Verification of rust prevention and longevity of air conditioning piping at the British Museum.

The red rust prevention device "NMR Pipe Protector" is recognized as the only method for prolonging the life of air conditioning pipes by preventing deterioration from red rust, capable of protecting important exhibits.

The "NMR Pipe Protector" was installed on the secondary side of the main hot water piping pump in the boiler room located in Area F of the British Museum. Before installation, the amount of red rust in the air conditioning hot water was significantly advanced, measuring 20 mg per liter. After five weeks of installation, the amount of red rust in the water decreased to 0.2 mg per liter, reducing it to one-hundredth, and the effectiveness of preventing red rust through its transformation into black rust was demonstrated. As a result, the British Museum was able to not only avoid damage and the risk of water leaks caused by red rust but also reduce the risk of red rust affecting future exhibits. Due to the high risk of damaging exhibits, construction such as replacing piping systems could not be carried out, and the use of chemicals like rust inhibitors would negatively impact the condition of paintings. Therefore, the NMR Pipe Protector was the only method that the museum could adopt. With the NMR Pipe Protector, there was no impact on the exhibits, and the British Museum was freed from the risks associated with red rust. *For more details, please refer to the PDF document or feel free to contact us.*
