VPT Series
First and Only Round Transparent Polymer IR Window
First and Only Round Transparent Polymer IR Window
An evolutionary step in infrared (IR) windows, the Platinum Series VPT utilizes our exclusive Poly-View System™ technology to allow the use of any thermography camera to monitor energized electrical equipment. The world’s only clear polymer IR window optic enables visual inspections, traditional IR inspections utilizing cameras across the entire IR spectrum and allows for UV inspections to be performed with a corona camera. The Platinum Series VPT IR windows are industrial grade with a patented reinforced grill that exceeds high voltage switchgear viewing pane standards.
Successfully tested to the IEC 62271-200 standard for arc containment on metal enclosed switchgear assemblies to help protect workers from injury/fatality. The preferred choice for OEMs in UL-listed arc resistant switchgear, our patented window design brings higher levels of both safety and reliability.
Our exclusive polymer technology is unaffected by environmental stresses, and enables visual, IR, and UV inspections across the entire Infrared spectrum. This original design is able to resist mechanical stresses and is tested and certified to meet mandatory impact/load requirements beyond the capabilities of crystal-based windows.
Having passed rigorous standards and testing, our inspection windows are UL Listed (E491496). This demonstrates our dedication to continued safety and security in the ever-changing world of electrical power and distribution, as well as the quality of products we offer.
Polymer based IR windows are far more able to resist the mechanical stresses applied to IR window that are fitted to electrical distribution equipment. It was IRISS that first came to market with industrial grade IR windows that could meet the mandatory impact and load testing requirements of UL, CSA, IEEE, IEC, CE testing that could never be passed by any crystal based IR window.
IRISS IR windows are the most certified windows in the industry with IEEE (impact & load), UL, cUL, Lloyds, CSA 22.2 14-13 for industrial control equipment. Our marine certifications are Lloyds, DNV and ABS (American Bureau of Shipping) credentials. IRISS IR windows are also arc tested to IEC 62271-200 Arc Flash Spec test 1.1 Second Duration, IEC 60262271-200: 63kA, IEC 60298 Appendix: 63kA, IEEE C37.20.7 Type 2B: 63kA,
IRISS manufactures and assembles all products at our global headquarters located in Bradenton, FL.
The IRISS Unconditional lifetime warranty is unique in the IR industry as it not only applies not only to the workmanship of the window housing but also applies to the durability and stability of the optic in the proposed environment. No other manufacturer can offer this because crystal optics will fail over time, and are only able to at best offer a limited lifetime warranty for manufacturing defects
Polymer based infrared windows are unaffected by the environmental and mechanical stresses that degrade the transmission of crystal-based IR windows which are fragile and hygroscopic (even when coated). The polymer IR window systems will maintain fixed and stable transmission (FAST) for the life of the installation ensuring that the temperature data collected through the IR window is accurate and reliable for the whole life of the installation.
Following a few simple instructions, IRISS inspection windows can be quickly installed on switchgear and MCC panel covers, as well as transformers and other electrical equipment. Each window comes with an installation guide, as well as links to installation videos.
The VPT Series of products are constructed from switchgear grade Nylon plastic with an aluminum cover and stainless-steel mounting screws. Seamless custom gaskets ensure the NEMA 6 / IP67 ingress protection rating is maintained.
