1. Before pumping or draining hot wort through your heat exchanger turn the cooling water on to the maximum flow rate which will purge all air from the water side of the exchanger Slowly increase the hot wort flow rate until you reach the desired outlet temperature If using the ThruMometer in line thermometer and you never see a change in color on the thermometer elements carefully touch the side of the ThruMometer and determine if the temperature is above 88 F or below 58 F If above 88 F slow down the beer flow rate If below 58 F increase the wort flow rate If it is still too cold slow down the water flow rate leaving the wort flow rate at maximum Notes for Southern Climates Brewers in southern climates have a particular challenge chilling wort due to the elevated ground water temperature Cooling water temperatures can exceed 80 F in the summer making chilling wort to the ideal temperature 68 F impossible However the incredible cooling capacity and efficiency of the Therminator chiller will allow the wort to be chilled much closer to the ground water temp at a faster rate and using less water than any chiller on the market Obviously wort flow rate and wort outlet temperature are trade offs A good rule of thumb assuming 5gpm of water flow is that the Therminator will chill about 3 5 F above the cooling water temperature at moderate wort flow rates about 4 1gpm and about 10 F above the cooling water tempera2. 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 Therminator Performance Data 1 040 S G 68 F Wort Outlet Temp LL Q E i o d je O 1 0 1 5 2 55 i olerance Wort Flow gpm 0 2 gpm 2F 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 6 Example If you have 58F cooling water and 5 GPM
