VPT Series

An evolutionary step in infrared (IR) windows, the VPT Series 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 VPT Series IR windows are industrial grade, with a patented reinforced grill that exceeds high voltage switchgear viewing pane standards.

$145.00 – $330.00

Arc Safety Tested

Successfully tested to the IEC 62271-200 standard for arc containment on metal enclosed switchgear assemblies to help protect workers from injury/fatality.

Durable and Rugged

Polymer based IR windows are far more able to resist the mechanical stresses applied to IR window that are fitted to electrical distribution equipment.

UL Listed

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.

Features

Durable and Rugged

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.

Unconditional Lifetime Warranty

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.

Fast and Easy 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.

Environmentally Sealed Design

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.
