V44BD 4″ (100mm) IR Window

The ViPIRS V44BD IR Viewing Pane incorporates a unique patented BLASTDOWN® arc-flash pressure relief system. Rather than attempting to contain the extreme overpressures created by an electric arc flash, the ViPIRS BLASTDOWN® system is designed to channel the energy through dedicated vents in the base of the frame.

The next-generation composite polymer optic used in the ViPIRS V44BD is compatible with the latest thermal imaging technology. You get an unparalleled field of view and image clarity thanks to its mesh reinforced polymer composite. Historically, infrared viewing panes comprising optics with transmissive polymers had to rely upon metallic mesh on one or both sides of the polymer sheet to comply with safety requirements. These twin mesh sheets resulted in potential image clarity and vignetting effect problems due to poor mesh alignment and angled imaging.

The ViPIRS V44BD composite optic uses a single mesh embedded within the polymer itself, creating a robust infrared transmissive optic that complies with the latest codes and standards but without issues associated with mesh alignment image distortion. With a smooth face on both sides of the optic, the V44BD is simple to clean and maintain ensuring maximum image quality and field of view.

Certified by Underwriters Laboratories (E516454), the American Bureau of Shipping (21-2156486-PDA) and CENEGEX (TEST-RTL-1046) for both indoor and outdoor installations into NEMA 250-rated Type 4/12 equipment and EN60529:1992 + A2:2013 IP55-rated equipment, the V44BD infrared viewing pane complies with the latest industry standards, including IEEE (impact and load), UL50V, UL746C and UL94.
