On August 15, 1997, American Certified Laboratories, of Wilmington Delaware began a three-month trial test of the PowerMAX. The device was installed on a ¾" water supply pipe that fed a 50 gallon laboratory hot water heater.

"The PowerMAX, when installed per the manufactures instructions did perform well over the test period. It performed its main function of removing and preventing limescale in a very effective manor." "Surface tension and zeta potential differences through testing suggest that the claim of savings up to 80%* on chlorine usage can be substantiated."

* Results may vary in different parts of the world, due to the quality of the original water supply.
