Abstract: A condenser purge probe is provided for use with a condenser enclosing a plurality of condenser tubes, wherein the purge probe has a wave-like form comprising a plurality of alternating wave segments having exterior configurations approximating portions of the exterior configurations of the condenser tubes. The purge probe is selectively positionable in conforming and interlocking relationship with selected ones of the condenser tubes, thereby permitting selective placement of the purge probe in the condenser and substantially reducing vibration of the probe during operation of the condenser.
