power vs diameter

Thought i would post this here as to not spin the other thread of topic :-D

The build in question is not located on this forum.
That said, there are plenty of great VM designs here for you to work from, a VM is a simple still, no need to overcomplicate it.



Ok i see. Leaves me wondering though with my 2" T500. Its 59cm tall (including where the condenser is) and has an element of 2000W.
I find it runs very different on single runs vs low wines with more joules released from water vapor than the higher volume of ethanol joules in a low wines wash. Maybe the T500 should have a standard power controller to stop smearing or over powering? I sometimes wonder if 2kW is too much on low wines with the T500 :think:

2000w is probably too much, I can run my 4" bubbler with 4 plates on 2400w no issue

I think its so high due to reducing heat up time and most consumers who buy the T500 (no offense) want something that runs fast

I have 4800w of power for my 4" now and I can easily flood it, next upgrade is some more plates and a packed section to see if I can reduce that, otherwise I just unplug one element at temp or throttle the power back (2800-3000w)

I have heard that VM columns can't be flooded and that you just increase diameter to increase flow rates, height increase for quality?

Correct me if I am wrong

Any still can be flooded in the right conditions.

As for VM it can be flooded, if it was flooded at a certain power input increasing diameter would help solve it.
