"In their opinion the plate/dimple jacket type tanks will restrict the flow too much to use glycol effectively"
Dimple jackets are the standard for brewing tanks, however 15psi is standard pressure for them. If the dairy tanks are not pressure rated then a coil (copper tube?) would be best.
Just thought- a tube next to a flat surface wil have only 5% or less surface contact. Picture it: ' ol ' . It would be good to have a machine shop with a tube bender flatten them out.
