【Application】
ESR provides a method to prevent scaling troubles caused by the use of water and heat generation equipment such as hot and cold water facilities, boilers, cooling towers, heat exchangers, piping etc, and to prevent the occurrence of rust. It also suppresses the decline the heat exchange　efficiency in the heat exchanger.

【Principle】
By effectively applying energy to promote dissolution of scale caused by minerals (calcium, magnesium, iron, silicon, etc.) contained in makeup water, scale removal and generation of scales in piping are suppressed . In addition, the passive coating over the surface of iron (black rust) is formed to prevent rust.
【Device configuration】
The configuration consists of a controller and an electromagnetic field generation part, and is connected by a signal cable. The electromagnetic field generating part is made up of a pair of semicircular shapes and is installed by sandwiching piping. We prepare things according to pipe diameter.

【Effect confirmation】
Based on the results of scale analysis and water quality analysis, after installing the ESR whose frequency is adjusted, we will follow up the effect for 3 months every month and verify the effect. We routinely submit the results to customers.
