ダイワ工業 List of Products and Services

Daiwa Industrial handles various construction projects, including cooling tower maintenance, condenser maintenance and regular inspections, boiler maintenance and regular inspections, and filtration equipment maintenance and replacement. The "cooling tower cleaning project" employs cleaning methods (chemical cleaning or high-pressure cleaning) suited to the condition and purpose of each cooling tower, removing scale and slime to restore cooling functionality. Additionally, the "boiler sandblasting cleaning project" uses high-pressure air to spray special sand (abrasive) to powerfully remove scale adhered to the inside of the boiler, restoring combustion efficiency. There is no concern about corrosion, and the construction period can be shortened. 【Features】 <Cooling Tower Cleaning Project> ■ By adopting cleaning methods (chemical cleaning or high-pressure cleaning) suited to the condition and purpose of each cooling tower, scale and slime are removed, restoring cooling functionality. <Condenser Cleaning Project> ■ Cleans the small tubes of the condenser, removing adhered scale and slime. ■ Cleaning the condenser increases the heat exchange efficiency of the condenser and restores the vacuum level. *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. [Cleaning Case Examples] ■ High-pressure cleaning work ■ Chemical cleaning work *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our "Piping Cleaning Work." With chemical cleaning, we can clean pipes without disassembly, allowing for both reduced construction time and cost savings. As a provider of water treatment technology, we offer cleaning methods tailored to each type of piping based on our extensive experience. [Features] ■ Ability to clean pipes without disassembly ■ Possible to reduce both construction time and costs *For more details, please refer to the PDF document or feel free to contact us.

We provide not only standard high-pressure cleaning but also a more powerful cleaning service for condensers that can effectively remove scale and slime. By cleaning the condenser, the heat exchange efficiency of the condenser is improved, and the vacuum level is restored. As a provider of water treatment technology with extensive experience, we can propose cleaning methods tailored to each condenser, so please feel free to consult with us. 【Examples of Cleaning Applications】 ■ Condensers for steam turbines in power generation facilities ■ Various condensers for marine use ■ Heat exchangers and coolers in oil and chemical plants ■ Coolers for large air compressors *For more details, please refer to the PDF document or feel free to contact us.
