shotgun product condensor for the 5"

[jimmyjames1981]

I'm looking for some advice on my shotgun condenser for my 5"flute flute I'm building, I have a huge surplus of 1/2"pipe so that's what I will be using for the internal tubes and the external will be 3", any advice on how many tubes and how long I should make it? Better too big than too small

On this one bigger is better. I dictate size according to your take off space and parrot.

+1 on bigger is better for final condenser, i figure ya can fit 12 in there with no problem, dont see any reason with that much tubeing to go much longer than 12/14 inches, put the cooling to it and run like hell wont have it!

Holly crap 12 1/2" tubes in a 3" pipe. And I was having problems with 5 in mine.

I can't say as to how much I can really throw at mine. 2700 watts is the most I have at this point. But it knocks down every bit of it. With just a trickle of water. I think you should have a good balance of water mass and number of tubes.

To little water mass with to many tubes you need a ton of water flow. It can handle a ton of vapors but knocking them all down is hampered by how much water flow you have. And flow can be hampered by having to many tubes in the path. The water needs to flow around all of them easily or you will have hot spots.

To much water mass and not many tubes not very much water flow is needed. But it can't handle as much vapors.

When I originally designed mine I had plans to use 9 1/2" tubes 11" long. The shell is 16" long with a gin basket at the inlet end. They will fit if you have a good drill to get the plates drilled right. I couldn't at the time. So I replaced 4 of the tubes with 3/8" tubes. But I think 8 or 9 1/2" tubes 12" to 14" long would work out good. But remember. That sucker will be heavy when its full of water. Hell mines heavy without the water.

i have tons of water flow, im not recirculating and am on a well

This all seems reasonable to me. One thing that I haven't noticed being documented anywhere though is product temperature. Expecially in the 4.5kW to 6kW range. Part of the function of the product condenser is also to cool the product - and this requires contact time with a cold surface, hence a slightly longer condenser - possibly 14" to 24" , I don't know.

Can any of you product shotgun condenser users out there comment on power levels / vapour tube length / product temperature. This might not be a big issue as there are other options - jacketed parrots for example - but I am curious to hear what practical results have been found.

Myles,, my shotgun is 5 3/8 tubes in a 2", it is 14" long (cooling contact) my product can run as cold as 55f all the way up to vapor comming out the parrot. I have a MK5500 controler with a 5500 watt element in a 15 gal keg set up on 240. I do how ever have constant flow of cold water being as I run off a well.
Is this what you are looking for?

2700w 3" outer shell with 5, 1/2"x11" and 3, 3/8"x11" tubes. Tap water between 50 and 60 deg f with a trickle of flow through the shotgun. Product output is 70 deg constant and long as I have any water flow through it.

Do we have any formula for analyzing this design. I just drew a 3" with 12 1/2" circles. In most areas there is at least .25 inches of space between pipes with the inner pipes at over 1/8". I am sure you can rearrange it to get more flow between each pipe if you worked at it a bit more. See drawing below.

Bushman keep in mind 1/2" copper pipe has an OD of 5/8".

Oops I new that but I guess I am still 3 hours off after getting home from Hawaii!

Oh sucks to be you. Glad you made it home safe.
