How can infrared thermography impact your bottom
line?

• Evaluate equipment reliably, efficiently, and
  without disruption to operations.
• Ensure uninterrupted power.
• Avoid costly failures and shutdowns.
• Postpone previously scheduled maintenance of
  equipment found to be in good condition.
• Verify new equipment installations to establish a
  baseline for future inspections.

How can infrared thermography impact your bottom
line?
In many cases, the savings in insurance claims
due to predicted equipment failure have pushed
insurance companies to obligate their clients to
perform regular infrared inspections as a term of
their policy renewal. Many studies have shown
that the financial and safety benefits to
industrial and commercial facilities far outweigh
the costs of implementing and maintaining an
effective PdM program.

What is Infrared Thermography?
What is Infrared Thermography?
Heat is referred to as the transfer of
electromagnetic energy, in the infrared band,
through either conduction, convection, or
radiation between two or more substances. The
measurement of the transfer of this infrared
energy is called temperature. There is no heat
or temperature without this energy transfer.
Infrared energy is invisible to the human eye but
can be felt , sensed, and measured.
5
What is Infrared Thermography?
The infrared camera evaluates and converts heat
energy into meaningful temperatures. Components
in various states of failure will emit more heat
as a direct result of more energy dissipated into
the component. This extra energy is caused by
increased friction in mechanical devices, and
higher resistance in electrical devices.

Why use infrared thermography?
Why Use Infrared Thermography?

• Just as doctors use temperature in disease
  diagnosis, infrared thermography allows us to
  diagnose and pinpoint problems based on the
  temperature differential of areas. Temperature
  provides an excellent indication of the condition
  of equipment.
• It is the ability of the thermal camera to "see"
  these early stages of increasing temperature that
  makes thermography such a valuable technology.

Why use Delmarva Infrared Services?

• We use a state-of-the-art database and barcode
  system which allows accurate equipment tracking
  and maintenance records as well as a tool for PdM
  scheduling and maintenance priorities.
• Field experience with not only the infrared
  equipment, but also hands on experience with
  electrical, HVAC and industrial equipment,
  allowing not only the discovery of problems, but
  accurate interpretation of exact problems, so
  they can be corrected quickly and efficiently.

What kind of equipment will be used to perform
the inspection?

• Delmarva Infrared Services uses an extremely
  lightweight, high-performance, hand-held Fluke
  FLIR infrared cameras.

10
What kind of problems can Infrared Thermography
detect?

• Infrared Thermography has been proven to find,
• quantify, and document problems caused by
• Electrical Mechanical
  Building
• Faulty components Shaft misalignment
  Moisture infiltration
  of roof
• Poor connections Worn bushings
  bearings Air infiltration or
  exfiltration
• Corrosion Improper
  tension of belts pulleys Areas of
  potential mold growth
• Contamination Over or under
  lubrication Air circulation
  and distribution
• Load imbalances Gear box anomalies
  Leaky or clogged
  pipes
• and much more Excess friction
  and much more

Electrical Inspections
The anomaly, or hot spot, indicates a probable
problem with the disconnect.
12
Electrical Inspections
Poor connection to common buss bar in circuit
breaker panel.
13
Electrical Inspections
Poor fuse to fuse clip connection.
14
Electrical Inspections
Probable loose or corroded connections.

21
What information will be provided after the
inspection is complete?

• You will receive an easy-to-understand report
  that provides thermographic images, digital
  images, and temperature information to help you
  determine what needs corrective action and what
  is operating normally.
• The written report will include an inventory of
  all anomalies, and follow-up documentation of
  past problems. This information is presented in a
  logical order so that your engineer can formulate
  an effective repair plan.
