Pipe rust prevention, a UK five-star hotel has introduced NMR pipe protectors.

The red rust prevention device "NMR Pipe Protector" prevents red rust in air conditioning pipes, prevents leaks, and extends the lifespan of the pipes by 40 years.

At the Millennium Hotel London Mayfair, urgent measures were needed to address corrosion due to red rust in the air conditioning hot water piping. The chosen solution was the 'NMR Pipe Protector', which can be implemented at less than one-tenth the cost and has a low environmental impact while preventing red rust early on. Before installation, the iron content in the circulating water of the air conditioning hot water piping showed a very high value of 15.70 mg/l due to the progression of red rust deterioration and leaching. After re-examination six weeks post-installation, the iron content decreased to 0.16 mg/l, demonstrating that the amount of iron leached into the water reduced to about one-hundredth compared to before installation, confirming the effectiveness of red rust prevention. Thus, the water quality of the circulating water in the air conditioning hot water piping recovered to a completely acceptable level. One of the significant reasons for choosing the NMR Pipe Protector is that it is a very eco-friendly red rust prevention device. It can rehabilitate old piping that has been in use for many years, extending the lifespan of the building. Replacing the piping would result in significant CO2 emissions due to the disposal of the old pipes, so the NMR Pipe Protector, which allows for the continued use of old piping, has a very low environmental impact. *For more details, please refer to the PDF document or feel free to contact us.*
