Every late autumn, plant heaters kick on and suddenly powder lines start fighting bizarre adhesion defects.
Shop air dries out fast once the building heat runs steady. Dry air increases electrical resistance, which kills your transfer efficiency and leaves thin spots on inner corners. Crews usually react by cranking gun voltages or slowing the line, but that often creates heavy back-ionization instead of fixing the coat.
Running a quick check on your booth humidity and grounding rods saves hours of chasing ghost problems on the line.
Do you see your powder transfer rates drop once heating systems start running?
