Produce-Mister Humidity Is Causing Nearby Duct Sweating
Treat the misting area as a local high-moisture condition and verify the specified insulation, vapor barrier, exposed hardware, and air leakage. Do not assume a different wrap or stainless hardware without project confirmation.
This branch only sweats when the produce misters run. I checked the wrap and found exposed metal at the support plus a damaged jacket seam. Can we confirm the specified repair for this wet zone?
Watch out
Do not choose a new insulation system or hardware material from a generic grocery-store rule.
Check
Confirm whether the moisture appears only during mister operation.
Inspect nearby collars, grilles, supports, access doors, and insulation seams.
Check whether the installed material matches the approved insulation and finish schedule.
Document recurring wet locations and any corrosion or damaged jacket.
