Here is an example of the effectiveness of "Pure Dora" against red rust and red water. Before the installation of "Pure Dora," all parameters closely related to red water—"iron, color, and turbidity"—were in a terrible state, failing to meet water quality standards (the passing criteria for drinking water). However, by the third month after installation, the values adapted to the water quality standards, and they have maintained a good condition since then. Additionally, black rust (magnetite) began to form between the red rust and the pipe wall, growing into a strong black rust of about 750 cps after 12 months. It has been demonstrated that "the longer it is used, the more effective it becomes." [Case Study] ■ Building: Public apartment complex in Aichi Prefecture (7 stories, 48 units) ■ Age: 24 years at the time of installation ■ Piping: VLP pipes ■ Device Model: Water supply pipe PD-6400 type (100A) Pumping pipe PD-4200 type (65A) *For more details, please refer to the catalog or feel free to contact us.

We would like to introduce a case study on the scale prevention measures for intercoolers using "Pure Dora." Before the installation of "Pure Dora," chemical treatments were being used, but the scale prevention and removal effects were not satisfactory, leading to additional labor for cleaning. After the installation of Pure Dora, even after 10 months, the intercooler maintained a clean state similar to when it was being cleaned regularly. The cooling efficiency improved, and the reduction of blowdown water was also achieved. This resulted in lower maintenance costs, chemical expenses, and wastewater treatment costs! [Case Study] ■ Intercooler ■ Scale and slime accumulated in each hole ■ Chemical treatments were ineffective, leading to the introduction of "Pure Dora." *For more details, please refer to the catalog or feel free to contact us.

"Pure Dora" is a magnetic water treatment device that is optimal for addressing red water issues in water supply pipes, cooling water pipes, and air conditioning ducts. It transforms red rust, the cause of red water, into magnetite (black rust), stopping red water while protecting the piping. Additionally, it softens hard, stubborn scale through magnetic treatment, making it easier to remove and less likely to adhere. The installation work of the device is completed in a short time, minimizing the inconvenience to daily life and the decrease in productivity caused by construction. [Features] ■ Rust prevention and scale prevention/removal effects are semi-permanent ■ Maintenance-free and zero running costs ■ Short installation time for the device ■ Established know-how for accurate model selection ■ Contributes to obtaining ISO 14000 series certification *For more details, please refer to the catalog or feel free to contact us.

Since it uses an inline method that cuts and connects the piping, it can efficiently treat water with magnetic processing. In addition to addressing issues like red water, rust, and scale, measures against bacteria and algae are also available as options. The main problems related to water can be solved with the magnetic water treatment device, Pure Dora.
