Breweries are known for transforming malt, hops, and yeast into beer in gleaming brewing kettles and large fermentation tanks linked by numerous pipes.
Over the centuries, the equipment for mashing, lautering, boiling, and fermenting beer according to carefully guarded recipes has been steadily perfected.
The chiller is the heart of the brewery
One of the most important parts of the brewery, and perhaps the least visible, is the chiller. The fermentation temperature of the beer is crucial, which means that the heat generated by the yeast fermentation must be carefully controlled by the chiller.
If the beer ferments at too high a temperature, the yeast can produce a variety of undesirable aromas that ruin the beer.
According to Justin Thomas, President of G&D Chillers, based in Oregon
"The chiller is the heart of the brewery. Owners invest not only a lot of money in the brewery and brewing equipment, but also a great deal of time in the production of beer. But if the chiller fails, all that goes out the window."
Partnerships to keep pace with growth
Thomas says that growth at G&D Chillers has been exponential over the past 15 years. To continue this rate of success, the company had to look for new ways to meet customer demands for reliable, state-of-the-art chiller options.
For example, G&D Chillers recently teamed up with Siemens and the global distribution and supply chain solutions company WESCO to meet these needs and stay ahead of the competition. "We're still a small manufacturing company, but big enough to produce some technically advanced equipment," says Thomas. "We've always been service-oriented and always stood by our equipment, no matter what the problem. We get the same kind of support and service from Siemens that we give to our own customers."
