In a brewery, significant amounts of electricity are consumed by the cooling systems. To ensure sustainable and cost-effective beer production, it is crucial that the refrigeration systems operate efficiently and are appropriately sized. Sizing a brewery water chiller depends on various factors, including the brewery’s specific requirements and the desired cooling capacity. Initially, it is essential to determine the exact cooling demand of the brewery. This is influenced by several factors, such as the brewery’s size, production capacity, the number of brewing processes per day, and the required cooling temperature. Depending on the brewery’s size, the cooling demand can range from a few kilowatts to several hundred kilowatts.
