DAIWANOL series

Water cooling tower series

What is the DAIWANOL series?

The DAIWANOL series is our original chemical series that prevents water problems in cooling towers. The cooling tower environment varies depending on factors such as location, climate, and operating conditions. Daiwa Industry has over 50 years of experience and can propose the optimal combination of water treatment chemicals.


Generally, cooling water for cooling towers is heated through a heat exchanger, cooled in the tower, and then circulated for reuse. As evaporation and splashing occur in the cooling tower, calcium and other substances contained in the cooling water become concentrated and adhere as scale, reducing heat exchange efficiency. Additionally, dust, acidic substances, and microorganisms sucked in from the outside air can cause problems such as corrosion, sludge, clogging, and algae growth in the cooling tower.

There are various products other than the DAIWANOL series.

  • PAC flocculant
  • Boiler-related chemicals and other chemicals
  • Water Treatment Filter
  • Chemical injection unit (pump, tank)
  • Automatic blowdown system

Please leave the cleaning work to us.

We undertake the following construction work [Construction business license acquired]

Cooling tower cleaning work

By adopting a cleaning method suited to the condition and purpose of each cooling tower, we can remove scale and slime and restore cooling function.


Condenser cleaning work

The condenser tubes are cleaned to remove any scale or slime that has built up, improving heat exchange efficiency and restoring the vacuum.


Boiler sandblasting work

High-pressure air is used to spray a special abrasive to remove scale that has built up inside the boiler. This restores combustion efficiency and eliminates the worry of corrosion.


Other cleaning work

We also offer a wide variety of other maintenance services to meet various needs, such as cleaning water tanks and chemical cleaning of pipes.



We remain committed to contributing to society as a trusted partner in water treatment technology.
