Is there anyone else who wants to try the method that completely removes scale from the cooling tower?

**For those struggling with scale removal in cooling towers** Stubborn scale that won't come off even with chemicals, will be completely removed with "zero chemicals"! **We can solve all these problems!** ✓ The scale is just terrible. ✓ Cooling efficiency has decreased, and there are occasional abnormal shutdowns. ✓ The filler is clogged with scale. ✓ It’s hard to remove even with chemicals. ✓ Maintenance efforts and frequency are increasing. ✓ I want to reduce chemical costs. **Five benefits of choosing us** ■ Benefit 1: Significantly improved cooling efficiency! We remove scale and restore the original cooling performance. ■ Benefit 2: No chemicals, power, or construction required! Just place it in water. No special work is needed. ■ Benefit 3: Maintenance-free Just wipe the main unit with a cloth when it gets dirty. Maintenance is complete in one minute! ■ Benefit 4: Reduced running costs No need for chemicals, electricity, or additional maintenance costs. Significantly cut expenses. ■ Benefit 5: Environmentally friendly Contributes to reducing waste and CO2 emissions with zero chemicals and power. ★ Moreover, to prevent the reattachment of scale, the lifespan of the equipment and piping inside the cooling tower will be greatly extended.

Applications/Examples of results

■Example 1: A major hotel in Tokyo - Cooling tower for air conditioning (1800RT) A large cooling tower that has been in operation for 25 years. The cooling efficiency had significantly declined due to scale and rust, and they were considering replacing the cooling tower. Including disposal, new installation, piping work, and losses due to downtime, the estimated cost was about 200 million yen. They decided, "It wouldn't be too late to try this product first," and installed it. As a result, they achieved scale removal and rust suppression, extending the life of the cooling tower and significantly reducing costs. (Afterward, installations were also made at related hotels in Hakone and Ito.) ■Example 2: A major ice manufacturer in Saitama - Cooling tower (125RT) A cooling tower that had been in operation for 18 years. A significant amount of scale had accumulated on the filler, leading to a deterioration in cooling efficiency. They were troubled because the scale could not be removed even with chemical treatment. About 10 months after installation, approximately 20 kg of scale was removed, and cooling efficiency was restored. (Afterward, they also installed it on another cooling tower.) ★In addition, we have a cumulative total of over 100 installation cases, regardless of large, medium, or small sizes. We provide detailed introductions with photos in our 'Case Study Collection,' so please download it now to confirm its effectiveness.

We have compiled examples of rust removal and rust prevention for chillers!

  • Catalog news

We also remove and suppress 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 excels in scale removal 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, there are often cases where the water inside the chiller turns bright red (red water). By using ACR, you can convert red rust into black rust, improving the murky red cooling water to clear. This is achieved without any use of chemicals and does not require a power supply. ◆◆ We have received a lot of feedback ◆◆ Recently, we have been receiving many inquiries about rust in chillers and piping, in addition to scale removal from cooling towers. In response, we have compiled our past achievements and case studies. Please see for yourself how the bright red water has turned clear.
