            • Digitalisation of your compressed air supply station

            • Digitalisation of your compressed air supply station

              The SIGMA SMART AIR service package makes the advanced service of tomorrow, available today. 
              In addition to enabling entry into the world of predictive maintenance, SIGMA SMART AIR also supports step-by-step digitalisation of your compressed air system – all within the scope of Industrie 4.0

              We provide and support your company’s entire compressed air supply 24/7, 365 days a year. The best part is that you pay only for what you actually use.

              How does SIGMA SMART AIR work?

              The SIGMA AIR MANAGER 4.0 lies at the heart of the service package. Serving as the central intelligence core within the compressed air station, it assumes control tasks and provides data-streaming to the KAESER PLANT CONTROL CENTER. Process data are encrypted and transferred in real-time via a radio modem. The advantage of this approach is that the customer network remains untouched and sensitive data are protected. 

              Compressed air data and energy management are permanently monitored and analysed in the KAESER PLANT CONTROL CENTER. This consequently makes predictive maintenance possible. Compressed air system downtime - and the associated impact on production - is therefore significantly reduced. This ensures maximum effectiveness and efficiency of the systems throughout their entire life-cycle.

              Think SMART

              • Service package  
                Whether hardware or software, we provide the necessary components to make your compressed air supply SMART.
              • Maximum supply reliability 
                The process data analysis of the compressed air station makes it possible to determine the perfect timing for maintenance tasks. This approach consequently reduces downtime and increases energy efficiency, which, in turn, saves time and money.
              • Minimal costs, maximum transparency 
                The service price is based on the actual volume of compressed air generated. So, similar to your electricity bill, costs are flexibly adjusted according to under- and over-consumption.
        • Rotary screw compressors

        • Keep up the pressure

          Rotary screw compressors supply production processes in industry, trade and workshop applications with a reliable supply of quality compressed air. They are the preferred choice for users requiring constant pressure over prolonged periods.
          To ensure that our rotary screw compressors operate as efficiently as possible, we developed our own special rotor profile. Our SIGMA profile rotors provide you with energy savings of up to 15 % compared with conventional rotor profile designs.
          Furthermore, our airends with SIGMA profile rotors boast an exceptionally long service life. This is in no small part due to the roller bearings we choose to use: they are precision adjusted and generously sized. Combine this with our in-house high-end manufacturing processes with lowest possible manufacturing tolerances and you have an exceptional product.
            • Rotary screw compressors with fluid cooling

            • No matter whether a complete compressed air station or a single compressor: our fluid-injected rotary screw compressors deliver exceptional efficiency throughout their entire service life.

              • With efficient IE3 motors
              • Intake capacity: 4.75 to 15.70 m³/min – 99 % final vacuum
            • Heat recovery

            • A rotary screw compressor converts 100 % of the drawn electrical energy into heat. Up to 96 % of this energy can be recovered.

              The fully-enclosed design of modern rotary screw compressors makes them especially suitable for heat recovery. This fact applies to both fluid-injected as well as to oil-free compressors.
              • Reduce your energy costs:
                Energy costs account for up to 80 percent of life-cycle costs. By using heat recovery, you can significantly lower these costs.
              • You also reduce your CO2 footprint:
                Heat recovery lowers the CO2 emissions of your organisation because you utilise energy more efficiently.
          • Reciprocating compressors

          • Ideal for fluctuating air demand

            Rotary screw compressors supply production processes in industry, trade and workshop applications with a reliable supply of quality compressed air. They are the preferred choice for users requiring constant pressure over prolonged periods.
            To ensure that our rotary screw compressors operate as efficiently as possible, we developed our own special rotor profile. Our SIGMA profile rotors provide you with energy savings of up to 15 % compared with conventional rotor profile designs.
            Furthermore, our airends with SIGMA profile rotors boast an exceptionally long service life.

                    • SIGMA AIR UTILITY operator model

                    • "It's right there" – Compressed air at a fixed price

                      With the SIGMA AIR UTILITY operator model, you will secure a reliable supply of compressed air tailored to your needs – practically at the push of a button: You simply give us a few square metres of floor space, and we'll take care of the rest. Instead of investing in a complete compressed air station, all you pay for is the compressed air you actually use.

                      Here's how Kaeser's SIGMA AIR UTILITY operator model works:
                      • We'll analyse your compressed air needs and draw up an individual concept – based on what is required.
                      • Next we will build, install and operate the compressed air system.
                      • Our Kaeser Teleservice, the logistics centre and our extensive global service network ensure that compressed air is available at all times.
                      With the SIGMA AIR UTILITY operator model, you pay a fixed basic price that covers an agreed quantity of compressed air. When larger amounts are needed, a fixed contractual price applies for the additional quantities used. All prices remain in effect for the entire duration of the contract, which means no price increases.
                          • SIGMA AIR UTILITY operator model

                          • No compressed air worries:
                            We offer everything from a single expert source: from the analysis of your compressed air needs to the machines and service. That lets you and your personnel concentrate fully on your core tasks.

                            From fixed costs to variable costs:
                            Investments in a compressed air system are no longer needed. Your employees will have time for other tasks. That means: You have more liquidity, are saved from tapping into your working capital and have greater flexibility in deploying your personnel.

                            A system scaled to your needs:
                            A competitive market brings ups and downs. Are you cutting back your output, or perhaps stepping it up? Are you relocating your operations? With SIGMA AIR UTILITY you can remain flexible. We will adjust your compressed air supply to your needs.

                        • A Kaeser compressor is a purchase for life – and a decision that we always want you to look back on with satisfaction. To make sure of that, we put all of our energy and passion into the development of our machines as well as excellent customer advice and service.

                          Energy efficiency is a top priority.
                          The purchase price and service costs account for just a fraction of the total lifetime cost of a compressor. The biggest item by far is the cost of energy.
                          We have been striving for more than 40 years to reduce your energy expenses from compressed air production – but not only that. We also never lose sight of the service and maintenance costs and the constant availability of the compressed air supply.
