Guys has anyone used dry ice to cool an eski?
Did it last long?
How much did you use for what eski size?
Any tips from those who have dome it.

I am going to use a large eski for general stuff and a seperate smaller eski for freezing.

Cheers Struth.

ive used it for aprox 50litre esky and it was great stuff but even though i put a tea towel down over the ice, it still froze the crapper out of all the stuff that was on top! by memory it kept icey cold for about 3 days in not hot but not cold weather! i give it a thumbs up if you use towels over the top of it etc!

what if you did a ratio of normal ice and dry ice?

I used 3 blocks in a 50 litre esky, and 1 bag of normal ice, at Summernats in Canberra, in Summer.
I used cardboard to protect the item, but it froze the ice into 1 solid block, at the bottom, and the meat, milk, fruit juice, and popped the Coke cans in the other esky that were on top of the cardboard.

Maybe a little less next time....

I have used dry ice in an 60 litre esky (made from the same stuff insulated truck trailers are made from) a few times. Here are the things I have learnt.

Keep anything you DONT want frozen up the top (cold air sinks). But chances are cans of drink will freeze regardless. So what we use to do (hope this makes sence) was use the dry ice esky as the main storage and just pull out what you need for the day and place in a normal ice driven esky.

Make sure any food in that esky is in AIR TIGHT packaging.

Open the esky as least as possible.

Leave the dry ice in the biggest block possible...dont break it up. (it lasts longer)

Keep a newspapper and wrap the blocks up with in
then put it in ya esky and dump a bag of ice on top and put ya stuff ya want frozen on top of the ice and work up

But if ya want it super duper cold. get some salt and sprinkl over the ice
for some reason it makes it extreamly cold tho it will melt faster

at fraser last xmas we used a 8 day dry ice block at the bottom of our 150 litre fibreglass esky and put food we wanted frozen in first then we put 30 kg of party ice in . Was only good as a freezer as every two days we got 2 days worth of meat out and some normal party ice and put it into our smaller fibreglass esky to defrost. just over 7 days it lasted.

Thanks guys.
What if I partitioned the esky, really cold side with dry ice, other side no dry ice.
Also put the dry ice into small tupperware containers to make dry ice bricks

Dont wnat to make camp on the first night and find everything frozen

Why am I disgusted but at the same time fascinated by this concept

I had a diesel fitter mate who said it was used on the mines sometimes to fit bearings and what not. Possible second application if you take it bush?

apparently they use it on engine sleeves as well

Nah real diesel mechanics use the workshops CO2 fire extinguishers to fit bearing races, cool beer cans, sources of thrust for creeper board drag races, etc...

Mate ran a block wrapped in newspaper with three bags of normal ice on top. (big esky)

On the last few days when he wanted the food from the bottom we had one giant block of ice The block had re frozen the melting party ice upon contact.
Bugga to break the food free

So yes, it works a treat \
Just use some form of partition or rack to keep your food off it

I have used it in the past. Wat we did was take two eskies. One had the dry ice in and anything we wanted to keep frozen. The other esky ten had small quantities that we would top up from the other full. Fo r drinks we would just take a warm can and sit in in the dry ice, constantly turning it for about 30 secs and voila cold cans. Its great stuff but you have to try it out and work out the best way to use it befre you go away or else you will end up with frozen stuff

EVAKOOL recomend NOT using dry isem it perishes the ice boxes (To Cold?)

i used an 8 day block at fraser of xmas and new years, the lady i got the ice from said that the less oxygen that is in there the longer it will stay cold, we put party ice in aswell and it froze nearlly everything our esky is a 110L EvaKool Make sure you put something under the ice aswell, it made the bottom or our esky bubble up, only 3 weeks old too .

I used to get it in pellets as it was easier to manage that way

Sounds like experimentation is the only answer.
Or a fridge and dual battery, I think the missus would shoot me but

Specially since I am gunna sneak in a snorkel befor the end of next week
I reckon I will get away with it for all of 30 seconds from the time I bring it home. Not gunna miss Balfour track for want of a snorkel though

Thanks guys

Where do u buy dry ice from ?

BOC gas n gear stores. Dunno bout newhere else

most ice works sell it some u have to pre order

I have a coleman cooler of about 80 to 100 litres and want to use it for a base camp over xmas for a week at Licola in summer heat. I've found dry ice at BOC in Dandenong for $6 kg but its in pellet form. Is it better to get it in block form and if so how much would you need to last that long and would it be best to use regular ice as well. The sales guy at BOC said you would need to half fill the esky with Dry ice for it to last that long but that sounds like a very expensive exercise. Whats the real story, anyone? Also where can you get Dry Ice on block form.

Supagas in Dandy do it in blocks...
we used 3-4 blocks across the bottom of our esky, with a bag of normal ice over the top, and it lasted 3-4 days, in 30 - 35 degree weather.

Was that just a big esky or was it one of those more serious ice boxes?

if you are worried about your esky buggering up, you could always go the foam option, depending on how much it will get thrown around. im sure you would be able to get ahold of a big enough foam (polystyrene) box to fit a fair amount of food, just depending on how deep the foam boxes go as to storing anything else you dont want frozen in it. the only downfall about that is proper sealing of the esky.

Now the only problem I have is that I have to buy the stuff on Friday 22nd to leave on Boxing day the Tuesday 26th. If I put the Dry Ice blocks in the Freezer at home it should last for a fair while in there or will it dissappear just as quickly. Any ideas, I dont want to wait until the Wednesday to get the Ice and then go away.
