[Latest Case] We have added the latest examples of measures against red rust and red water!

  • CATALOG

Recently, there has been a sharp increase in consultations regarding "red rust and red water" in cooling equipment such as cooling towers, chillers, piping, and heat exchangers. Common concerns among the companies seeking advice include: - Decreased cooling efficiency compared to before (in some cases, this is detected as an anomaly) - Red rust not being removed even with the use of chemicals - Water becoming cloudy and red again shortly after being replaced - Frequent cleaning and maintenance, leading to excessive effort and labor These cases often involve companies that have left the issue unresolved for years, unsure of what to do since chemical treatments have not improved the situation. Red rust tends to occur in inconspicuous areas within the piping, which often leads to delaying countermeasures. However, during this time, the piping continues to deteriorate due to the red rust. By the time it is noticed, there may be holes causing water leaks, or the piping itself could break, leading to emergency repairs and the urgent shutdown of production lines. Our company has resolved over 100 cases of red rust and red water issues over the past 20 years. We have added our latest case studies to our "Case Study Collection." The severely discolored red water has dramatically improved. Please take a look.

【ACR】Effective for rust removal and rust prevention on chillers!

  • CATALOG

<Removes and suppresses rust from chillers, piping, and heat exchangers> The 'Aqua Crystal Ring (ACR)' is a scale removal device that demonstrates tremendous effectiveness in removing scale from cooling towers, without the need for chemicals or power supply. ACR not only removes scale but also has a remarkable effect on rust. In most cases, a large amount of rust accumulates in chillers (cooling water circulation devices) and piping. As a result, it is common for the water inside the chiller to turn bright red (red water). By using ACR, red rust can be converted to black rust, and the murky red cooling water can be improved to a clear state. This is achieved without any use of chemicals and does not require a power supply. ◆◆ We have received a lot of feedback ◆◆ Recently, in addition to scale removal from cooling towers, we have received many inquiries regarding rust in chillers and piping. In response, we have compiled materials on the effects of ACR on rust. Companies struggling with rust, please take a look.

Key PartnersI chose a device that no one believes in as my last job in life. Nice to meet you. My name is Yasuhiro Wada from Archive Co., Ltd., an Aqua Crystal Ring sales agency. I am currently making proposals to free factories and facilities with cooling towers and chillers from the problems of 'rust' and 'scale' through a device called the 'Aqua Crystal Ring' (abbreviated as ACR), and for about 20 years, over 100 companies have adopted it. However, I originally worked in the printing industry for 35 years. I was in a world completely unrelated to cooling towers. But eventually, the printing industry fell into recession, and I thought, 'I really need to start something else.' At that time, a trusted friend said to me, 'Wada-san, there’s an interesting device called ACR. It cleans water.' What he showed me was that small, white, round device that looked like a little 'ring.' I thought, 'A toy?! There’s no way something like this can change water.' But he spoke about it so enthusiastically that I thought, 'Well, let’s go take a look.' I went to the site since I had plenty of time with no printing orders at that time (laughs). What I saw there was the water in the chiller tank, murky red with rust. I thought to myself, 'This must be a stain that even strong chemicals can’t remove...' But he smiled and said, 'It’s okay. It will gradually get cleaner, so let’s test it.' I was surprised and worried, thinking, 'Is this something you sell by lying??' (laughs) But I was curious about the test results, so I went to that site multiple times. Two months, three months, six months. The water really did gradually become clearer. And a year later, something unbelievable happened. The 'scale' that had troubled us, which couldn’t be removed even with special chemicals, was completely gone, and that murky red water was now transparent!! Honestly, I don’t understand the reasoning! It was like a magical test result. For someone knowledgeable in chemistry, it might be even harder to accept. But having seen that change, I had no choice but to believe. There was not a single lie in what happened on-site. Moreover, it wasn’t about forcibly cleaning with strong chemicals; it was about safely cleaning over time with this ACR, and I fell in love with it. Plus, there’s no need for construction or electrical work to use ACR! The ease of just dropping it into the tank was also a key point. From there, I wanted to share this ACR with more people. Fortunately, there were many factories within my reach that could benefit from ACR! Although I jumped in to let them know about ACR, initially, I was completely ignored everywhere. I couldn’t even get anyone to listen to me. But I thought it would be a waste of time to get discouraged by that, so I decided to take a different approach and started a website and began writing a blog. I’m not good with computers, but I continued to post little by little, and around the time I wrote 100 posts, the search ranking for 'cooling tower scale removal' began to rise, and by the time I exceeded 300 posts, inquiries started to come in gradually. And from the companies that actually adopted it, I received happy feedback like, 'It didn’t work even with such strong chemicals, but ACR really changed things,' 'It’s amazing how red rust turns into black rust!' and 'Maintenance has become so much easier.' While chemicals can indeed 'remove' rust, they cannot 'stop' it. But ACR changes red rust to black rust and stops the corrosion of metals like tanks and pipes. I have witnessed that power with my own eyes. Among the companies that experienced the effects, some have even adopted it in their branches and affiliated facilities. Hearing them say, 'This is really good! I want it installed in the branch as soon as possible!' brings me immense joy. As I mentioned earlier, I am now in my 80s. My family tells me, 'You should retire soon,' but not at all! This is the most enjoyable time for me. I feel lucky to have encountered something I can genuinely consider my last job in life. Initially skeptical, I now believe in the effectiveness of this ACR more than anyone else. As long as I have life, I will deliver it to those who need it.
