Maintain heat exchangers in optimum condition
- Identify conditions of any tubes exchanger
- Eddy Current tube testing
- Report nature of defects
- Identify cause of failure
- Comprehensive report with recommendations for corrective actions
Detect faults early and increase system reliability
A heat exchanger contains several hundred tubes, all undergoing mechanical stress and chemical corrosion. Tube condition is critical to chiller performance but is not checked during standard maintenance. Equipped with the latest technological tools, Trane can detect, locate and record internal and external corrosion, deposits, wear or cracking before any major compressor damage results.
Eddy current tube analysis is the recommended scientific method to identify the root cause of an exchanger problem and the extent of tube damage. While relatively easy to maintain, heat exchangers can be very expensive to repair or replace. To avoid this, tube analysis should be conducted as a part of predictive and curative maintenance. Trane tube testing is applicable to all types of tube in shell heat exchangers.
Analysis of evaporator and condenser tubes by Trane service experts
Trane has over 30 years of tube testing experience and was in fact the first HVAC manufacturer to apply the Eddy Current technique. Trane specialists use an inspection probe inside each tube of the exchanger unit to detect the magnetic field that is generated by the eddy currents. The magnetic field is monitored with a micro-processor-based memory oscilloscope. If a defect such as a crack is detected in the tube, the magnetic field from the eddy currents will be disturbed from their normal circular shapes and a change in the signal will display on screen.
