cowkool system installed- July 2004

"We wanted to see exactly what the CowKool system would do for our dairy, so we installed the CowKool system only in Anchor J dairy to compare to what we've always done during the summer."

'Anchor J dairy and Flying H dairy (also known as Stevinson Corporation ca.) are two side-by-side dairies operated under the same management… same feed… same housing… same water… same milking parlor… same people.'

"We saw a huge difference! All in all we saw over $100,000 in summer-time income benefits as a result of the CowKool system. The numbers speak for themselves."

CowKool system installed- July 2003

"I've never seen a fan that works like this. It still works today as if it were brand new, and it's been 5 years.

The thing that matters to me the most is that the cows seem happy and relaxed even in the summer.

We have two types of cooling methods- one is the CowKool system and the other is a system of simple misters.  On really hot days when the temperature is over 100°F, you can see the cows in the pens with the misters really exhausted and panting heavily. The cows that are in the pen with the CowKool system act as if it was a nice spring day.

Its like the CowKool system basically takes the summer out of dairying.


I would highly recommend the CowKool system to any dairy that gets hot summers."

“We installed our CowKool system in the hospital pen and the fresh cow pen. The results were very positive. For the hospital cows we found that we used half the supportive medicine compared to what we were using before. We also found that our death loss went down.  In the fresh cows had far less metritis, and the cases we did have responded to treatment better than before.

All in all I'd say that we cut our drug use in half and had better success treating the cows than before we installed the system.

Regarding the fans, we find the quality very, very good.

We're very satisfied with our CowKool system
and I would definitely recommend it to any dairyman”

"We installed the CowKool system in our fresh cow pens to give them the best condition we could.
As we get pretty hot summers here in California we did not see the negative summertime effects on our fresh cows as we previously did.
The feed intake was very good and our fresh cows do very well now."


"We have noticed that our high cow groups are producing much more milk during the summer than before. 
As we have made other management changes in addition to installing the CowKool system it’s difficult to isolate the system’s effect alone, but I'm sure the cooling system had a substantial contribution to the increase of milk during the summer months."

"We tried other fans in the past but had a lot of problems. We’ve had our CowKool fans in now for 25 years and what a difference! No other fan that I’m aware of comes close to the quality of the CowKool fan."

"I’ve had my CowKool fans in now for 20 years. I’m now rebuilding all of the barns and will stay with the CowKool System. My summer time milk production is the same as my winter time production. I’d recommend this system to any dairyman."
