Hello, I am looking for another professional opinion for our new walk in freezer. The box is built by Norlake, the dimensions are 11' X 6' 10" x 7' 6" with 4" walls. The ambient box temp. is 110F with the unit on the roof in the northeast. We will be loading around 100lbs a day of food products at around an 85F average temp. We might be in and out of the box 20x a day with minimal time inside the box. Let me know if I can give you any more specs to work with, Thank you.
