CONTROLLING TODAY WITH tomorrow’s technology

The latest generation of compressed air management systems from HPC KAESER includes the capability to embrace the future technological benefits of Industry 4.0


he latest generation in compressed air management systems from HPC

KAESER is the recently introduced Sigma Air Manager 2 (SAM-2). Having evolved from its predecessor SAM-2 it is much more than a control and management system for installations with multiple compressors. Capable of complete air system management it has the ability to monitor and record information relating to all the components of a compressed air system. Incorporating important features including the capability to embrace the future technological benefits of Industry 4.0, SAM-2 provides a valuable tool to assist complete system maintenance and reliability. SAM-2 optimises the compressed air system pressure (a 1 bar reduction in pressure can equate to a 6% energy saving), automatically adjusting compressed air delivery to accommodate fluctuating air demand and optimising system efficiency through constant analysis of the relationship between control losses, switching losses and pressure flexibility. SAM-2 will enable customers to benefit from planned future upgrades and services such as predictive maintenance so it has the potential not only to boost operational reliability and efficiency but significantly reduce energy costs further. Industry 4.0 or the Internet of Things

advanced 3-D Control. This takes into account factors apart from switching losses (start/stop) that influence compressed air system energy efficiency. These include control losses (idling and frequency conversion) and pressure flexibility (average increase above required pressure). This innovative control strategy predictively calculates the optimum achievable configuration and adjusts the connected components accordingly, all based on the specific pressure required by the user. SAM-2 supports operation in 30

has the potential to be a far-reaching revolution in production and the new Sigma Air Manager 2 makes this level of integrated control possible.

EXPLOITING LARGER DATA VOLUMES For example, it offers the ability to make predictions far in advance, network components and exploit much larger data volumes than ever before while ensuring significant energy cost savings and delivering a reliable, consistent and efficient compressed air supply. In addition, the ability to ensure the best possible compressed air pressure quality tailored to specific needs is vital in many compressed air applications and this is largely made possible by SAM-2’s

Operating status, pressure history, free air delivery, power consumption, maintenance and error messages can be easily displayed and analysed in real-time and retrospectively

languages while the high quality, easy- to-use 12-inch colour touchscreen shows at a glance whether the station is operating in the ‘green zone’ from an energy management perspective. Operating status, pressure history, free air delivery, power consumption, maintenance and error messages can be easily displayed and analysed both in real-time and retrospectively. Using a PC and network connection this data can be accessed conveniently from anywhere. This not only provides users with peace of mind but lays the foundation for predictive maintenance and enables energy management in accordance with ISO 50001.


Since Hi-line Industries completely re-engineered its market-leading range of Hi-DRI compressed air membrane dryers the company reports that strong uptake has seen these technologically advanced units sold into a wide variety of applications. Clearly impressed with the ability of Hi-DRI

membrane dryers to deliver superior levels of reliability, performance and energy efficiency the systems are proving popular with end users seeking ways to make it easier and less expensive to supply pneumatic equipment and instrumentation with clean, dry compressed air including medical, dental, paint/bodyshop, analytical equipment, robotics and laser printing industries. Notable features differentiating Hi-DRI

compressed air membrane dryers include a patented arrangement of structurally packed, permeable hollow fibres that are spirally wound on a support

core. This has the advantageous effect of combining efficient air flow with high contact areas to maximise drying performance. Their compact design ensures the products are

ideal for in-line installations that guarantee the delivery of dehydrated compressed air to the point of use. Moreover, no electricity or energy supply is required, making these lightweight units ideal for remote, isolated or other challenging requirements. The membrane construction of the units does not

deplete oxygen from compressor which means it can be used as ‘breathing air’ dryer. Furthermore, there is no condensed H2O to deal with as this is removed as a gas. Membrane dryers contain no refrigerants, making them environmentally friendly.

The far-reaching benefits of the SAM- 2 are expanded even further when users take advantage of HPC KAESER’s Sigma Network. Based on Ethernet technology, the powerful, closed and secure network has been specially developed to support optimal monitoring and coordinated control of compressed air stations. SAM-2 offers additional powerful features which enable remote diagnostics and predictive maintenance. For example, maintenance and error messages can be immediately sent via email to a pre-set personal address and the remote diagnostics option allows for preventative maintenance and service based on actual use. Both elements increase compressed air availability and reliability and help keep lifecycle costs to an absolute minimum.
