**"For those struggling with scale removal in cooling towers"** Stubborn scale that can't be removed even with chemicals, will be completely eliminated with "zero chemicals"! **"We can solve all these problems!"** ✓ The scale is really bad. ✓ 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 have increased. ✓ I want to reduce chemical costs. **"Five benefits that make us the choice"** ■ Benefit 1: Significantly improved cooling efficiency! We remove scale and restore the original cooling performance. ■ Benefit 2: No chemicals, power supply, or construction needed! Just place it in the water. No special work is required. ■ Benefit 3: Maintenance-free Simply wipe the main unit with a cloth when it gets dirty. Maintenance is completed 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 supply. ★ Moreover, to prevent the reattachment of scale, the lifespan of the equipment and piping inside the cooling tower is greatly extended.

Applications/Examples of results

■Example 1: 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 proceeded with the installation. As a result, scale removal and rust suppression were achieved, leading to an extended lifespan for the cooling tower and significant cost savings. (Afterward, installations were also made at related hotels in Hakone and Ito.) ■Example 2: 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 decline in cooling efficiency. They were troubled as 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 record of over 100 installations, regardless of size (large, medium, or small). We provide detailed introductions with photos in our 'Case Study Collection,' so please download it now to confirm its effectiveness.
