The IW Series is manufactured from industrial grade materials designed to withstand electrical arcs and certified by Underwritten Laboratories (UL) to follow the very latest IR window standards. Install the certified, IW Series SMART IR Windows to help comply with NFPA70E electrical safety guidelines and reduce the need to wear large and bulky PPE.

Take a look before you shoot with the high security, spring loaded impact cover. With IW Series, there is no need for second visual inspection windows in addition to your IR Windows, as you can confirm switch positions for lock-out tag-out compliance with the same Window as you shoot IR. Maximise your investment, don’t throw away your IR Windows when you change your equipment. The fully removable IW Series IR Windows can be used again and again, outliving the life of your equipment.

Through intelligent design and special features, the IW Series reduces the time it takes to perform inspections. With the 1/4 turn locking system and spring loaded cover it reduces your time per inspection.

The IW Series crystal lens is also protected with HYDROGARD™ advanced formula to stop environmental moisture damage allowing the windows to be used both indoor and outdoor.

Are the IR Windows lenses water soluble?

The crystal lens material is not water soluble.

However, the IW Series has a HydroGARD protective coating to help protect them from all elements. The IW Series Windows all have an IP65 rating.

Can your IW Series Windows be used with any IR camera?

YES. The IW Series Windows are designed to be used with ALL IR CAMERA’S. The only consideration is what operating environments and equipment should be used when making your inspections.

How long is the warranty on your IR windows?

The IW Series Intelligent IR Windows are guaranteed against any manufacturing defects and for the life of the panel in which they are fitted, they are not guaranteed against damage or misuse.

Is it important to have a high transmission rate?

It is imperative to understand your IR transmission rates and wavelengths that your IR window works in. The transmission of your IR window is needed to accurately calculate your temperature correction. The IW Series Intelligent IR Windows are all individually tested in a transmission correction chamber to calculate their individual transmission rates. Using RoutePLANNIR™ or the IW Series Installation App it is possible to get these readings on site.

Is the IW Series Intelligent IR Window flame proof?

NO. Flameproof is a term used when designing hazardous area equipment. The materials used in the construction of the IW Series IR Windows are all flame retardant and certified by Underwritiers Laboratories (UL) to UL94.

Is Your IR window more accurate than the competitions?

The IW Series Intelligent IR Window on its own is not more accurate than any competitor Window. The introduction of the transmission correction data given in RoutePLANNIR™ and on the IW Series Installation App on each individual IW Series Windows allows the user to gain the exact correction data for that window and in turn giving you the user a more accurate reading.

What are the thicknesses of your lens materials?

Our standard crystal thicknesses are:

IW3000 – 2mm (0.08in)
IW4000 – 4mm (0.16in)

Who can install and service an IR window?

The IW Series Intelligent IR Window must be installed and serviced only by qualified electrical personnel, in accordance with local safety codes and legislation

Why is the actual transmission rate so important?

All Infrared windows transmit infrared energy at varying levels, this is known as the transmission rate. The IR Window transmission determines the amount of infrared energy the thermal imager receives and correspondingly, the temperature the camera displays to the thermographer. To be able to calculate the temperature of a component behind an IR Window there are a number of variables for the operator and camera to consider which include:

  • IR Window Transmission
  • Target Emissivity
  • Ambient/Background temperatures
  • Distance

With all of these variables and measurements taken into consideration the camera will use this data to calculate a temperature using a sophisticated algorithm. Without all of these variables it is difficult to get an accurate temperature reading from your target located inside the panel.
The IW Series Intelligent IR Windows are all individually transmission checked across the general operating range for an electrical pdm inspector (+35C – +165C). The broad calibration routine enables the IW Series IR Windows to access specific calibration maps which take into account the spectral nature of a typical IR Window transmitter.

No other IR Window manufacturer provides this level of accuracy to thermographers. For more information on IR Window transmission go to our Learning Lab section and select the “Understanding Transmission” Lab.

You say that TC7150 is compatible with the IW Series SMART IR Windows, what does this mean?

Both TC7000 and TC7150 have onboard 13.5Mhz RFID scanners which means that they can communicate directly with the IW Series SMART IR Windows. The SMART IR Window wirelessly responds with a unique ID code embedded in a chip within the IR Window which enables the camera to download transmission specific data for that IR Window type from the CorDEX Servers.

Once the camera has this data, it automatically tags images taken via the IR Window for later seamless correlation via CorDEX CONNECT database software. The camera also automatically enables complex on-board correction algorithms to remove the error caused by the IR Window itself.

The result, accurate measurements with no more pen and paper attempts at correlating hundreds of IR Window images with the correct location. The combination of TC7000, IW Series SMART IR Windows and CorDEX CONNECT database package takes the load and provides accurate results, every time.
