A 5 ton water cooled chiller is a type of cooling system that uses water to transfer heat away from a designated area. It is typically used in commercial and industrial applications to cool large spaces such as factories, warehouses, and office buildings. The 5 ton rating refers to the amount of heat that the chiller can remove from the air in a given period of time. This rating is based on the British Thermal Unit (BTU) and is equivalent to 12,000 BTUs per hour. A 5 ton water cooled chiller works by circulating water through a heat exchanger, which is then cooled by a refrigerant. The cooled water is then circulated back through the heat exchanger to cool the air. This type of chiller is often used in combination with other cooling systems such as air conditioners or evaporative coolers to provide the most efficient cooling solution.
