Whilst maintaining the exceptionally compact footprint of previous models, Kaeser Kompressoren’s redesigned SM series rotary screw compressors now provide enhanced system power and cooling with further reduced sound levels. Moreover, with free air deliveries of 0.8 and 1.2 m³/min at 8 bar respectively, the SM 9 (5.5 kW) and SM 12 (7.5 kW) each deliver even more compressed air than their predecessors – 11 and 15 bar pressure versions are also available. These models are also joined by a 9 kW version, the SM 15, which delivers 1.5 m³/min at 8 bar. In addition, ‘T’ version models feature an integrated refrigeration dryer to ensure reliable compressed air drying.
The SM 12 can also be equipped with Kaeser’s “SFC” variable speed control, allowing system performance to be precisely matched to suit fluctuating compressed air demand. Users can also opt for an “Aircenter” package: Available in all three SM model sizes, each “Aircenter” includes a refrigeration dryer, a compressor mounted on a 270-litre air receiver and is available with variable speed control. All modules are enclosed within a single housing, so that the whole system appears as one unit. Each compressor uses a flow optimised “Sigma Profile” fluid-cooled airend and a EU EFF1-rated motor to guarantee excellent specific power with high energy-efficiency. Highly effective sound insulation and low airend speeds ensure that these ultra-quiet machines operate with minimal sound pressure levels of only 64/65 dB(A). Furthermore, Kaeser’s advanced cooling system provides the motor and fluid/compressed air coolers with fresh cooling air drawn in from the ambient surroundings to achieve low compressed air discharge temperatures.
The internal “Sigma Control Basic” controller provides automatic system monitoring and adjusts compressor performance to meet air demand. Models are also optionally available equipped with the “Sigma Control”, which allows connection to compressed air management systems.
