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 simply 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 ■ Applicable to all pipe materials without the need for piping work ■ Contributes to the longevity of the entire system ■ Maintenance-free, with running costs equivalent to just the electricity of 1-2 fluorescent lights *For more details, please download the catalog or contact us.

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 over white gas pipes (galvanized steel pipes). Furthermore, from the 1980s to the present day (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 on the corrosion of the water supply pipes by removing them. 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 metals 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 metals through the water. *For more details, please refer to the PDF document or feel free to contact us.

The effectiveness of Polar as a countermeasure against hot water red water was confirmed. In large buildings and hotels, after more than 10 years, the dissolved oxygen, chlorine ions, and pH in the water cause corrosion to progress on the inner surface of the pipelines, resulting in red water due to rust in the hot water and bath, which becomes a significant operational issue. In response to such troubles, Polar significantly suppresses the progression of corrosion without the need for chemical injection, resolving the red water issue. The facts regarding this matter were evaluated by a lining contractor in the residential newspaper "Amenity." [Case Study] ■ Purpose: Confirmation of the effectiveness of Polar as a countermeasure against hot water red water. ■ Installation: One unit of Polar model "PI-40F" was installed in a bypass manner on the main pipe to treat 50% of the hot water circulation volume magnetically (installed on June 5, 1987). *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the test conducted by our company to confirm the effectiveness of Polar in removing red rust. The water tank used was made from a drum that had been utilized during fire training, and it was quite rusty both inside and out. The purpose of the test was to observe how the rust on the inside and bottom, which came into contact with Polar water, would change. During the test, the rust inside the tank (drum) caused the water to become red and murky, making the bottom invisible. However, after the test, the rust on the inner walls and bottom that had come into contact with Polar water was completely removed. It should be noted that the upper part of the inner wall, about 10 cm high, which did not come into contact with Polar water, remained unchanged from before the test. [Test Overview] ■ Duration: February 23, 1989 - March 16, 1989 ■ Location: Underground boiler room of a certain automobile dealer headquarters in Nagano City ■ Purpose - To remove the red rust (Fe203) generated inside the sample pipe by Polar and to see if it can be reduced to black rust (Fe304). *For more details, please refer to the PDF document or feel free to contact us.

Water treated with magnetic processing using a polarizer causes softening and dissolution of scale. A polarizer model "PI-15(15A)" was installed in the test equipment to investigate the softening and dissolution outflow of scale in the test pipe. Comparing before the use of the polarizer and 2.5 months after its use, it was found that softening and dissolution of the scale occurred. It is considered that it may take a considerable amount of time to remove scale solely with the polarizer, so while the primary purpose is to prevent scale adhesion, it is believed that it does not have the rapid effectiveness of chemical cleaning for removing adhered scale, but it can prevent scale buildup inside the pipes. [Test Overview] ■ Provider: Environmental Frontier Co., Ltd. (Shizuoka City) ■ Test Period: June 1, 1984, to August 15, 1984 (approximately 2.5 months) ■ Purpose: Does water treated with magnetic processing using a polarizer cause softening and dissolution of scale? ■ Method: A polarizer model "PI-15(15A)" was installed in the test equipment to investigate the softening and dissolution outflow of scale in the test pipe. *For more details, please refer to the PDF document or feel free to contact us.

Two identical cooling towers are arranged in parallel using the same source water, and both cooling towers were cleaned in the same manner before entering the test. One of the cooling towers was equipped with the Polar magnetic water treatment device "PI-40F." The other continued to operate as usual with automatic blowdown using an algae growth inhibitor. The side using the inhibitor showed a significant presence of algae throughout, with a lot of foaming in the water, while the side using the Polar device showed no algae growth at all, and the water clarity improved compared to before.

The beauty salon uses a lot of hot water. In particular, Iowa is an area with hard water (water with high calcium content), so the electric water heater's supply system was constantly required to be cleaned with acidic chemicals due to scale troubles. A "Model: PI-20F" polarizer with a connection diameter of 3/4 inch (20A) was installed for full treatment on the water supply pipe of this beauty salon. As a result, the scale (water stains) that had previously been very dirty was removed, and it became clean, surprising the customers. [Measures and Effects (Excerpt)] - Installed a "Model: PI-20F" polarizer with a connection diameter of 3/4 inch (20A) for full treatment on the water supply pipe. - The surface of the electric heater only has a soft, thick white film. - The inside surfaces and bottom of the tank also became clean, and the walls became very smooth. *For more details, please refer to the PDF document or feel free to contact us.

In 1970, a "Polar PD-15 (commonly known as Compact-1)" was installed on the water supply pipe above the faucet under the kitchen sink of Mr. Lynch's house in the UK, using a full-flow water treatment method to combat scale in the dishwasher. It has been in use for 16 years, and there has been absolutely no scale buildup, with no white calcium deposits anywhere. When compared to the dishwasher of a neighbor 20 meters away who does not have a Polar installed, the neighbor's dishwasher had scale removed in 1989, but two months later, scale reappeared on the device's floor, elements, and filter screen, resulting in a terrible condition.

The radio frequency signal transmitted from the transmitter is used to create an electromagnetic field for water treatment inside the pipe, using an electromagnetic field generation device and a ferrite ring fixed around the piping. The magnetic field is formed in a ring shape inside the pipe, perpendicular to the flow of water, while the electric field is formed radially from the center of the pipe towards the inner surface. The effective range extends 5,000 meters upstream and downstream from the installation location of the device.

We would like to present the results of an experiment conducted at the Royal Military Academy in the UK, using the electromagnetic water treatment device "Hydroflow." The method involved filling a 10L flask of a distillation water purification device with regular tap water. The water was boiled using an electric heater, and the steam was condensed to produce distilled water (pure water), with the treatment conducted in two phases: treated and untreated. The results of this test clearly indicate that Hydroflow affects the size of calcium carbonate scale crystals, revealing that larger crystals grow in water and precipitate in a short time. 【Summary of the Case】 ■ Purpose: Demonstration test of scale adhesion prevention effect ■ Device Name: Hydroflow HS38 model (for general household use, for 10-25A pipes) ■ Implementation Period: January to April 1995 (4 months) ■ Location: Royal Military Academy, UK *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a technical case where the electromagnetic water treatment device "Hydroflow" was installed to prevent scale and slime troubles in compressor cooling water and to save water. The cooling water system uses tap water as the supply, but the compressor occasionally stops due to high-pressure cut-offs, requiring chemical cleaning each time. Since the factory operates 24 hours a day, the cost of water treatment chemicals is high, and they were not being utilized. Therefore, the Hydroflow P60 (for 50A) was manually installed on the piping within the factory. As a result, it is currently being managed with manual blow-off, but chemical cleaning was done two months prior to installation, and after installing the P60, scale and slime clogged the main pipe strainer, which was cleaned once. It is now operating smoothly. 【Case Overview】 ■User Name: Major Tire Manufacturer (Kurume City, Fukuoka Prefecture) ■Purpose: Preventing scale and slime troubles in compressor cooling water and saving water ■Device Name: Hydroflow P60 (for 50A) *For more details, please refer to the PDF document or feel free to contact us.
