Note under the picture of the machine the text states that it has safe one temp drying at 160F. 160F is the temperature at which Wash 'n Wear fabrics whether blends or treated cotton shed their wrinkles. This is the temperature to which the load is raised in a Maytag electronic dry control HOH dryer if you select the Wash'n Wear or Permanent Press cycle. After the control senses dryness in this cycle, it continues heating to raise the temperature for best Perma Pressed results. This additional heat is also why the cycle was recommended if extra drying was desired. From the first model, the Bendix Duomatic dried at this safe temperature. I was surprised that even with warm water rinses & the 500RPM spin, Permanent Press came out of my 1954 Duomatic looking just as good as from a newer machine. The Duomatic is timeless, a machine for all ages and fabrics.
