SubscriberI have an insulated plate separating a cold (-40C) and hot (+30C) chamber with electrical wiring running running through a hole in the plate. I am running into issues with the hot air infiltrating the cold side and condensing / freezing on the electrical wires, the wire connector on the cold side, and the unit on the cold side. I need a non-permanent, easy to install / remove solution to help minimize warm air infiltration from one side to the other to limit the amount of condensation and eventual freezing.
Any suggestions?

Thanks for the question Brian! Having a removable and airtight seal is a particularly challenging application, especially when temperature cycling is concerned. Initially I would suggest trying 3M™ Extreme Sealing Tape 4412N. It is a thicker adhesive that should conform over the wires. Also, it should be able to be removed cleanly depending on the insulated plate material. I would use a test piece on the plate material. Please comment below if you’d like to share additional details that could help refine your options.
Thank you ACotter! I will order some of that tape and try it out and see if it solves my problem so I know how to approach a long term solution. Another interesting challenge to this puzzle is that I don’t have control over the installation and the person doing the install is a non-technical person so asking them to do much extra during install may be too much.
