The Non-Scaler is the world's only device that solves calcium scale solidification and adhesion problems without using chemicals. The Non-Scaler oxidizes dissolved calcium in water as hydroxide through blades inside the device, transforming it into calcium carbonate microparticles (nanoparticles) that are dispersed and flow in the water. Once transformed into calcium carbonate nanoparticles, they do not change even when heat is applied, preventing issues such as damage to pump blades and clogging in heat exchangers caused by calcium scale. ■Features - Excellent calcium adhesion prevention effect - 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 piping - No chemicals required - No external power supply needed - Compatible with pipe sizes from 15A to 250A *You can download materials explaining cost reduction methods. *Please feel free to request a free estimate via the inquiry form.

【Effects After Installation】 ■ Prevention of damage to the impeller of the cooling water pump due to calcium crystals ■ Prevention of calcium scale solidification and adhesion inside the pump ■ Reduction of line stoppage frequency from 1.2 times per month due to pump disassembly and cleaning, leading to increased productivity! Our factory was experiencing a situation where the line stopped every month (20 times/year) due to strong calcium scale adhering inside the pump, causing internal damage and requiring disassembly and cleaning. After the installation of the "Non-Scaler," there have been no line stoppages for over six months. Upon checking the scale condition inside the pump casing, it was found to be soft and in fine particle form, rather than forming strong calcium scale. By preventing damage to the pump caused by calcium scale, we have not only avoided line stoppages but also achieved significant reductions in maintenance costs. *For more details, please refer to the PDF document or feel free to contact us.

The cooling water used in open-type central air conditioning cooling towers has its calcium concentration rise to about 7 to 10 times that of the make-up water (source water) due to evaporation, resulting in the formation of hard calcium carbonate crystals on the surface of the cooling fins outside the cooling tower, which reduces cooling efficiency. The non-scaler, when installed in the make-up water piping, transforms dissolved calcium hydroxide in the water into calcium carbonate nanoparticles, dispersing them in the water and preventing calcium from solidifying and adhering to the cooling fins of the cooling tower. *For more details, please refer to the PDF document or feel free to contact us.*

The heat exchanger at the chemical plant was subject to calcium scale buildup, necessitating disassembly, cleaning, and washing every five months. When scale accumulated on the heat exchanger, it reduced cooling efficiency and negatively impacted product quality. After installing a "non-scaler" following the cleaning of the heat exchanger, there was no calcium carbonate buildup on the hot water piping even after five months, resulting in maximum cooling effectiveness of the cooling water and maintaining the lowest defect rate for products. Additionally, the need to stop the plant every five months to scrape off calcium carbonate from the outside of the hot water piping was eliminated, leading to a reduction in product defect rates and an improvement in productivity. *For more details, please refer to the PDF document or feel free to contact us.*

Calcium scale inevitably adheres to the interior of hot water boilers and similar equipment. To reduce the adhesion of calcium scale, traditionally, ion exchange resins have been used to soften the water by removing calcium ions before producing hot water in the boiler. The residual calcium in the water crystallizes as insoluble calcium carbonate within the boiler and adheres to it. Traditionally, strong alkaline agents were added to the boiler to prevent the formation reaction of calcium carbonate. However, strong alkaline hot water is highly corrosive to metals, leading to corrosion and deterioration of the boiler itself, internal piping, and hot water piping, which shortens the lifespan of the boiler and connected piping systems to around 10 years. The calcium scale prevention device "Non-Scaler" reacts the calcium in the water with free carbon dioxide within the Non-Scaler, forcibly transforming it into fine particles of calcium carbonate that are dispersed and flow in the water. Once calcium carbonate is converted into fine particles, it remains unchanged even under the high temperature and pressure conditions inside the boiler, flowing in its particulate state. Additionally, the effects of corrosion and deterioration caused by strong alkaline agents are eliminated, making it possible to extend the lifespan of the boiler and hot water piping by more than double.

**Effects After Installing the Non-Scaler** - Eliminated the decrease in flow rate caused by calcium crystals - Both flow rate and temperature remain stable even after 4 months - No need for disassembly cleaning, significantly reducing maintenance time and burden At our factory, we used groundwater containing a high level of calcium (180 mg/L), which made it easy for calcium scale to adhere inside the valves, frequently causing a decrease in flow rate. As a countermeasure, we introduced a coil electromagnet device two years ago, but there was hardly any observed effect in preventing scale. Therefore, we newly installed a "Non-Scaler," and clear improvement effects were confirmed. Before installation, due to the decrease in flow rate and the accompanying drop in temperature, we had to perform disassembly cleaning of the valve plates approximately every 4 months, which took about 36 hours each time. However, after the introduction of the Non-Scaler, even after 4 months, there were no issues with the decrease in flow rate or temperature, and disassembly cleaning of the valves became unnecessary. Current maintenance now only involves lightly tapping the outside with a rubber hammer to remove softened deposits, leading to a significant reduction in work time. *For more details, please refer to the PDF document or feel free to contact us.*

**Effects After Installing the Non-Scaler** - Acid cleaning twice a year is no longer necessary, maintaining productivity without line stoppages. - Significant reduction in cleaning and maintenance costs as well as labor expenses. - Contributes to the longevity of piping equipment. In our factory, we use groundwater as cooling water, which has caused calcium carbonate scale (hard crystals) to adhere to the piping on the secondary side of the pump, necessitating acid cleaning twice a year. During this acid cleaning process, the factory line had to be temporarily halted, leading to significant economic losses due to production stoppages. To address this issue, a "Non-Scaler" was installed on the secondary side of the pump piping. Before installation, as seen in the photos, thick white scale was heavily adhered inside the piping, making removal extremely difficult. However, six months after the installation of the Non-Scaler, there was almost no scale adhesion observed inside the piping, and the effects were clearly evident, allowing for substantial cost reductions. *For more details, please refer to the PDF document or feel free to contact us.*

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.
