Any recommendations on thermal breaks for ducts passing through freezer walls? I have a -25 deg F freezer in which I will be installing desiccant dehumidifiers. I will be ducting reactivation air in and out of the freezer and passing through the adjacent 70 deg F space to the outdoor. My inlet air will be ambient as high at 95 deg F, and I don't yet know my outlet air temp. I am thinking it will be around 200 deg F. I'm trying to get in touch with the manufacturer (Munters) to get a recommendation on material, but I am suspecting they will suggest sch 80 CPVC.
Even assuming plastic, I will need some form of thermal break in the duct, correct? I will be insulating the duct, of course.
Any thoughts or recommendations on passing through the freezer wall?
