What is the FLIR IRW-4S Stainless Steel IR Inspection Window?
The FLIR IRW-4S is a 4-inch stainless steel infrared inspection window designed for UK electricians and electrical maintenance engineers carrying out thermal inspections on live electrical panels. It allows safe visual and thermal imaging of energized equipment without opening enclosures, reducing arc-flash risk and downtime.
Built for harsh industrial and commercial environments, the IRW-4S enables routine predictive maintenance, fault detection and condition monitoring using FLIR thermal cameras. The Crystal IR optic ensures accurate thermal transmission while maintaining full safety compliance.
How does the IRW-4S improve electrical inspections on site?
By providing a permanent inspection point, the IRW-4S lets engineers perform fast, repeatable thermal surveys without removing panel covers. This improves safety, shortens inspection time and supports compliance with electrical maintenance best practice across industrial and commercial installations.
