We have a very small cleanroom. We don’t control the humidity or temp in it. I feel like it is really dry and warm in there.

Is there any inexpensive ways to resolve how dry it is in there? We are planning to fix the heat problem but I don’t really know how to aproach the humidity without it costing a fortune.

Humidity Control can get expensive that is for sure. There are several ways to add humidity to the facility, but needs to be weighed with you existing air handling equipment. You are welcome to send us your layouts and particular requested to designbuild@digitalaircontrol.com

Thanks!
