Visible Defects Heat Exchanger Inspection System
Nu-Calgon’s Visible Defects Heat Exchanger Inspection System is complete kit for identifying and locating cracks in the combustion cells of gas furnaces. If a crack exists, the fluorescent penetrant makes the visual identification simple.
Benefits • Better visual inspection of gas heat exchangers as instructed by the International Fuel and Gas Code “for cracks, openings, or excessive corrosion” • Fluorescent penetrant and UV light make it easy to find potentially dangerous cracks in the heat exchangers • Can be used to evaluate clamshell, serpentine and tubular design heat exchangers in standard efficiency furnaces (non-condensing types) • Perfect tool for annual clean and check programs
Can You See The Crack?
Now You Can!

Concept The Visible Defects Heat Exchanger Inspection System places a fluorescent penetrant onto the combustion cell surface, utilizing a unique sprayer wand. The device can be inserted into the fan/limit control hole or the holes from the removal of sheet metal screws that secure the front panel on many gas furnaces types. The leak detecting pentrant is non-toxic, low odor, and non-smoke generating. When the penetrant is sprayed on the heat exchanger, it aids in locating a crack on the surface. If one is present, the penetrant is observed in the combustion chamber (or air side for tubular heat exchanger designs) when examined with the supplied LED UV flex light and inspection mirror.
Application The kit assists the technician to better see the integrity of heat exchangers in standard efficiency (non-condensing type) gas furnaces that have been in service for five years or more.

Description The Visible Defects Heat 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 for penetration due to a defect. For tubular heat exchanger designs, the solution is sprayed inside the combustion chamber and then inspected with a UV flex light on the air side from the blower compartment.
The supplied UV flex light illuminates the solution as it penetrates the combustion cell, indicating a potentially hazardous defect.
