Dairy cows experience heat stress when the temperature-humidity index is above 72°. In humid and hot temperature, they have trouble getting rid of the heat generated by digestion and metabolic processes. Your milk production and reproduction rate will decrease if your cows are experiencing heat stress. Furthermore, Heat-stressed cows will decrease their water & dry matter consumption. Remember that heat stress affects dairy cows at a temperature and humidity level that may not affect humans.

What is PANEL FAN?
The Panel Fan was one of the first ventilators to be created explicitly for livestock only. While improving them over the years, our Panel Fans have proven that we can rely on their efficiency. They provide a more uniform micro-climate in many livestock applications. Combining great air movement over a wide area with a very low noise production and energy consumption. They are a perfect choice for most dairy farms. Especially above single rows of beds, smaller and lower barns and close to robots.

What Do Real Farmers Say?
"Best investment in years"
​"As summer temperatures in the Netherlands are becoming higher and longer every year, I had been looking to buy some fans earlier that year. Through my local electrical engineering company, I heard that Topcool Panel fans delivered a good job on removing heat stress effects from dairy cows. I visited two other farmers who have already installed the Topcool fans for about a year. After visiting their facilities and getting their feedback, I invested in these fans myself. I must say I should have done this 10 year ago already. What a difference in cooling and getting the cows to the feed rail. Best investment in years."
