Title: Snow making tower with antifreeze precooling system

Abstract: A snow making tower with a water and air precooling system. An elongated aluminum pipe snow making tower is supported above ground in an upright manner and is provided with snow making nozzles at its upper end for ejecting air and water under pressure into ambient atmosphere for manufacturing snow in subfreezing conditions. Water and air supply connections are provided at the lower end for connection to sources of water and air under pressure. A closed loop antifreeze cooling system is mounted adjacent this tower and includes a radiator, a circulating pump and tubing for continually recirculating antifreeze fluid through the radiator with the pump. This tubing includes metal tubing that passes within the interiors of the aluminum pipe snow making tower for thereby precooking water and air passing through the tower prior to ejection from the snow making nozzles.
