I am using this setup to maintain Mash temp.

Pump 1 circulates hot water from the HLT through one side of the Counter Flow Chiller.
Pump 2 circulates wort from the Mash Tun through the other side of the Counter Flow Chiller.

I was able to maintain the Mash temp within 2 degrees of target over a 90 minute mash.

This is completely manual setup. I found it best to keep the HLT water temp at about 180 degrees. Start Pump 1 shortly before you need to start Pump 2. This allows the Counter Flow to heat up prior to pumping the wort through it.

We are going to start with the Grundy tanks as our Fermenters. Then as we need to expand, we will purchase Unitank Conicals and phase out the Grundy tanks. The Grundy will become Bright/Serving Tanks for the tasting room.

We are going to use this tank as a Mash Tun. It is a 200 Gallon Grundy with the top cut off. There is a screen in the bottom already. It also has a port in the side that was used to perform a Whirlpool, not sure if we will use this as we will be performing back-to-back batches to fill up the 6 BBL Fermenter.

This is everything in bags laid out on the floor. It took me about an hour to inventory everything and take pictures.

There are about 66 of the 1.5" TC clamps. We should not need to buy another clamp for a long time, even when we get a full size production brewery.

We need these for the fittings on the HLT and Boil Kettle

We may be able to use later, but most everything currently is 1.5" TC
