Infrared window
Infrared windows and the trend of use in modern factories
Did you know infrared windows help engineers inspect electrical cabinets safely and save time. Discover the usage trend and Fluke, FLIR options at EMIN in the article below.

Why maintenance engineers need infrared windows
During maintenance shifts, an electrical engineer often faces great pressure when inspecting live electrical cabinets. If opening the cabinet directly, they are forced to shut down the entire production line, perform a series of safety steps, from wearing arc flash protective gear to requesting temporary power-off permits. A task that seems like just a few minutes of temperature measurement can take hours. Infrared windows completely solve this problem. With a small observation port fixed on the cabinet door, engineers only need to place the thermal camera against it to read the internal temperature condition. This not only saves time but also reassures them knowing they are not directly facing the risk of arc flash.
Actual usage behavior of customers
Market reality shows that infrared windows are favored by two main groups. Large manufacturing enterprises see this as an indispensable part of their safety strategy. For them, each electrical incident is not only equipment damage but also carries the risk of occupational accidents, affecting reputation and insurance costs. Therefore, they install infrared windows as a long-term preventive measure, similar to how they invest in fire protection systems or gas leak warning systems. The second group is electrical maintenance service companies. With a continuous workload, they need a solution that allows quick inspections while remaining professional in the eyes of their customers. Infrared windows help them shorten the time of each inspection shift, thereby increasing productivity and expanding the number of service contracts.
Fluke and FLIR meet needs in different ways
It is not difficult to see that Fluke focuses on mechanical durability and stability under heavy industrial conditions. Fluke’s infrared window models often feature sturdy designs, durable sealed gaskets, and strong impact resistance, suitable for steel, cement, or oil and gas plants. Meanwhile, FLIR positions itself towards flexibility. They offer many sizes and materials, from compact round windows for low-voltage cabinets to larger models for medium-voltage systems. Some models are even optimized to integrate with FLIR’s dedicated thermal cameras, providing sharper images during observation. Users can therefore choose a solution suitable for their specific environment and production scale instead of having to accept a common design.
Long-term value far exceeds investment cost
Initially, many businesses often hesitate about whether to spend money on an accessory as small as an infrared window. However, actual operation has proven its outstanding value. An unplanned production line shutdown can cost hundreds of millions of VND, not to mention accident risks. With infrared windows, engineers can perform periodic inspections without shutting down machines, meaning businesses completely minimize unwanted downtime costs. Many customers, after a few years of use, have returned to equip their entire system, because they clearly saw the savings far outweigh the initial investment.
Customers can directly find models such as FLUKE CV300, FLUKE CV401, FLIR IRW right at EMIN.
Infrared windows are becoming a new standard
The industrial electrical market is changing very quickly. What used to be considered optional is now gradually becoming a mandatory requirement in many bids. Infrared windows are part of that trend. As factories increasingly care about safety and maintenance efficiency, this product is no longer seen as a supplementary device but as a standard to evaluate professionalism. The shift from old habits to new ones shows that infrared windows are playing an important role in elevating operational management, helping businesses move closer to international standards in safety and predictive maintenance.
