Hi
I am hoping someone can shed some light.
When in reflux mode, my reflux condensor is knocking everything down, but it seems as if some vapour is able to past the product condensor without being knocked down.
the product condensor is a 2" shotgun condensor and is 1 m long.
The condensor and cooling water are cold to touch. Water is 20 C.
Can anybody suggest why I may be getting this vapour past the condensor. same still in stripping mode does not have the same problem?
Regards

Re: 2" CCVM condensor issues
A 500mm 2 inch shotgun should knock down heaps, a 1 metre 2 inch is massive... boiler size and power input will help with solutions. Post a few more details on power and volume as well as how you have your inlet and outlet set up for the water supply and you should get some joy

Sporacle
Sorry column is a meter the condenser is 500MM, but as you say should be plenty;
Bioler is 50l (40l charge on this run).
Column is 1m and packed with copper mesh.
Cooling hose is a 12mm pump and as mentioned the water is cold 20C to the touch.
Reflux condensor and product condensor water are separate supply.
The head temp at the line arm, is 70C

Re: 2" CCVM condensor issues
Is the vapor that's escaping the condenser hot or cold?
If it's cold, then it's what I call condenser fog.
The CO2 from the boiler is getting chilled by the condenser.
When the cold CO2 hits moist air, it causes it to fog.

Shady
I think you are right, does look a little like fog and yes It is cold, does not condense on a mirror.
I was confused as the condenser is cold and if it were vapours sure that condensor would be hot or at least warm
Thanks

Re: 2" CCVM condensor issues
Picture this.
The boiler is full of carbonated beer and your heating it up.
That's a lot of CO2 heading out the door.
No alcohol is getting past the dephleg but the CO2 is.
The still was in 100% reflux, so the product condenser was cold.
If the CO2 get's chilled below the dew point of the air.
Fog happens. Kinda like dry-ice.
