Graham condenser for the Magic Flute

[olddog]

Just built a Graham condenser for the Magic Flute, this will complete the build of this still. LWTCS was building the same time as I was, but I guess he beat me to posting, anyway here it is.
This is the main 3" body with a control manifold on the water output.

I offset the water input so it would have a swirling action around the coil.

The coil is 3/8" annealed copper, it was easier to wind than I had imagined, I hard soldered a 90 degree to each end to align the tails central. Hard solder is a pig to work with when you only have a Mapp torch, probably easier with oxy.

Here's the condenser mounted to the column.

A bit more work to do yet but I have had enough for the day, I have to hard plumb lines in from the manifold valve to the dephlagmater, and run the water return lines. Also I have to finish the spirit takeoff and fit a parrot to it.

OD, you are a copper magician!!! Looking good. MM

Looks real good OldDog. You produce some of the finest copper work out there. Keep it up.

OD, why don't you move to NZ so I can try to get you making stuff for me? It's just across the ditch.... legal.... do it....

[LWTCS]

Hey OD.

Give us a bit more narrative about your cooling management (please).

Give us a bit more narrative about your cooling management (please).

Nothing too complicated, just two valves on the output of the graham condenser, one to control the flow to the dephlagmater, the other to control the throughput of the graham condenser.
I will be doing the rest of the plumbing today, I will post a pic when done.

Will you have fresh (Cool ) water to the graham and fresh water to the dephlag?

BTW, I like the way you off set your nipples. Wish I had done that.
I was going to pack my dephlag and Graham with a bit of mesh to create turbulance.
But just punked out as I figgered the 4" jacket would make up for the lack of engineering.

BTW, the phase II part of the tower is a heavy ass bastard. Giving me second thoughts.

One could bludgeon One's enemies with them fittings.

[olddog]

No the output from the graham will feed the dephlagmater. I could do it the other way but I would then need a dual system, pumps etc.

I could not get the dog dish to put the tower into 100% reflux with out a fresh batch of cool water.
So I planned on plumbing the new dephlag similarly.

[olddog]

If I increase the flow to the dephlag to achieve 100% reflux, nothing will be coming out of the graham, as I will be able to divert all of the graham cooling output to the dephlag. I had this type of setup in my first trial using plastic garden reticulation bits and pieces, the system I am using on the Graham condenser is just a refinement with better control valves mounted on the condenser for better access.

Good call.
Recon I'll plumb the fresh water to the dephlag first.
The graham should have plenty of knock down power with a bit of the recycled water and the vapor temp will be greatly reduced because of the dephlag.

[olddog]

I would personnally go the other way round as the output cooling from the graham will be cool when achieving 100% reflux as the graham will be in passive mode not knocking down anything , whereas the output from the dephlag is quite hot.
