On November 23, 2006, three NMR pipe protectors were installed in all iron circulation hot water and air conditioning piping systems at the Royal Garden Hotel. Before the installation of the NMR pipe protectors, the iron content in the hot water was very high at 2.79 mg/l, indicating significant red rust deterioration. After 25 days of installing the NMR pipe protectors, the iron content in the hot water dropped to 0.016 mg/l, a reduction of nearly 95% compared to before installation, and well below the drinking water standard of 0.2 mg/l, demonstrating the rust prevention effect of the NMR pipe protectors. This indicates that the NMR pipe protectors successfully prevented the occurrence of new red rust and transformed it into black rust. Additionally, leaks that had occasionally occurred prior to the installation of the NMR pipe protectors have not happened at all in the past 14 years since their installation. Thus, by introducing the NMR pipe protectors, the piping at the Royal Garden Hotel has become usable for as long as the building continues to be in use. The hotel management is very satisfied with the results of the NMR pipe protector installation, and the Royal Garden Hotel is considering the additional installation of NMR pipe protectors for the air conditioning chilled water piping in the future.
