glycol power pack and a second pump

[Ithaca Bill]

Hi Scott,
I hope all is well with you and you enjoyed New Jersey. Ocean air this time of year is nice. But we don't kid ourselves...

I have began my system design. Thanks to the info I picked up at the class last week I am not sur la merde. None the less, I do have a question.

My two hypothetical system designs call for 50 or 40 faucets delivered via 10 product trunk line. If my maximum distance to tower is 50 feet, I should be able to use MMPP4302 power pack, capable of 250'. When would I need to consider a second pump and motor? I would not be against having some extra cooling capacity for future expansion, evn if it only a few additional lines.

Thanks for your help. I am going to keep track of how many questions I ask (serious) and we can "settle up" in the end!
Thanks

Hi Bill,

Jersey was cold! Workshop there went well. I would go with the extra pump package and split up the runs to the tower. This stategy will allow you to still dispense product if one pump went down. Remember, ten product conduit has two glycol loops and when you specify the power pack use actual length plus half. Actual length is distance between walk in cooler and tower. With 50 faucets / five towers and actual distance possibly 40', this equates to 200' run plus half -100'. Specify a chiller for 300' and have one pump circulate three runs and the other two. You may have to limit yourself to 40 faucets at four locations if you would like to utilize the 250' unit.
