A blood system is one of important for our human body. What a blood vessel is carrying a blood as what a valve is carrying water. If a blood vessel got clogged by foreign bodies, human got disease by such a small matter.  

As like that, such a same matter will be happened at pipe and water system. The matter of rust & scale is looks like small problem but it will cause all kind of potential and serious problem. It is not only economic loss by decreasing efficiency but also environment pollution by using chemical.

Now we realized that we need alternative technology instead of chemical. Depends on customer's demand, we bring PTH into market. It is outstanding device for preventing rust and scale. We are sure its device will solve both problem- Economical and Environmental.
