Efficient pressure performance up to 45 bar!

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.

The DNC SFC system is delivered ready to connect complete with sensors and frequency converter.  All systems are CE and EMC certified and thereby minimise planning, construction, certification, documentation and commissioning cost for operators and equipment manufacturers.  The efficient compressor unit, the compact enclosure and the entire electrical system are mounted on a space-saving base frame. Moreover, the highly effective sound insulation panelling helps ensure low-noise operation with low compressed air discharge temperatures. Connection of the booster system to an advanced master controller, such as the Sigma Air Manager 4.0, is made possible by the integrated Sigma Control 2 controller. This technology also enables integration of the booster package into Industrie 4.0 production environments.

Kaeser’s new CNC series machines are the ideal choice for breweries with smaller air delivery requirements. With motor capacity from 7 to 22 kW, they will also be available both as standard and frequency-controlled versions in all power ratings.

Efficient solutions in the low pressure range

With a motor capacity of 7.5 to 22 kW and flow rates of 2.3 to 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 1100 mbar. The blower also shines through with its many benefits when it comes to liquid aeration, flotation, fluidisation and bioreactor applications.  It is up to 35 percent more efficient than comparable conventional rotary lobe blowers and even offers 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.
