We found a freezer unit out of a old grocery store on craigslist.. It is very similiar to a cool calf, but this one has 6inch walls and ceiling. Ours is a 20x30 and I wish it was bigger.2 pens and a clipping area and a rinse area inside. Once the concrete is cooled down it doesn't take much to cool even with 3 fats. The more area, the eaiser to keep cool once it is cooled. The cooler is turned on earley around sunrise, without cattle inside. In 30 min., the room is at the temp we want and the cattle come in. In our other barn we had a 12x16 room and it took alot more to keep cool. The compressor is a 3 hp and we have 2 condensors inside that mount to the ceiling. We bought this unit from Barr refridgeration in Appleton, Wi. They were great to work with. Thay wanted to know everything from the size of the room, the body temp of each animal, how many and what type of lights, size of door, and how often the door would open and close. They were way, way, way cheaper than the coolcalf. But the cool calf has some whistles that we did not need that others might like. We also use this as a heat room in the winter, we keep it at 40-50 all winter. This is the place we wash and dry when its freezing. the cattle love it, open the doors in the morning in the summer, the steers walk to thier pens without chasing them in. Yup, just like dairy cows to get milked.
