ダイワ工業 List of Products and Services

Our company has many years of experience and achievements as a comprehensive chemical manufacturer specializing in water treatment and energy-related products. We handle a wide range of comprehensive chemicals, including cooling tower water treatment chemicals such as the corrosion inhibitors "Dianol A-10" and "Dianol A-100," as well as boiler-related chemicals and wastewater treatment chemicals. 【Product Line】 ■ Cooling tower water treatment chemicals ■ Boiler-related chemicals ■ Wastewater treatment chemicals ■ Others *For more details, please contact us.

Our company analyzes the components of various scales, such as plant piping and cooling towers (water-cooled cooling towers), and proposes suitable chemicals based on the components. Since the components of various scales include a wide range of substances such as iron, calcium, magnesium, and silica, using chemicals that are not appropriate for the specific scale components will not yield effective results. If the scale in cooling towers (water-cooled cooling towers) is left untreated, it not only reduces heat exchange efficiency but can also lead to significant operational issues. Additionally, measures are necessary not only for scale prevention but also for addressing water quality deterioration caused by microbial corrosion. From component analysis of scales to testing truly effective chemicals, we go beyond merely selling chemicals and provide results tailored to our customers' conditions! Daiwa Industrial has over 50 years of accumulated experience and numerous achievements across a wide range of industries, including government agencies, power, steel, chemicals, paper, electricity, food, hotels, hospitals, and printing! *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the "Dianol Series (Corrosion Inhibitor)" that we handle. By forming a protective film on equipment and piping where cooling water flows, it effectively suppresses corrosion damage, maintaining equipment integrity, thermal efficiency, and smooth operation. When using this product, we conduct water quality tests once a month and propose optimal water management. 【Product Examples】 ■ Dianol A-101 ■ Dianol A-106 ■ Dianol A-201, etc. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Dianol Series (Scale Dispersant)" that we handle. Through chelation effects, threshold effects, and dispersion effects, it suppresses the generation of scale, demonstrating excellent effectiveness in equipment maintenance, maintaining thermal efficiency, and ensuring smooth operation. When using this product, we conduct water quality tests once a month and propose optimal water management. 【Product Examples】 ■ Dianol A-5 ■ Dianol B-21 ■ Dianol B-22, etc. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our "Dianol Series (Corrosion and Scale Dispersant)." The occurrence of corrosion and scale damage leads to material thinning and perforation of heat exchanger tubes, structural components of equipment, and piping, resulting in damage and energy waste due to decreased heat exchange efficiency, which hinders the smooth operation of equipment. Our company offers the Dianol Series, which can solve these corrosion and scale issues with a single chemical. [Product Examples] ■ Dianol A-10 ■ Dianol A-100 ■ Dianol A-101, etc. *For more details, please refer to the PDF document or feel free to contact us.

The "Dianol Series (Bactericide and Algaecide)" is a bactericide and algaecide that has extremely low corrosion to metals. When using this product, we conduct water quality tests once a month and propose appropriate water management. We also offer bactericides and algaecides that can be used as measures against Legionella bacteria, so please feel free to consult us. 【Product Examples】 ■ Dianol A-10S ■ Dianol A-380 ■ Dianol A-700, etc. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our "Dianol Series (Comprehensive Water Treatment Agent)." This all-in-one comprehensive water treatment agent possesses effects against the three major issues that occur in cooling water systems: corrosion, scale, and slime. Since it is an all-in-one solution for these issues, there is no need to handle multiple water treatment agents, which can reduce maintenance effort. [Product Examples] ■ Dianol A-410 ■ Dianol A-440 *For more details, please refer to the PDF materials or feel free to contact us.

The "Dianol Series (cleaning agents)" is a cleaning agent that demonstrates excellent cleaning effects against various scales (iron, calcium, magnesium, silica) and slime, including Legionella bacteria. In cooling towers, issues such as reduced thermal efficiency occur due to the adhesion of scale and slime to heat exchangers. Regular maintenance is important, but these issues can be improved through periodic cleaning. 【Product Examples】 ■ Dianol A-200 ■ Dianol A-300 ■ Dianol A-200SK, etc. *For more details, please refer to the PDF materials or feel free to contact us.

"Sandblasting work" is a process that uses high-pressure air to spray special sand (abrasive) to powerfully remove scale that has adhered to the inside of boilers. It can clean areas that are unreachable by manual labor without causing any damage to steam pipes or heater tubes in a short period of time. Additionally, since sandblasting is a dry method, there are no concerns about low-temperature corrosion after the work is completed, and there are no issues with wastewater treatment or corrosion occurrence that can arise after wet method construction. [Features] - Can be cleaned in a short time - No damage to steam pipes or heater tubes - Capable of cleaning areas that are unreachable by manual labor - No issues with wastewater treatment or corrosion occurrence after wet method construction *For more details, please refer to the PDF materials or feel free to contact us.

Our company provides "cooling tower cleaning" not only through chemical cleaning but also through physical cleaning methods such as high-pressure washing. In cooling towers, issues such as reduced thermal efficiency occur due to the adhesion of scale and slime to heat exchangers. As a provider of water treatment technology, we offer cleaning methods tailored to each cooling tower based on our extensive experience.
