Eddy Current Testing
Trane recommends conducting an eddy current
inspection of the condenser and evaporator tubes in
water-cooled chillers every three years. Eddy current
tests are intended to identify defects on or within the
walls of heat exchanger tubing that could lead to in-
service tube failures. Eddy current tests conducted
before a chiller is put into service are considered
“baseline” eddy current tests, and are intended to
establish a reference point to aid in the interpretation of
future eddy current test reports. Many of the anomalies
that can be found through eddy current testing have no
impact on tube life or performance, while others are
severe enough to justify removing the affected tube
from service. Ask your sales account manager for a
copy of the engineering bulletin (CTV-PRB024*-EN) for
clarification of the role of eddy current testing in chiller
maintenance by providing information about eddy
current technology and heat exchanger tubing.
