• Remove and sanitize adapter fittings after each use
• Ensure hoses, pump and other drain fittings are properly sanitized before use
• Boiling the exchanger before use will sterilize the unit, but if properly cleaned immediately after use
this is not necessary.
Estimating Performance:
The graph below is used to predict the gallons per minute (gpm) of wort you'll be able to chill from boiling
down to 68
o
F (ideal fermentation start temp) using water from your garden hose as the cooling media.
Wort specific gravities above 1.040 will perform slightly lower than the graph. Specific gravities below
1.040 will perform slightly better than the graph. Note that small changes in inlet cooling water
temperature and flow can have a large impact on the wort outlet temperature and flow.
1) Measure the cooling water flow rate in your brewery using a bucket of known volume and a stopwatch.
Divide the gallons by the minutes (gal/min). Then measure the cooling water temperature using an
accurate digital type thermometer. Record these values. Note: these values will change throughout the
year.
2) Choose either the 5.0 gpm, 3.0 gpm, or 2.0 gpm line that best matches your cooling water flow rate. If
your flow lies between these lines, it is acceptable to interpolate between them.
3) Go to the point on the Y-axis labeled "Cooling Water Temp (F)" to your cooling water temperature
measured in step (1).
4) Draw a horizontal line to intersect the cooling water flow rate line you selected previously (5.0, 3.0, 2.0
gpm) in step (2)
5) Draw a vertical line at the intersection point down to the X-axis labeled "Wort Flow (gpm)” and read the
wort chill flow rate you'll get at your brewery!
