Hi,
I am finishing up construction of a 50 Foot Couterflow
chiller. Now I have a few questions about putting it
into use:
1. Would PBW and Star San be the preferred methods for
cleaning and sanitizing the counter flow chiller after
use and before use? Any point in allowing boiling wort
to sit in there for 10 minutes prioir to commencing
chilling?
2. Would it be necessary to use a pump to pull the hot
wort through the chiller in a timely manner? It seems
like it would take awhile for the wort to wind its way
through the 50 feet of tubing.
3. If using a pump, I assume that the flow would have
to be throttled back in order for the wort to come out
at the correct temp.
Any other tips or recommendations are always
apprecieted.
Cheers
WH

Will,
If the chiiler has a copper tube that the sanitizer will contact I
wouldn't use Star San. It attacks soft metals - take a small piece of
copper and place it in Star San for a while and it will get very shiny
and eventually even red.
I use boiling water to sanitize my chiller. I recirculate boiling
water through it wile boiling the wort. I also pump boiling water
through it after chilling a batch, that helps clean it right away. The
boiling water also takes care of the hoses.
Every few batches I'll pump some hot PBW through it to clean things
real well. The PBW helps clean up the mashtun and kettle as well.
For my system I use gravity to drain hot wort through the chiller into
carboys. That way I have less hose and machinery to worry about
getting sanitary in the path. Since I went to the boiling water
sanitation that really wouldn't be that much of an issue but I have the
hoses setup for the gravity path. Using the gravity method I am less
likely to suck air into the system which could accelerate oxidation of
the hot wort.
Note, I have a March pump that can take boiling temperatures.

The tubing is stainless so no issue there.
Unfortunately, I do not believe I have sufficient
vertifcal clearance to generate adequate gravitational
velocity, as my system is presently configured. It
could be change, but that would aquire some re-design
work. I was going to purchase a March high temp pump
as well, and use it only for pumping sparge water,
sanitizing and chilling wort.
I guess I will do some experimenting with boiling
water after i finfish up putting the chiller together
and see if the gravity method will work.
