One very important next step is connecting all of our tanks to the glycol system. This will provide chilled water for the fan coil in the walk in cooler, and chilled water for controlling the temperature of fermenting beer as well as providing cooling for serving and conditioning tanks.
The glycol system starts with the chiller, located outside, then heads inside to a reservoir and pump. The glycol is then pumped around to each tank, starting with a fan coil in the walk in cooler. From each supplied tank, there is also a return that needs to be plumbed back to the chiller outside. It is called a reverse return, where the first tank supplied becomes the last tank to send glycol back to the chiller. This process took a little head scratching, but once we wrapped our head around the layout and pipe material and sizing, we think we are well on our way having an economical cooling system!
To finalize the glycol system, we'll need to acquire solenoids for each tank jacket with associated temperature controllers. This will be a pricey endeavor, but this particular equipment will be able to be used at the brew pub once we move the tanks over there.
Next up, connecting our CO2 system to all the tanks! The fun never stops...

| We chose copper for the manifolds. In this case we cut this manifold to yield 3 manifolds of 4 ports each |
 |
| Doing a bit of layout to make sure we have all the right pieces |
 |
| Dry-fitting the supply and return manifold to the layering tanks |
 |
| This is where the supply and return meet the big return to the chiller. There will be an array of gauges and a balancing valve to make sure system pressure is in check |
 |
| Our pet supply and returns, soon to be insulated |
