The CAP-ENV-PD Series

The Toughest and Most Reliable Infrared and Ultrasound Window

Overview Image

Overview

The CAP-ENV-PD features a reinforced environmentally sealed door design while also providing a large visually clear infrared (IR) transmissive viewing area. The CAP-ENV-PD also comes equipped with a versatile port for ultrasound inspections – an ideal way to identify electrical faults. Initially developed for MV transformer and switchgear applications. The CAP-ENV-PD is a perfect combination solution for medium and high voltage applications where both IR and Ultrasound inspection is desired.

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. The preferred choice for OEMs in UL-listed arc resistant switchgear, our patented window design brings higher levels of both safety and reliability.

Patented Poly-View Optic Design

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.

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 and distribution, as well as the quality of products we offer.

Features

Tested and Certified

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,

Proudly Made in the United States

IRISS manufactures and assembles all products at our global headquarters located in Bradenton, FL.

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. 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.

Unparalleled Field of View

Unlike the round infrared windows the large format IRISS CAP series and custom infrared windows have a far superior field of view. The CAP-ENV-PD series has over 6 times the FOV of a 4-inch diameter round window which give the thermographer the ability of infinite viewing angles inside the switchgear. Reducing the number of infrared windows needed typically reduces the cost of the installation and product purchases required by over 50%.

Fixed and Stable Transmission

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.

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.

Built-in Ultrasound Inspection Port

Quickly and Safely perform closed panel airborne Ultrasound inspections of electrical equipment including Switchgear, Switchboards, Panelboards, Transformers, Motor Control Centers and Process Equipment Panels. Through the CAP-ENV-PD’s built-in Ultrasound Inspection Port compatible with IRISS PD and TEV testing devices such as the Sonus XT & Sonus PD to detect early warning signs such as Arcing, Tracking, Corona and Partial Discharge.
