Cooling water (refrigeration unit and oil cooler) [Magnetic water treatment device Vol. 9]

Effect on rust on the inner surface of pipes, how effective is it against scale adhesion?

When cooling circulating water is treated magnetically with a Polar Water Conditioner, tests were conducted to determine the effectiveness against rust on the inner surface of pipes and the extent of scale adhesion. The testing method involved two identical cooling systems; one was equipped with a Polar unit, allowing the circulating water to bypass and be treated magnetically, while the other remained untreated for comparison. The inner surface of the pipes using the Polar unit showed white calcium powder crystals adhering to the uneven surface of the pipes, effectively coating them (creating a corrosion-resistant film) and suppressing the progression of rust. In contrast, the untreated side exhibited less coating from calcium powder crystals, leading to increased rust progression. [Case Study] - Installation Location: A certain public factory in Tokyo - Test Duration: 1 year from June 1983 to July 1984 - Polar Installation Position: The Polar model "PI-32F (32A)" was installed in a partial bypass method to treat more than 15% of the circulating water volume. *For more details, please refer to the PDF document or feel free to contact us.

basic information

[Test Results] - The inner surface of the test pipe (new pipe) where the polarizer was installed has a coating resembling an inner surface coating (formation of an anti-corrosion film) due to the adhesion of white calcium powder, and there is almost no progression of rust observed. - Additionally, this calcium powder is soft and can be removed with water washing. - On the other hand, the untreated pipe shows progression of rust and no inner surface coating is observed. *For more details, please refer to the PDF document or feel free to contact us.
