Calectro's stand pairs dark backdrops reading "HVAC sensors" and "Duct smoke detectors" with the line "Swedish innovators in HVAC since 1969". Product images of sensors and detectors fill the graphics, and a small table holds sample devices. Visitors gather at the counter in front of the black-and-yellow branding.
