Whats the benefit of the side valve right there?

I think technically you wouldnā€™t want it that way, donā€™t hard right angles increase turbulence in a flow? Sounds like it rips anyway according to how well it works for @Hansel, but my understanding is right angles like that arenā€™t recommended.

I know in hvac you want to keep the number of bends to a minimum due to pressure loss. Canā€™t remember the formula off hand.

BUT, arenā€™t people saying that mol sieves arenā€™t as effective in passive systems due to the lack of turbulence? Iā€™ve seen that mentioned before, maybe you do want some right angles just prior to the mol sieve?

Edit : not answering for pupparoo, just chiming in with my crude understanding of things. Plus sometimes you have to have right angles anyway. My setup has some, Iā€™ve tried to keep them to a minimum though.

The benifit is he has an extra port to use for recovery now instead of just a guage

I never heard of that. How would passive or active affect a mol sieve? If the gas passing through has moisture it pulls it. I ran a sieve passive and most people do

I only have seen it mentioned here, I use a mol sieve in passive too.

Can someone smarter than me confirm if this is an issue or not?

I just know the basics and may be incorrect.

Me too curious about that statementā€¦

Molsieves work passive to
You can confirm for your self by weighing them before and after
That turbulence stuff might have some ground but I haven t seen it

I have and I agree but it seems like waxplug has found something better?

Mol sieve on a passive system.

Oh I use a sieve too on my little passively cls, not saying I believe or donā€™t believe that, just have seen the turbulence thing mentioned a couple of times.

And if turbulence (or lack of, in this scenario) is an issue, would a elbow help with that?

Why is the mol sieve jacketed

I heat mine to the same temp as my pot (68f) to help it from freezing. It works better imeā€¦

To help it from freezing?

Itā€™s being used on recovery, so how would it get cold enough to freeze

Iā€™ve noticed my sieve gets pretty cold too, itā€™s due to gas expansion. I think? pV = nRT?

Iā€™m not recovering nearly fast enough. My heat just isnā€™t there. Iā€™m upgrading to a 40gallon hot water tank here soon. Maybe then this will become an issue for me

itā€™s just always been something Iā€™ve done. Iā€™ve run without and this works better. I think GW taught me to. I use a wrap on a 4ā€x12ā€ dryer with 13x, I run 4ā€x24ā€. When I upgrade Iā€™ll just loop my pot fluid thru my jacket. Any maybe a powder column or twoā€¦

I wrap hot rags around it, or just dunk my tiny one in hot water. Either way, it does speed things up a little bit.

I have a tee on the input with a side for my pot recovery and my column recovery. When I want to recharge the dryer I just flush the column from the column recovery side with n2 a few times, pull a vac for a bit, then crank the heat on the jacket for a while. I then turn off the heat and let the vac run full before isolating the dryer, ready to processā€¦
