Music Sorb product

[Farrell]

Experience? No. INFORMED opinion? Well, biased.

I rode from the hotel in Dallas to the Airport with the guy from that company. He told me a bit about it on the way. Most any silica gel thingee I have ever seen simply has an ability to absorb water from the air. Once saturated with water, it then needs to be thermally desorbed. The difference with this gizzmo is that it has a RH level at witch it will be in equilibrium with the surrounding atmosphere (don't remember if this was 42% - but some piano-friendly RH), i.e. it will neither absorb nor desorb water. If the RH in the surrounding atmosphere rises, the unit absorbs water, and thus lowering atmospheric RH. When the RH drops below the equilibrium RH, the unit will desorb the water and raise atmospheric RH.

Now what happens when you have 80% RH in the room, an air exchange between the piano interior and the room air - I suspect that at some point the bag of stuff would get saturated - maybe you can just ring it out? Sounded like it had some potential.

Let us know what you might find out.
