The latest generation of the compact and dependable Aircenter all-in-one compressed air systems from Kaeser are not only more efficient than ever before, but they also now include a future-proof compressed air refrigerant dryer.

The user-friendly Aircenter is a complete turnkey system which incorporates a Kaeser rotary screw compressor, an energy efficient refrigeration dryer and an air receiver – all in one space-saving compact package. The space-saving design has long since made the Aircenter the ideal solution where space is at a premium, such as in auto body garages and workshops.

For 5.5kW to 9kW requirements, the Aircenter incorporates the Kaeser SM series rotary screw compressor. For maximum efficiency, the SM 10 and SM 16 compressor models both have premium efficiency IE3 motors, and the SM 13 compressor model is now equipped as standard with a super-premium efficiency IE4 motor. These motors comply with and exceed prevailing Australian GEMS regulations for three-phase electric motors. IE4 motors are the technology of tomorrow, with current regulation introduced in January 2015 only requiring the use of IE3 Class motors. For the end user this translates into the best possible compressor performance, reduced energy costs and significantly enhanced compressed air production efficiency, all available today.

For even greater intake volume and efficiency, the latest generation of SM series rotary screw compressors are also equipped with the SIGMA 06 screw compressor block, featuring even further refined Sigma Profile rotors. Together with the IE4 motor for example, Kaeser has been able to reduce the energy requirement of these compressors by up to 13%.

From the end of 2019, all refrigerant dryers from Kaeser Compressors have been using the new R-513A refrigerant. This includes the refrigeration dryers that can be found in the Aircenter models. R-513A refrigerant offers the most future-proof operating solution for refrigeration dryers. Utilising this climate-friendly refrigerant will assist compressed air users in future-proofing their system as Australia transitions to low-GWP (global warming potential) refrigerants as part of the Australian hydrofluorocarbon (HFC) phase-down.

All Kaeser refrigeration dryers are designed to provide maximum efficiency and energy cost savings. Thanks to the new refrigerant, they are also future-proof for their entire service life when it comes to applicable refrigerant legislation. With sound levels as low as 62 dB(A) the Aircenter is also suitable at point of use. The SM series Aircenter compressed air systems are available with drive powers of 5.5mkW to 9 kW, and produce flow rates from 0.59 to 1.62 cubic metres per minute, designed for pressures up to 15 bar.
