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. 

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.
