Or out of ice over the cold plate flash chiller. Warm soda is flat soda.
Carbonator pumps put out way more than 100 psi. That's the CO2 pressure in a carbonator tank that the pump must overcome to inject tap water, which is why you need a pump to start with (tap water being way less than 100 psi).
I expect you'd need a bypass regulator, since the pump must need flow to stay cool, so a static (?) regulator wouldn't suit.
Or how about this: you could get a whole McCann's carbonator unit (pump, stainless pressure vessel, level switch) for about $200 or less on eBay, and pressurize it with 50 psi air instead of CO2, and then you'd have a stable 50 psi water out. And with a CO2 tank you could make soda after work.
"Fountain" soda - aka the type in a cardboard 'milk like' container is without water and soda. That is flat. It is syrup. If a baby has colic or gas on the stomach - get some from the fountain people - just a pint or less - and put it in a baby bottle with water. Make it just like to drink - the baby will drink it and the soda will absorb the gas. Been there done it. Grew up in a family of 5 kids.
I used to have a cold plate - big chunk of Al - that is for sure. And a Green high pressure bottle. Gave them away - soon after they were dumped on my driveway. Some kids got it somewhere - and I bet it was hot. My kid was 6 months old so it wasn't him or his. :-)
The one I had from COKE - had a one way value on the gas tank - I suppose that prevents problems.
I call flat coke that sits in a glass or out of a can that falls on the floor and foams all over. Coke is coke - coffee is coffee - as long as it has water in it
- it is just fine to me.

This is the best idea. Forget the heat exchanger. Bolt it on the top of a reservoir for the return hose/pump intake, pressurize to desired flow rate and go welding.
Having asked my TIG torch maker their reponse was you need a pump capable of delivering IIRC 60psi in order to get the flow through the small passage in the torch head. The pump has to be able to do that without having issues itself also.
Go to Lowes or a good hardware store and you can get 2" hose pumps. Everything from small to large. Use a sump pump - likes to run dry and turns off. Or a pond pump - not a tiny pump. I have one that shoots a stream out of the end of a 150' hose and I use it to dump out ponds that the rain fills a garden a foot or so full of water. I put in the feeder hose (regular hose) and plug it in.
So figure the gallon/min and plan on metric conversions.
If you're going to cheap out on the pump protecting your expensive TIG torch, at least invest in the fuse link setup the CK Worldwide folks sell that should save your torch and torch cable when your $30 special pump fails.
Here! Hear! My fusible link in the TIG plumbing has saved my butt a couple times. Easy to replace, saved the torch leads, and I didn't have to take the ferry to the mainland in order to buy parts. Eric
