First I would get rid of the passive system you are using and move to a active system. This will serve several needs. One, it will be more consistant. Two, the better active systems have built in fans to circulate the air.
Second, here is the name of two very good companies who will sell you a system to fit your needs. The first is Vigilant, Inc (www.vigilantinc.com). They have several systems that they sell, and can help with cabinet conversion if you purchase you humidifier from them. Ask for Mr. Steve Huntoon at 1-888-812-4427. Another company you can contact is CMT, Inc. They are on the web, but I am not sure of the site name. They provide the systems to many of the better cabinet makers. Their selection is very diverse. The number is 1-800-659-9140.
Both of these companies will promtly send out info. Good luck! Berry
