Reflux Coil
Posted: Fri Jun 17, 2022 9:34 am
Morning all,
I have been looking at different Ideas to adapt my still head to enable me to reflux. As you would all know, a common component between many designs (Boka/CCVM/VM) is a coil reflux condenser. I have read many threads and guides on winding coils.
I then stumbled across this guy in QLD on ebay selling double helixes for a reasonable price. This is considering a roll of 6mm (1/4") annealed copper is not cheap. Cheapest AUS supplier I have found is $55 for 5m delivered. On the other hand, these coils are $68 delivered, I think this is pretty good.

Anyone have any thoughts?
While I'm here, I may as well also ask. For a modular VM setup. Would the 5Star SS 1/2 "BSP gate valve be too restrictive. The plan would be to grab 2 of the 1/2"BSP - 2" ferrule, one for either side, then I can clamp it straight in.
Thinking I could take my 5Star pot, Replace the 1st elbow with a Tee > drop in the horizontal SS Gate with 2" triclamps > elbow off to the PC. I know Ill also need to extend the column and get a small riser to house the coil above the tee. This seems like a decent way to transition to a reflux column.
I could go a similar route without the valve and use it as a CCVM? I think I prefer the idea of a more methodical approach of a valve, rather than raising the coil an imprecise amount.
Thanks all.
