I am planning to install a blast freezer within a walk-in freezer. Someone has told me that there will be door issues since the blast freezer door is to be located inside the freezer.
I was told the inside door will most likely get stuck since the blast freezer temp will be at -40C while the freezer temp will be at -25C, and that door heaters normally can't handle below freezing temperature on both sides.
The blast freezer will also be run on an intermittent basis, so will I have to keep the heater on the door running even when it's shut?
Is there any way I can get around this door dilemma?
