GENERAL INFORMATION
The Evolution Line manual is for the Elite 20 and the Xtreme 40 dry ice blasting
machines produced by IceTech. IceTech machines and accessories have been
developed to supply 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 (similar to sand blasting), AND a
thermal cleaning process (familiar in steam cleaning). The blasting media itself (dry
ice pellets) sublimates; 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”particles” 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. 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
compressed 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.

7
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 the contaminant.
SAFETY REGULATIONS
GENERAL
This manual contains instructions and safety regulations which must be followed
while starting, operating 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 contents of the manual.
PERSONNEL QUALIFICATIONS
Personnel responsible for operation, servicing and maintenance must be suitably
qualied to perform these functions. Special training in machine handling as well
as in repair and maintenance is offered by 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 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, provided the
manufacturer’s instructions are followed, the machine will not pose any risk to the
operator.

8
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.
STATIC ELECTRICITY
Serious discharge of static electricity can occur. Always
make sure that objects to be cleaned are adequately
earthed/grounded and that this earthing/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 Machine” on page 16.
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 surroundings where
there is a danger of explosion. Despite optimum earthing/
grounding of both machine and cleaning object, static
electricity can be generated and create a spark.

9
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.
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 before 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.
DUST
Certain types of dust have a tendency to accumulate during
the cleaning process. Therefore we recommend that the
operator wears a dust mask or if necessary a breathing
mask and industrial protective clothing.
PROTECTIVE CLOTHING
When using the dry ice blasting machine, the operator must
wear long-sleeved industrial protective clothing and gloves
in order to eliminate the risk of congelation when the dry ice
comes in contact with unprotected skin.

10
CO2DETECTOR
The presence of a CO2detector is recommended in areas of
limited ventilation such as rooms, closed tanks, etc. The CO2
detector can be installed to interrupt the blasting process
before the CO2concentration 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 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
inhaled air being replaced by CO2. Therefore it is essential to
make sure the room is well ventilated when dry ice blasting!
LOW CO2
• 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 unconsciousness 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.
Read the safety data sheet provided by the dry ice supplier
and follow the instructions given.

STARTING
When the machine has been set up as described above (points 1-5), the following
procedure shall be followed before the cleaning process has begun:

18
9. Check to make sure that the machine is in the normal
operating position (the emergency stop button is pulled
out).
10. Turn the machine ON (press the ON/OFF button).
11. Lift the lock pin and activate the trigger on the blasting
gun for a few seconds to allow air to ow through the
system. This checks for moisture in the airstream
and proper operation of the dosing disc, vibrator, and
regulator.
12. Fill dry ice pellets into the hopper (this can be done
while the machine is in operation).
Please note: It is recommended that you run
the hopper empty before each lling to enable
the operator to see whether “snow” or lumps
appear in the dry ice. These can prevent a
continuous supply of dry ice to the dosing unit.
Never leave the machine with the lid open.

19
13. Adjust the dry ice consumption (kg/h / lb/min.) and the
blasting pressure (bar/psi) – the value is shown on the
pressure gauge.
15. “Light button” (only when machine is equipped with a
light gun) – to improve visibility during blasting turn on
the “Light button” on the control panel.
16. “Empty hopper function” (*available only for Xtreme 40)
– if there are residues of dry ice in the hopper, push the
button for 3 sec. to start the empty hopper cycle.
17. “Empty hopper function” (*available only for Xtreme 40) can also be used
in an emergency situation when a foreign object enter the dosing unit. By
pressing the button for 1-2 seconds you can move the dosing disc counter-
clockwise by a small degree which will allow for the removal of the object.
14. Start dry ice blasting.
NB Please note: Before activating the blasting
gun switch, the operator must be in a safe and
stable working position. Depending on the jet
pressure, the recoil on the jet gun also changes.
At the highest jet pressure with the largest
nozzle diameter, the recoil force can amount to
10 kg / 22 lbs, which is why it is ensured that the
operator does not lose balance.

20
SHUTTING DOWN THE DRY ICE BLASTING MACHINE
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 or use the air release valve.
• Turn off the machine (press the ON/OFF button).
• Disconnect the main power supply.
• Open the air release valve to depressure the air side 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. Before the machine can be restarted, the following procedure
must be carried out:
• Disengage the emergency stop button (twist and release the button).
• Start the machine (press the ON/OFF button).
• Restart the blasting air stream by activating the trigger switch on the blasting
gun.
