The three-phase DISAN for professional range is synonym of quality and innovative technique with unequal characteristics of resistance and reliability in the long run.
SIEMENS induction turbines have neither parts 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 are the highest technology on the market.
The motors can be equipped with an electronic inverter so the motor can automatically adapt 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, 56inH2O). 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 low the 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 avoid electromagnetic interference issues. The prime advantage of the inverter is an economical way to proportion electric power consumption to the ever changing system needs
Remote control display. The advantage 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.
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 star-triangle starting for motors with more than 2.2 kW are also provided for operational control.
Connection elements and mounting elements are always included. The DISAN central units are 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 line are anti-vibration and adjustable.
Star filter made 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 filter at pre-programmed intervals (typically once per day). The filter chamber has a large surface and so it is easily inspectional.
Dust container with cushioned fasteners for an 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.
Open frame steel motor mounts are for maximum dissipation of heat. The opened frame does not imply a 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.
