I'm looking for suggestions of a humidification system for my shop. It's 5600 sq.ft in PA. On cold days when they gas heat runs all day the humidity level can drop to around 20% which is causing cupping and splitting of our wood.
I think my shop is probably a little too big for portable household units, but maybe not big enough for an industrial system.
Thanks for your help!
My shop is only 2400 sf but the ceiling is about 30' at the peak which doesn't help. I bought the largest Sears model which puts out 4+ gallons a day and it still falls short of what I need. So I'd say your right that these won't work for you unless you buy multiple units.
I have been using a couple of Bahnson Type E humidifiers from DnB HumidifierMfg. in 6000 sq. ft. for about six years now. They have been working quite well since then.
About the only thing they require is to be cleaned out a couple times a year. They hang from the ceiling so dust settles in them.
A 1/4" water line is plumbed to them so they fill themselves as needed. I found out about them at the Vegas or Atlanta show.
Thanks for the suggestions. I might try 2 of the Home Depot units to start with and maybe I'll get a season out of them. The type E Gary suggested would be perfect, but they are $1500 each.
Rich, which unit did you purchase from grainger? This is something I've been struggling with for years.
Any chance you can share a picture of your setup? I think id like to give that a try
At 70F, the amount of moisture required to increase the humidity from 20% RH to 38% RH is around 1 pint per 3000 cubic feet of air. Of course, air leaks to the outside or dust systems that vent to the outside will greatly increase this.
You do not want to go above 38% RH, as this will be much more humid that a customer's home or office, so the wood will shrink when the customer gets it...high humidity just pushes the problem to the customer.
Also, note that dry wood is quire strong, so observed cracking is often a small unnoticed crack that grows rather than creation of new cracks.
