Glycol Process Chillers for Brewery, Distillery and Fermentation Applications

Glycol Chillers: What are they, really? We regularly get calls asking, “What’s the difference between a glycol chiller and a regular chiller?” Well, the answer to this question is easy and complicated at the same time.

Setting a glycol chiller next to a standard chiller (made by the same manufacturer), most people would say they look like the same chiller and this would be correct. They both remove heat from fluid however a glycol chiller is specially designed to reduce the process fluid to below freezing in most cases. To do this, the process cooling medium (generally water) must be mixed with either Propylene or Ethylene glycol. Depending on glycol concentration, the process fluid with glycol and be reduced from 32°F down to -30°F.

To make your selection of the correct glycol process chiller easier, Legacy has developed OEM designs for many of the most common process chillers used for Brewery’s, Distillery’s and other Fermentation production. If you don’t see Glycol chiller for your specific requirement below, not to worry, we have dedicated process chiller application engineers available to assist you. Just give us a call at 877-988-5464.

Why Choose a Legacy Process Chiller for your Brewery, Distillery or Fermentation Application?

Glycol Process Chiller Statement of Value: Each of our fluid cooling systems are specifically designed to meet the 24/7/365 demands of any fermentation process. During production each, built to order, chiller undergoes rigorous quality control with extensive QC during and after final load testing.

Comment about tables below: Process chiller assignments nested into the tables below are based on available information at the time we generated them. As with many industries, technical characteristics are very dynamic, tending to change often. As such ALWAYS check with your Legacy Process Engineer prior to specifying or purchasing your process chiller. The operating conditions used to assign process chillers in the tables below are 95F ambient (Air-Cooled) and 105F condensing (or 75F entering water temp for Water-Cooled) and 45F leaving WATER ONLY temp going to the process. If your conditions vary from these industry standards, please contact Legacy Chillers (877-988-5464) for an updated selection.
