Hi, If you need to get a humidity target, the best way is to run the air conditioning plant very cold, which will drop the moisture out of the air, and then you can reheat to the required temp, and install humidifiers to re humidify the air to the r

Not sure what kind of humidifier you are looking at but here's my experience: We have 4 humidifiers. All are ultrasonic supplied with DI water. They work well but... UT humidifiers will create a foggy white residue that will stick to things in cl

I've never run D.I. water through an ultrasonic humidifier before. I think the reverse osmosis (RO) process removes more stuff (minerals and etc.) than the D.I. process does. My experience from using one in a home setting still tells me that is the

Check your humidity levels there as well. If the airs to dry it would dry out your paste as well. We had to go out and buy some floor humidifiers for our place.

We run humidifiers in our shop because we are usually around 25% RH. We track this with a data-logger and RH device. It's dry here! Sometimes in the summer, it can get between 5 and 10% RH outside = thunderstorms/dry lightning and forest fires. I

By no means clean room but pretty clean environment. We have ultrasonic air humidifiers maintaining our air at about 45 RH. I agree with you about airborne stuff attaching to electro-static. It's a mystery why it is isolated to four machine, thoug

We have four or five of these guys scattered around our 40,000sqft plant spraying DI water. They have a not so accurate built in humidistat but its good enough and they aren't that expensive for upfront cost. Just lube the packing washers in the gun

Hi, I ran a clean room once, and the humidifiers were built into the exit air ducts, and controlled by a humidity control unit that kept things at 60%. We were loading VHS tapes, and needed to keep humidity at that level or static discharges caused

Hello Because of the cold weather, we had some troubles with drying out of printed solder paste on the pcb's. The relative humidity in the air declined below of 20%. We have a process window of store the printed board for maximum 24 hours, but with
