- SIEMENS induction turbines have neither ports in
connection nor transmissions. The motors involved are
three-phase induction with side-channel blowing engine.
The average rotation speed is 2,850 rpm (revolutions
per minute], in contrast to 20,000 rpm of a traditional
single-phase motors. This difference means that there is
much lower stress for the shafts and bearings. The motor
is powered by induction: there are no carbon brushes,
sparks, or other components in friction. These motors do
not need maintenance, they were developed for professional
use and they are routinely used by industries
for continuous duty (24 hours, every day) with reliable
characteristics. These motors cannot be compared with
a traditional vacuum system and they ore the highest
technology on the market.
- STAR FILTER mode of special polyester cloth with high
withholding properties which is one of the most highly
appreciated components of the DISAN system. All the
industrial vacuum units use this type of filter, it combines
a high withholding of micro dust with easy-cleaning.
Cleaning can be accomplished by shaking or machine
washing. Different filter medium are available to provide
required BIA. The optional and recommended self-cleaning
system always maintains the maximum efficiency. This
system automatically cleans the filler at pre-programmed
intervals (typically once per day). The filter chamber has
a large surface and so it is easily inspectional.
- The motors con be equipped with an ELECTRONIC INVERTER
so the motor can automatically adopt the power
(and the consumption) according to the number of simultaneous
operators and the filtering surface efficiency. An
electronic transducer for vacuum measurement located
in the central unit maintains the optimal operative vacuum
level (Default 140mbar, 56inH20). When the
vacuum is too high the system lowers the motor rpm and
as a result the power consumption is reduced. When the
vacuum is too tow Ihe system increases the motor rpm
and increases the vacuum level and airflow. Electromagnetic
shielding type B (for private applications) and is
provided with certificate to ovoid electromagnetic interference
issues. The prime advantage of the inverter is an
economical way to proportion electric power consumption
to the ever changing system needs.
- ELECTRIC CONTROL BOX is provided with
IP55 safety degree, in accordance with CEI.
Magnetic-thermal protection, control display, selector
switch for automatic or manual, and startriangle
starting for motors with more than 2.2
kW are also provided for operational control.
- REMOTE CONTROL DISPLAY.
The advantoge of a programmable
control system is that it allows
to control and modification of the
motor power. Furthermore can
display trouble alerts. The PLC (Programmable Logic Circuits)
card used is a Siemens S7200, which interfaces
with a Profibus protocol so that it could be integrated
with a pre-existing bus network. As an option it provides
a “touch screen” system control away from the power
and filtering units.
- DUST CONTAINER with cushioned fasteners for on
airtight and easy closure. High capacity dust container
in ABS: it requires to be emptied out only once/twice a
year. The check level window permits one to check when
the single use plastic bag must be replaced. The collect
and the elimination of the dust can be done without any
contact and by using the wheels. The optional system of
compensation pressure at the dust container is available.
- CONNECTION ELEMENTS and mounting elements ore always included The DISAN central units ore always
furnished complete to be installed without the necessity to buy collectors, couplings, or other installation materials
The great advantage of the central units with electronic control is that they are always ready for the
starting simply by connecting the plug at the current network All the connection couplings at the solid piping
(me ore anti-vibration and adjustable.
OPEN FRAME steet motor mounts ore for maximum dissipation of heat. The opened (rome does not imply o
higher sound level as 90% of the sound is from the exhaust (discharge). The system is provided with a exhaust
silencer to minimize sound level The largest advantage of the open frame is the increase in thermal dissipation,
the increase in performance efficiency, and cancellation of the risk of motor fusion The motors, are on fixed
basis at tower mounting for space saving
