I'm trying to put one in, but boy oh boy are they expensive!
-
we built one it is basically a plywopod box that holds a number of screens. In the bottom we built in a $12.00 heater from lowes and a $7.00 t-stat.
The heater has a fan, the t-stat keeps the inside at @ 90 degrees. Will dry a hose spaked screen in about 20 minutes a coated scen in about one hour.

yes.
http://www.vastex.com/Articles/Screen-Drying.php (http://www.vastex.com/Articles/Screen-Drying.php) good stuff, helped our pre-game logic
(we actually retired a vastex drying cabinet in place of this - the roll in/out is a huge time saver - worked great otherwise. anyone want to buy it from us?)
this is IN our dark room, which is sealed, and humidity/temp controlled, and MOSTLY dust free.
1 box. 1 door. 1 wall is exit vent, opposite wall is intake vent. intake vent is a box with a fan on top, connected to a egg timer.
sized to fit 1 alloy america screen rack, rolls right in and out.
dehumdifier on top has nothing to do with it, just a convenient place to put it.
we put degreased screens in to dry.
we put emulsioned screens in to dry.
downside, it DOES raise the screen room/dark room humidity up from 30% to about 40% for about an hour before the dehumidifier can catch up.
a heating element WOULD speed the dry times, but that time ain't squeezing anything so we just sit it out.
we thought about outside air (to not humidify the room) or to make the cabinet not IN the screen room (same), but you would need a decent dust filter AND to worry about light - not worth it in our case.
we don't need to filter the air. MINIMAL pinholes.
you'll want some heat to help speed the dry if you want more than 15 screens dry in less than an hour as a rough rule of thumb.
