KAESER schroefblowers

EBS Rotary Screw Blowers

The EBS 410 rotary screw blower from Kaeser represents a new milestone in the development of oil-free compression blower technology, designed especially with water industry applications in mind. With a flow rate of 10 – 40 m³/min and pressure differentials from 0.3 to 1.1, as well as a selection of motors ranging from 22 to 75 kW, the innovative EBS 410 sets new standards in terms of energy efficiency, space-saving design and automation. The SFC version is equipped with a frequency converter and a synchronous reluctance motor – a slip-free design that combines all the advantages of high efficiency permanent-magnet motors with those of robust, service-friendly asynchronous motors. Thanks to variable speed control, the flow rate can be adjusted as required and a control range of 1:4 is achieved, which allows exceptionally dynamic operation. The STC version is now equipped with an energy-saving IE4 Super Premium Efficiency motor that reduces energy consumption and therefore costs, making the STC version more efficient than ever before. With both versions, power transmission from the motor to the airend takes place via loss-free and maintenance-free gearing, which results in an up to 8 % improvement in specific power compared to the previous model. The complete machine achieves an isentropic efficiency of up to 80%, representing the pinnacle of performance for oil-free compression machines. In order to ensure that the specified performance figures are translated into reality, Kaeser guarantees performance in accordance with the strict tolerances of the ISO 1217-C/E standard.

FBS rotary screw blowers

The FBS rotary screw blower from Kaeser represents the next milestone in the development of oil-free compression blower technology. With a flow rate of 18 to 72 m³/min and pressure differentials from 0.3 to 1.1 bar, as well as a selection of motors ranging from 45 to 110 kW, the innovative FBS continues the success story of its smaller sibling, the EBS, whilst setting new standards in terms of energy efficiency, space-saving design and automation. The SFC version is equipped with a frequency converter and a synchronous reluctance motor – a slip-free design that combines all the advantages of high-efficiency permanent-magnet motors with those of robust, service-friendly asynchronous motors. Thanks to variable speed control, the flow rate can be adjusted as required and a control range of 1:4 is achieved, allowing exceptionally dynamic operation. The fixed speed STC version is equipped with an energy-saving IE4 Super Premium Efficiency motor, which reduces energy consumption and therefore costs, making the STC version more efficient than ever before. On both versions, power transmission from the motor to the airend takes place via loss-free and maintenance-free gearing, which results in an improvement of up to 7% in specific package input power as compared to the previous model. The complete machine achieves an efficiency range that represents the pinnacle of performance for this particular segment. In order to ensure that the specified performance figures are translated into reality, Kaeser guarantees performance in accordance with the strict tolerances of the ISO 1217-C/E standard. FBS rotary screw blowers are delivered ready for immediate connection, including controller and frequency converter or star-delta starter. All units are CE and EMC-certified, thereby minimising the planning, construction, certification, documentation and commissioning costs for planners, operators and plant manufacturers.

GBS rotary screw blowers

Peak performance at high flow rates GBS rotary screw blowers set a new benchmark in compressor technology for the 75 to 160 kW power range, with a flow rate from 22 to 104 m³/min and differential pressures up to 1100 mbar. These machines not only feature exceptional control characteristics, quiet operation, an optimised footprint and low maintenance requirements – they also deliver consistently high efficiency across the entire control range. 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.
