BOGE AMERICA INC. claims its S-4 air compressor machine sets a technological milestone in the screw compressor sector. Following a redesign, the system is not only extremely efficient but also “whisper quiet” at 69 dB(A) — making it suitable for installation in places where excessive noise is a concern. The enclosed direct drive ensures low-maintenance continuous operation, even with high dust volumes. The focus control 2.0 (process control) system supports interconnected operation with up to four units, without resorting to additional, higher-level control.
For customers demanding compressed air systems with minimal power consumption in the range from 110 to 160 kW, Otto Boge GmbH & Co. has revised the design principle for oil-lubricated screw compressors: the gains in efficiency are due to the “effilence IntegrateDrive,” Boge's first airend to feature integrated gears. The large-scale design of the compressor provides high delivery rates with low power consumption, so energy consumption is reduced by as much as 8%.
The integrated gears are hermetically enclosed. The drive has optimal protection from high levels of dust in the ambient air, and the result is a low-maintenance, extremely long service life of over 35,000 operating hours.
A machine unit isolated from vibrations is the key to low noise. At 69 dB(A) the new generation is 7 dB(A) quieter than the previous model. To achieve this, Boge isolated the oil separator from the base frame and the soundhood to prevent the transmission of any vibrations. To accomplish isolation, Boge came up with a first: designing a vertical oil separator with a new pre-separation system. Other benefits are a low residual-oil content in the compressed air, minimal pressure losses, and a long service life for the separating element. As the machine is so quiet, it can also be used in environments that are sensitive to noise, e.g. next to a workstation. No additional sound insulation is required for the structure.
The focus control 2.0 control system is designed to anticipate operating states and automatically adjusts to the temperatures and pressure levels that occur. Entirely in line with Industry 4.0, the new Boge system makes it possible to simultaneously monitor the operating states and maintenance intervals of up to four compressors. This not only extends service life significantly, but it allows the user to take full advantage of the potential offered by the system. Thus, S-4 screw compressors are suitable for three-shift operation. When maintenance is required, there is easy access to components via the removable service doors on two sides of the screw compressor.
