    Re: Techni Ice Sheets

    So Im not a physicist but the Techni Ice sheets only get as cold as the freezer you freeze them in. Ive found they dont live up to their claimed performance on longevity and they do split. I have some but now use them in a small esky that I take along to BBQs and picnics. I love the 3L fruit juice bottles. Clean out well first and it makes good drinking water when they melt about 4-5 days in my esky.

    I think a 12V or gas freezer would be the ideal choice to keep things frozen for a trip that long. They can be expensive though.
    What would Steve do?

    It's true whatever you freeze at home irrespective of what it is will only ever get as cold as what freezes it, the environment and it's surface area will dictate how fast it thaws.

    I gave up on those techniice sheets and the other styles a fair way back and now use plastic bottles exclusively, total frozen volume matters.

    Re: Techni Ice Sheets

    No doubt theheat and humidity o far north QLD will play a part. Because ONLY frozen items will be in this esky with 15 sheets of techni ice, this will hopefully only be opened once or twice a day. I am hoping that things lastlonger this way.

    Also hoping that somewhere in Capetribulation or even in Cooktown, i can get access to a bait fridge to refreeze the sheets again for the trip back. I might ask my butcher mate in cooktown to use a freezer overnight for that purpose.

    they say 1 sheet per 7 litre space in esky so i reckon 15 sheets in a 100l esky as well as some cold bottles of water and frozen meat packs this will suffice

    Re: Techni Ice Sheets

    go the frozen bottles no mess, more drinking water, cheap as chips,butcher mate will have some ready for ya to swap and go when ya get there, techni is ok over night but they absorb smells and juice and you will be dissapointed.

    Re: Techni Ice Sheets

    waeco 60lt freezer $1200, 230 amp agm battery $800

    will stay at -20 for 8 days with no charge at 35deg with no further charge

    Connect to car/ boat , go forever

    AGM Battery will last 10 yrs, fridge, well never been able to kill it yet

    total cost $2000

    dry ice $45/ trip/ 44 trips or 4 a year over 10 years for same cost

    So if you do it more than 4 times a year then why worry about dry ice, use it as a fridge for weekends as well

    cheers

    cheers

    Re: Techni Ice Sheets

    Just returened from 9 days in Cooktown and surrounding areas. Techni ice kept things frozen for 3 days with minimal use of the eski. Going again this week for a week but will be using a larger eski. This means that it will probably keep things cold but not keep things frozen. I think ice sheets coupled with blocks of ice will do a better job

    cheers

    Re: Techni Ice Sheets

    I prefer the dry ice, but only with plenty of food around it so it doesnt die off quickly - space kills the dry ice. And lock the veg and fruit away from it cause it will gas them up...

    Tehcni ice sheets are ok but a bit of a pain. Nice for that little day trip when you want to cover some stuff to keep fresh. Otherwise bottles, party ice and dry ice and well packed esky.

    Re: Techni Ice Sheets

    Thanks everyone for the posts. I have been looking for a good ice box / esky for ages now. Decided to buy 100 ltr Techni Ice chest and 16 sheets. I usually freeze 3 Ltr bottles rock hard in my deep freeze - they last ages and yes great to drink the water from them as they melt. I also bought techni ice sheets to keep the blocks of water (In the 3ltr bottles) frozen longer. As the Ice melts the plastic bottle allows condensation to build on the outside of the bottle... this is what will damage the techni ice sheets! Keeping them DRY and not wet will stop them expanding and eventually splitting. I like the cliplock bag idea. When I leave home and pack the esky (last thing I do before leaving) the esky is -18deg. This time when I arrive for my 10 day beach bumming holiday, I plan to bury my esky in the sand and keep a thick tarp on the top of it. I have got 15 days out of this technique without the techni ice sheets and without a techni ice esky. Would like to know how KINGKEV got on ?? take care to all readers of my post, and I'm keen to hear your responses and suggestions.
