I have a 10bbl brewhouse, does anyone have any input on what the proper water flow rate(GPM) should be to chill beer in a reasonable amount of time. I know there are different variables to this question but the Brewery is located on MI so tap water is usually cold and I do not have a glycol chilled section for the plate chiller. Its all H20

The plate heat exchanger (H/E) manufacturer will have the info you need. Your H/E has a delta that it can move temp, calculated by opening size and flow rate and surface area (number of plates). The variable with municipal water is the temp change from summer to winter. We have over a 40 degree swing between the two, we have a H/E to chill city water down with glycol and another that we send the chilled water thru to chill our wort down. The hot water output of the final H/E is recycled back to the HLT. Cheers.Joel Halbleib

Proper water flow rate for a wort chiller
When we design a heat exchanger for wort cooling we try to match the water flow rate closely to the wort flow rate and aim for a 30 minute knockout time.
So for a 10 BBL system you would have a wort flow rate of about 10 GPM and water flow rate of 10 to 11 GPM.
This requires a few extra plates in the design and requires multiple pass flow pattern but it achieves 70 F wort and you get nice hot water (170 - 180 F) that can go straight in to your HLT.
This is one of our heat exchangers, note that there are ports on both ends.

If the heat exchanger you are looking at has all of the connections on one end then you know it is a single pass design and will require a much higher water flow rate.Your CPE Systems Team!
