[Case Study of Pipe Protector] St. Thomas Hospital and Coil-Type Electromagnetic Device
Unexpected Facts about Coil-Type Electromagnetic Devices and Examples of Pipe Protectors and Non-Scalers
1. Regarding the effectiveness of rust prevention (anti-corrosion) In the UK, coil-type electromagnetic devices are primarily used as a measure against calcium scale, and their effectiveness in preventing red rust has not been recognized. In fact, at St. Thomas' Hospital, famous for Florence Nightingale and where the NHS headquarters is located, this device was introduced into the hot water piping, but it showed no anti-corrosion effect, and red rust deterioration was progressing. As a result, an NMR pipe protector was installed in 2005. Before installation, the hot water contained a high concentration of iron ions, but after one month, the concentration significantly decreased, halting the progression of red rust deterioration and confirming a change to insoluble black rust. Although coil-type electromagnetic devices are also sold domestically, please be aware that their effectiveness against red rust has not been confirmed. 2. Regarding the effectiveness of calcium scale prevention Coil-type electromagnetic devices are also sold domestically as scale prevention devices, but in a major food factory where they were introduced, they failed to prevent scale adhesion within the pumps. As a result, a non-scaler was adopted, completely preventing adhesion. Disassembly and cleaning, which were previously required every few months, are no longer necessary. If you have not achieved results with coil-type devices, please consider introducing a non-scaler.
basic information
**What is the NMR Pipe Protector?** It is the world's only red rust prevention device that reduces and converts red rust (iron(III) oxide) in pipes into insoluble black rust, preventing the progression of red rust. It stops the deterioration of red rust in water supply and hot water pipes, extending the life of the piping. **Features** - Converts red rust in pipes to black rust and halts deterioration - Prevents the occurrence and progression of red rust in pipes - Eliminates the need for complete pipe replacement in buildings - Adopted in numerous medical and public facilities, as well as condominiums **What is the Non-Scaler?** It is the world's only device that solves calcium scale adhesion problems without using chemicals. By contacting and oxidizing calcium dissolved in water as hydroxide on blades within the device, it transforms it into calcium carbonate microparticles (nanoparticles) that are dispersed and flow in the water. **Features** - No chemicals or external power supply required - Compatible with pipe sizes from 15A to 250A - Prevents calcium adhesion when installed in the make-up water pipe of cooling towers - Prevents damage to pump blades - Prevents clogging in heat exchangers - Prevents calcium adhesion in pipes
