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

The NMR pipe protector is the only one in the world that transforms red rust inside pipes into black rust, enhances pipe strength, reduces repair costs by 90%, and extends the lifespan of pipes by over 40 years.

Today, as the entire society is changing due to the new coronavirus, one of the most affected industries is the hotel industry. With a decrease in guests, inability to accept banquet orders, and restrictions on dining in restaurants, income has drastically reduced. When issues such as leaks caused by rust in plumbing due to aging buildings arise, the cost of necessary plumbing updates for repairs becomes extremely high, forcing hotels to consider borrowing from banks or selling the property. The NMR Pipe Protector, a plumbing longevity device, can reduce that cost to less than one-tenth. Even if a sale is considered, the amount will be deducted by the plumbing update costs that will arise in the near future. Hotels that are over 30 years old cannot avoid this problem sooner or later. The only solution to this issue is to compress plumbing update costs to one-tenth to one-fifteenth, extend the plumbing lifespan by over 40 years, and eliminate the need for long-term closures (which require at least six months for air conditioning plumbing updates) by introducing the NMR Pipe Protector. By using the world's only rust prevention device, the "NMR Pipe Protector," which transforms internal red rust into black rust, improves plumbing strength, and extends plumbing lifespan by over 40 years, plumbing update costs can be reduced by more than 90%.
