  • Patent number: 4597524
    Abstract: The disclosure relates to an improved snow making machine for ski areas and the like, which enables the snow making process to be carried out with greater efficiency than heretofore and with simplifications in the basic equipment requirements. The apparatus utilizes water and compressed air supplies, conventionally provided at the site and extracts a fraction of the energy available in the pressurized water supply by first passing the water through a turbine motor driving an axial fan. The water exiting from the turbine is then mixed with compressed air in a plurality of nozzles and discharged into the air stream created by the turbine-driven axial fan. The equipment makes possible the production of large volumes of high quality snow with greatly reduced requirements for compressed air utilization.

  • Patent number: 4593854
    Abstract: A snow-making machine is disclosed which includes a first group of air-water snow-making nozzles and a second group of airless, water atomizing nozzles. A distributional air fan is driven by a water turbine. Water for the air-water snow-making nozzles is derived from the outlet side of the turbine, while water for the airless nozzles is derived from the intake side of the turbine. A novel construction of air-water manifold ring and air-water nozzles associated therewith is also described. The construction provides a high efficiency, low cost, lightweight snow-making unit, ideally suited for ski area snow-making operations.
