This kind of cleaning uses dry ice pellets for the
cleaning of surfaces.
As soon as the CO2 pellets meets the surface,
it will be cooled and the sticking pollution is
eliminated by the hypothermia. The resulting
differing extension creates mechanical tensions
between the surface material and the pollution –
the dirt particles come off. The kinetic energy
created by the impact breaks up the coat of dirt,
the solid CO2 turns into gas and penetrates
between the coat of dirt and the surface. As
during this transforming a volume extension occurs, the dirt is being eliminated completely of
the surface and is taken away by the stream of compressed air.

Environment-friendly
no strain of the ground water
only the real pollution has to be recycled
no action of ecologically harmful chemistry
the surface is not being damaged
Reduction of costs
minimum of standstill time of the machines
no aftercare in form of drying
no costs for the recycling of material like sand, polluted water etc.
Flexible use
independent of energy supply
possibility to clean all parts in installed condition / locally
In order to clean a Heidelberg SM 102 printing tower with ordinary finery means you need
approximately 40 hours. With dry ice you can do it in 8 hours.
This method we offer as well locally at your premises. We dispose of a special Service car with
compressors, cold dryer and all necessary finery means. In order to avoid more standstill times
than necessary our technicians come as well on weekends.
