I have a VM still 1 3/4" with SS scrubbers to within 4" of the take off. There is a good 1.25 meters of scrubbers.
The still was not a problem till I changed scrubbers so unsure what I have done wrong !!!
I have a voltage controlled 2000w (220v) element on a 30 litre boiler. The column is flooding even on 850w of heating.
The cooling water is not hot so it seems an overload of vapour rather than a cooling issue.
The scrubbers seem packed correctly, but I guess they can't be!!!
Any suggestions are really welcome.
