This plate chiller is used for my 10 gallon brewing system. I have a couple of pumps I use to run water and wort through the chiller. It gets 10+ gallons of boiling wort to under 100 degrees in about 15 or 20 mins, then takes another 10 or 15 to get under 80, mostly due to hot TX water and not having enough ice on hand. But overall the chiller does a decent job of transferring the heat. I just wish the water ports were fitted for garden hose. Not a big deal, I just hooked up some quick disconnects and bought an adapter for my garden hose. Also, I_ like the brackets to be a little longer as they seem to bend slightly trying to cinch them down- again though nbd.
