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.

The Next Generation in Round Infrared Windows

  • Poly-View System™ Technology

    An evolutionary step in infrared (IR) windows, the VPT Series utilizes our exclusive Poly-View System™ technology enabling visual inspections, traditional IR inspections utilizing cameras across the entire IR spectrum.

  • Industrial-Grade with Patented Reinforced Grill

    The VPT Series windows are industrial-grade with a patented reinforced grill that exceeds high voltage switchgear viewing pane standards and are available in 2’’, 3’’ and 4’’.

  • Lockable, Easy-Grip Stainless
    Steel Cover

    IRISS VPT Series window come with a lockable, easy-grip stainless steel cover that maintains IP65/NEMA 4 seal when closed. Grip covers allows for private labeling for original equipment manufacturers..

Our Strong Points Ipad

Tested and Certified to The Highest Industry Standards

IRISS IR windows are the most certified windows in the industry with IEEE (impact & load), UL, cUL, Lloyds and CSA C22.2 14-13 for industrial control equipment Check out this product certifications!

  • UL 50V

    UL 50V applies to infrared windows and is more of a classification than a standard that applies for performance-of-build characteristics.

  • CSA C22.2 No. 14-10

    Canadian Standards Association shows that a product has been independently tested and certified to meet recognizable standards for safety and performance.

  • UL 508 & 508A

    UL 508 and UL 508A are classification for the components used on electrical panels. UL 746C is a standard requiring flammability and impact tests for polymeric materials used on electrical equipment.

  • IP65/NEMA 4

    These equivalent ratings certify enclosures for indoor or outdoor use. They protect against access to hazardous parts, ingress of foreign objects and water from rain, sleet, snow, splashing or hose directed water & ice formation damage.

  • UL 50E

    UL 50E standard applies to enclosures for electrical equipment intended to be installed and used in non-hazardous locations.

  • Lloyd’s of London

    Lloyd’s provides independent, third-party approval certificates attesting to a product’s conformity with specific standards or specifications. It verifies the manufacturer’s production quality systems through a combination of design reviews and type testing.

  • UL 1558

    Requirement covers metal-enclosed, low-voltage power circuit breaker switchgear assemblies containing but not limited to low-voltage power circuit breakers, switches, control, instrumentation and metering, protective and regulating equipment.

  • American Burea of Shipping

    An ABS assessment is the pre-approval of a product for use on a variety of ABS- classed ships following a technical evaluation. Ship designers, builders and owners can select the product to be placed aboard and ABS-classed vessel.

  • UL 746C

    Sets the impact & flammability standards for polymer materials used in electrical equipment to 1500 volts. Plastic/polymer parts of an IR window must pass flammability tests at room temperature & remain intact during an impact test performed at 0°C (32°F).

  • IEC Vibration & Humidity

    Certified IRISS IR Windows experienced no obvious signs of damage due to vibration or extream humidity when put under IEC testing conditions for IEC 60068-2-6, 60068-2-3, and 60068-2-78.

  • DNV

    DNV Certification is awarded for marine and offshore applications and allows preventative maintenance on electrical equipment in these vertical markets. DNV covers Rules for Classification of Ships and Offshore Standards (vessels, tankers, military and cruise ships, and oil drilling riggs).

  • Arc Rating / Arc Testing

    Eaton:
    IEE C37.20.7 Type 2B: 63kA, 15kV for 30 cycles at 60Hz
    IEC 60298 Appendix A: 63kA, 15kV for 30 cycles at 60Hz
