Most of the large grows use Quest. In your case a quest 105, but from what I know of dehues they do not have a vent for the heat but the better ones do have a drain you can plumb to run the water out of the grow room.
Quest is exactly what I have been seeing in the larger grow operations on that youtube series I think was cannacribs. I distinctly remember seeing the Quest in one of the AZ grow ops, he had several for I'm not sure how many square feet but in the four figures for sure.

Also you can check out Active Air they offer some smaller units that are good as well. 70 pint and 110 pint. Depending on your grow you may need a larger unit.
