Yeah, the ice is a problem, I know. You'd have to setup your pump in such a way that it circulates the coolant, so that it doesn't freeze. It should be perfect for a dehumidifier, that's the way I'm headed.
I don't know of any brands that don't have the additives, but I know that they should be the cheapest kind, so as long as the contents are indicated on the label, then that's what you need to be looking for. I haven't had any luck here yet, but I haven't been really looking either.
