A cooling system that can’t keep up with beer demand is bad news for any brewery—as the Heileman division of Stroh Brewery Company found out. But an in-depth study of their cooling pump system, and an impeller trim, got their system back up to par while saving them $19,000 a year in energy costs. On top of that they now have a pumping system that’s twice as efficient. COOLING BEER IS HOT TOPIC “We couldn’t have as many fermenters on as we would like to have,” reports Dan Schaller, former plant engineer at the La Crosse facility. The system that…

Ellsworth Cooperative Creamery used a performance optimization study performed by Michaels Engineering to take a close look at production processes. In doing this, they found a source of inefficiency that was wasting over $1000 a month! Throughout the course of the study, Michaels was able to identify particular systems that should be changed to operate more efficiently. The study revealed that the exhaust fan’s damper was partially closed to regulate airflow, and that slowing down the fan while opening the damper would achieve the same airflow using half the energy. Ellsworth followed the study’s recommendations, which ultimately saved them $12,000…
