Ultra low temperatura experience?

[TitanioMan]

Hello to all, I´m new on RE
I´m working on a very interesting project for -60+ °F Blast freezer temperature, have no experience on electronic or this low operation for TXV valves, does any knows about it? I´m considering use EC Emerson model

It would be worth investigating Danfoss electronic TX valves .

They are a complete system by just picking required modules , temp probes etc .
They are commercially available at a commercial price and for refrigeration duty only .
Very reliable

Thanks Ranger1, will do consider, I saw some in operation in NH3 and really like the Danfoss but maybe the size available are big for my needs

Are you trying to design a system or are you working on a manufacturers? This is all we do, that is why I ask. You are talking about a test chamber.
