Why are HVLS fans suitable for dairy farms?

Large HVLS (high-volume, low-speed) fans, while often found in industrial settings, are particularly advantageous for dairy farms. These fans provide a solution for ventilation and cooling on dairy farms, leading to increased milk production and a reduction in diseases among dairy cows. Initially, HVLS fans were developed specifically for animal husbandry. In the last century, U.S. farmers sought a better method to cool their cows and reduce heat stress; it is widely recognized in the dairy farming community that when cows are comfortable, they eat more and subsequently produce more milk. The first incarnation of the HVLS fan emerged from the concept of using an electric motor to drive large fan blades, leading to their eventual widespread adoption in industrial environments.

Advantages of Installing HVLS Fans on Dairy Farms

1.

Enhances cow comfort and milk production.

For further information, please visit our website. The HVLS fan features a 24ft (7.3m) diameter, allowing it to deliver significant air volume. Rotating at a slow speed of just 54 RPM, the fan creates a gentle, quiet airflow that keeps cows comfortable. When cows feel relaxed and happy, they consume more feed and produce higher quality milk.

2.

Increases the lifespan of cows.

In humid conditions, cows are more susceptible to illness, which can shorten their lifespan. The installation of HVLS fans reduces moisture in the air by evaporating excess water vapor, creating a drier environment. This reduction in humidity decreases bacterial growth, leading to fewer illnesses among cows and promoting longer lifespans.

3.

Reduces electricity expenses for farmers.

One 7.3m (24ft) diameter HVLS fan can cover significant square footage while using only 1 KWH of electricity per hour. Many dairy farmers initially rely on high-speed fans, which create uncomfortable gusts of wind. In contrast, one HVLS fan can replace the need for multiple smaller fans (which typically only cover 15 to 30 square meters each). For instance, a 7.3m HVLS fan operating at 1.5 KW efficiently outperforms the energy consumption of several smaller fans combined, resulting in substantial energy savings over time. Additionally, HVLS fans can last up to 10 years, significantly outpacing the two-year lifespan of traditional high-speed fans. When cows become healthier due to reduced illness, further savings on veterinary costs are realized.

4.

Creates a comfortable working environment for farm employees.

HVLS fans not only benefit cows, but they also improve comfort for farm workers. The gentle breeze produced by these fans helps evaporate sweat, creating a pleasant working condition. When employees are comfortable, their productivity increases, particularly during milking operations.

5.

Enhances the overall air quality on dairy farms.

Dairy farms often contend with unpleasant odors due to animal waste. The airflow generated by HVLS fans can help disperse these odors, resulting in a more pleasant environment for both cows and farm workers.

6.

Provides warmth during the winter months.

HVLS fans can also be beneficial in winter by running in reverse, which redistributes warm air collected near the ceiling to the colder air at ground level. This mixing effect can quickly increase overall temperatures, particularly when paired with additional heating equipment.

As technology progresses, we now have PMSM (permanent magnet synchronous motor) HVLS fans. In addition to the benefits already discussed, these advanced fans require no maintenance, operate silently, and take up minimal installation space. High-volume, low-speed, ultra-quiet fans create an optimal environment for cows, employees, and farmers alike. As a result, cows produce more milk, workers enjoy better conditions, and farmers realize increased profits.
