A 30 ton water chiller is a large industrial cooling system that is used to cool water or other fluids. It is typically used in large commercial and industrial buildings, such as factories, warehouses, and office buildings. The chiller works by circulating chilled water through a closed loop system, which is then used to cool the air in the building. The water is cooled by an evaporator, which is a device that uses a refrigerant to absorb heat from the water. The evaporator then transfers the heat to a condenser, which releases the heat into the atmosphere. The cooled water is then circulated back to the evaporator to start the process again. The 30 ton water chiller is capable of cooling large amounts of water quickly and efficiently, making it an ideal choice for large-scale cooling needs.
