Building an IC69 Heat Exchanger

[GratefulOne]

What is the difference between a mt69 and an ic69? Thanks

MT69 - CPS's cooler for HVAC work
IC69- the DIY design from this thread


Come on! - Please read the basics and try a google search.

Does one work better then the other ?

This is the place of learning, thought all questions were legit!!

This is definitely a place of learning. However, it becomes less effective as a teaching tool if the threads are filled with repetitive information. If a question has been thoroughly answered, then asked again, it wastes the time of those who actually read entire threads.

The ic69 came about because the mt69 was not ideal for our application because of two main problems. One is that the 1/4in mt69 was too small of a diameter which leads to flow restrictions. The other out problem is that it was not self-draining as the in and out lines are at the top.

Getting rid of ice has been a near 2 year quest, with many tries and failures in between. The window shaker chiller was the breakthrough we've been seeking. Now we have an ample supply of flowing 0f fluid to work with. Much neater and less labor intensive than ice.

Well put, sir

Can you not put the ic69 into the same container you use to put your butane supply tank? Just trying to keep it to a limited number of containers, keeping it small !! Thanks

What material do I need to build one for my system? Thanks

Here is a picture inside a self draining tri-core heat exchanger, with one 50 foot coil and two 20' ones. WW wrapped the two 20' coils around the inner strainer from the sea food pot and purchased the 50'.

Can you not connect the OUT from the chiller to the IN of your butane storage tank? Putting the storage tank in the center of the wort chiller in the same container used to cool the butane storage tank? Thanks GW

I havent decided yet, but I think vertically is going to be most effective for the reasons you mentioned.

We are going to use the same coolant loop we use for cooling the discharge cooler. Probably plumb it in series before the discharge cooler so we get the liquid solvent as cold as possible, but we may switch it up depending.

The repurposed window shaker we are using as a redneck chiller supplies all the coolant we need. It keeps our discharge cooler at around 0F - well below the condensing point of isobutane. we are just using a simple submersible mag drive pump normally used for hydroponic systems. It is a 400 GPH model, IIRC. Not sure of real world flow rates, but it definitely doesn't flow that much pumping PG and water (RV antifreeze) around at or below 0F.

Bottom line is it works like a charm, and we seem to be getting faster by the day.

Old engineering principles which say if it works it isn't stupid and the fish trap exists because of the fish.

Good job repurposing the window shaker and finding an affordable circulation pump that tolerates the temperature!

We have a similar project refining butane, which uses a -40C refrigeration plant, and the cost difference between a mag drive pump happy at 0C and one that will tolerate -40C, is breath taking so far.

If anyone knows of a 20 gpm at 100 psi mag drive gear pump source reliably operating at those temperatures and reasonably priced, is invited to share.

On thing that I did discover searching for low temperature coolants, which still have low enough viscosity to pump at -40C, is that 50/50% Methanol and water work very well. Better heat transfer than ethanol, isopropyl, and many of the glycol alternatives, and doesn't turn to gel at that temperature.

What did you use as the through tank fittings that you welded in GW?

You could if you used a larger diameter coil.

1/2" 304SS Sch 40 coupling

 

[Nssknight]

Would a 3/8 coil be big enough?

Whether it would be in theory, it certainly has been big enough in practice, but a 1/2" would give you more surface area.

Vacuum Cold Trap

Vacuum Cold Trap

Are you guys running cold traps on the vacuum intake?

How well are pumps like the CPS VP6D holding up if one is not used?

 

[Gray Wolf]

Never had an issue with the high vacuum pump and don't use a trap or filter.

Why is it important that the ic69 is self draining ? Thanks GW

NssKnight: WHAT THE FUCK? WHY DONT YOU READ FOR YOURSELF? Are you another troll account created by grow nerd just to poke at us? More then one of us have told you all will be revealed alot safer to you if you just take the damn time to READ MAN. I mean CTFO! GW cant hold your hand thru it all bro, gotta cut the cord @ some point and man up, get your feet wet, do diligence.

Your posts are so lame and offer no contribution towards the positive broadcast of our emerging culture to casual onlookers. Think about how someone who knows nothing about cannabis/separation and refinement, coming to our little corner and seeing the type of garbage clogging up our streets that you post. We are already looking gutter enough out the gate, and need no help there.


I hate to be a dick but it must be said. I welcome any feedback.

So, after reading the full 22 pages now is the consensus to have one chiller post refrigerant pump and a second chiller pre-injection with the recovery tank room temp? Currently, I have one 3/8 50 with 3/8 hoses placed post refrig pump. It seems some are going up in size both in hoses and coil dia to 1/2. The second question would be has anyone seen a noticeable difference in recovery times utilizing the larger hoses and/or coil diameter?

It adds back pressure when it fills and can plug if it fills with thick chilled or mushy butane containing water.
