Techni Ice

[d2dave]

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 ?

[d2dave]

Overnight.

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

[Debacle]

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?

Icebrick, damn i put in a house brick and it didnt do a bloody thing :p.

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:Rolling::Rolling:

We used techniice for a while when we bought an ice box from them. The ice box was/is fantastic but the ice brick/cube things seemed to leak a little and we had some residue on stuff we and we ended up throwing them away. The ice box on its own with normal ice is really fantastic anyway.

Don't start that argument. I have just finished reading an E v W on another forum. It started good but as expected it turned into a 5 page bun fight, even got nasty at times.

We have 2 eskies, one 60 litre, one ordinary bbq size. Went to Karumba from Brisbane , put large block of dry ice in the 60 litre esky. along with bags of ice. Transferred ice to the small esky as needed, still had dry ice when we arrived at Karumba.Would have needed more dry ice for the trip back if fish were involved, from what I have been told, the techni ice takes the place of bags of ice quite well, Bob

We use techni-ice at work for keeping intra-venous fluid cool. The stuff is used in the same way as a freezer block and with the same effect, an advantage is that the flexible sheets can be wrapped around items or shaped to suit a container. When thawed it oozes a sticky, gooey residue.

So why would you use it if it leaves an unpleasant residue. Is it toxic?
At least ice residue is drinkable.

We have been using it within standard eskies for a couple of years now, it does everything they say. I tested it when I first got it and it stood up to manufacturers claims. Would love a 'proper' ice chest (as they also sell) but honestly haven't needed it as yet.

Recently, I have been adding a few of the old fashioned blue ice block bottles to get an extra day or two out of it when family camping. Not sure if this helps, but it makes me think it does so hence feel good about it too!

Same here, I have kept the cube sheets and use a few on top but the ice box stays colder for longer with a few 2 ltrs coke bottles full of frozen water. Get to use the water as it thaws during a trip.

[Hoges]

The techi ice might indeed stay cold for a long time...but... is it efficient at absorbing heat from a warmer "body" thereby cooling it? Alternatively they've got some goo inside the pack which has a different "specific heat" from the usual glycol stuff and therefore requires more heat input to raise its temp. etc etc.

Frankly all that screwing around with ice bricks (other than to keep the beer cool for a SHORT drive) is why I bought a "bushman"...

Ok but my FridgeMate is ......:wasntme:

The product we tend to use is possibly described as "not so techni ice"!
My everloving spouse recycles her used wine bladders (and there are a few of them:)), slowly drains them out, (this can take up to a number of nights!) refills them with water and freezes them. (You will easily work out how the stopper can be disassembled.) Has similar effects to techni ice (contained and reusable) except that should it eventually leak it is only water, or in some cases salted water.
She also houses them under an aluminium cake tray on the bottom of the esky (when we use an esky) and this not only insulates the "ice pack" but also keeps any foodstuff stacked on top away from any leakage should same occur.

The ally tray sounds like a good idea, Out to the shed I go.....

We just bought an 80ltr Ice chest from them as I have wanted one for years and finally SWMBO decided it was her idea so we got one.

Just fits in the back of a Disco long ways and the plan is to have that and the Weako freezing the Techni Ice/ Bottles of water and then dropping them in the Ice box.

The Weako seems good as a freezer but is hard to keep constant as a fridge (insert Engle etc jokes in here) and they work better full so I have always just topped it up with bottled water when traveling anyway as the stuff was used.

We find now with 3 kids one a 14 year old boy that the Waeco isn't big enough so dollar for dollar that seemed the best way to go.

I have heard nothing but good stuff about the Techni Ice, a mate uses it in his Icebox all the time and he's off hunting and fishing for weeks on end and recons it's the only way to keep food and beer cold for long enough.

A friend of mine used that technique and said it worked well for him. The smallish fridge/freezer was used just to create ice while he was driving to put in the bigger ice box.

Well, I plugged in my:

Waeco 50
Engel 40
Primus 55l Dual

Set all of them to 3c

Guess what... They all do a great job :cool:
