IFAT 2018: Innovative Low-Pressure Solutions

Extremely efficient and future-oriented – Kaeser blowers for water treatment applications in the era of Industrie 4.0. At this year’s IFAT, renowned compressed air specialist provider Kaeser Kompressoren will showcase innovative solutions for the low-pressure range. These include two new models in the company’s successful screw blower series: one large and one small machine for the scope of application previously covered by turbo compressors. And to round out the showcase, a versatile master controller that harnesses the power of multiple blowers into an easy to control and highly effective team.


Rotary screw technology for blowers from Kaeser: the powerful CBS series delivers quiet operation and saves energy costs.


For municipal or industrial wastewater treatment plants requiring compressed air with differential pressures up to 1100 mbar and flow rates from 2.3 to 12.2 m³/min, the CBS screw blower is the perfect solution – with power from 7.5 to 22 kW. It’s up to 35 percent more efficient than conventional rotary blowers and even offers significant energy advantages in the two-digit range compared to other screw blowers on the market. The advantages of the CBS series shine especially in continuous operation, making it ideal for applications such as production of aeration air in water treatment and for bioreactors, flotation and fluidisation.

On the high-power end, the HBS screw blower sets a new benchmark for compressor technology in the 132 to 250 kW power range, with flow rates from 60 to 160 m³/min. With exceptional controllability, whisper-quiet operation, low maintenance requirement – and an optimised footprint – the HBS delivers consistent high efficiency across virtually the entire control range, rather than just small part of it. This feature makes the HBS an attractive alternative to turbo compressors in particular.

Of course, both blowers, the CBS and HBS, are complete machines ready for connection, equipped with the Sigma Control 2 smart controller and independent monitoring.

Although the Sigma Air Manager 4.0 master controller does ensure efficient operation of the individual blowers, its primary advantage is to optimally coordinate all of them together in simultaneous operation to achieve the highest possible efficiency. This master controller is therefore the solution for optimal automation of blower stations. Simply input the desired target value for flow rate or working pressure into the process control system and the Sigma Air Manager 4.0 immediately calculates how to achieve optimal operation of each individual blower. Simultaneous operation of multiple blowers is therefore not only efficient in the partial load range, but is now even easier thanks to clear interfaces and is more effective due to equal machine loading.

Kaeser Kompressoren will be present at the IFAT (held from May 14 to May 18, 2018 in München) in Hall A1, Stand 143/242 (main booth) and in Hall C3, Booth 133 (portable compressors).
