Eddy Current Testing
Eddy current testing is a non-destructive electromagnetic method used to inspect the integrity of condenser and evaporator tubes in centrifugal chillers. An electronic probe is inserted into each tube and generates an electromagnetic field. Changes in the field response indicate tube wall thinning, pitting, cracks, or other defects that could lead to leaks or refrigerant-water cross-contamination. This testing is typically performed during off-season maintenance when the chiller barrel is opened for inspection.
Eddy current testing: an electronic probe detects tube wall thinning, pitting, and cracks by measuring changes in electromagnetic fields.
