Royal Garden Hotel, UK - Measures for preventing red rust and water leakage in air conditioning and hot water piping.
Case studies of introducing NMR pipe protectors for preventing red rust and extending the lifespan of hotel air conditioning and hot water piping.
The Royal Garden Hotel London, famous as a five-star hotel in London, was built in 1965 and currently has 400 rooms. Due to the iron pipes in the hotel's hot water circulation system, red water was occurring from the taps every morning. To prevent rust and leaks in the pipes and extend their lifespan, an NMR Pipe Protector was installed. Before the installation of the NMR Pipe Protector, the iron content value due to red rust in the hot water pipes during nighttime was very high at 2.79 mg/l. However, 25 days after the installation of the NMR Pipe Protector, it decreased to 0.016 mg/l, and further decreased to 0.013 mg/l 36 days after installation, falling below the water quality standard of 0.2 mg/l set by UK water regulations. This reduction was achieved as the existing red rust in the pipes was reduced to black rust, which is an insoluble volume of 1/10 in water, thereby demonstrating the anti-corrosion effect of the air conditioning and hot water pipes and extending the lifespan of the piping.

basic information
At the Royal Garden Hotel, a follow-up survey was conducted 14 years after the installation on June 29, 2020, which demonstrated that the iron content due to red rust in the hot water supply piping was 0.00 mg/l, indicating that all red rust in the pipes had been reduced to black rust. It has been confirmed that this hot water supply piping will not deteriorate due to red rust in the future, extending the lifespan of the piping to match that of the building. Additionally, with the installation of the NMR Pipe Protector, the maintenance costs for the piping have reduced to just 5% of the costs for piping replacement, allowing the hotel to save over 95% on piping maintenance expenses. ■■■■■ Japan System Planning Co., Ltd. ■■■■■ Toll-Free Number: 0120-320-390 <Free Material Request / Inquiries> https://www.jspkk.co.jp/jp/contact/
