Danger
Risk of injury on account of flying objects.
Fix light cleaning objects properly to pre-
vent them from being dragged off with the
dry ice jet.
Warning
Danger of crushing on account of the dos-
ing equipment. Always remove the ma-
chine plug from the socket before removing
the protective shield of the dry ice contain-
er.

Proper use

The machine is used to remove dirt using
dry ice pellets that are speeded up using an
air jet.
The machine should not be operated in ex-
plosive environments.
Use only dry ice pellets as jet medium. Us-
ing any other jet medium can cause dam-
age to the machine.

Function

The air pressure reaches the jet pistol via a
pressure regulation valve. The valve opens
when the trigger of the jet pistol is pressed
and the air flow comes out from the jet pis-
tol. Additionally, dry ice pellets are dosed
into the air jet via the dosing device. The
additional dosing can be switched off by
means of the operating mode switch. The
dry ice pellets hit the surface to be cleaned
and remove the dirt. Additional thermal
stress occurs between the dirt and the ob-
ject to be cleaned due to the -79 °C cold dry
ice pellets; this contributes to the removal
of the dirt. At the same time, dry ice imme-
diately gets coverted into gaseous carbon
dioxide on contact and requires 700 times
the volume of dry ice. Thus, the dirt pene-
trated by the dry ice thus gets thrown off.
During the spraying operation through the
jet, a vibrator located on the dry ice contain-
er ensures continuous sliding of the dry ice
pellets.
