An evaporative cooling medium and low-temperature screw chiller in a brewery cooling system is an industrial-grade refrigeration unit designed to efficiently maintain low temperatures during brewing processes—particularly for wort cooling, fermentation temperature control, and cold storage. Here’s a breakdown of its components and purpose:
What is a Screw Chiller?
A screw chiller uses a rotary screw compressor to compress refrigerant.
Known for high efficiency, quiet operation, and reliable continuous duty.
Ideal for medium to large breweries needing 24/7 cooling.
Evaporative Cooling Explained:
Evaporative condensers use water evaporation and airflow to cool the refrigerant.
Compared to air-cooled or water-cooled systems, evaporative cooling is: More energy-efficient. Offers better heat rejection, especially in hot climates. Reduces overall cooling water consumption.
Medium and Low-Temperature Range:
Medium-temperature chillers: Typically maintain temperatures around +5°C to +15°C—used for fermentation tanks.
Low-temperature chillers: Go down to -5°C to -10°C or lower—used for:
*Cold crashing.
*Glycol cooling loops.
*Cold storage of finished beer.

How it Fits in a Brewery:
Connects to glycol cooling lines that run through:
Fermenters (unitanks).
Bright beer tanks (BBTs).
Wort heat exchangers.
Provides precise control over fermentation and storage temperatures.
Advantages in a Brewery Setup:
High cooling capacity—suitable for large-volume or continuous production.
Energy-efficient due to evaporative design.
Reliable and low-maintenance compared to reciprocating compressors.
