Re: How cold

Thanks for breakdown, it was worth a thought.
It’s for phone repairs believe it or not. to remove the broken screen quickly you put it face down on a panel that’s at -150 for 20 – 30 seconds and the screen virtually falls off.

Thanks

Re: How cold

I don’t have the 3-5 thousand pounds to spend on the specialised equipment which is why i wanted to see if something could be done here.
R600 gas has a freezing point of -217c so the gas can handle it but what stops it from going colder? is it the amount of gas, the compressor or something else.
for example, if i took the compressor from a large chest freezer and had it fitted to freeze a 1 foot panel would that freeze it lower or is it limited by the compressor? or is it something to do with having a longer capillary tube or maybe smaller evaporator?
