Trane recommends that coated waterboxes/tubesheets - regardless of the type of protective coating included - be taken out of service within the first one to three months of operation for inspection.

Any voids or defects identified upon inspection?

If voids or defects are identified, they must be repaired.

Is the water quality known to be highly supportive of corrosion (i.e., sea water, etc.)?

If yes, inspect the coating system at one month.

Is the water quality known to be relatively benign (i.e., normal treated and clean condenser water)?

If yes, inspect the coating system within three months.

Did the initial inspections show no problems?

Only when initial inspections show no problems are present should subsequent maintenance intervals be increased.
