The efficiency of GBS rotary screw blowers remains consistent across the control range, rather than just at certain points – which will make this machine an especially attractive alternative to turbo compressors. This new blower for the low-pressure range draws on Kaeser’s many decades of expertise in the development of highly efficient rotary screw compressors and automation technology, through to smart machines, in order to meet the needs of Industrie 4.0 environments. The new Kaeser rotary screw blowers are up to 35 percent more efficient than conventional rotary lobe blowers, and also deliver significant energy advantages as compared to many other rotary screw blowers and turbo compressors available on the market.
Power transmission from the motor to the compressor is via loss-free, maintenance-free gearing, which means that the GBS impresses with its highly efficient operation and low maintenance requirements. What is more, these machines are designed for space-saving installation and exceptionally quiet operation.
SFC versions feature an integrated frequency converter for dynamic adjustment of the flow rate to actual demand, with frequency converter and motor perfectly matched to deliver consistently optimised overall efficiency. For power outputs up to 110 kW, particularly efficient synchronous reluctance motors are used.
For constant flow rates, the STC version is available, featuring a star-delta starter and energy-saving IE4 Super Premium Efficiency motors.
In order to ensure that predicted high savings are translated into reality, Kaeser guarantees the power consumption per unit of flow rate (specific power consumption in kW per m³/h) in accordance with the narrow tolerances of ISO 1217, Annexe E. Customers therefore enjoy the peace of mind that comes with guaranteed accuracy of the projected savings and amortisation periods.
The integrated Sigma Control 2 controller ensures operational reliability and smart communication via integration into process control systems, including those with Industrie 4.0 requirements. The Sigma Air Manager 4.0 master controller is recommended for blower stations with multiple blowers, as it features control and regulation algorithms specially developed for the needs of low-pressure applications. This enables even greater energy savings and simplification of automation.
Applications with especially high energy requirements, such as the production of air for aeration in wastewater treatment facilities and bioreactors, as well as for flotation and fluidisation, are sure to benefit from this advanced automation and compressor technology from Kaeser.
Established in 1919 as a mechanical engineering workshop, Kaeser Kompressoren is a family-owned business and today is one of the world’s leading compressor manufacturers and compressed air systems providers. Kaeser’s production centres are located in Coburg (main plant) and Gera, Germany. The company approximately 7000 employees worldwide.
Kaeser’s comprehensive product range comprises stationary and portable rotary screw compressors, stationary and mobile reciprocating compressors, vacuum pumps, rotary blowers, rotary screw blowers, turbo blowers, filters, dryers, air tools and accessories. Furthermore, Kaeser’s state-of-the-art compressor control systems with advanced IT technology take compressed air efficiency to the next level and beyond. Both users and the environment therefore benefit from the consequent energy-savings.
Subsidiaries and authorised partners in over 140 countries ensure that users are able to enjoy all of the benefits that the very best in compressed air engineering has to offer. Key markets include the EU, the United States, Latin America and the Asia-Pacific region. Kaeser owes its enviable reputation not only to the exceptional efficiency and quality of its products, but also to its reliable field service. More recently, the other industry-leading services offered by the company – such as operator models for compressed air stations, concepts within the framework of Industry 4.0 and predictive maintenance – have increasingly moved to centre stage.
Kaeser’s many years of strong growth and expansion are directly attributable to its passion for innovation and strict quality standards. Both are driven by the hard work and dedication of its employees, whose expertise, combined with ongoing professional development, keep them attuned to the very latest technology. The company’s opening-up of key global markets in recent years has also created many additional jobs and secured existing ones, both in Germany and around the world.
The company is headed by Thomas Kaeser, Dipl.-Wirtsch.-Ing, grandson of the company’s founder, and Tina-Maria Vlantoussi-Kaeser, Dipl.-Wirtsch.-Ing.
