The low pressure experts

Coburg, 27.02.2020 (PresseBox) – Kaeser blowers are the perfect example of the efficiency and future-oriented approach for which this Coburg-based compressed air specialist is renowned. At IFAT 2020 in Munich, the company will be showcasing solutions for every possible low-pressure application; not just high-efficiency rotary screw blowers – now fitted with synchronous reluctance motors – but also, for the first time, turbo blowers. Of course, the icing on the cake is the Sigma Air Manager 4.0 master controller, which binds multiple blower units together into a single, unified team that is simple and intuitive to operate.
For wastewater treatment systems in either communal or industrial treatment plants, bioreactors or flotation plants, operators seeking a reliable supply of compressed air with differential pressures up to 1100 millibar and a flow rate from 5 to 160 m³/min need look no further than Kaeser’s rotary screw blowers from the CBS to HBS series, featuring a power output of 7.5 – 250 kW. Up to 35% more efficient than conventional rotary lobe blowers, they also offer significant advantages in terms of energy efficiency and blower air availability when compared to many of the turbo blowers available in this power range. Kaeser rotary screw blowers particularly excel when operating at 100% duty cycles, where they are especially well suited to generating process air for the purposes of aeration in water treatment, flotation and fluidisation processes and in bioreactors.
High-efficiency motors
Kaeser’s latest generation of variable-speed rotary screw blowers is equipped as standard with synchronous reluctance motors – highly efficient drive motors that are able significantly to boost the energy efficiency levels of units equipped with a frequency converter. The special rotor design used in this new generation of motors makes them extremely robust and durable. Furthermore, all Kaeser blowers are delivered as complete, turnkey machines including a Sigma Control 2 smart controller, which makes them particularly well suited to Water 4.0 applications.
Turbo blowers now available from Kaeser
The latest member of the Kaeser family is the PillAerator turbo blower, suitable for flow rates of 50 – 275 m³/min and differential pressures up to 1.3 bar. These extremely energy-efficient machines stand out for their intelligent design, whereby smart magnet bearings operate completely wear-free, pro-actively controlling the position of the rotors. Furthermore, they are completely safeguarded against any potential power failure. As the bearings operate completely independently of speed, the machine is always ready for re-starts, whilst the use of a cooling concept for core components that does not rely on ambient air ensures a particularly long-lasting and trouble-free operation.
For a modern, professional blower station, the Sigma Air Manager 4.0 master controller is an absolute must. Not only does it ensure optimal operation of each individual blower unit, but also that all units are operating together as a system in the most energy-efficient manner possible. Upon specifying the required setpoints for intake flow volume, standard flow volume or working pressure via the process control system, the Sigma Air Manager 4.0 then orchestrates the most efficient possible air supply and optimal load operation for each individual blower within the system. The operating data provided by SAM can further serve as a basis for an energy management system as per DIN EN ISO 50001 and DWA A 216.
