Double the benefits with Kaeser's latest generation HSD series rotary screw compressor systems
The HSD series rotary screw compressor systems are ideal for applications that require large volumes of quality compressed air with a small footprint. The two self-contained compressors are both installed within a single housing that is no larger than a single compressor!
System availability is optimised with the HSD series from Kaeser. Each compressor section operates completely independently from the other. This means that performance can be precisely adjusted to suit requirement and costly idling can be kept to an absolute minimum.
The modern design behind the latest generation model, uses standard components and simple, cost-effective 1:1 direct drive systems to achieve superior efficiency and reliability. The drive motor and the compressor block are linked via a maintenance free coupling. This avoids the transmission losses associated with gear driven units. The benefits speak for themselves; efficient power transmission, optimal energy consumption and reduced servicing and downtime costs.
Each rotary screw compressor found in the HSD series systems feature a super-premium efficiency IE4-rated drive motor. Currently the most efficient motor available, IE4-rated drive motors comply with and exceed prevailing Australian GEMS regulations for 3 phase electric motors. For the end user this translates into reduced energy costs and a reduced impact on the environment.
Thanks to minimised internal pressure losses, the flow-optimised Sigma Profile screw compressor block and the inclusion of an IE4-rated drive motor, the latest generation HSD series rotary screw compressors additionally offer improved specific power, which further contributes to the all up efficiency of these compressors.
For the ultimate energy saving solution where compressed air demand fluctuates, the HSD series can be fitted with the Sigma Frequency Control drive (SFC).
The HSD rotary screw compressors from Kaeser feature an electronic Thermo Management system. This controls the oil temperature to ensure a safe and consistent differential from the dewpoint temperature. In addition, this feature creates energy savings by preventing unnecessarily high screw compressor block discharge temperatures.
The units are controlled and monitored independently of each other via two Sigma Control 2 controllers. Using the master-slave function, these controllers are able to precisely match performance of each compressor to suit current compressed air demand. This results in significant energy savings and optimum efficiency.
With sound pressure levels as low as 71 dB(A), the HSD series is available with total drive power 360 to 500 kW, working pressure 3.5 bar to 15 bar with combined free air deliveries from 42.5 to 85.2 m3/min (fixed speed drive) and 52 to 85.4 m3/min (SFC drive) at 50 Hz.
