Voodoo Stick?
Voodoo Stick?
(OP)
Is anyone familiar with Fluid Dynamics (www.fluiddynamicsna.com) products? We are considering a "Scaletron" to serve an industrial heat exchanger (less than 10 gpm continuous use). They boast that the product is effective for 25 years, but they have only been selling in the US for 2.5 years. Sounds like a great product (no electricity, chemicals, or maintenance), but is it too good to be true?

From the Fluid Dynamics Website:
"How does Scaletron work?
Water is passed in a turbulent state over a special metal alloy which alters the composition of the water near the alloy surface. This action changes the supersaturation ratio of the water and ensures that lime does not form hard lime scale"
Aha...! Its the "special metal alloy" that does it !
That's the same alloy used with the perpetual motion machines, 600 mpg spark plugs and the 30 day Viagra pills (all available over the internet !)

Basically, I am conflicted because of the amount of published papers that state this technology doesn't work however I personally have seen lots evidence of it working. On that note, we have tested out electrical magnetic water treatment options (as opposed to permanent magnets) and found that there was no measurable scale reduction. Additionally, we have seen that some hard scale does form in the magnetic tube and that needs to be cleaned out 1-2/year. How critical is your application? Can you risk experimentation or failure?
