Hi Joyce,

Remember when I was working in Allentown? We had really bad low humidity
problems during the winter, our spaces were heated by a gas burner
warehouse heater, the thing sounded like a jet aircraft when it turned on.
Humidity would drop like a rock. We put together a humidity control fogging
system that was put together with a control and monitoring system from a
company called Fogco ( https://fogco.com/ ). We had a 20,000-sq. ft. area,
so we had 3-misting fans that kept the humidty right where we needed it.
You might give these guys a call and tell them the specifics of what you're
dealing with (area, humidty range you want to see, etc.) and I'm sure they
can help you out.

Steve
