lowing regulations and directives are
applicable in the Federal Republic of
Germany (available from Carl Hey-
manns Verlag KG, Luxemburger

– BGV D 26 Spray jet tasks
– Executing instructions for BGV D 26

Î Release the trigger of the jet pistol.
Î Press emergency-stop button.
The dry ice dosing is topped and the air
flow from the nozzle is interrupted.
Î Interrupt the compressed air supply.
The machine is used to remove dirt us-
ing dry ice pellets that are speeded up
using an air jet.
The machine should not be operated in
explosive environments.
Use only dry ice pellets as jet medium.
Using any other jet medium can cause
damage 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 pistol. Additionally, dry
ice pellets are dosaged into the air
stream via the dosing device. With the
version "IB 7/40 Advanced" the addi-
tional dosing can be switched off at the
jet pistol. The dry ice pellets hit the sur-
face to be cleaned and remove the dirt.
Additional heat currents are formed be-
tween the dirt and the object to be
cleaned by the -79 °C cold dry ice pel-
lets; this results in the dirt being loos-
ened. At the same time, dry ice
immediately gets coverted into gas-
eous carbon dioxide on contact and re-
quires 700 times the volume of dry ice.
Thus, the dirt penetrated by the dry ice
thus gets thrown off.
During the spraying operation through
the jet, a vibrator located on the dry ice
container ensures continuous sliding of
the dry ice pellets.
