unsubstantiated market competitors are in this area. Inflationary how many also have new technologies! Inflationary how many seem to have similar and equivalent technologies! This begs the question:
“𝑾𝒂𝒔 𝒔𝒊𝒏𝒅 𝑬𝒖𝒓𝒆 𝒘𝒊𝒔𝒔𝒆𝒏𝒔𝒄𝒉𝒂𝒇𝒕𝒍𝒊𝒄𝒉𝒆 𝑴𝒆𝒕𝒉𝒐𝒅𝒆𝒏, 𝑽𝒆𝒓𝒇𝒂𝒉𝒓𝒆𝒏 𝒖𝒏𝒅 𝑾𝒆𝒓𝒌𝒛𝒆𝒖𝒈𝒆, 𝒎𝒊𝒕 𝒅𝒆𝒏𝒆𝒏 𝒏𝒆𝒖𝒆𝒔 𝑾𝒊𝒔𝒔𝒆𝒏 𝒊𝒏 𝒌𝒐𝒏𝒌𝒓𝒆𝒕𝒆 𝑳𝐨𝐞𝒔𝒖𝒏𝒈𝒆𝒏 𝒖𝒏𝒅 𝑷𝒓𝒐𝒅𝒖𝒌𝒕𝒆 𝒖𝒎𝒈𝒆𝒔𝒆𝒕𝒛𝒕 𝒘𝒖𝒓𝒅𝒆?”
Why am I asking this? You wouldn’t believe how many competitors in the market, such as Holger Reul, Alexander Rojahn, Sascha Kess, Vitali Lai and our planning partners, will soon be telling our sales team on a weekly basis that they can offer technologically and technically equivalent products at half the price. Without any proof, without any research & development, without any measurement technology, just very large, overblown bullshit bubbles, any questionable confirmations and little long-term observation…!!!!
P.S. Dear market companions of ventilation technology: A thermal image is not a CFD and has nothing to do with numerical flow analysis… Just to give you a small example of the nonsense that is spread every day!
