A case where the progression of new red rust in the air conditioning chilled and hot water piping was completely halted just 52 days after installation!
The hospital, which was 27 years old at the time, was using galvanized steel pipes (SGP), and the red rust deterioration in the air conditioning chilled and hot water piping was very advanced, raising concerns about leaks. Before the red rust corrosion could progress any further, a red rust prevention piping extension device called "NMR Pipe Protector" was installed. After 52 days of installation, the water sampled from the air conditioning hot water system under the same conditions was clear, and the water quality test results showed that the iron ion concentration in the water was 0.27 mg/l, which is below the water quality standard value (1.0 mg/l) set by the Japan Refrigeration and Air Conditioning Industry Association. If this product continues to be installed in the hospital's air conditioning chilled and hot water piping, it has been verified that the red rust deterioration and leaks in the piping will be completely prevented, extending the piping's lifespan to match the building's lifespan. [Overview of Installation] ■ Hospital Location: Sendai City, Miyagi Prefecture ■ Hospital Overview: 27 years old, 5 stories, 199 beds ■ Installation Work: December 25 to 28, 2006 *For more details, please refer to the PDF document or feel free to contact us.
