Abstract The system removes gases and moisture from dielectric fluids such as, for example, insulating oils normally used to provide electrical insulation between electrical components in a tank filled with such dielectric fluid. Degassing occurs in a treatment reservoir into which the fluid is initially introduced and such degassing is accomplished using a combination of vacuum and ultrasonic vibration and also, in some instances, the fluid may be heated in the reservoir to a sufficiently high temperature to assure efficient liberation of moisture from the fluids. Special valving and connections between the treatment reservoir, the aforementioned tank and a supply container provides versatility and transfer of fluids under optimum conditions. For example, the fluid may be first introduced into the treatment reservoir from a supply container and then after treatment in the reservoir be transferred to the tank wherein the same serves as an insulating medium for electronic equipment; alternatively the fluid already in the tank may be treated by causing the same to enter the treatment reservoir for treatment after which the fluid is returned to such tank.
Apparatus as set forth in claim 1 including a third conduit-connecting means for connection to a supply container, additional valve means the last mentioned valve means having one of its sides connected to said third conduit-connecting means and the other of its sides in communication with said means communicating said second conduit-connecting means with the bottom of said chamber.
