Having a big ceiling fan for your dairy farms

Heat stress abatement on dairy farms is crucial in the summertime. Ceiling fans are used in dairy farms to make fresh air available for milking cows and to cool down their heat. Providing a comfortable environment for high production milking cows, by air circulation or other cooling methods, has been proven to avoid downfall in milk production. In this regard, Qixiang has taken action for the design and production of 5.2m and 7.2m ceiling fans.

Gearless direct drive PMSSM HVLS ceiling fans for dairy farm. For the dairy farms with high humidity and serve environment large open space, the gearless direct drive PMSSM HVLS ceiling fan will be the best solution.

You are lucky to find out the most matured gearless direct drive PMSSM HVLS ceiling fan manufacturer in China with higher technical threshold permanent magnet inner rotor design.

In terms of selections of gearless direct drive PMSSM fans for dairy farms, the follow issues need to be considered: 

1. It should be the gearless direct drive PMSSM HVLS ceiling fan (0.88KW Max. ) instead of gearbox type heavy duty 1.5KW HVLS ceiling fan due to the PM maintenance free factor and super quiet operation.

2. Regarding the PMSSM unit itself, it is essential to have the nature cooling for the motor instead of having extra small fan underneath to do the air cooling. This is concerning the internal structure of permanent magnet, we are having the higher technical threshold inner-rotor design with nature cooling instead of external-rotor design with extra air cooling. Just image if the extra cooling fan is defective, how to protect the motor from over heating during daily operation?

3. Protection Grade IP64, PMSSM unit is a complete enclosure unit with dust and water proof, in cowshed or livestock farms it is fine to use the water gun to do the cleaning of the equipment. Totally hazard free!

4. Various size in the same type of PMSSM motor. The blades diameters vary from 5.2m and 7.2m, much more flexible in application.

Although large HVLS fans are commonly used in industrial sites, in fact, large industrial HVLS fans are also particularly suitable for dairy farms. Large HVLS fans could help solve the problem of ventilation and cooling of dairy farms, thereby increasing the milk production of dairy cows and reducing dairy cow diseases. Actually, the HVLS fan was originally developed for animal husbandry applications. In the last century, American farmers hoped to find a better way to help cows cool and reduce heat stress, as it is known to dairy farmers that if a cow feels comfortable, then it would eat more and produce more milk. By adopting the method of an electric motor equipped with large fan blades, the embryonic form of the HVLS fan appeared. And HVLS fans were gradually widely used in industrial sites.



SOME ADVANTAGES WILL BE REVEALED when HVLS fans are installed on dairy farms.

1.

Cows will feel very comfortable and involved in milk production.

With competitive price and timely delivery, Windmax Power sincerely hope to be your supplier and partner.

As HVLS (high-volume, low-speed) fan has 24ft/7.3m diameter fan blades, it can produce large air volume. While the HVLS fan rotates very slowly, only 54RPM per minute, the wind speed is slow, gentle, soft, and silent. All of these make cows feel comfortable and happy and then eat more, and cows will produce more high-quality milk.

2.

Improve the lifespan of cows.

If the environment is humid, cows can easily get sick. This would lead to a shortened lifespan for dairy cows. After the HVLS fan is installed, with the rotation of the HVLS fan, the fan can evaporate the water vapor in the air, making the dairy farm a little dry. Thereby reducing the growth of bacteria. A clean environment will reduce the number of illnesses in cows, thereby increasing the life span of cows.

3.

HVLS fans can help dairy farmers save on electricity bills.

One 7.3m/24ft diameter HVLS fan could cover square meters. Large industrial HVLS fans cover a large area, with only 1KWH of electricity per hour. At first, dairy farmers will choose to use high-speed fans. The sharp wind of the fans makes dairy cows feel not comfortable. At the same time, one set of small ceiling fans only covers 15 to 30 square meters. A normal-scale dairy farm would need at least 30 sets of small high-speed fans while using large HVLS(High-Volume, Low-Speed) ceiling fans; one 7.3m/24ft HVLS fan is enough. Please take this as an example; one set, a 7.3m HVLS fan, is 1.5KW, and one set a 0.75m small high-speed fan is 0.36KW. All fans work for operating times. Under this situation, the electric consumption of a 7.3m/24ft HVLS fan is only degrees. At the same time, 0.75m small high-speed fans reach up to degrees. A large HVLS fan could help save degrees. Saving electricity is saving money for dairy farmers. What's more, using a lifetime of HVLS fans could reach up to 10 years, while low-high-speed fans only have two years. From this side, we can see obviously that HVLS fans could help save more money. Combined with the second advantage, we know large HVLS fans can reduce the number of sick cows. If dairy cows don't need to see the animal husbandry doctor, the farmer can save money again.

4.

Help dairy farm employees get a comfortable working environment and improve their work efficiency.

Large HVLS fans work for dairy cows and work for employees. HVLS fans can make employees feel cool by evaporating sweat. Workers would feel the comfortable wind like the natural wind with a soft and gentle wind. Under these good working conditions, workers would work more happily and increase their milking speed.

5.

Improve the air quality of dairy farms.

As we all know, farms are very smelly because of animal feces. Dairy farms are no exception. When a large HVLS fan is installed, the peculiar smell can be squeezed out by the fan's wind. Thereby improving the environment of the dairy farm. Workers can work happily in a less smelly environment.

6.

Keep dairy farms warm in winter.

In addition to cooling dairy cows, large HVLS fans can also be used in the winter months. HVLS fans can be set to reverse during those cold times and run at low speeds. Then the hot air above can be mixed with the cold air below, thereby increasing the overall ambient temperature. If combining large HVLS fans with some other warm equipment, the whole dairy farm can be heated up more quickly.

With rapid technology, apart from traditional geared HVLS fans, we have developed PMSM (permanent magnet synchronous motor) HVLS fans. In addition to the above advantages, PMSM HVLS fans could provide free maintenance, super silence, and small installing space. By using high-volume, low-speed, ultra-quiet fans, cows, workers, and farmers will become better. Cows will produce more milk, workers will have a better working environment, and farmers will get more profits.
