I produced HVAC CS for about 6 years before switching to LVDC. With my setup I was unable to exceed more than about 7 to 8 ppm before the particles stated becoming objectionably large, and even at 5 it produced a yellow instead of a clear EIS. It was a real hassle, requiring a 1 1/2 ton cooling unit to keep the EIS cool enough to prevent even larger particles.

I use high voltage DC, not AC.  And only to kick start the process.  I very
 quickly reduce the voltage as the silver ions start building up, to limit
 the current.

Hello Dick,

It seems that this is an area that has been looked at before and there are
some theories on the quality of EIS produced at high voltages.
Unfortunately, extensive testing is cost prohibitive, so you will just
 have
to go with the theory.
I think I recall that ole Bob spent quite a bit of time experimenting with
 HVAC, and eventually stopped. Now that there are archives again, there may be
 some info there.
Anybody else remember this, or am I confused again?
