CellarPro 1800 Duct HOOD (Hot Side) with Inline Fan #7409

I've built these refrigerated closets before, but on this one I built I was not sure if I needed the duct hood since I had open a large open space for the back of the unit. I ordered, but did not install the hood at first. But, after the chiller was running for a about an hour or so the large closet the chiller was venting too had risen abut 15 degrees from "normal". That was too hot and the door to that closet would have to be left open most of the time. I attached the hood and let the intake draw from the closet and I vented the "hot" side to a large semi-conditioned air space. What a difference it made. The closet actually got cooler since it was pulling in more fresh air and exhausting the hot air to the other conditioned space. The fan was not a bother since most of its "noise" was venting to the conditioned space. I'm glad I bought the hood as a "just in case". I needed it.
