Save Time, Save Money, Stay Safe

Industrial-grade VPFR series (Viewing Pane Fixed Reinforced) infrared windows from IRISS will enable thermographers to survey critical electrical applications more efficiently and much safer than before.
NFPA standards recommend infrared inspection under fully energized conditions; but PPE requirements and panel cover removal and reinstallation are time-consuming and therefore costly. Use of the VPFR series of products nearly eliminates the risks associated with infrared electrical inspection by providing companies with a noninvasive, closedpanel inspection methodology.
Thermographers inspecting through the window are never exposed to energized conductors or circuit parts, and are not engaged in risk-increasing behaviors as outlined in the 130.7(C)(9) of NFPA 70E. Consequently, the elevated levels of PPE prescribed by 70E for invasive surveys are not required when utilizing the IRISS VPFR series of infrared windows, thereby minimizing survey time while maximizing safety.

VPFR Features

• Industry’s ONLY impact resistant IRwindow: Patented reinforced opticexceeds high voltage
  switchgear viewing pane standards

• Stable transmission rates: Industrialgrade materials unconditionally guaranteed against
  transmission loss for accurate qualitative and quantitative analysis

• Born out of necessity: Created by a Level III Thermographer as the solution to hazards and
  shortcomings of traditional techniques / materials

• Manufactured from non-conductive UL94 plastics insulated to 30kV/mm

Specifications

he IRISS Industrial-Grade VPFR series was specifically designed to exceed the demands of the industrial and building maintenance communities' demands forimpact resistant IR windows with stable transmission rate. The VPFR windows from IRISS utilize materials that are unaffected by humidity, moisture, vibration, high frequency noise and a broad spectrum of acids and alkalis.
