My responsibility is manager for Wolf Pack farms. Wolf Pack is actually 2 sow farms totaling 7800 sows. We also do the finishing for these farms on site.
We have Edstrom cooling in gestation, farrowing, and finishing. The precision of the Edstrom C-440S controller with the use of check valves has helped us greatly reduce both number and severity of shoulder sores. Before we installed the Edstrom cooling, we ran water on the sows using time clocks. Because of having to let the water run for too long and then the lines draining we were unable to keep the sows from getting too wet.
We are able to cool the sows efficiently using as little water as possible thanks to the sequencing feature of the C-440s and the utilization of Smart Mode, We like the fact that we can shorten the cooling cycle without manually resetting the controller. This makes management of the cooling process much easier.
The Edstrom Controllers are the most cost effective way to cool animals that I have seen."
