1. An apparatus for degassing a liquid, the apparatus comprising: a container for the liquid, the container including an inlet and an outlet for the liquid, the outlet being positioned above the inlet; an ultrasonic transducer; and a radiator coupled to the ultrasonic transducer such that activation of the ultrasonic transducer creates ultrasonic vibration in the radiator, wherein the radiator has a hollow shell defining a fluid flow path for transporting a purge gas, the shell including at least one throughhole that extends from the fluid flow path to a top surface of the radiator, and wherein the radiator is positioned in a wall of the container such that the top surface of the radiator can contact liquid in the container, the top surface of the radiator being flush with an inner surface of the wall of the container, and wherein the liquid flows above the top surface of the radiator upward from the inlet to the outlet.
