ABSTRACT:
There is disclosed an improved dearator system for purging air from water. The disclosed system includes a container for containing the water, cooling means within the container for cooling the water to force air therefrom, and means for introducing carbon dioxide gas into the container to establish a positive pressure therein. The system also includes a positive pressure indicator means for indicating when the positive pressure within the container is reached. The indicator includes a housing having a bore in fluid communication with the container, a seat within the bore, and a ball within the bore. The ball is viewable through the housing and is arranged to disengage from the seat in response to positive pressure within the container to provide a readily discernible indication of positive pressure therein. The system also includes a check valve functionally interposed between the container and the positive pressure indicator for intercepting liquid travelling towards the indicator housing to thereby inhibit damage to the housing.
