Best chiller to get to -100 and auto feed system?

Hey again,

Was wondering if anyone could point me in the right direction for best bang for the buck chillers we have a pope spiral condenser cold trap and was looking for a chiller to get the liquid inside the coil to around -90/-100C was thinking maybe LN2 assisted and antifreeze in the coil or any suggestions? Also hate the feed hopper Pope gave us as it has a Z curve and a weird turning valve so looking for one with a straight down connection or a auto feed system that is vacuum assisted for more accurate feed any suggestions I am trying to learn all I can but know I’m asking a lot of questions. Thanks in advance!

Look up various Tri-compressor chillers. Industrial suppliers should have something in that range

Hi,
We can provide a liquid level control and a solenoid valve that will run your old trap, just connect 120l low pressure dewar and go.
