In particular, the scale comprised of calcium, magnesium, silica, etc., in cooling water is a major issue among contaminants accumulated inside heat exchangers.
These components not only are hard to remove once stuck inside piping, but also lower the operating efficiency of facilities together with mounting costs caused by increasing amounts of water treatment chemicals and makeup water used.
Electrolytic scale removing device “WET” developed by us is a maintenance tool that reduces scale troubles in cooling water circulation systems by forcibly removing scale components to keep and improve the quality of water.
Installation of “WET” can be expected to offer a wide range of efforts.
Outline of “WET”
“WET” is a device to lower the scale component concentration in cooling water by forced precipitation in the tank through electrolysis of cooling water/makeup water in cooling water circulation system(s) (separating and taking out solid components in liquid).
Since the scale components contained in cooling water/makeup water can be removed by this, the amounts of water treatment chemicals and makeup water used can be reduced.
Water can be kept clean without environmental load as it is nonchemical.
Mechanism of “WET”
A part of flowing cooling water is taken in the tank of “WET” and scale components contained in cooling water, such as calcium, magnesium, and silica, are forcibly separated, solidified, and removed through electrolysis.
Solidified scale is to be periodically removed from the tank every three months to one year as a guide.
In some locations, scale as much as 15kg develops in two months.

We offer rental free electrolytic scale removing device “WET” on a trial basis to customers that make a request.
* Only new WET can be rented out for free for one month.
Advantages of use of trial “WET”
● Feeling the effects
Through actual use, you can feel the effects of removing scale from cooling towers and piping. You can see the scale with your own eyes because scale components in water are precipitated in the tank.
● Lightweight and easy to carry around
The main body, for which vinyl chloride resin is adopted, is lighter in weight and easier to carry out than the conventional series. Therefore, a trial can be carried out with little efforts or installation burden.
● Immediately testable
You can make a trial immediately because the structure is simple compared with conventional water circulation systems. Since the pump is simply submerged in the water tank or pit under the cooling tower, new water piping work is not needed. Since the power required for trial “WET” is 100V AC, a general outlet can be used.

Example of trial use
An example of customers’ trial use is given below.
| User | Factory so-and-so in Mie |
|---|---|
| Purpose | It is desired to prevent troubles by scale in cooling towers and piping by removing scale components from cooling water supplied to respective cooling facilities in the factory building. |
| Target cooling tower spec | Open type cooling tower, 100 tons of cooling x 2 (standard quantity of circulating water: 1300L/min. x 2) |
| Outline of installation flow |  |
| Customer evaluation | By about one month of use, a large amount of scale was precipitated in the tank of “WET” and the water quality was improved. |
