proper coil length to cool

[roboroo]

I am unsure how long a coil should be to cool room temp (75F) beer effectively down to 38F dispense temp and I'd rather not experiment.

Here's my monkey wrench... I am using a glycol bath similar to the proline glycol power pack. I want to submerge my coil in this reservoir... a bit colder than ice.

Dispense pressures, and therefore carbonation issues, are less of an issue because I am using a bag-in-box type system to dispense.

This is for a permanent commercial installation for countertop dispense of specialty beer.

Any help?

Thanks,
Rob
