Overhumidification on Coolidors

[drew_goring]

Actually, a drop in temperature will increase RH in a sealed unit such as a cooler. That's when you need the beads to absorb. You should put your cooler in a location with minimum temperature fluctuations as your RH changes with temperature change. Hotter = lower RH, cooler = higher RH as long as the water volume in the air remains constant.

Yeah, I wasn't very clear with that. What I was getting at is that generally in a hotter climate, ambient humidity is much higher as opposed to the nearly 0% humidity we experience in the winter, which makes our humidification devices have to work just that much harder. If you just have a sponge with water in a climate with a high ambient humidity there is definitely a risk of over humidification. This makes the beads a very attractive choice because as long as you use them right, they can absorb and release water.

But yes Mark, you are right-in a closed system.
