Hey all.

I need some help. Right now, I have spec'd out a chiller I need for my application. The application is a blow molding dept consisting of 9 blow molding machines. We'll require a 100 ton chiller to accomodate the machinery, give/take because not all run all the time.

How do I go about sizing the storage tank/pump skid? Right now, I have about a 225' stretch of 2" pipe going down the wall of the plant, and then returning to the chiller. There are drops going to each machine on this stretch of piping.

By the looks of it, I have to have a minimum of 267 gpm of flow to all machines if I want to run everything. Pressure needs to be 60 psi min, but I'd like upwards of 80 psi. I'm not sure either what size piping would work for 267 gpm, but am leaning towards 6" to be safe.

Please, any help would be greatly appreciated.

Thanks
