Speed-controlled all-in-one systems

Kaeser, Hall 4 Booth 441

Boosters are needed when, for production-related reasons, compressed air is required at a higher pressure than network pressure. Kaeser’s new boosters provide the ideal solution for compressed air users in the brewery industry who require higher pressure air. As the first all-in-one booster system, the DNC series from Kaeser is now also available with variable speed control and with motor powers from 22-45 kW. As a result, the compressor flow rate is matched to actual air demand, which means that only as much energy is consumed as is needed to produce the supply of higher pressure compressed air. The system is therefore also especially efficient in the partial load range since the compressor switches to idle operation when air demand drops below the control range. Compressor operating speed and energy consumption are consequently kept to a minimum.

With a motor capacity of 7.5-22 kW and flow rates of 2.3-12.2 m³/min, the CBS rotary screw blower provides the perfect solution for users, for example, who require air for wastewater treatment in operational clarification plants with a pressure differential of up to 1,100 mbar. The blower also shines through with its many benefits when it comes to liquid aeration, flotation, fluidisation and bioreactor applications. It is stated to be up to 35 per cent more efficient than comparable conventional rotary lobe blowers and to offer significant energy advantages in the double-digit range compared with many other rotary screw blowers on the market. In fact, a rotary screw blower is so powerful that it can easily and effectively cover the control range of two to three rotary lobe blowers.
