The Visible Defects Heat Exchanger Inspection System enables the technician to better evaluate the integrity of a heat exchanger by visually enhancing a crack if it exists. The accessories in the kit allow the technician to inspect clamshell/serpentine designs by applying penetrant on the air side of the heat exchanger and then inspecting inside the combustion chamber with the UV flex light for penetration due to a defect. For tubular heat exchanger designs, the solution is sprayed inside the combustion chamber and then inspected with the UV flex light on the air side from the blower compartment.

The Visible Defects Kit includes:
  • High pressure sprayer assembly
  • Quart of Visible Defects Crack Finder solution
  • 22" sprayer wand
  • 12" extender/injector
  • LED UV flex light and batteries
  • UV protective glasses
  • Set of instructions and customer handouts
