[QUOTE="guest poster, post: 542725, member: 262401"] -30c water vapour is very quickly a solid... ice, not vapour or liquid. Ice build's up in freezers or Fridge ice boxes... .. leave the door open (& increase the ventilation(1&2)) and it will increase to the point where you'll just end up with a plug of ice, close the door and you can only freeze the moisture in the air in the fridge/ freezer- if there were no water vapour - no ice would form. 99% of ice that builds up in a freezer or ice box is from your kitchen /house. Every time you open the door of a freezer/ fridge, the cold, dry air drops out and onto the floor of your kitchen and draws the kitchen's warm, moist air in at the top. The moisture then condensates on the elements ....and quickly freezes (and still would with the door open & central heating on). In the case of sub zero temps, ventilation works the opposite way and outside there is rain etc. to deal with. There are plenty of low temp chemical processes that suffer from pipes being covered in ice. Whether ice build up would effect the LNB is another issue.. it might not adversly effect it anyway once it's sealed as you suggested and then sealed in lagging. Un-compacted ice is a good insulator anyway. A[I] meal time thought... :eek:[/I] [I].....all the ice in a freezer surrounding your food is made up of ... exhaled breath, evaporated sweat, evaporated bleach and cleaners, x amount of evaporation from your toilet, bath, shower, the dog's little accident, cigarette smoke, any drugs smoke, 1000s of chemicals given off by various products around the house, VOCs from redecorating, all laid down in layers ... it's actually quite full of ####.[/I]:eek: :cool: [/QUOTE]
