Glycol chiller sizing help

[Hop Farmer]

We're adding two new 15 bbl unitanks and need to get a second chiller for these tanks. We currently have a 1/2 HP chiller running our 7 bbl tanks and could potentially get a chiller big enough to handle our three existinf 7 bbl tanks plus the two new 15 bbl tanks. Any sizing recommendations for:

1) Two 15 bbl tanks (or)
2) Two 15s plus three 7 bbl tanks?

Nothing else (HEX, coolers, etc.) would be running off this.

Thanks!

A calculator I have gives me the following

15 US brl (1760 litres) to cool at 1 deg C / hr requires about 2.2 kwh

Top heat cooling required = approx. 0.4434 kwh assuming 48 deg SG (12 deg P) over 60 hours)

1 kwh = approx. 1.341 HPh

So now you can mix and match the volumes at top heat and cooling to determine your peak loading. These values don't take into account any heat gain or loss due to (lack of) thermal insulation.

Great, thanks for the help.

Hey Hop Farmer,

I'm up in MA working on getting a 6.5 BBL system. I am looking to run 2-3 7 bbl unitanks. Could you tell me more about your current 1/2 HP chiller?
