A steam bath...
precisely! The Filtrator dryer is, but for less than a dozen 1/4" holes in the cabinet, a closed system so with the higher operating temps, the water is quite literally "boiled" out of the fabrics being dried. The Filtrator does a great job getting the water to evaporate into steam, but it is rather slow to remove the moisture from the dryer. The air-cooled aluminum tube system at the bottom of the drum creates a natural convection for the heated, moist air. As the moist air is drawn down to the cool tubes, the moisture condenses in the tubes and drips into the water tray directly below the tube-unit. It's important to maintain the Filtrator dryer as a heavy coating of lint inside the cabinet holds moisture and slows the already-a-little-slow convection process. After about 15 minutes on high-temp, don't stand over the opening door or you could get a painful red face from the steam that pours out. This is my all-time favorite towel drying method, that steamy drying seems to revitalize towels and most cottons into their most puffy-softness. Very little or no fabric softener is even required with this moist drying climate, I don't think I've ever noticed any static electricity.
