Ice Machines

If you are familiar with A/C equipment, maybe you know…?
How do ice machines avoid having the evaporator’s coil frozen up with undesired ice from frozen condensate developing on the coil?
If I have the wrong mental picture about such equipment, please feel free to set me straight!
Thanks

Ice machines cool the water directly. They do not cool any intermediate air and so have no air heated coil where humidity could condensate.
