Magnetic Water Treatment Device "Muzatsu" <Case Study Presentation>

A proposal for cooling tower managers who are fighting with long-term chemical inputs.

To the engineers who have been fighting for a long time with the long-term, economic, and management operations of cooling towers, are you still forced to use chemical treatments? Regarding the issues of scale, slime, red rust, and algae, which are essential to the operation of cooling towers, I speculate that the current specific measures are primarily chemical treatments or maintenance through manpower. Therefore, we have a proposal from Toko. The countermeasures for the 3S issues of scale, slime, and red rust in water have already been completed. An effective countermeasure is the utilization of water. This is a strategy based on understanding water pressure, flow, and volume, and there is no risk of failure. Cooling tower engineers, please consider this low-risk, high-return strategy. There will be no charge if results are not achieved. You can use it with confidence. *You can view materials with case studies from the "PDF Download." Please feel free to contact us.

"Scale Adhesion Prevention" Electromagnetic Water Treatment Device 'Hydroflow' *Made in the UK

Maintenance-free! Water treatment device for corrosion prevention, scale adhesion prevention, rust prevention, algae control, and slime prevention.

The electromagnetic water treatment device "Hydroflow" is a device that treats water by forming an electromagnetic field inside various types of pipes. By applying the principle of a transformer, it induces a magnetic field and electric field perpendicular to the water flow inside the pipe through a ferrite ring wrapped around the outside of the pipe, which is activated by electromagnetic waves generated from the main unit simply by being attached to the outside of the piping. This effect is propagated through the water, acting on scale and other issues up to 5000 meters upstream and downstream. 【Features】 ■ Prevents scale adhesion and addresses rust without chemicals ■ Compatible with all types of piping without the need for installation work ■ Contributes to the longevity of the entire system ■ Maintenance-free, with running costs equivalent to just the electricity of one or two fluorescent lights *For more details, please download the catalog or contact us.

Case Study on the Corrosion Prevention Effect of Chilled Water in Air Conditioning Systems [Magnetic Water Treatment Device Vol. 6]

Installed on the supply header outlet side! An example showing a dark brown color compared to the untreated side.

There are two comparison devices for the internal pipe investigation; one utilizes a polarizer, while the other does not. A comparative inspection was conducted under conditions without the use of a polarizer. One unit of the polarizer model "PI-50F (2”)" was installed on the discharge side of the supply header for cold and hot water, with partial circulation treatment performed using the polarizer. After treatment, clearly old scale and rust dissolved and flowed out, forming a magnetite anti-corrosion coating inside the pipe, which appeared smoother and exhibited a dark brown color compared to the untreated side. The untreated side showed signs of corrosion and scale adhesion. [Case Study] - Installation Date: December 1985 - Purpose: Anti-corrosion and anti-scaling for cold and hot water equipment - Installation Method: The polarizer model "PI-50F (50A)" was installed on the outlet side of the supply header - Treated Water Volume: More than 5% of the total circulating water volume was treated *For more details, please refer to the PDF document or feel free to contact us.

About the cause of red water (300 households) [Magnetic water treatment device Vol. 2]

We will introduce examples of conducting water main extraction in various housing complexes and investigating corrosion within the pipes!

Since the 1970s, as a measure against red water in buildings constructed after that period, the Ministry of Construction has guided the increased use of PVC-lined pipes instead of white gas pipes (zinc-coated steel pipes). Furthermore, from the 1980s to the present day in 2002, many buildings, apartments, and general residences have experienced occurrences of red water every morning. As a result, in various housing complexes, investigations were conducted by removing the water supply pipes to examine corrosion inside the pipes. The findings revealed that most of the corrosion inside the pipes was caused by the potential difference between dissimilar metals at the valves and pipe joints, as well as damage to the PVC lining seals. It was determined that the dissolved oxygen in the water reacts electrochemically with the metal through the water. [Causes] ■ Most of the corrosion inside the pipes is due to the potential difference between dissimilar metals at the valves and pipe joints, and damage to the PVC lining seals. ■ The dissolved oxygen in the water reacts electrochemically with the metal through the water. *For more details, please refer to the PDF document or feel free to contact us.
