The garage at rainbow has a freezer full of block ice . I buy crushed ice from coles at $1.30 for a 5kg bag .

hey Glenno.. looks like we went to the wrong garage!
I do the same, the ice at WW and Coles is definately cheaper!

sorry if i wasent clear earlier but the fridge is everkool the ice box is a different brand,if the ice boxes have this great seal wouldnt the fridges benefit also from improved sealing????????????

Hey porl - what are you saying? That the frozen bottles you put in were still frozen next morning or that the water bottles that were to be chilled were frozen? If the latter were your originals still frozen?

porl posted:

hey moose, the frozen 2L water bottles were still solid and the warm 350ml bottles of water that were put in the night before were either fully frozen or half frozen.

Moose posted:

Porl - what the hell were you on at the time? LOL. Sounds like a physical impossibility to me unless you had some magic liquid in them bottles. Might have to run this by Dr Karl!
Cheers - Moose

I agree Moose, it defied my knowledge of thermal dynamics (not that i have much), but it kept happening.

All I can think of is that the frozen bottles were at something like -ve 20C and they lost so little of their coldness due to the quality seal and insulation of the evakool that they managed to bring the small water bottles down from lukewarm to say a -ve 5 which maybe over 10 hours was enough to freeze them. Mind you, i probably it was probably the water bottles in direct contact with the frozen 2L bottles that ended up frozen.

revhead, looks like you need to rethink your plans, if you believe the EvaKool will freeze the complete fridge unit, maybe you need a second or even a third opinion :-)
before you let the fish spoil due to the fridge not being able to freeze the entire contents.

(reprinted below with only relevant EvaKool information left intact)

"we took an everkool 12v/240v 47 litre fridge/freezer,we removed the moveable partition from the everkool thinking that on "MAXIUM" setting all contents would ultimately freeze....
result;
the food in the freezer compartment would remaim frozen, temps varied with usage but typically around -5 to -10
however most of the food in the larger chamber would not maintain minus temperatures but would be ABOVE freezing"

"I now don't believe that these units are capable to freeze the entire contents in the same way as another popular make, simply because of the shape and configureation of the cooling panels, they simply can NOT freeze food that is some distance from the cooling panels, just my observation not bagging the product"

You need a decent compressor and battery system to fully and completely freeze and to actually keep frozen a normal 12v fridge.
Would like to see tests from other fridge users under similar conditions.
