Summary: Cows at Grand View Dairy and D. Kulper Dairy in Arizona were some of the first to experience the FlipFan Dairy Cooling System. The design of the system allows the 36-inch fans to rotate 180 degrees to point outside of a shade structure. It also features control options that allow producers to adjust for time, temperature, humidity, milking and feeding times and, new to the industry, wind speed and direction.

Q: What type of interest have you received? How do you quantify that interest?
A: We have seen significant interest from dairymen and academics. In 2011, we installed a total of eight FlipFan dairy cooling systems in Texas, Arizona, California and Mexico.

ARTICLE

Although the winter months are quickly approaching, it is not too early to start reviewing ways to better manage the factors that could impact your operation’s milk production levels next year, such as cow comfort and cooling.

In the summer of 2010, Schaefer Ventilation Equipment ran a trial of the FlipFan Dairy Cooling System on two Arizona dairies, Grand View Dairy and D. Kuiper Dairy. The trial was established to determine the types of benefits and added improvements this type of cooling system could provide dairies across the southwestern portion of the U.S. during the hot summer months.

“Our decision to go with the FlipFan Dairy Cooling System was partly brought on by my old system being twenty years old and they were stationary fans,” says Darryl Kuiper, owner of D. Kuiper Dairy in Buckeye, Arizona. “We can actually reverse the direction of the mist and cool the cows where they want to lay.”

This cooling system combines 36-inch, high-velocity fans and misting systems with a horizontal rotational mounting structure that allows the fans to “flip” 180 degrees to point outside of the shade structure, which enables nighttime cooling as well.

The following are a few areas in which this system may be able to help on your operation.

Day and night cooling
Throughout the day, the internal temperature of your cows rises. Although daytime cooling is important to controlling this temperature rise, it will not eliminate it. Even with daytime cooling, the temperature and heat stress of your cows rise until they reach their peak after the evening digestion.

The most critical time for your cows to recover from the heat stress that accumulates during the day is at night, after sunset. However, if nighttime temperatures are insufficiently low, your cows will not fully recover before the next day’s heat accumulation begins, which could cause a rapid decline in the cows’ milk production and conception rates.

These fans can be set to reposition into the loafing pen where the cows spend the night. This nighttime cooling will allow the cows to fully recover before the next day’s heat-stress accumulation begins, increasing milk production and conception.

Control options
The system offers control options that range from simple manual controls to programmable logic controllers (PLCs) that can adjust the system for time, temperature, humidity, milking and feeding times as well as wind speed and direction, a feature that has never been offered before by any cooling system.

When the cows are being milked or whenever they are not needed, the system can simply be adjusted to face a vertical position, which will also help keep the fans out of the way of tractors and other machinery.

Affordability
The FlipFan Dairy Cooling System is half the capital cost of competitive cooling systems, starting at $350 per cow once installed for large dairies.

“When you are looking at any pieces of equipment that you are going to buy, you want the best value and the best equipment to do the job,” says Nick Vanderwey, one of the partners at Grand View Dairy. “This fan system is the best cooling and the best cooling per dollar that you are going to spend.”

Other factors that Vanderwey and Kuiper acknowledge are the system’s ease of installation and low-maintenance requirements.

If you are deciding whether to invest in a new ventilation system on your operation, consider how cost-effective your current system is and whether or not your summer milk production and conception rates have room for improvement. If you think they do, then this technology may be worth looking at.

Although this FlipFan Dairy Cooling System is specially targeted for the southwestern region of the U.S., Schaefer will also continue to provide innovative ventilation solutions designed for your geographical region.
