Certified Infrared is Proud to offer the new Iriss IR inspection window.

The IRISS VPFR (Viewing Pane Fixed Re-enforced) range of IR windows use the IR1 & IR2 lens assemblies. These are the first infrared viewing pane lens assemblies to be tested for the impact and flammability requirements of UL standard 746C 6th Edition and 508A as well as the impact and load requirements of IEEE C.37.20.2 section a.3.6 and pass.

Features of the IRISS VPFR Range of Viewing Panes:

VPFR Lens Assembly is recognized to UL 508A and 746C for Flammability and Impact Resistance
UL94 5VA Flammability Rated Assembly
IEEE C37.20.2 Compliant For Metal Clad and Station Switchgear
IP65 / NEMA 4 Rated Both Open & Closed
Allows Safe Thermal Imaging of Fully Energized Electrical Components through Closed Doors
Suitable For Use With All Makes of Infra Red Cameras
Available in 2, 3 & 4 Inch Viewing Diameters
Manufactured Using Non Conductive Materials
Simple Installation in 10 Minutes

Important Safety Note:
The VPFR Range meets the mandatory IEEE standard (C.37.20.2 section a.3.6) for Visual viewing panes in medium and high voltage electrical equipment (36 kV Metal Clad and 72 kV station switchgear) and allows IR inspections to be completed safely in line with the requirements of NFPA 70e. No other Infra Red Viewing Pane assembly available today can meet these requirements (severe pressure, impact and flammability).
