The method in brief |
| |
|
Blasting methods such as sand
blasting for remove paint, dirt, grease and similar coatings
from surfaces are well known. The industry is using dry ice pellets
for many years as an effective blasting agent. The main advantage
of this cleaning method is that the dry ice pellets sublime
completely after blasting. Only the removed soiling remains.
This makes dry ice blasting a particularly effective,
environmentally friendly cleaning method, which is not
abrasive to the materials to be cleaned.

What is Dry
Ice? |
| |
|
The blasting agent which
consists of dry ice is the solid form of CO2
(carbon dioxide) at a temperature of -79°C.
The carbon dioxide is an odourless, non-toxic gas
which
is used in the
drinks industry as an additive in beer and
mineral water,
for instance. The addition of carbon dioxide
means the fresh
taste and the shelf life of the drinks can
be guaranteed
for longer. It is also used in the food industry
for cooling meat and sau-sages. |

How is Dry Ice Produced? |
| |
|
Liquid carbon dioxide is directed from a low-pressure
storage
CO2
Tank into a special machine the
Pelletizer
, and depres-surised using a dispenser valve.
This procedure forms dry ice snow at a temperature of
-79°C. The interactive piston in the pelletizer presses the
dry ice snow through a die to form, dense
Dry Ice Pellets

Where
do you get Dry Ice Pellets from? |
| |
|
The easiest way is to
produce dry ice pellets yourself with
the DIS Dry Ice Systems pelletizer. If
your requirement is
low, dry ice is available from gas
suppliers nationwide and
can be stored for around seven days in
special insulated
boxes.
Simply request our list of suppliers. |
