Summer is here and temperatures are soaring throughout the country. If you are sweating up a storm while working on your dairy, imagine how your cows feel. What methods are you using to mitigate the summer heat and its effects on your herd?

Cows in virtually every state require cooling during the summer months. We all know the consequences of heat stress – losses in milk production, reproductive performance and sometimes death.
As dairies are getting larger and larger, the number of fans needed to cool cows increases proportionately. Energy costs to operate these fans increase every year as well. It's important that fans be maintained properly in order to operate as efficiently as possible.
A key component of any dairy fan is the bearing. Large panel fans used to cool cows have been designed with flange bearings with grease zerks that require manual greasing once or twice a year. This often does not get done and consequently fans either perform inefficiently or wear out quickly.
A new product innovation of the Agriaire Powerfan is a completely sealed bearing that requires no manual greasing. This is welcomed news to dairy operations that often overlook the importance of keeping fan bearings properly greased for optimum performance.

Big Ass Fans

Large-diameter, low-speed fans provide uniform air movement to create natural dairy housing in an amazingly quiet, energy-efficient and cost-effective way.
The benefit of air movement to effectively improve herd comfort and maintain milk production is well documented; specifically, air movement helps transition milk cows year-round despite seasonal changes and provides optimal cooling during the hottest months.
New innovations take the concept several steps further, perfecting the science of air movement and more durable air movement systems.
The new iteration features a unique, new patented airfoil system that combines patented airfoils and winglets with patent-pending AirFence technology to increase overall coverage area by 28 percent. The fan has undergone thorough testing and durability improvements, resulting in an unprecedented full 15-year warranty.
Combining air movement with the atomized mist lowers the actual temperature by up to 30 degrees Fahrenheit without getting facilities, bedding or employees wet.
We feel that the design of the physical inlet, the controller that operates the complete system and the improvement of the knowledge of application is paramount to the furthering environment of the dairy cow. These inlets range from various types of curtain systems, side wall inlets of all shapes and sizes, ceiling inlets, motorized shutters and we also have available air curtains with unique air pockets made in a triangular construction.
The control system is iPod-based and adjusts the misting fan’s output and direction with ambient conditions, which provides maximum day and night cow cooling. Schaefer provides two motor choices based on your application – one-half horsepower or three-quarter horsepower fans – in order to deliver the best return on investment (ROI) for your dairy.
Conclusions from one of these white papers state that the FlipFan system, equipped with adjustable fans, is more effective at lowering core body temperature, increasing resting time, and minimizing heat stress of lactating dairy cows in a semi-arid climate compared to standard non-adjustable cooling systems.
In order to achieve the greatest benefit from this system, it is recommended that it be operated continuously during periods of heat stress, assuming an adequate source of water is available.
All models have been BioEnvironmental and Structural Systems (BESS) lab-tested for cubic feet per minute (CFM) and CFM/Watts to ensure proper application and the best ROI for the dairy. Multiple configurations of motors and blades are available to fit the exact configuration for each dairy. PD
