I'm not familiar with any that won't freeze in low temperatures. Long before freezing air temps. The good news is that freezing air temps won't hold much moisture in the first place.
The self regenerating desiccant types will work down to about 30F. Compressor and pelletier types stop working below 50F or so due to freezing. I started out with a Mermaid AIr compressor type, but I have now replaced it with the EcoSeb desiccant type. The Mermaid Air is sitting on the shelf in my garage.
The dessicant type has the side benefit of putting out about 100W of heat (required as part of the self-regeneration process), which is good in the winter. I have the same type as Wakefield posted above, and it works well. It weighs about 10 lbs, so it is easy to move around and stow.
I started off just letting it drain into the bilge and the bilge pump handle it, but now I bolted a mini-condensate pump to the side of it, and let it pump overboard directly through a drain.
Unfortunately, EcoSeb has discontinued the model I have, which has simple analog type controls, which will always restart following a power outage. Their "improved" model has electronic controls, and I suspect those won't automatically power back on.
pelletier = 0.5 pints/day (too little)
desiccant = 15 pints/day (just right)
compressor = 50-70 pints/day (more than needed on a mid sized boat)
