ViPIRS V420BD 20” (500mm) IR Window (V420BD)

The V420BD infrared (IR) viewing window features a 4" x 20" viewing pane and incorporates our patented composite safety optic alongside the BLASTDOWN® pressure relief system for arc-flash protection. This design delivers unmatched safety and flexibility.

The ViPIRS V420BD utilizes a state-of-the-art composite polymer optic that works seamlessly with the latest thermal imaging technology, providing an exceptional field of view and image clarity through its mesh-reinforced polymer composite. In the past, infrared viewing panes with transmissive polymers required metallic mesh on one or both sides of the polymer sheet to meet safety standards. This dual-mesh design often caused issues with image clarity and vignetting effects due to misaligned mesh and angled imaging.

Unlike conventional IR windows that use 'arc containment' for protection, the ViPIRS range features a unique BLASTDOWN® arc-flash pressure relief system. Instead of trying to contain the intense overpressures resulting from an electric arc flash, the ViPIRS BLASTDOWN® system directs the energy through specialized vents located at the base of the frame.

The ViPIRS V420BD composite optic features a single mesh embedded within the polymer, resulting in a durable infrared transmissive optic that complies with the latest codes and standards while avoiding the image distortion issues linked to mesh alignment. With smooth surfaces on both sides, the V420BD is easy to clean and maintain, ensuring top-notch image quality and a broad field of view.

Certified by Underwriters Laboratories (E516454), the American Bureau of Shipping (21-2156486-PDA) and ExVeritas (21TEST0933) for both indoor and outdoor installations into NEMA 250-rated Type 4/12 equipment and EN60529:1992 + A2:2013 IP54-rated equipment, this infrared viewing pane complies with the latest industry standards, including IEEE (impact and load), UL50V, UL746C and UL94.
