For automated applications under extreme climatic conditions and 24/7 use, CryoSnow has developed an additional nozzle isolation for different nozzles. This additional insulation of the nozzle prevents any condensation on the nozzle surface. In particular, for applications at high humidity (> 65%) and higher room temperature (< 25 °C) of the ambient or cabin air with this solution, a possible formation of condensation is completely avoided. The insulation shells are easy to assemble and of course can also be retrofitted.
