I combine Cooling & Whirlpool in the same step. After I Steep in the Kettle, I draw off the bottom of the Kettle, through the Drain Valve, into the Circ Pump & into my Immersion Coil in a 25 Gallon galvanized Tub full of ice water. From there back to the bottom of the Kettle with a Dip Tube in the bottom of the Kettle. The return from the Coil spins the Wort to Whirlpool leaving the Trub in the center. I have to restock the ice once during the Whirlpool/Cooling process. I'm able to cool from 190 F to 68 F in about 30 Min. Accomplishing both at the same time.
Works for me.
