A tight-fitting lid is completely removed from the main body. The water bath capacity of each unit is 3 gallons (the original) and 2.3 gallons (Demi). The maximum temperature is 210 degrees F. Double wall insulation makes it energy efficient, and the exterior is cool to touch. Thanks to a perforated grill on the bottom, foods don’t touch a heated surface directly. The perforated grill lets heat through. Both models rely on convection to circulate water. So, there is no motor. It allows it operate silently and makes it more energy-efficient.
