CDX
The CDX explosion-proof vibrators
have been designed for use in indu-
strial processes in a potentially explosi-
ve atmosphere.
The enclosure of the CDX vibrators is
equipped with increased thickness and
joints to prevent the transmission of an
internal explosion to the surrounding
area.
The CDX series is characterized and
enhanced by many different certifi-
cations, depending on the vibrator
model.
