Techni Ice

I tried a little experiment today. I got two sheets of Techni ice and placed in the bottom of my 40L Engel. The fridge was turned off and the thermometer showed 27 degrees.

Ambient temp was about 30 degrees and the sun was shining on the fridge I was curious to see if the Techni Ice could pull down the temp and by how much.

After about three hours I had a look and the temp in the fridge had dropped 11 degrees.

looks interesting -

if I have understood it correctly - you would have had it in your freezer initially - so I'm wondering what length of time you had it in the ffreezer ?

I tried putting an icebrick in an esky once. I was amazed at the result

[87County]

you're a cynic dobbo

manufacturer's blurb indicates that this stuff approaches the perfromance of dry ice - if this is true, then it could be very good

I've tried them and got about 4 days with 6 in my 60l poly food esky. Put 3 in a 80l fibreglass esky full of stubbies and soft drinks in party ice and there was still a cold slurry after 5 days.

My understanding is dry ice is a lot colder than your freezer will make these bricks. I cant see how they will get any colder than your freezer.
Whats the difference compared to ordinary freezer bricks?

Hi All. Wikipedia suggests that Dry Ice sublimates from solid to gas at -75 C approximately, so there is no way anything frozen in a conventional freezer is going to match it. My freezer claims to be operating at - 17C , so Dry Ice is way ahead on the cooling front. Doesn't mean Techni ice is not as good as water frozen over the same time in the same freezer. It is true that water continues to cool down the longer it is in the freezer, so it is best to use ice blocks that have been in there for more than a day or two. Cheers, 130man.

I just turn my Waeco on and it gets cold, just like a fridge/freezer
no need for ice
