Small problem with CFC V2, now on V2.1...
After doing a couple of test batches I quickly realized that although the shorter length will work fine for gravity feed and cool 5 gallons in 15 minutes, when you hook up a march pump to that length of CFC and start pumping 15 gallons through, surprise! Not enough cooling capacity, unless you throttle the March Pump output to the same speed as a gravity feed...what the hell's the point of that! Sooo.....
Today, I doubled the length of the CFC to 32 feet and ran a test...
Incoming hot water from Brew Kettle, 200 F (93 C),
Incoming cold water for cooling ~50 F (10 C)
Set March pump to unthrottled full flow...
Outgoing Cooled Water from Brew Kettle, 55 F (12 C)
Outgoing heated cooling water 100-130 F (38-54 C) depending on throttling of cooling water.
Time to process 14 gallons of Hot water down to below pitch temp, 15 min, 45 sec.
That'll do...
