WHICH COMPRESSOR TO REACH -80C

[freak11]

Hi,
I wanted to know if you know specific COMPRESSOR BRANDS that can be used for waterchilling to reach a temperature of -80C.

thanks.

ANY BRAND THAT DEALS IN ALL CAPS

ANY BRAND THAT DEALS IN ALL CAPS

are there liquid chilling systems from industry readily available that can be bought?

Yeah, don't do the all caps thing, dunno what your thought process is, but it doesn't get you more attention. Well it does, but negative attention.
Almost all compressors can be used to acheive -80C, some much much lower. However I think you'll smile there, and realize now that this is a bit sarcastic. You need to specify a load. Are you cooling a 1mW laser, or a 500W load.
It all depends.
However, to more accurately answer your question.
No, no single compressor is normally used to go that low. Instead a autocascading or cascading system is used. And commercial systems like this are tens of thousands of dollars.

hi, well i found autocascading freezers on ebay for 1000 -700 bucks with a temperature of minus 150.

They might be cascading actually.
However they are not meant for true heat load, and converting them to a phase unit is an incredibly costly enterprise.
