A case where the progression of new red rust in the air conditioning chilled and hot water piping completely stopped just 52 days after installation!
The hospital had been built for 27 years at the time, and the air conditioning chilled and warm water piping, which used galvanized steel pipes (SGP), was experiencing significant deterioration due to red rust, 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, under the same conditions, the water sampled from the air conditioning warm water showed a transparent color, and the water quality test results indicated 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 warm 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 that of the building.
