From Agema to G609: The Evolution of IR Furnace Cameras

Flir G609 High Resolution Furnace and Boiler Inspection Camera

IR technology in furnace inspections has evolved significantly over the past three decades. Early tools such as the Agema 550 and Inframetrics 390 laid the groundwork for remote temperature diagnostics in extreme environments. These early cameras were bulky and required extensive setup but opened the door to non-contact thermal inspections. Later, Flir's GF309 became the workhorse of the industry, offering real-time thermal imaging through flames with improved ergonomics.

However, the GF309’s 320 × 240 resolution limited its ability to detect fine anomalies, especially at a distance. Czajkowski recognized the need for greater clarity and transitioned PROtect to the Flir G609, which features a 640 × 480 detector. This allows PROtect technicians to detect smaller anomalies—such as hot spots, coke buildup, or insulation breakdowns—earlier and from safer distances.

What’s New in the G609

• Improved Heatshield Design.  Redesigned heatshield mounts with a single screw, features adjustable length and removable skirt, making furnace inspections safer, faster, and easier to use in the field.
• Advanced Furnace Lens. A single‑piece furnace lens attaches directly to the camera, eliminates external optics temperature compensation, and enables clearer inspections deeper inside furnaces from farther away.
• Higher Image Resolution. A 640 × 480 detector and redesigned cold filter deliver sharper images and better transmission through flames, revealing fine‑detail issues like tube bowing and hanger gaps.
• Connected Inspection Workflow. Built‑in Wi‑Fi with Flir Ignite enables automatic image uploads, simplified storage, and easy collaboration,so inspection data is accessible, shareable, and securely backed up.

Complete Solutions: Pairing the G609 with Software for Maximum Impact

What truly transforms the inspection process is the integration of Flir’s Thermal Studio Pro software. With the Route Creator tool, inspections are no longer reactive—they’re pre-planned and executed with precision. Technicians follow a defined route with inspection points loaded into the camera, eliminating guesswork and ensuring consistency.

After inspections, images are automatically organized by inspection point, and reports are generated in minutes using professional templates. This saves countless hours of manual sorting and documentation, freeing up inspectors to focus on analysis and decision-making. According to Czajkowski, "This combination of camera and software creates a seamless workflow—from planning to reporting."

The Flir routing software ensures the same inspection path is followed every time, making it easy to compare images across inspections—even in furnaces with dozens of viewports.

Real-World Results: Safer Plants, Better Uptime

By adopting the Flir G609 infrared camera and an integrated software approach, PROtect has helped clients detect issues like burner misalignment and developing coking conditions early, preventing costly shutdowns. In one instance, early detection of a developing hot spot allowed a refinery to schedule a repair during planned downtime—avoiding an emergency outage and saving hundreds of thousands in potential losses.
