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.
Power supply
Three-phase voltage from 24V to 690V
(limit at 600V for UL and CSA certifications),
50Hz or 60Hz, or single-phase 100-130V
60Hz and 200-240V 50Hz; suitable for use
with a PWM inverter from 20Hz to the
base frequency with constant torque load
profile.
Polarity
2, 4, 6 and 8 poles.
Reference Regulations and Directives
See table below.
Controls
The components that affect protection
are 100% accurately controlled and
recorded.
Functioning
Continual service (S1) at maximum decla-
red centrifugal force and electric power.
Intermittent services are also possible
depending on the type of vibrator and the
operating conditions. For detailed infor-
mation, contact our technical assistance
office.
Centrifugal force
Range extended to 22400 Kgf. (220 KN),
with centrifugal force adjustable from 0
to 100%.
Mechanical protection
Mechanical protection IP66 according to
IEC 529, EN 60529.
Protection against mechanical impacts
IK 08 according to IEC 68, EN 50102.
Insulation class
Class F (155°C).
Tropicalization
Standard on all vibrators, with vacuum
encapsulation up to size 35, with “drop
by drop” trickle system for larger sizes.
Ambient temperature
From -20°C to +40°C.
Vibrator thermal protection
With thermal protector at 130°C for the
entire CDX range, or on request with PTC
thermistors rated heat detectors 130°C
(DIN 44081-44082).
Fixing of the vibrator
In all positions and therefore without
restriction.
Lubrication
All vibrators are lubricated in the factory
and do not require further lubrication
if used in normal operating conditions
(“FOR LIFE” lubrication). In heavy duty
operating conditions periodical re-
lubrication may be applied to size 40 and
larger.
Terminal box
Large fixed electrical connections. The
terminal cover, with increased thickness,
is constructed to contain internal explo-
sions. Special shaped terminals allow to
fix the power supply cable, protecting it
from loosening.
Electric motor
Three-phase and single-phase asyn-
chronous type. Designed for maximum
starting torques and torque curves
specific to requirements of the vibrating
machines. Insulated windings using vacu-
um encapsulating up to size 35; using the
“drop by drop” trickle system with Class H
resin for the larger sizes. The rotor is die
cast aluminium.
Casing
In high-tensile aluminium alloy up to size
30, in spheroidal cast iron for larger sizes.
Patented shape that improves heat
dispersion and lowers normal running
temperature with full load.
An external earthing screw is located on
the casing as prescribed by Regulation
IEC/EN 60079-0.
Bearing flange
Constructed in spheroidal or grey cast
iron.
The geometry of the flange transmits the
load to the casing uniformly.
Bearings
Custom made with particular geome-
try, especially designed for Italvibras,
suitable to support both high radial and
axial loads.
