ドーラ Product Lineup

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, including "iron, color, and turbidity," were in a terrible state that did not meet water quality standards (the passing criteria for drinking water). However, by the third month after installation, the values adapted to water quality standards, and the good condition has been maintained since then. Additionally, black rust (magnetite) began to form between the red rust and the pipe wall, growing into a strong black rust of approximately 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 pipe ■ Device model: Water supply pipe PD-6400 type (100A) Lift 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 effectiveness in preventing and removing scale was not satisfactory, leading to additional labor for cleaning. After the installation of Pure Dora, even after 10 months, the intercooler maintained a clean condition similar to when it was being cleaned regularly. The cooling efficiency improved, and the reduction of blowdown water was achieved. We realized cost reductions in maintenance, chemical expenses, and wastewater treatment! [Case Study] ■ Intercooler ■ Scale and slime accumulation 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 ideal 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 also protecting the piping. Additionally, it softens hard, stubborn scale through magnetic treatment, making it easier to remove and harder to adhere. The installation work for the device is completed in a short time, minimizing the inconvenience to daily life and reducing productivity loss due to 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 red water, rust, and scale, options for dealing with bacteria and algae are also available. The main issues related to water can be resolved with the magnetic water treatment device, Pure Dora.
