Can I connect 2 G5's to 1 mt69 or do I need 2 mt69's?
Anybody have pics of this setup?
I would use two or better yet, 50' of 3/8" stainless intead.

A Promax 6000 can't stay with a Gast either, without help from an interim heat exchanger.
The pressure in the interim tank rises above 50 psi without it.
The interim heat exchanger dropped the pressure on the discharge side of the Promax about ~100 psi.
Part of the reason that the pressure rises that high in the interim tank, is that after long running, it exits the Gast hot, so in our current build, we have three heat exchanger coils in the same housing, and plan a counter flow heat exchanger at points of butane injection.
The central coil in the main heat exchanger is 50' of 3/8" stainless coil and the two outer heat exchangers are 20' of 3/8" stainless tubing. All plumbing connections enter from the side and exit from the bottom, so as to render the coils self draining.
The central coil is set up for liquid N2 injection, and the discharge from that line goes to 40' of 3/8" of stainless coil in the storage tank bath, before exiting to atmosphere.
The two outer 20' coils are for the diaphram pump and the recovery pumps discharge to their respective tanks, so as to lower pressures both places.
That leaves the center open for dry ice, if liquid N2 or liquid CO2 are not available to inject through the heat exchanger coil.
The reason for using a counter flow heat exchanger for the butane injection, is to keep the butane liquid and easy to pump at all location except the columns, where we want it subzero on demand.
Our counter flow exchanger will discharge into the storage cooling coil to get maxim refrigerant effects.
We've purchased or wrapped the coils and have the stainless shell drilled and ready for the welder if ya'll wanted to view it before it goes to him.
Photos are always appreciated. It seems simple enough though. What's your flow rate on that LN2? Seems like you would go through a lot.
Does anyone know if we can use the Yellowjacket XLT recovery pump? My concern is that it shuts off under 13" Hg....... I know this protects the pump, but won't work for our application properly, will it?
Anybody else have pics of a dual recovery pump setup?
Here is a triple installed until electrical could be run for the compressor. They hook common 1 1/2" intake and discharge plenums, made of sanitary spools, using 1/2" lines.
Right now I'm waiting on my second tr21and am planning to use one of them for warm vapor assist during column recovery. I plan on pushing the warm vapor coming off of one of the pumps down through the column to the pot and recovered by the other pump and then valved off to finishing recovering the column separately after it has gotten enough heat from the pump. Has anyone tried this and if so what kind of improvement in recovery times did you see?
I believe the tr21 pumps warm liquid not vapor.
