Pint size is usually proportional to cooling capacity.But from most of the dehumidifers I have seen, they have a/c compressor ranging right around 1/2hp.If you're making a direct die system out of this, it will perform very well.If your just making a quick waterchiler it will still work nicely.I would say around -20c liquid temps, maybe lower.
Considering how cheap it is, just buy it and try it.
