Abstract: A tank assembly including an upright tank, a lid, a temperature control system, and an actuator assembly. The tank includes a closed bottom end, an open top end, a tank sidewall extending between the bottom and top ends and defining a tank interior having an interior surface, and an elliptical cross-sectional shape. The lid is positionable to seal closed the tank interior. The temperature control system may be operable to control a temperature of a substance retained within the tank interior. The lid may have a peripheral surface that is configured to seal with the interior surface of the tank. The lid may also have an elliptical shape.
