Extend the lifespan of your current water pipes and air conditioning pipes for over 40 years! By converting red rust to black rust, we can rehabilitate the pipes and eliminate the need for expensive pipe replacements.

■Features - Cumulative installation record of over 4,300 buildings as of March 2022 - Extends the lifespan of water pipes for over 40 years, up to the lifespan of the building - Installation costs are about 1/5 to 1/10 of pipe replacement work - Patented in Japan and the United States, registered with the Ministry of Land, Infrastructure, Transport and Tourism's NETIS new technology utilization system - No need for water outages, no running costs (power supply or chemicals) required - Installed on the outside of pipes, allowing for short-term installation and ensuring hygiene - Comes with a product warranty ■Product Overview By converting red rust that occurs inside old pipes into black rust, we improve and reinforce the pipes, effectively rehabilitating them. This also prevents the new occurrence of red rust. While red rust deteriorates pipes, black rust has entirely different properties. Black rust has a smaller volume than red rust, is more robust, and is insoluble in water, which reinforces the pipes and extends their lifespan by over 40 years. Typically, the lifespan of pipes is shorter than that of buildings (about 20 years), but this solution allows for an extension up to the lifespan of the building without the need for expensive pipe replacement. ■ Japan System Planning Co., Ltd. ■ Toll-free number: 0120-320-390 Official website: https://www.jspkk.co.jp/jp/contact/

• Water Treatment

We have published numerous costs for when you actually implement it. We will provide a "cost comparison table" that clearly shows the comparison with the costs of updating the piping!

~For those who are troubled by such issues~ ■ I don't have the money to rebuild or update the plumbing... ■ I want to quickly address the red water and plumbing clogs... ■ Water outage work is quite a hassle... ★ Please download and view the "Case Studies" PDF document below. ★ Feel free to contact us if you want to know a rough estimate of the costs!

• Piping Equipment

Incredible... Over 4,300 installations! Even old piping can avoid the need for replacement thanks to rust prevention effects! We will introduce various case studies from different buildings all at once.

～Recommended for the following people～ ■ Those who want to continue using old piping ■ Those who do not want to cut or grind the piping ■ Those who prefer to avoid water outage construction ■ Those who do not want to spend much time or money…! The introduction cost is less than 1/5 to 1/10 of the cost of pipe replacement! *Please download the PDF materials below to view the "Case Studies." *Feel free to contact us if you want to know a rough estimate!

• Water supply facilities

A condominium that used an NMR pipe protector to prevent red rust in the water supply pipes, reducing the piping renewal costs to one-tenth, and used the remaining funds to install a new elevator.

The "NMR Pipe Protector" is a groundbreaking device for apartments and hospitals struggling with the issue of red rust in their piping, and it has received great acclaim. The introduction cost of the NMR Pipe Protector is about 1/5 to 1/10 of the cost of pipe replacement, allowing for a cost reduction of approximately 80 to 90%. At "Cosmo Kajigaya Le Seine," the introduction of the NMR Pipe Protector created financial flexibility, and they began considering the installation of a new elevator, which was a frequent request from residents. It was deemed financially feasible, and a proposal for the installation of the NMR Pipe Protector along with the new elevator was presented together at an extraordinary general meeting, where it was approved. Thus, the introduction of the NMR Pipe Protector brings various benefits to each facility. In addition to its effects on maintaining and improving water quality, it also makes a significant contribution in terms of cost. *For more details, please refer to the PDF document or feel free to contact us.*

• Renovation and repair methods

The installation of the rust prevention device "NMR Pipe Protector" on the water supply pipes has been confirmed through long-term verification that the black rust formation from red rust inside the pipes improves the condition of the piping every year.

The "Lions Mansion Koshigaya North" located in Koshigaya City, Saitama Prefecture, introduced the NMR Pipe Protector in November 2010. This successfully reduced the cost of pipe maintenance to one-third of the amount originally planned for lining work in the long-term repair plan. Before the installation of the NMR Pipe Protector, and one year, five years, and ten years after installation, the red rust blockage rate at the dissimilar metal joints, where red rust deterioration progresses the most, was continuously inspected, confirming that the red rust blockage rate decreased over time. This indicates that the red rust is gradually transforming into black rust, which is one-tenth the volume. This has proven that the water supply pipes can be extended to the lifespan of the building. The management association effectively utilized the saved budget for LED lighting upgrades and other repairs. In addition to the LED lighting upgrades, the renewal of elevators is also being considered in the future. As a result, the NMR Pipe Protector has become a savior for the condominium. It has significantly reduced the costs of pipe maintenance, allowing the remaining budget to be allocated to other building facilities. **Results of the NMR Pipe Protector:** - No growth of red rust was observed in the endoscopic survey conducted six years after installation. - A reduction in the volume of red rust was observed, indicating progress in the transformation to black rust.

Profect Co., Ltd. will hold a seminar on October 3rd (Friday) themed around the IT Implementation Subsidy 2025 and our developed and sold production management system "TED." This year's IT Implementation Subsidy has seen a significant decrease in the acceptance rate compared to previous years. Many companies are struggling with the situation of having wanted to implement IT tools but being rejected. In this seminar, we will explain why the acceptance rate has dropped, the background behind it, and the key points for being accepted. Additionally, we will introduce our initiatives that have achieved a 100% acceptance rate so far this year and the reasons why our production management system "TED," registered as an IT tool, is chosen. To accommodate busy schedules, this seminar will be held in a hybrid format, allowing for both in-person attendance and online participation via Zoom. Please choose your preferred method of participation according to your convenience. If you are currently considering applying for the IT Implementation Subsidy or are interested in production management, we encourage you to join us. We sincerely look forward to your application.

An international forum aimed at promoting the circular economy and closed-loop economy, "Closed Loop Recycle Forum 2025 (hereinafter referred to as CLRF2025)," will be held for two days from November 25 (Tuesday) to 26 (Wednesday) at The Oriental Terrace in Chuo Ward, Hamamatsu City, Shizuoka Prefecture. In Europe, closed-loop recycling practices are already advancing. We have organized this international forum as a platform to connect the forefront of Europe with Japan's challenges, striving for a future that balances economic viability and environmental sustainability. A total of 12 speakers, including Chairman Kajiwara of the Waste and 3R Research Foundation and Director Kaneko of the Ministry of the Environment's Container and Packaging Recycling Division, along with leading recycling operators and researchers from Japan and Europe, will present advanced examples of the circular economy and closed-loop economy. Furthermore, through discussions on the feasibility and challenges of implementation in Japan, we will explore hints for sustainable business models that companies and local governments should aim for.
