Rinnai Corporation, the largest manufacturer in the world of gas appliances and tankless water heaters, set out through Rinnai America Corporation to find a solution to hard water scale deposits in their tankless water heaters. Salt water softeners helped but were not the answer because they only reduced scale buildup but did not eliminate it. Thanks to FREIJE Treatment Systems, a total solution was found.   

Rinnai conducted field tests with FREIJE Descaling Technology on actual tankless water heaters operating at 150°F to 185°F in San Angelo, TX (which has some of the hardest water in the United States). These sites in San Angelo were chosen because of their history with heat exchanger failures due to hard water scale deposits.

At the conclusion of the test, all of the test heaters were inspected and were found to be free from scale deposits. The photo to the right shows a heat exchanger tube cut long ways from the 185°F test heater. This was the most scale prone of the test sites since it was at the highest temperature, but at the end of the test absolutely no scale deposits had formed. In the past, this same heater had been inoperable due to scale deposits after a fraction of the test period. This was the final proof needed for Rinnai to recommend FREIJE EasyWater Systems for residential applications and FREIJE Series E Treatment Systems for commercial applications to eliminate scale deposits.  

Unlike any other product on the market, Rinnai found that the FREIJE Systems can eliminate scale buildup in tankless water heaters and will even remove existing buildup in most water scenarios.
