DRY ICE CLEANING<br />
DRY ICE CLEANING<br />
Ice cold in the face of dirt – gentle on surfaces.<br />
Lots of parts and machines are difficult to clean – casting moulds, extruders, processing machines in the food and plastics industries.<br />
Whenever water and steam cannot be used as cleaning agents, for example due to a risk of corrosion. Or if residues from blasting<br />
material such as sand or glass must be avoided. For hygiene reasons or because of sensitive surfaces. Or to avoid time-consuming<br />
clear-ups, reassembly and polishing after cleaning. Kärcher closes this gap with the powerful Ice Blasters.<br />

1 Advantages of dry ice blasting<br />
Cleaning without disassembling<br />
Machines do not have to be disassembled for cleaning. The pellets<br />
easily reach into even the smallest nooks and crannies.<br />
Short machine downtimes<br />
thanks to fast and effective cleaning.<br />
Environmentally friendly cleaning<br />
without additional chemicals or spray agents.<br />
Surfaces are not damaged<br />
No residues<br />
Dry ice sublimates to CO₂ without residue. It leaves no residue, such<br />
as spray agents or waste water.<br />
2 Cleanliness = cold times acceleration<br />
The Ice Blaster accelerates the dry ice pellets, which are up to 3 mm in size,<br />
with compressed air to over 150 m/s. With the coldness of –79°C, the dirt<br />
freezes and cracks. The dry ice pellets ejected at a high speed can then<br />
remove the dirt easily. A highly effective method for removing almost any<br />
dirt in a way that is gentle on materials.<br />
3 From carbon dioxide to ice<br />
In the production process, liquid carbon dioxide flows into the press cylinder<br />
of the pelletiser and as a result of the pressure drop turns to dry ice snow.<br />
A hydraulic cylinder condenses this dry ice snow, which is then pressed by<br />
an extruder plate. This creates small rods of dry ice which then break into<br />
pellets.<br />
4 Safety, convenience and practicality are built-in<br />
Kärcher’s Ice Blasters provide the right solution for every application. The<br />
machines’ robust structure and reliable technology cannot fail to impress. A<br />
host of features, such as residual ice discharge, a cleverly designed protective<br />
handle, lockable blasting parameters, integrated water separator and many<br />
more, make everyday work significantly easier.<br />
