摘要： A degassifying apparatus for removing air or other dissolved gas from liquid comprises a degassifying tank placed under at least a partial vacuum. The apparatus also includes a coiled tube having a plurality of turns in a generally spiral configuration which is positioned within the tank. Spacer elements are positioned between adjacent coiled turns of the tube and/or between the tube and an inner wall of the tank to eliminate contact between the tube and the tank and to thereby maximize the total surface area of the tube which is exposed to the decompressed atmosphere within the tank. This provides a highly desirable and advantageous degassifying effect to the liquid being conducted through the tube.
