Remove red rust! The murky red water has become so clear!

**For those troubled by red water in cooling systems** Chillers, cooling towers, piping, heat exchangers... We can improve your red, murky cooling and circulating water to a clear state! **We can solve all these concerns!** ✓ The cooling and circulating water has turned bright red ✓ Even after replacing the water, it quickly turns bright red again ✓ Red rust is occurring in the distribution pipes and heat exchangers ✓ The frequency of cleaning and maintenance is high, and you want to reduce hassle and effort ✓ You want to improve rust issues and minimize equipment damage By the way, these concerns are very common, as we have conducted over 100 cases of red rust and red water measures over nearly 20 years. Red rust tends to occur in inconspicuous places within the piping, so it's easy to postpone addressing it. However, during that time, the piping continues to weaken due to red rust. By the time you notice it, there may be holes causing water leaks, or the piping itself could break, leading to emergency repairs and the urgent shutdown of production lines, posing significant risks.

basic information

【Recommended for companies like these】 ✓ Think rust cannot be helped ✓ Don't know what to do ✓ Previous rust prevention measures have not been effective 【Three features of our product】 ■ Feature 1: Can remove rust By introducing our product, red rust in the pipes is transformed into black rust. As a result, even red water that has turned bright red can be improved to clear and transparent. ■ Feature 2: Suppresses the occurrence of red rust As long as the effects of ACR continue, they will last permanently. In other words, after installation, the environment becomes less prone to red rust, extending the lifespan of pipes and equipment. ■ Feature 3: No installation work required Simply place it in water to complete the installation. No specialized knowledge is required. Since it does not need a power supply, it can be introduced without stopping operations. 【Specifications】 - Size: Diameter 100mm, Thickness 30mm - Material: Resin (hardened polyethylene) - Accessories: Chain, zip ties - Operating temperature range: 1℃ to 80℃ - Warranty period: 3 years For information on the safety of our product (Product Safety Data Sheet/SDS), please visit our company website below. https://acr.archives.co.jp/specification/

Price information

Please send us the specifications of the equipment (such as chillers, cooling towers, heat exchangers, etc.) that are experiencing issues with red rust and red water, and if possible, current photos of the situation. We will propose the optimal plan and estimate for where and how many units should be installed.

Delivery Time

P3

※We will deliver within 5 business days after placing the order. Installation can be done on the same day the product arrives (estimated time: about 10 minutes).

Applications/Examples of results

■Example 1: Major Manufacturer in Tokyo - Chiller Tank "The water that was so red and cloudy has become clear!" Eighteen years have passed since the installation of the heating chiller tank. The water inside the tank was rust-colored and cloudy, and previous measures had only provided temporary relief without addressing the root cause, causing frustration. As a result, the red rust inside the pipes transformed into black rust, and the red water was remarkably improved to be clear. (Afterward, this product was also installed in the cooling chiller tank.) ■Example 2: Chemical Manufacturing Company in Tokyo - Cooling Tower "I had given up on the rust, but I never expected it to improve this much!" Fifteen years have passed since the installation of the cooling tower. Previous rust prevention measures had been ineffective, and they had almost given up hope, but they reached out for consultation hoping for even a slight improvement. Four months after installation, they expressed great joy, saying, "I never thought it would improve this much!" ★In addition, we have over 100 cases of improvement for cooling water and circulating water that were red and cloudy due to rust, including chillers, piping, cooling towers, and heat exchangers. We have introduced these cases with photos in our "Case Study Collection," so please download it and confirm the effectiveness for yourself. (Seeing the photos makes the effects immediately clear.)

  • Catalog news

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.
