What is Eddy Current Testing?
testing is a nondestructive accurate method of analyzing your air
conditioning and heat exchanger tubes. It can be done quickly with
minimal downtime. This type of testing will identify common problems,
which cause tube leaks that result in major repair cost and extended downtime.
How often should Eddy
Current Testing be done?
testing is recommended on all tube bundles at least every (3) three
years. Eddy Current test results can be compared to the prior test to
help determine rates of tube deterioration as well as predict future
tube life. In some cases where well water is being used or there is
no water treatment, then yearly Eddy Current testing is recommended.
How much does Eddy Current
factors determine the cost of an Eddy Current Test such as the type
of machine, the quantity of tubes, the driving distance, etc. Please
contact Eddy Current Analysis with your make, model, and serial
number and the location of your chiller and we will be happy to send
you a bid.
Does Experience Matter?
Analysis technicians has been trained and certified in accordance to
guidelines established by the American Society of non-destructive
testing. It is very important that the technician performing the ECT
(Eddy Current Test) understands the various types of machines and
tubing as well as the proper techniques in performing an ECT. Eddy
Current Analysis will provide a certified Level III technician as per
How should I prepare my
chiller for Eddy Current Testing?
1) Remove the
head from the 'easy end' (the easy end is the head without the piping).
2) Place the
head away from the test end, normally along the side of the machine.
brush the tubes with a good tube-brushing machine. I recommend the
Goodway Model RAM-4 or the RAM-6.
How important is Water Treatment?
are many things that could cause damage to the condenser tubes such
as vibration, debris, or stress; the single most common problem that
we encounter is improper water treatment. We know after completing
our test whether or not your water treatment program should be reviewed.
