EMP Engineering Services offers infrared thermography inspection services to clients for a wide range of applications.  Infrared thermography allows the user to 'see' heat by converting infrared radiation into visible light.  This heat can reveal abnormalities ranging from loose electrical connections to clogged cooling tubes to trapped moisture and failed insulation.


Key Benefits of Infrared Inspections

  • Cost reduction through the early detection of problems such as bad connections and blown coils.

  • Improved efficiency through the identification of wet insulation or cracked refractory.

  • Reduced downtime through increased equipment reliability and availability.


EMP Infrared Inspection Capabilities

EMP Engineering Services uses a Flir P25 thermal imaging system to inspect and document thermal conditions.  This instrument is complemented with ThermaCam Reporter 8.0© processing software.  This software integrates with Microsoft Word© and allows us to prepare detailed reports including isotherms, average temperatures and thermal histograms.  The Flir P25 can also record data to a DVD so that time-varying phenomena can be observed and recorded for viewing on a television.


Electrical transmission and Distribution Inspections

Faults in transmission and distribution lines and equipment usually have symptoms that result in temperature changes long before they fail.  A loose or corroded connection will warm up as contact surface area goes down and arcing goes up.  Turn-to-turn shorts in coils result in localized heating.  Bound contacts cause their operating coils to overheat due to excessive current draw.  These are a few examples of the types of problems that can be found in transmission and distribution lines before they cause a failure.  EMP has inspected transmission and distribution systems from 132 KV on down.  We also have substantial experience with DC systems including low voltage, high current operations such as platers.


Problems are reported using thermographs and photographs, with a location, problem description and recommendation included.  A summary of problems is then provided to the customer by hard-copy or delivered via the internet in a pdf format or both.


Furnace and Refractory Inspections

Industrial furnaces usually have insulation systems such as kaowool or refractory block insulation to reduce heat loss.  Damage to these systems can lead to excessive heat loss and thousands of BTUs and dollars being wasted.  Such damage is easily identified by infrared inspections.  Periodic inspections and trending of results provide valuable information to make timely decisions about when to shut down a process for maintenance.  EMP inspects furnaces for many clients on a regular basis.  We establish regular inspection points and use the same perspective and temperature readings so that damage can be readily identified when it happens.  We also understand how difficult it can be to look at hundreds of images so we use wide angle lenses to see the whole picture and minimize the number of shots to be inspected.


Roofing and Building Envelope Inspections

Built-up roofs will trap moisture either in the insulation or on top of the decking.  An infrared inspection of the roof will provide an extremely cost-effective means of identifying such moisture without expensive and damaging core sampling.  EMP has extensive experience with built-up roofs in industrial, commercial and office building applications.

We can also perform building enclosure inspections to confirm the status of insulation and to find holes and cracks that allow heat to pass through walls and barriers.  As with all of our infrared services, results are documented (including photographs and thermographs) and provided to the customer.  This allows building services providers to quickly and easily identify problem areas and address them with the appropriate party.
