The control unit incorporates all safety, monitoring and operating components. It includes the connections for the liquid CO2 and compressed air. The liquid CO2 supply of the manual CO2 snow blasting machines is mostly supplied using CO2 cylinders (content from 10 up to 37.5 kg) or CO2 bundles (content 450 kg), each with a dip tube. The compressed air supply is provided either via the house network or via a screw-type compressor. A power supply is not necessary. The compressed air supply hose is attached using a safety coupling on the control unit as well as on the supply connection. The length of the hose is variable as individual hoses can be connected to each other without any loss of power. The connected hoses can reach several hundred metres. The liquid CO2 supply hose is equally flexible in length and can be extended as required. Due to the high supply pressure of the CO2 cylinders or bundles (50 to 60 bar), the machines can be implemented when there is a long distance to cover to the control unit and/or a great height difference, without any loss of power.
The hose package connects the control unit with the blasting pistol. It is comprised of a high-pressure CO2 pipe, a special compressed air hose, pneumatic control lines, an earthing cable, a flexible casing and connectors for both the control unit and the blasting pistol. The hose package can be completed in almost any length without any loss in power and can be subsequently lengthened.
The blasting pistol is the technological centre of the CO2 snow blasting process. This is where the production of CO2 snow particles takes place and the apportioning of these particles into the compressed air flow. The apportioning of the CO2 is also possible with the blasting pistol. In addition, there is an ergonomic hand grip with a safety lever on the blasting pistol. The blasting pistol is thermally insulated, so that contact with cold surfaces and condensation is avoided.
Nozzles are available either round or flat or customized as required. The fluidic flow of all nozzles is optimized. In addition, all nozzles are made of an impact resistant, thermally insulated special synthetic material. Wear and tear of nozzles does not occur. The flat nozzles allow a blasting width of more than 100 mm.
