Steven Nisly It is a weakness of all butterfly shutters. There are fans with motorized butterfly shutters which solves the high wind and sealing issues, such as the Skov Blue fan. The doors are not super insulated but they do have an insulation "disk" that winterizes the fan very well. It is also a variable speed fan. As you might expect it is not inexpensive.

Nice information by Dr. Mike Czarick, The potential for evaporative cooling depends on the difference in wet bulb and dry bulb temperatures of the air. Humid air has a high relative humidity, and not as much capability to evaporate moisture. As the relative humidity of the air increases, the performance of the system will decrease, limiting its application in moist climates. Evaporative cooling is ...

The house has been preheated for 36 hours to 92°F. The chicks will be arriving in a few hours and the controller’s six temperature sensors (positioned one foot above the floor) indicate the air temperature is between 91 and 92°F (Figure 2). A thermal image indicates the floor temperature is between 87 and 102°F (Figure 1) There is no measurable ammonia due to the fact that litter ...

Recently a study was conducted on commercial broiler farms examining broiler water usage over the first seven days of a growout. High-accuracy, ultrasonic water meters were installed in twenty-two broiler houses (18, 40' X 500' houses, four 54' X 500' houses) on nine farms. The water meters were capable of accurately measuring water flow rates as low as 0.005 gals/min, which is 50 ...

Getting chicks off to a good start is very important to overall flock performance. At no time does a bird grow faster than during the first week of its life. Over the last week of a 42-day-old flock, a bird’s weight will increase by approximately a third. In contrast, a chick’s weight will typically increase approximately four fold, possibly more, by the time it reaches seven days of a ...

Figure 1 illustrates the amount of water which will evaporate from properly wetted, 15 cm paper evaporative cooling pad system, as a function of outside temperature and relative humidity. The amount of water evaporated is provided in terms of gallons per minute per 100,000 cmh of operating tunnel fan capacity. For example, if a house had 100,000 cmh of tunnel fan capacity and the outside temperatu ...

Figure 1 illustrates the incoming air temperature for a properly wetted, six-inch evaporative cooling pad, while Figure 2 illustrates the predicted incoming relative humidity. The precise amount of cooling, and therefore humidity, produced by any evaporative cooling pad will vary with how throughly a pad is wetted as well as its age. If significant portions of the pad are dry, the cooling produced ...

Though there is a wide range of opinions on the optimal drinking water temperature for young chicks, the fact is farm managers actually have a very limited ability to control the temperature of the water their chicks are drinking because, for all practical purposes, it is determined by house air temperature. If the air temperature is 90°F, the water will be around 90°F. If the air temperat ...
