“ Dry ice pellets sublimates immediately
on striking the object. ”
This change from a solid to a gaseous form, the
accompanying tremendous expansion in volume,
the high kinetic energy and the low temperatures
are the most important factors which result in the
loosening of impurities.
Method
The dry ice blasting machine contains a dry ice pellet
tank and a dosing unit, which doses the dry ice pellets
into the jet of compressed air. By means of the com-
pressed air, the dry ice is transported through a special
blasting hose to the blasting gun and nozzle.
In the blasting gun, the air stream is accelerated, and
the dry ice pellets leave the nozzle of the blasting gun
at very high velocity.
Cleaning Effect
The cleaning effect of dry ice blasting is based on
three principles:
• Thermal Effect:
The dry ice pellets have a temperature of
-79°C/-110°F, and impurities are therefore
cooled down drastically; the impurities shrink
and loosen due to different thermal expansion
 coefcients.
• Kinetic Effect:
When the dry ice pellets leave the blasting gun
nozzle they have high kinetic energy and strike
the impurities at a speed almost equivalent to
the velocity of sound.
• Sublimation Effect / Volume Expansion:
The dry ice pellets are being pressed into the
brittle impurities and sublimate immediately on
contact. The resulting volume increase by a
factor of approx. 700 contributes to tearing
away deposited dirt.
In some cases the thermal effect will be the most
signicantfactor,inothercasesthekineticeffect
willbethemostsignicantfactor.
GENERAL INFORMATION
The dry ice blasting machine and its accessories
have been developed with the aim of supplying
cleaning equipment which minimizes consequential
cleaning costs and combines the best characteristics
of sand blasting and steam cleaning.
Dry AND Thermal Cleaning Process
Dry ice blasting provides a dry cleaning process
(familiar in sand blasting), AND a thermal cleaning
process (familiar in steam cleaning).
The blasting media itself (dry ice pellets) subli-
mates; this means that in most cases the process
can be used for cleaning components, machinery
and plant equipment without dismantling and often
without having to cover adjacent plant equipment.
No Residual Blasting Media
Dry ice blasting provides a dry and gentle, but
extremelyefcient,cleaningprocessthatleavesno
residual blasting media to be disposed of, and no
undesired substances that might penetrate into or
be deposited on machines and plant components.
This means that cleaning by dry ice blasting
becomes an excellent alternative to cleaning with
traditional methods.
DRY ICE BLASTING – How It Operates
Dry Ice Pellets
The dry ice blasting machine uses small CO2”par-
ticles” as the blasting medium, called dry ice pellets
(CO2– the chemical symbol for carbon dioxide).
In a machine commonly known as a pelletizer, liquid
CO2is used to produce hard and uniform dry ice pellets.
The pellets are approx. 3 mm (0.1 inch) in diameter
and approx. 10 mm (0.4 inch) in length – or rice-sized.
These dry ice pellets have a temperature of -79°C/
-110°F. When used for dry ice blasting, the pellets
are blasted onto the object to be cleaned at a very
high velocity. On contact with the surface of the
object, they immediately change from a solid to a
gaseous form as they heat up on impact.

SAFETY REGULATIONS
General
This manual contains instructions and safety regula-
tions which must be followed while starting, opera-
ting and maintaining the dry ice blasting machine.
It is important that the manual is kept, so the
operator always knows its exact location. It is also
important the owner makes certain that the
operator reads, understands and follows the con-
tents of the manual.
Personnel Qualications
Personnel responsible for operation, servicing and
maintenancemustbesuitablyqualiedtoperform
these functions.
Special training in machine handling as well as
repair and maintenance is offered by the manufac-
turer of the machine.
The owner of the machine must ensure that the
person appointed to operate the dry ice blasting
machine fully understands and is able to follow the
SAFETY REGULATIONS denedinthefollowing
pages, and the WARNING SYMBOLS located on
the machine.
Safety and Risk
The machine is constructed to comply with the
standards and clauses contained in the declaration
of conformity and the terms of sale. Therefore, pro-
vided the manufacturer’s instructions are followed,
the machine will not pose any risk to the operator.
Precautions during Blasting
Air, CO2gas and dry ice pellets leave the gun nozzle
at a very high velocity (up to 300 m/s – 984 ft/s).
Therefore,
• donotaimthenozzleataperson(s)orinthe
direction of a place(s) where other people work,
• remember,dryicepelletscanbedeectedback
from the object being cleaned,
• donotaimthenozzleindirectionswhere
damage might result.
Do not use the machine “for fun” and under no
circumstances should you aim the gun nozzle at
persons or other living creatures.

MANUAL for KG30 - KG50 SUpreMe
DRY ICE BLASTING EQUIPMENT FROM ICETECH | PAGE 4
Danger of Thrown Loose Objects
There is a risk of dry ice pellets and small objects
beingdeectedbackduringblasting.
Thereforesmallobjectsmustbermlysecuredbe-
fore blasting. Loose objects must not be left in the
area where the cleaning process is taking place!!
The operator must always wear approved protective
goggles or a protective shield when working with
the dry ice blasting machine. This also applies to
anybody near the workspace.
Noise
Because of the high air velocities in the gun nozzle
during dry ice blasting, the level of noise in the area
where the operator works may exceed the maximum
permissible level. The owner is responsible for keeping
himself acquainted with, and informing the operator of
any precautions to be taken as to the application of ear
protection, since legislation on maximum permissible
noise levels varies from one country to another.
Static Electricity
Serious discharge of static electricity can occur.
Always make sure that objects to be cleaned are
adequately earthed/grounded and that this ear-
thing/grounding remains stable throughout the
whole cleaning process.
The dry ice blasting machine is earthed/grounded,
from machine cabinet to blasting gun, and through
the main electricity connection on the rear side of
the machine – provided that the machine has been
set up and connected as described under STARTING
THE DRY ICE BLASTING MACHINE page 10.
PACEMAKER Precautions
Do NOT use the dry ice blasting machine, if you are
wearing a pacemaker. The dry ice blasting machine
may cause pacemaker malfunction.
Explosive Hazard
The machine must never be used in surroun-
dings where there is a danger of explosion.
Despite optimum earthing/grounding of both ma-
chine and cleaning object, static electricity can be
generated and create a spark.
Danger of Congelation
At atmospheric pressure, CO2in a solid form has
a temperature of -79°C/-110°F or lower and can
give rise to congelation when the dry ice comes in
contact with unprotected skin.
Important!
Therefore, always read the safety data sheet pro-
vided by the dry ice supplier, and follow the instruc-
tions given.
“ Dry ice pellets are non-toxic, non-abrasive
and free of moisture. Therefore, dry ice
blasting is applicable for a large number of
industries. ”

MANUAL for KG30 - KG50 SUpreMe
DRY ICE BLASTING EQUIPMENT FROM ICETECH | PAGE 5
Dust
Certain types of dust have a tendency to pulverize
during the cleaning process. Therefore we recom-
mend that the operator wears a dust mask or if
necessary a breathing mask and industrial protec-
tive clothing.
The owner is responsible for keeping himself
acquainted with, and informing the operator of any
precautions to be taken as to the application of dust
masks, since the limit value varies from one country
to another.
Danger of Congelation
When using the dry ice blasting machine, the opera-
tor must wear long-sleeved industrial protective
clothing in order to eliminate the risk of congelation
when the dry ice comes in contact with unprotected
skin.
Read the safety data sheet provided by the
dry ice supplier and follow the instructions
given.
CO2Detector
The presence of a CO2detector is recommended in
areas of limited ventilation such as rooms, closed
tanks, etc. The CO2detector can be installed to in-
terrupt the blasting process before the CO2concen-
tration exceeds a prescribed limit.
CO2Concentrations
Dry ice pellets are CO2in a solid form. At normal
atmospheric pressure, CO2can only exist in a solid
form at a temperature of -79°C/-110°F or lower.
When CO2is used as a blasting medium, it becomes
heated and changes into a gaseous form. As CO2
hasahigherspecicgravitythanordinaryatmos-
pheric air, inhaled air will contain CO2– especially
if the blasting process takes place in small or partly
closed rooms.
In such conditions there is a risk of the oxygen con-
tent of inhaled air being replaced by CO2. Therefore
it is essential to make sure the room is well venti-
lated when dry ice blasting!!
Note that
• lowCO2concentrations (3-5%) result in
headaches and rapid breathing,
• CO2concentrations of 7-10% produce head-
aches and nausea, and may lead to uncon-
sciousness,
• higherCO2concentrations lead to unconscious-
ness and in the worst case – suffocation.
As stated above, high CO2concentrations can
displace oxygen and result in unconsciousness.
Therefore, avoid using the dry ice blasting machine
in spaces/rooms where ventilation is limited.
“ When using the blasting equipment,
the operator must wear gloves in order to
eliminate the risk of being burned. ”

When the cleaning task has been completed, the
following procedure must be carried out before the
machine is dismantled or stored:
• Emptythehopper.
• Activatethetriggerontheblastinggun
for a few seconds in order to empty the system
of possible dry ice residue.
• Closethecompressedairsupply.
• Activatethetriggerontheblastinggunforafew
seconds in order to depressurize the system.
• Turnoffthemachine(presstheredOFFbutton).
• Disconnectthemainpowersupply.
• Disconnectthecompressedairsupply.
• Itisrecommendedtodisconnectthe
blasting hose.
CORRECT ORDER IS IMPORTANT!
FIRST disconnect the signal cable – THEN the
blasting hose couplings!!
• Avoidkinkingtheblastinghose,whenrolling
it up.
EMERGENCY STOP
Activation of the emergency stop button immediately
stopstheblastingairstreamandthedryiceow.

PRECAUTIONS – BLASTING HOSE
Connection and Disconnection
Never disconnect the blasting hose from the ma-
chine or blasting gun when the main power supply
and/or compressed air supply are connected. Other-
wise activation of the trigger on the blasting gun will
result in a discharge of blasting air through an open
outlet instead of through the blasting gun nozzle.
If this happens, the operator will lose control of the
air stream, and serious injury may result.
CORRECT ORDER IS IMPORTANT!!
• Connection:
FIRST connect the blasting hose couplings
– THEN the signal cable!!
• Disconnection:
FIRST disconnect the signal cable
– THEN the blasting hose couplings!!
Defective Blasting Hose
The outer hose sleeve protects the operator from
any exposure caused by wear and tear of the inner
hose. No pressure build-up is permissible in the outer
sleeve during operation.
If a defective blasting hose is used, the operator
risks serious injury from being hit by dry ice pel-
lets.
Anysignofinationmeansthattheinnerhoseisin
some way defective.
NOTE:
If that fault occurs, stop the machine
IMMEDIATELY:
• Closethecompressedairsupplyimmediately.
• Activatethetriggerontheblastinggun

Nozzle Diameter and Blast Pattern
Thenozzleselectionshouldbebasedonnding
the best combination of air consumption, dry ice
consumptionandcleaningefciency.
The selection of the nozzle spread angle should
depend on how strong or weak a cleaning effect is
desired for a given dry ice consumption.
Small Blast Pattern
A small blast pattern gives a concentrated jet with a
high cleaning effect on a small area.
Wide Blast Pattern
Alargespreadangle,e.g.theatnozzle,resultsin
a jet which for the same consumption of dry ice and
air cleans a larger area with a lesser cleaning effect.
Nozzle Size
It is most important to select the size of nozzle
which will provide the desired air velocity using
the available compressor capacity. Choosing the
right nozzle size and type will optimize not only the
cleaning effect, but also the dry ice consumption
and the time required for the cleaning process itself.
Refer to the air consumption table for guidance on
the nozzle selection.
Air Consumption Table
The air consumption table indicates the air con-
sumption in relation to nozzle size and blasting
pressure. The maximum supply pressure of KG50
and KG30 amounts to 16 bar/232 psi.
Example of Use of the Table
The air consumption table outlines the air consump-
tion achieved with the nozzle sizes available. If for
example a size 8 nozzle is used at a blasting pres-
sure of 6 bar (87 psi) the air consumption amounts
to 4.2 Nm3/min (148.3 ft3/min).
The available compressor capacity will always need
to be taken into consideration and therefore it may
be necessary to do some test blasts and observe
the results until the optimum combination of nozzle
size and blasting pressure for a certain application
is found.
