Power Pack Questions

How many towers can be cooled with 1 pump?

Say I have four towers (with four taps each) to cool and the total distance to the fourth tower from the pump is 100'. Can I use one 250' pump with two glycol lines for all four towers? If so how would you set it up? Or do I need one pump for each tower?

Here is a different scenario but related. Lets say that two towers are on the left side of the building and two are on the right side. Both sets of towers are equal distance from the cooler but are on opposite sides of the cooler. All towers are 14 tap and all taps use the same 14 products. Lets say that the furthest tower away from the pump is 100' on both the left and right side of the building. How would you set up a glycol system for this scenario?

I may be answering my own questions by stating the following but Im still confused so here goes....

I am assuming that a python can not be split to go to separate towers. So you would need a separate python run for each tower. Which leads me to the following questions. 1. How many glycol outputs and inputs does a pump have? 2. Can a glycol line be split on the output before it enters 2 or more pythons and then merged back for the input (assuming there is only one in and one out)?

usually it is one tower per pump.

i have seen a system that is similar to this. not quite as long, and each tower had 14 faucets. the products were mirrored on both ends of the bar. the powerpack they use for this system is enormous! they only used one pump per tower and there were 4 in/outputs on the bath. the bath its self was at least 20 gallons and they used the heat output of the compressor as part of the heating for the building! of course, up here in alaska, any help you can get for heating is welcomed and worth it due to the cost of fuel nowadays!

you can split an 8 product trunkline to two 4 product towers as long as you have 4 glycol lines so you have a supply and return for each tower. you dont want to run 1 supply and 1 return through 2 towers in a series.

1.a pump should only have 1 in/output. i dont recall seeing any pumps that have more than that. you can of course have multiple pumps on a powerpack.

2. yes, you can split the line with a Y fitting, but i dont suggest it. powerpacks are designed for a specific load of cooling. overloading the unit by trying to make it cool more glycol faster is a good way to burn it out.

those are just my thoughts... anyone else?
