“ Dry Ice pellets are non-toxic,
non-abrasive and free of moisture.
Therefore, dry ice
blasting is applicable for a large
number of industries. ”
GENERAL INFORMATION
The dry ice blasting machine and its accessories
have been developed with the aim of supplying
cleaning equipment which will minimise conse-
quential cleaning costs, and which also combines
the best characteristics of sand blasting and steam
cleaning.
The dry ice process provides the dry cleaning
process familiar in steam cleaning where thermal
effects loosen impurities. The dry ice blasting
machine now developed offers equipment which
with a totally dry cleaning process not only removes
impurities from the surfaces being cleaned; it also
leaves no waste products. The blasting/cleaning
medium itself evaporates. This means that in most
cases the process can be used for cleaning machin-
ery – without dismantling, and as a rule without
having to cover adjacent plant.
Cleaning in Industry
In industrial processes it is often impossible to avoid
production apparatus from getting dirty, with the
consequent impairment of production reliability,
product quality, and the safety of personnel.
Thus, regular and preventive cleaning of production
apparatus becomes part of many company plans to
achieve problem-free production.
Production and maintenance crews all over the
world therefore constantly seek cleaning methods
which increase product quality, which are
cost-saving, and which at the same time are
environmentally sound. In today’s high-tech and
often highly automated plant, traditional cleaning
methods are not always the optimum.
They place extra load on machines, personnel and
the environment, or involve extensive dismantling to
ensure that cleaning will not cause damage. Dry ice
blasting provides a gentle, dry and efcient cleaning
process that leaves no waste products behind it, i.e.
undesired substances that might penetrate into or
be deposited on machine components.
This means that cleaning by dry ice blasting
becomes an excellent alternative to cleaning with
traditional equipment.

“ Drastic reduction of waste problems.
No abrasive effect. ”
DRY ICE BLASTING – HOW IT OPERATES
Method
Dry ice blasting equipment uses small CO2”par-
ticles” as the blasting medium – in the following
called Dry Ice pellets. (CO2– the chemical denomi-
nation for carbon dioxide). Liquid CO2is expanded
in a special unit to CO2snow. This substance is then
subjected to high pressure and is forced through a
matrix to create hard and uniform pellets of approx.
3 mm in diameter and 10 mm long.
These Dry Ice pellets have a temperature of
-79°C/110°F and when used for dry ice blasting
immediately change from solid to gaseous form on
contact with the object being cleaned, i.e. the pel-
lets heat up on impact. This change, from solid to
gaseous form, and the accompanying tremendous
expansion in volume, are among the factors which
result in the loosening of impurities.
The transportable dry ice blasting machine
contains a dry ice container and a dispensing unit
which forces the dry ice through a hose to the
blasting gun.
In the gun, the air stream is accelerated and with
it the velocity of the Dry Ice pellets. They leave the
nozzle of the blasting gun at very high velocity and
gain high kinetic energy (movement energy) before
striking the impurities.
The Cleaning Effect of Dry Ice Pellets
The cleaning effect of dry ice is based on
three principles –
•The thermal effect
•The kinetic effect
• Volume expansion
• Thermal Effect:
Dry Ice pellets have a temperature of
-79°C/110°F and impurities are therefore cooled
down drastically: They shrink and loosen.
• Kinetic Effect:
When Dry Ice pellets leave the blasting gun
nozzle they have high kinetic energy; an
important characteristic in removing deposits.
• Sublimation Effect:
When a Dry Ice pellets impacts the object being
cleaned it is immediately transformed from solid
to gaseous form and its volume increases by a
factor of approx. 700. In the process, deposited
dirt become loose and brittle and is torn away
from the underlying surface.
In some cases the thermal effect will be the most
signicant (e.g. where deposits of bitumen, resin,
glue are involved), in other cases the kinetic effect
will be the most signicant (e.g. on brittle deposits).

It is important that operators carefully follow the
safety regulations located on the machine or con-
tained in the manual. Operators must read and un-
derstand the contents of the whole manual before
starting the machine.
The signs located on the machine are to remind
operators that use without risk depends on their
following all regulations, including those describing
work clothing.
Precautions during Blasting
Ai r, CO2gas and Dry Ice pellets leave the gun nozzle
at a very high velocity (up to 300 m/s).
Therefore,
• do not aim the nozzle at persons or in the
direction of places where other people work
• remember that the Dry Ice pellets can be
thrown back from the object being cleaned,
• do not aim the nozzle in directions where
damage might result.
The machine must not be used in “fun” and the gun
nozzle must never be aimed at persons or other
living creatures.
“ Dry ice blasting has some
important advantages over other
cleaning methods. ”
SAFETY REGULATIONS
General
This manual contains instructions and safety regula-
tions which must be followed on starting, operating
and servicing the dry ice blasting machine.
It is important that the manual be kept so that the
operators always know its exact location.
It is also important that the owner makes sure that
operators understand and follow the contents of the
manual.
Personnel Qualications
Personnel responsible for installation, servicing and
maintenance must be suitably qualied to perform
these functions. If personnel are not in possession
of sufcient knowledge they must be instructed and
trained. Such training can be arranged in coopera-
tion with the manufacturer 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 laid down in the following
pages.
The regulations must also be located on the
machine and should be carefully studied.
Security and Risk
The machine is constructed to comply with the
standards and clauses contained in the terms
of sale. Therefore, provided the manufacturer’s
instructions are followed, the machine will not pose
any risk to operators.

MANUAL FOR KG20 KG6 KG6 BASIC
DRY ICE BLASTING EQUIPMENT FROM ICETECH | PAGE 5
CO2Concentrations
The Dry Ice pellets are CO2in solid form. At normal
atmospheric pressure, CO2can only exist in solid
form at temperatures of –79°C/110°F or lower. When
it is used as a blasting medium it becomes heated
and changes into gaseous form. As CO2has a higher
specic gravity than ordinary atmospheric 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 content of in-
haled air being replaced by CO2. Therefore make sure
that the room where such a risk might be present is
well ventilated.
Note that:
•Low CO2concentrations (3-5%) result in
headaches and rapid breathing.
•CO2concentrations of 7-10% produce headaches
and nausea, and may lead to unconsciousness.
•Higher CO2concentrations lead to unconscious-
ness and, in the worst case, suffocation.
As stated above, high CO2concentrations can dis-
place oxygen and result in unconsciousness. There-
fore, avoid using the blasting equipment in spaces/
rooms where ventilation is limited.
Important!
In rooms, closed tanks, etc. with limited ventilation,
the presence of a CO2detector is recommended.
This can be installed to interrupt blasting before the
CO2concentration exceeds a prescribed limit.
“ In many cases cleaning is possible
without dismantling. The frequency of
production stops is therefore often
drastically reduced. ”

Static Electricity
Serious discharge of static electricity can occur.
Always make sure that objects to be cleaned are
adequately earthed and that this connection remains
stable throughout the whole cleaning process.
The dry ice blasting machine is earthed, from ma-
chine cabinet to blasting gun, and through the main
electricity connection on the rear side of the machine
– provided that the machine has been installed as
described under STARTING THE MACHINE pages 16.
Danger of Burns
At atmospheric pressure, CO2in solid form has a
temperature of -79°C/110°F or lower and can give
rise to serious burning on skin contact.
Important!
Therefore, always read the health and safety data
sheet provided by the dry ice supplier, and follow the
instructions given.
Danger of Thrown Loose Objects
There is a risk of dry ice and small objects being
thrown back. Therefore small objects must be rmly
secured before blasting – and loose objects must not
be left in the area where the cleaning process is to
take place.
The operator must always wear approved protective
goggles or a protective shield when working with
the blasting equipment. This also applies to other
personnel in the vicinity of the workspace.
Noise
In order to avoid noise stress, operators must always
wear approved ear protection when working with the
blasting equipment. Because of the high air velocities
in the gun nozzle during dry ice blasting, the level
of noise in the area where operators work can reach
85-115 dB(A). Other personnel in the vicinity must
also be offered ear protection if the noise exceeds
80 dB(A). Ear protection is recommended under all
circumstances. It is important that the work area be
marked with the mandatory signs (blue) showing the
ear protection symbol where the use of ear protection
is required.

Danger of Congelation
When using the blasting equipment, the operator
must wear long-sleeved industrial clothing in order
to eliminate the risk of congelation by contact be-
tween dry ice and unprotected skin.
Read the security card of the dry ice supplier
and follow the instructions given.
Danger of Congelation
When using the blasting equipment, the operator
must wear gloves in order to eliminate the risk of
congelation by contact between dry ice and unpro-
tected skin.
Read the health and safety data sheet of the
dry ice supplier and follow the instructions
given.
Dust
Certain types of dust have a tendency to pulverize
during the cleaning process, and if the amount of
dust developed exceeds 6 mg/m3(ne dust) the
operator must wear a dust mask.
“ When using the blasting equipment,
the operator must wear gloves in order to
eliminate the risk of being burned. ”

“ CO2evaporates back into the
atmosphere, and cleaned-off dirt is
the only remaining waste. There are
no additional blasting media. ”
USING THE MACHINE
The machine is designed to direct a jet of Dry Ice
pellets onto the object to be cleaned and thus
remove impurities from its surfaces.
As the velocity of the cleaning jet is very high and
the temperature of the dry ice (the cleaning medium)
very low, the operator must be very careful to aim
only toward the object being cleaned. Furthermore,
the operator must take every precaution to prevent
either dry ice from the cleaning jet or cleaned-off
impurities from the object striking any persons or
any other plant.
The machine must not be used in surroundings
where there is a danger of explosion. Despite
excellent earthing of both machine and cleaning
object, static electricity can be generated and create
sparking.
The control cabinet (which houses the electrical
controls) must only be opened when the mains con-
nection has been cut off.
The connection between the electrical supply socket
on the blasting gun and the socket on the front of
the machine must only be made after the blast-
ing hose for air/dry ice has been connected at both
ends. When removing the blasting hose from the
machine the electrical supply must be cut off
before hose separation.
MACHINE OPERATION
Via a dispensing system, the machine takes dry ice
from a built-in dry ice tank and into an air stream
which propels it through a hose to the nozzle. The
nozzle is tted into a gun on which a trigger switch is
mounted for cutting off or starting the air/ice stream.
Compressed air supply.
Dry Ice pellets are lled into
the dry ice tank.
Dry ice pellets are dispensed
into the compressed
air stream.
Dry ice pellets are propelled by
the air stream through the
blasting hose.
The blasting gun removes
deposits of impurities.

1 Connect the battery charger.
2 Turn on the battery charger.
3 The recharge starts automatically and the diode
on the battery charger turns yellow.
The diode turns green when the battery is fully
recharged.
The red diode on the battery charger indicates
that the charger is on.
Unplug the charger from the machine and the
100V/220 supply when the battery is fully
charged.
4 Fasten the earth connection wire in the buttery
nut on the back of the machine in order to pre-
vent static electricity. Connect the terminal to
some place already adequately earthed.
5Make sure the machine is on a level, horizontal
foundation.
6Connect the primary air coupling to the main air
connection on the rear of the machine cabinet.
7Plug the blasting hose into the socket on the
front of the machine cabinet. Check that the
hose is securely connected.
8Make the electrical connections at both ends of
the blasting hose with the corresponding sockets
on the blasting gun and on the front of the
machine cabinet.
Dry Ice Check
Dry ice for the cleaning process must be applied
into the built-in dry ice tank. This can be done while
the machine is in operation. It is recommended that
the dry ice tank be run empty for each lling to en-
able the operator to see whether “snow” or lumps
appear in the dry ice. These can prevent a continu-
ous supply of dry ice to the dispensing system.
Never leave the machine with the cover open.
Dry ice must be handled in accordance with the safe-
ty regulations issued by the dry ice supplier, and the
operator must wear personal protection equipment
as described in the above SAFETY REGULATIONS.
The Working Posture of the Operator
Before activating the blasting gun switch, the opera-
tor must stand in a working posture that prevents
loss of balance from blasting gun recoil. When used
at the highest blasting pressure, with the largest
nozzle diameter, the recoil energy can reach as
much as 6 kp. Close off the working area and set up
possible mandatory signs pertaining to ear protec-
tion and safety goggles.
Starting
When the machine has been set up, the following
procedure shall be followed before the cleaning
process is begun:
9Check carefully to ensure that the dispensing
 system at the outow of the dry ice tank is
dry and clean.
10 Open the main pressure air supply (slowly).

“ The operator must not try to
repair the blasting hose. It must be sent
to the manufacturer for repair ”
The outer hose sleeve protects the operator from any
exposure caused by wear and tear of the inner hose.
No pressure is permissible in the outer sleeve during
operation. Therefore, any sign of ination means that
the inner hose is in some way defective. For safety
reasons the machine must then be stopped immedi-
ately and shut down as described above. If a defec-
tive blasting hose is used, the operator risks serious
injury from being hit by Dry Ice pellets.
The operator must not try to repair the blast-
ing hose. It must be sent to the manufacturer
for repair for two reasons:
A) The manufacturer has special tools for making
perfect repairs.
B) In accordance with regulations, a renewed pres-
sure test must be carried out on the hose and a
new pressure test certicate issued.
Never disconnect the blasting hose when the
machine is connected to main electricity and air sup-
plies, otherwise activation of the blasting gun trigger
switch will result in blasting air being discharged
through an open connection instead of through the
gun nozzle. The operator will then loose control of
the air stream and might be seriously injured.
The main electrical connection supplies the battery
charger with 100 V/230 V + 0 + earth (CEE17 plug
with earth). The control circuit uses 24 V.
In the OFF position, the emergency switch cuts off
voltage to the control circuits, but does not make
the machine voltage-free.
The machine is only voltage-free when the battery
is disconnected. Therefore, the control cabinet must
not be opened, and the electrical junction box on
the dosing unit motor must remain closed until the
battery has been removed.
If electrical supply failure occurs the machine will
not start. If the blasting air stream is disconnected
the dry ice dosing unit stops.
Air supply failure stops the blasting air stream
during operation. The air stream decreases and dis-
appears completely when the pressure in the system
falls below 0.5 bar. The main valve for blasting air
closes when the control pressure is below this value.
The dosing unit motor will continue to run for as
long as the trigger switch on the blasting gun is
activated. Therefore, in order to prevent the dispen-
sing unit from being damaged the trigger must be
released no later than when the main valve shuts off
the blasting air stream.
A mesh guard is tted in the dry ice tank to prevent
operators from coming into contact with moving
parts of the dispensing unit during operation. If the
guard is removed, all machine functions stop. On
retting the guard the machine becomes ready to
start without further intervention.
Machine stop caused by guard removal is thus not
an emergency stop demanding machine restart. It
is solely a safety device that automatically activates
when the guard is removed. This stop function must
in no way be modied or bypassed.
