KAESER rotary screw blowers also masterfully manage the balancing act between best possible damping of structure-borne and fluid-borne noise and optimised cooling of the blower airend, drive motor and intake air. In fact, the reduction of fluid-borne noise – pulsations caused by the com

pressed process air conveyed in the connected piping – has been refined to perfection. Compressed air at the push of a button Guaranteed performance specifications KAESER rotary screw blowers are user-friendly turnkey systems, delivered ready for immediate operation. All that is needed is to connect them to a power supply and the air network. The arduous processes of oil-filling, drive belt installation, motor adjustment, procurement of a suitable frequency converter, programming, cabling in accordance with EMC regulations, drawing circuit diagrams, arranging CE and EMC certification, etc. are thankfully consigned to the past. To ensure that the projected savings are actually achieved during operation, KAESER quotes effective overall power consumption figures, as well as the usable flow rate, in accordance with the stringent tolerances of ISO 1217, Annexe C or E (as applicable). Procuring complete, certified machines from systems manufacturers ultimately saves you both time and

money, whilst guaranteeing many years of reliable operation. Super Premium Efficiency motors KAESER rotary screw blowers with flange motors are now equipped with Super Premium Efficiency motors (IE4 and IES2), which stand out for their high energy-saving potential thanks to extremely high levels of efficiency. Saving money has never been so easy! 1217:2009 3 4 CBS, DBS, EBS, FBS, HBS series Pure efficiency with the SIGMA PROFILE Developed in the early 1970s, KAESER’s SIGMA PROFILE rotor technology revolutionised rotary screw compressor energy efficiency. Continually refined ever since at KAESER’s Research and Development Centres in Coburg and Gera, this high-efficiency compressor technology is now available for use in blower systems as well. Blower airend with SIGMA PROFILE Dependable seals KAESER’s high-efficiency blower airends combine a wide control range with near-constant specific package input power. Equipped with energy-efficient SIGMA PROFILE rotors, they ensu

re maximum air delivery whilst keeping power consumption to an absolute minimum. Field-proven in KAESER rotary screw compressors, the sliding ring seal for the rotary transmission drive shaft lead-through on the blower airend housing is completely maintenance-free and guarantees dependable sealing performance, even in hot or dusty environments. Durable bearings Continuous system monitoring Four robust cylinder roller bearings absorb 100% of the radial forces, thereby ensuring a long service life for the airend. The rolling elements are encased in high-tech cages for optimum lubrication at all speeds. Sensors for oil level and temperature monitoring are integrated into the blower airend. The inside of the oil chamber is designed to ensure these continue to function whilst the machine is operating – even with fluctuating oil levels. Clever cooling design means KAESER rotary screw blowers require minimal oil. 5 CBS to HBS series Direct drive – Ultimate efficiency In CBS to G

BS series rotary screw blowers, power is transferred from the motor to the blower airend via a lossless and maintenance-free gear transmission. This has proven to be the best solution for the prevailing speeds in this performance and size class when it comes to efficiency, reliability and durability. With HBS series blowers, power is transferred directly without loss via a coupling. These concepts were the result of extensive research at KAESER’s Research and Development Centres. The transmission ratio can be varied using different sets of timing gears, so that for example, the motor can be used at all times within the optimum frequency range of the SFC’s variable speed control, or in the case of fixed-speed operation, flow rate can be matched to actual demand. Moreover, the combination of low lateral forces on the motor shaft and low-speed operation helps to ensure a long service life for the motor bearings. 6 Electric motor Airend with SIGMA PROFILE SIGMA B blower airend Prov

iding exceptional efficiency and optimum reliability, the airend does not require any auxiliary equipment, such as an oil or vacuum pump, or an oil cooler. CBS to GBS series from 7.5 to 110 kW Pure efficiency with synchronous reluctance motors High-efficiency synchronous reluctance motor High-performance frequency converter As a slip-free motor, this design combines all the benefits of high-efficiency permanent-magnet motors with those of robust, maintenance-friendly asynchronous motors. No aluminium, copper or expensive rare-earth magnets are used for the rotors. Instead, they are constructed from electrical steel with a specialised profile and arranged in series. This makes the drive highly durable and easy to service. The Siemens frequency converter uses a control algorithm that is specifically adapted to the motor. With the perfectly matched combination of frequency converter and synchronous reluctance motor, KAESER achieves the highest possible system efficiency class of IE

S2 as per IEC 61800-9-2. Low magnetic resistance High magnetic resistance How the reluctance motor works High efficiency in partial load operation In a synchronous reluctance motor, the torque is generated by magnetic reluctance forces. The rotor features salient poles and is made of a soft magnetic material, such as electrical steel, which is highly permeable to magnetic fields. Synchronous reluctance motors achieve significantly higher efficiency in the partial load range than asynchronous motors. This helps achieve savings of up to 10% compared with conventional variable-speed systems. 7 CBS to HBS series Efficient and dependable The blower airend plays a key role in ensuring outstanding energy efficiency. It achieves this in combination with carefully matched components and the advanced SIGMA CONTROL 2 blower controller. 0.014bar 0.014bar 107.8m /min Lauf: 2h 66% 0.482bar 15 C 3003rpm 68 C Wartung in: 2997h The blower controller Comprehensive sensors The SIGMA CONT

ROL 2 ensures efficient blower control and system monitoring at all times. A readout display, RFID reader and numerous interfaces enable fast and reliable communication, whilst the SD card slot makes data storage and software updates a breeze. In the event of a failure of the master control system, the blower will switch automatically to individual operation and can be controlled manually – ensuring a continued supply of quality compressed air for the applicable process. A wide range of sensors and switches for monitoring pressure, temperature, speed, oil level and filters ensures dependable operation of the blower, whilst allowing remote monitoring and visualisation of operating status. Specific package input power (kW/m³/min) Conventional speed control Efficient SFC variable speed control Flow rate (m³/min) 8 Cool intake air Optimised specific package input power Process air and cooling air for the motor are drawn in separately from outside the sound enclosure. This boos

ts efficiency and leads to a higher usable mass flow rate for the same power consumption. The blowers can operate in ambient temperatures up to +45°C. The moderate maximum speed, an extra-dense screw profile and near-constant specific package input power across a wide, variable-speed control range all combine to achieve significant energy savings across the entire operating curve. 9 10 CBS to HBS series Plug-and-play KAESER rotary screw blowers are delivered as turnkey complete machines, which saves operators a time-consuming and cost-intensive installation procedure. Moreover, they are supplied ex-works ready for integration into Industrie 4.0 applications. START CONTROL (STC) SIGMA FREQUENCY CONTROL (SFC) The version with integrated star-delta starter for constant-speed operation is equipped with a premium contactor, overcurrent relay and phase monitoring.

ies rotary screw blowers not only impress with their energy-saving drive concept, but also with their well thought-out and compact design, which allows all maintenance work to be performed from the front. Side-by-side installation is possible even with all electrical equipment. Since they provide even more power, the larger GBS and HBS machines require more installation space. A certain minimum clearance distance is therefore required to ensure sufficient service accessibility. DBS footprint only 1.65 m² 12 Outstandingly compact Side-by-side installation Comprising a blower airend with drive motor, loss-free power transmission, silencers, sensors, controller and electrical equipment such as frequency converter or star-delta starter, this compact powerhouse features a footprint of just 1.65 m² (DBS), whilst the fully automated 75 kW EBS blower model boasts a footprint of only 2.5 m². The package layout of CBS to FBS series rotary screw blowers has been designed to allow all mai

ntenance work to be performed from the front of the unit. These compact blowers can therefore be installed side-by-side without the need for any additional work. Flow-optimised Even quieter All relevant components, including on the intake side, are flow-optimised to minimise pressure losses. Silencers, air filters and non-return flaps also help us to stay true to our motto of providing “More compressed air for less energy”. Highly effective sound damping not only minimises machine noise via the sound enclosure; special absorption silencers also help significantly to reduce fluid-borne noise transmitted through the piping – a characteristic commonly associated with speed-controlled blowers.

Further optimisation SIGMA AIR MANAGER 4.0 The SIGMA CONTROL 2 internal compressor / blower controller and the SIGMA AIR MANAGER 4.0 master controller provide more than just optimis

ed blower air system efficiency. Thanks to their high level of data integration and multiple interface options, they can be easily integrated into advanced production, building management and energy management systems, as well as Industrie 4.0 application environments. Optimum conditions Heat recovery Cooler Carefully matched peripheral components, such as weather protection screens, supplementary fans and sound dampers in the inlet and outlet ducting, help maintain a pleasant working environment. Heat exchangers can cool the process air significantly, even at high ambient temperatures. The heat gained can therefore be utilised for the purposes of space heating and/ or water heating, thereby considerably reducing primary energy costs. With minimal differential pressure, the economical ACA-type air/air aftercooler uses a temperature switch to limit the blower air temperature reliably to 10 Kelvin above ambient. 17 Layout 01) SIGMA CONTROL 2 controller 02) STC or SFC control
