Snowmaker 2
Old and new Snowmaker
Snowmaker 3
From prototype I to prototype II
Old and new Snowmaker
• Both prototypes use the same main principles to produce nature-identical snow• the ice crystals are brushed off the nylon cords instead of vibration motor• Some components were transferred from old to new Snowmaker
Higher reproducibility of the snow cristal size Higher amount of snow production High flexiblity because of modules on wheels (e.g. defrosting) Compacter device
Advantages
There is no CE certification for this machine
Snowmaker 4
Design (CAD, NX UGS)
• Single parts: construction number_PRT.prt• Assemblies: construction number_ASM.prt• Drawings: construction number_DWG.prt• For ordering: construction number_XXX.pdf
It is possible to export the files into other formats (iges, step, dxf)

Design (Assemblies)
1: Water evaporation basin («Wasserbecken»)
Water basin mady of aluminum with heating coil Fan and motor Electronics
2: Nucleation chamber («Nukleationskammer»)
Nylon wires Brush rack on linear guides Snow accumulation box Door
3: Condensation of residual humidity («Schneefänger»)

Snowmaker 6
Design main frame by item Schweiz
All parts which belong to the main frame of the Snowmaker are composed with the aluminum profile system from item Schweiz.
We made the construction (we defined the all dimensions) in CAD … BUT NOT how the single elements are connected. This was done by item company
