Cost-effective compressed air production, treatment and storage with minimal space requirement: The ‘Aircenter’ series from KAESER KOMPRESSOREN features the very latest technology to provide unrivalled user advantages and exceptional performance. KAESER’s ‘Aircenter’ packages operate quietly and efficiently to provide a reliable and cost-effective source of application-specific compressed air. With a footprint of only about one square metre, these compact units are the perfect choice for installation in environments where space is at a premium. At the heart of these versatile ‘Aircenter’ packages is a high performance SX, SM or SK series rotary screw compressor. Covering a free-air delivery range from 0.33 m³/min to 2.2 m³/min at 8 bar and equipped with drive motors from 2.2 kW to 15 kW, these units ensure exceptionally low noise levels between 60 and 65 dB(A). 11 and 15 bar versions are also available for applications that require larger volumes of compressed air. Furthermore, the 'Aircenter 12' and 'Aircenter '21' can be equipped with KAESER’s “SFC” variable speed control, which allows compressor performance to be precisely matched to suit fluctuating compressed air demand. An integrated refrigeration dryer ensures reliable compressed air drying and is thermally shielded to prevent exposure to heat from the compressor package. Air quality can also be exactly tailored to suit an application’s specific air needs with the use of optionally available filters. The compressed air is stored in either a 200-litre (Aircenter 3, 4, 6 and 8), a 270-litre (Aircenter 9, 12 and 15) or a 350-litre air receiver (Aircenter 21 and 24) installed beneath the compressor. All three modules – the compressor, dryer and air receiver – are enclosed within a single housing, so that the whole system appears as one unit. In keeping with the turnkey design, all ’Aircenter’ systems are ready for immediate operation once the unit has been connected to the mains supply and compressed air network.
Component accessibility is also made simple, as all 'Aircenter' models feature easy to remove housing panels. Combined with this exceptional ease of maintenance, each ’Aircenter’ model represents the very latest advances in air system performance and design: Every unit uses a flow optimised “SIGMA PROFILE” fluid-cooled airend and a EU-eff1-rated* motor to guarantee excellent specific power with high energy-efficiency. The motor and airend in SM and SK units are connected via a V-belt drive system equipped with an automatic tensioning device, whilst the SX uses a maintenance-free drive belt. Effective sound insulation and low airend speeds further help to keep sound emissions to a minimum. In addition, a high-efficiency cooling system provides the motor and fluid / compressed air coolers with fresh cooling air drawn in from the ambient surroundings to achieve exceptionally low compressed air discharge temperatures. The internal “SIGMA CONTROL” provides automatic system monitoring and precisely adjusts compressor performance to match actual compressed air demand. Moreover, it enables the compressed air supply system to be seamlessly integrated into a centralised control system. Alternatively, the 'SIGMA CONTROL BASIC' controller is available for stand-alone units. *: Motors awarded this rating meet the stringent energy-efficiency requirements of the EU "eff1" standard adopted by the Committee of European Manufacturers of Electrical Machines and Power Electronics. This self-imposed standard equates to the American "Energy Policy Act" (EPACT).
