While it may be hot outside, it’s not too early for reviewing winter heating and ventilation details. This past week I was at a sow unit where the original 500 sow facilities were constructed in 1991 and the site has grown to 2500 females over the years. As we went through the site reviewing controller and inlet settings for both summer and winter, we got into a discussion of propane usage.
I asked if the site had ever done a high pressure test of their propane supply lines from the bulk tank. The answer was not as far as anyone knew. The need for this test was then highlighted by severe corrosion noted on one of the copper supply lines entering one of the animal areas from the outside.
