This is a small gear motor with the output shaft pointing down. This is without another part - the s/s "skin" to protect the wort from airborn nasties.
Motor turns at 290 rpm. Had a guy in the shop fabricate the impellers on the s/s shaft.
I am rethinking to have it all one part. A cover for the brew pot that holds the mixer, instead of a two piece device.
I get from boiling down to 10 degrees over what my supply water is in less than 10 minutes.
Then, a prechiller brings me down under 70 F in 20 minutes.
