capillary tube question on glycol cooler how long does it need to be?

[born2dive9702]

Hello everyone
I am hoping someone smarter than me may be able to help me out here.

I have built a glycol cooler for my ice tower, similar to this one https://www.acbeverage.com/catalog/pro-line-13-hp-air-75

It has a 1/3hp danfoss compressor, using 134a Freon
The condenser is a 1/2 hp condenser with variable speed fan
the system is pumping 50/50 glycol water and a 3 gallon tank and is pumping about 4 gallons thru the lines.
it is using about 90' of 3/8 copper tube for the evaporator.

So what size and what length cap tube should I be using. I am trying to get the glycol down to -10'F or 23'c

Now I know that the unit in the above mentioned website says to use 112" of .054 cap tube, but that unit is using a matched 1/3hp condenser vs my unit is using a 1/3hp compressor with a 1/2hp condenser

Also I don't believe that this unit will get the glycol down to -10F so what size cap tube do I need to use.

Please let me know and Thank you for your help
