Thermal Techniques provides infrared inspection services to identify electrical, mechanical, and roofing issues before they cause equipment failure or downtime. Their inspections have found problems like loose fuse clips approaching 300 degrees, a faulty disconnect that could have caused a $9,000 compressor failure, and moisture trapped beneath a flat roof. These inspections have helped clients avoid downtime, emergency repairs, and costs estimated from $2,000 to $25,000 by identifying issues for scheduled maintenance.

With an Infrared Program
To whom it may concern,
With this Information Packet you will find “sample images” showing the power
and diversity of the problem finding ability of our services. These images are just
a small sample of the thousands of problems we find each year. Infrared
inspections are an extremely powerful tool that can increase the life, and health
of electrical systems and mechanical equipment.
The use of state-of-the-art equipment and our experience allows us to find an
average of 15 problems per day. We like to refer to these problems as
opportunities for improvement. A timely repair of just one of these problems
usually, more than justifies the total cost of the inspection.
Our inspection service prides itself with performing an extremely thorough and
professional investigation of your equipment. We look forward to the opportunity
of working with you and your staff. Thank you for taking the time in letting us
show you the Power of Infrared.

An infrared survey can pay for itself and avoid downtime
Objective: Illustrate the predictive maintenance benefit of and infrared survey
to find hot spots before they become trouble spots
An infrared survey found this newly installed disconnect switch feeding a critical
air compressor. Customer estimates failure of this disconnect would have cost
more than $9,000.00 in lost production. This was one of thirty items revealed by
the thermal imaging engineer.

The photo on the left might just be the most important electrical cabinet in your plant. Visually it appears to be quite
normal, clean and in good condition. The photo on the right however is of the same fuses only as seen through the
Thermal Techniques infrared imaging camera, which reveals that some of the fuse clips are in excess of 200°F. We
refer to this as an opportunity for improvement that can save you unexpected losses and interruption of production.
Our infrared inspection service of your facility will allow you to find the problems that you have before they find you.
Timely repair can be implemented and your facility and process will run as expected. Direct benefit will show up as
increases in production, less downtime and fewer emergency repair situations for you and your staff.

4. Critical Equipment Test Results
(Another example of the power of thermal imaging from Thermal Techniques)
Main breaker for a PDU (Power Distribution Unit) had unexpectedly tripped.
Thermal Techniques was called in to help evaluate the cause. The infrared camera
revealed that the bottom left connection on the main breaker was excessively hot.
Close examination revealed that the factory lug was several turns from being
properly tightened. The poor contact at the connection caused heating and the
breaker to trip.

The photo on the left shows some very important vaccuum fan as most people see them. The image
on the right is how we see them and one of the bearing is excessively hot (175°F). Without this
vaccum system running the process is not able to run and no production of product occurrs. Thermal
imaging can keep you plant running by finding unexpected failures before they find you. By using
thermal imaging downtime can be avoided and repairs can be made in a timely manner. Loss of
production is avoided and emergency repairs are minimized for you and your staff.

Infrared Inspections for Flat Roof Systems
You see this
We see this
Thermal imaging is a proven technology for finding moisture problems
in flat roofing systems. Given the extremely high cost of replacing
your roof system, an infrared survey can be a valuable tool for finding
the areas of your roof that are damaged and in need of repair.
In a flat roof system, during a sunny day the roof will heat up at a fairly
uniform temperature. At night, the areas of the roof that have
moisture trapped beneath will retain their heat for a longer period of
time. An experienced thermographer can find, analyze and mark of
areas that need repair. Timely repair of these areas can save your
roof from any further damage.
If you have any questions, or need further assistance, please
give us a call at 704-343-0888.

Cost and Savings
With an Infrared Program
Note: The following is privileged and proprietary data as well as copyrighted.
Any duplication or reproduction without prior written consent is not permitted.
BEARINGS:
This bearing is much warmer than
the motor (on right of image). Note
that the bearing guard did not have
to be removed for quick and easy
access by the thermal imaging team.
If this had gone undetected this
bearing would have ultimately failed.
Failure would result in process
interruption and force the emergency
repair team into action. Failure could
also cause shaft and fan damage,
and necessitate new equipment
having to be shipped in at a higher
cost for a replacement unit. Thermal
imaging allowed scheduled
downtime and easy repair to avoid catastrophic failure and dollar savings estimated at
$3000.00.
POWER LINE TO PLANT
This image shows a power pole and a main
transmission line to a plant site. The plant
had experienced several voltage dips
causing running equipment to loose power
and shut down. The computer center at the
site was affected the most as documents
and data were lost during the voltage sags.
Power company officials advised the loss of
power was not on the grid and was probably
inside the plant. Thermal imaging was
employed on all transmissions lines to the
site back to the substation serving the plant.
This was a splice joint that had been
installed due to downed lines from an ice
storm several years earlier. The Thermal
Imager was successfully used to locate the faulty wire splice. Power company officials
worked with the plant site staff to have a controlled outage so that the repair could be

8. made. At least 4 hours of plant shut down was avoided and cost savings were
estimated to be in excess of $25,000.00
CONTACTOR – MOTOR STARTER:
Motor contactors-motor starters are
subjected to high in rush amps and it
is critical that infrared inspections are
used to find the numerous problems
that can be found on these items.
The above image clearly shows a
faulty/loose connection at the bottom
right lug connection. This contactor
is used in an injection molding
machine and the cost of down time is
estimated at over $800.00 per hour.
Undetected failure could result in a
loss of production in excess of 2
hours. In this instance thermal
imaging informed plant personnel
that the wire on the right phase was probably damaged since the temperature exceeded
210F. In this manner a new wire was pulled from the motor to the contactor, and the
offending wire was removed. All of this was scheduled during a mold change so no loss
of production resulted. By replacing the wire, thermal imaging was able to assist in
complete corrective action the first time as opposed to patching the problem during a
production period and having to do additional repairs at a later date. Early detection
also is credited with saving the contactor-starter from future damage. Estimated savings
were $2500.00.
FUSES
Quick and early detection of an
electrical fault, such as this fuse clip,
can help prevent overloading or a
potential unbalance in a 3-phase load.
This fuse, located in an oven control
panel, controlled one of the heating
sections within the oven. The curing
process is one of time and temperature. If the heat is not correct for the
proper time duration the quality of the
product is adversely affected. This
results in product rejects and
production losses. Faulty fuse clips
can cause early and premature fuse
failure. Without the use of thermal
imaging, Maintenance Personnel end
up replacing the fuse on a continuing basis and never suspect that the root cause of the
continued failure is the fuse clip and not the fuse or some other item in the electric
circuit.
