Dramatically improve red water caused by red rust to make it transparent! Contributing to the stable operation of accommodation facilities.

For those struggling with scale removal in cooling towers Stubborn scale that cannot be removed even with chemicals, will be completely eliminated with 'zero chemicals'! In the hotel industry, red rust in cooling water and circulating water can lead to pipe corrosion and reduced performance of heat exchangers, potentially negatively impacting product quality and production efficiency. Especially, halting the manufacturing line can result in significant losses, making rust prevention an important issue. Aqua Crystal Ring addresses these problems by suppressing the occurrence of red rust and improving existing red water to transparency. [Usage Scenarios] - Cooling water circulation system for inkjet printers - Measures against ink clogging and nozzle deterioration - Stabilization of print quality [Benefits of Implementation] - Suppression of troubles in inkjet printers - Improvement in print quality - Reduction in maintenance costs

Applications/Examples of results

■Example 1: Major Manufacturer in Tokyo - Chiller Tank "The water that was so red and cloudy has become clear!" It has been 18 years since the installation of the heating chiller tank. The water inside the tank was red and cloudy due to rust, and previous measures had only provided temporary effects without fundamentally resolving the issue. As a result, the red rust inside the piping changed to black rust, and the red water was remarkably improved to clear. (After that, the same product was installed in the cooling chiller tank as well.) ■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!" It has been 15 years since the installation of the cooling tower. Previous rust prevention measures were ineffective, and they had somewhat given up hope, but they consulted us hoping for even a slight improvement. Four months after installation, they were very pleased, saying, "I never thought it would improve this much!" === In addition, we have over 100 cumulative installation achievements === For more details, please visit the following website (Handling Company: Archive Co., Ltd.). https://acr.archives.co.jp/
