IRISS Infrared Safety Windows
IRISS polymer safety windows are high quality products designed to offer maximum safety and utility.
Use of Infrared Windows Helps Eliminate Risks Associated With Live Inspections
Use of Infrared Windows Helps Eliminate Risks Associated With Live Inspections The first rule in any health and safety situation is the elimination of risk and heavy Personal Protection Equipment (PPE) should always be the last resort. The use of infrared (IR) windows in any thermography program eliminates the risks associated with live inspections by ensuring that thermographers are not exposed to any energized components and can complete the infrared survey with minimum disruption to plant and services in standard workplace PPE. By ensuring live IR inspections are completed safely by one operator, you can expect better ROI on IR cameras and reduced risk of premature failure of plant through more frequent inspections.
How to Choose the Right Type of IR Window for Your Application
The materials available for infrared window optics are diverse and have a wide variety of transmission rates and mechanical strengths. It is advisable that when considering the use of IR windows, you seek advice from IR window manufacturers and IR lens material suppliers before deciding the materials and window styles best suit your application.
There are a number of sources from UL, IEEE, & NEMA that can be referenced to give the user guidance on the issues relating to installation and the use of IR windows. Listed below are just a few:
UL50V: The UL standard that applies specifically to infrared windows.
UL508 and 508A: Are classifications for components used on electrical panels.
UL746C: Is a standard requiring flammability and impact tests for polymeric materials used on electrical equipment.
IEEE C37.20.2 Section a.3.6: Is the impact and load requirement for all viewing panes installed on mediumand high-voltage switchgear (above 1kV).
Ingress Protection Standards: Certify that an enclosure is capable of sealing out various levels of environmental contaminants.
IP65 and NEMA 4 are equivalent standards indicating protection against dust and water ingression.
The Evolution of the IRISS Infrared Viewing Pane
1997 - VPC Crystal Window (Aluminum Housings)
Original IR windows were produced using Aluminum constructed housings and used Calcium Fluoride, Barium Fluoride and Sapphire crystals as the IR window lens materials. These were both round and square depending on the application.
2000 - VPC Crystal Window (Plastic Housing)
Aluminum IR window covers and bodies were superseded by plastic to enhance the safety of the product by ensuring that the assemblies were non-conductive. This also allowed the product to be mass produced and allowed the unit costs to be reduced. Products still used Calcium Fluoride, Barium Fluoride and Sapphire crystals as the IR window lens materials.
2003 - VPF IR Polymer Window
Plastic IR window covers and bodies were a great success and improvements were made in design which became the standard design material for IRISS IR Windows. We were however concerned about the problems regarding Fluoride crystals as users of IR windows were unhappy with inconsistencies in IR transmission and failure through breakage and water ingress. IRISS conducted an extensive search for replacement materials that could be used to replace Fluoride crystals, eventually we found IR transmitive polymers with the required IR transmission and the ability to resist impact and also resistant to water and light acids & alkalis. Hence the launch of the VPF range of IR windows. It was at this stage that the IRISS range of IR windows were UL Certified to UL508 & 508A, and tested to IP65/NEMA4 open or closed. iriss.comThe Evolution of the IRISS Infrared Viewing Pane Tech Byte
2005 - VPFR IR Polymer Window (IR1 Plastic Reinforced Grill)
Further investigations into relevant standard showed IRISS that there was a lack of understanding in what standards were applicable to IR windows, especially surprising was the fact that UL only certified to 1500Volts! We decided to build a window that could pass the requirements for a standard viewing pane fitted to electrical switchgear as stipulated by IEEE C.37.20.2. This test was completed by supporting the IR polymer with one plastic IP2X grill in front of the polymer, this also ensured that in the event of a lens failure the window would always fail safe!! The VPFR IR window became the first and only IR window in the world to give an IP65/NEMA 4 IR lens assembly to meet this standard.
2005 - VPFR IR Polymer Window (IR1 Plastic Coated Aluminum Grill)
As a further enhancement to the successful VPFR range of IR windows IRISS superseded the plastic reinforced grill with a plastic coated Aluminum grill and subjected the assembly to the test standard UL746 C, this tested the lens flammability and impact resistance of the lens at 0°C, the lens system easily passed this test and is the only IR window lens system that holds this certification in the World.
2006 - VPFR IR Polymer Window (IR2 Plastic Coated Aluminum Grill)
IRISS decided to further improve our VPFR range of IR windows by using 2 IP2X Aluminum grills, effectively sandwiching the polymer lens to produce a lens assembly that is able to resist constant impact from a 5lb hammer, passed the UL 5 inch flame test, has excellent IR transmission, is resistant to water, light acids and alkalis and is guaranteed for the life of the installation. In short the IRISS VPFR range of IR windows is the “ULTIMATE IR WINDOW SOLUTION” on the market today.
2007 - VPFR IR Polymer Window (IR2 Plastic Coated Aluminum Grill), IRID Labels & VP-12-US
IRISS upgraded the VPFR Series design by reinforcing two IP 2X grills. This effectively sandwiches the polymer producing a lens assembly able to resist constant impact from a five pound weight and pass the UL5 flame test, unsurpassed to date. IRISS launched a range of IR-ID labels for emissivity reference points. The VP-12-US (Ultrasound Port) is a 0.5 inch ultrasound port with an attached cover that can be used alone or in combination with IR windows.
2008 – Transmissive Panel Cover (TPC)
IRISS is the only company to date to offer custom-designed and fabricated TPC’s. Our TPC’s can be made to virtually and specification (shape, size, material, color, etc.) at a competitive price and attractive lead times. iriss.comThe Evolution of the IRISS Infrared Viewing Pane Tech Byte
2009 – CAP Series
Recognizing the industry needed IR windows with a better field of view (FOV), IRISS developed and began manufacturing the CAP Series. Available in 6in, 12in and 24in, the expanded FOV allows inspection of multiple components through one window, reducing installation time and costs.
2010 – Custom Solutions
IRISS is the first company to design, fabricate and assemble IR windows in various custom sizes, shapes and colors. Custom solutions as large as 60+ inches in length are being made to retrofit switchgear across the country.
2011 – VPIC (Internal Cover) & UL and ABS Certification
Released the VPIC Series featuring an internal cover providing superior protection in environments where dust and debris are a mitigating factor. IRISS received certification from UL and ABS across all new and existing IRISS product lines.
2012 – Platinum Series (Featuring Poly-View System™), SMART Academy, US Patent, and Private Label and Easy-Grip
Released the Platinum Series featuring the Poly-View System, the industry’s first and only clear polymer lens allowing visual, UV and short/mid/longwave IR spectrum inspections. The industrial-grade optic allows for a larger field-of-view and boasts a Fixed and Stable Transmission – far superior to crystal windows. IRISS knows working SMART is not hard. This is why we founded the Safety and Maintenance Academy of Reliability Technologies training academy for electrical maintenance staff in the correct use of available tools and techniques to ensure safety and reliability. IRISS received official US Patent on all IR window polymers and reinforced grill designs. Optional Private Label and Easy-Grip cover added to the product lines. Private Label permits your logo and packaging on our state-of-the-art patented technology.
