Abstract: A snow making tower is illustrated wherein an elongated tower conduit combination is provided which includes an elongated air conduit extending within the water conduit and air and first water discharge nozzles are respectively provided adjacent the upper ends of the air and water conduits and positioned for producing a plume of atomized water from external interacting air and water discharged under pressure from the air and first water discharge nozzles to produce snow in subfreezing ambient conditions. These first water discharge nozzles have a nozzle discharge passage in their sides which are positioned to direct a jet of water into air immediately discharged under pressure from the air discharge nozzles prior to the external main interacting of air and water which produces the plume. This provides preliminary atomization of water in the air discharged prior to its interaction for producing a more finely atomized plume.

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.
