Below is a list of Liquid Chillers manufacturers from Harvard, Illinois. Liquid chillers are refrigeration systems that chill liquids such as water, oil, brine, alcohol, coolants, chemicals and beverage or food ingredients for industrial applications. Their design and construction are very similar to air conditioners, and they range vastly in size. They may be fabricated as small, localized units for small applications or as large central chiller systems combining many heat exchangers and external cooling towers that span an entire facility.
