BOGE COMPRESSORS, a manufacturer of compressors and compressed-air systems, has extended its S-4 series to include additional power ranges, and the oil-lubricated screw compressor with the large housing is now available.
With their efficiency and quiet running, the S-4 series the new Boge compressor shares the characteristics of previous S-4 designs. The latest model – the 90-kW S 91-4 – is also the most efficient screw compressor in its class, able to produce free air delivery at low specific-power consumption when compared with its competitors. These efficiency benefits are achieved thanks to the new model’s novel construction concept: the generously sized components reduce internal pressure losses. On top of that, Boge’s own internally developed air end is capable of achieving high efficiencies.
The S-4 series is notable for the direct drive on the air end (i.e., the assembly of the rotors and their housing.) The air end is hermetically enclosed and offers considerable advantages when compared with standard belt-driven models which can suffer from high levels of wear in certain areas of application. “Generally, V-belts need to be replaced two or three times a year,” explained Frank Hilbrink, product manager at Boge. “This, of course, has a certain cost impact, and is quite a disadvantage when compared to our direct drive-based system.”
When combined with a frequency converter, the speed of the new Boge compressor can be varied, making it ideal for adapting to the exact compressed air requirements for the task.
Using vibration isolation for individual components and the flow of cooling air, Boge has been able to reduce noise considerably, meaning the compressor is ideal for use even in the most demanding of sensitive environments.
To make the best use of the energy supplied to the device, heat recovery can be added optionally. Then, this draws heat generated by the device operation to warm service water (or for other processes.)
For intelligent compressed-air management, the modular focus, control 2.0 control system and “airtelligence” provides three interlocking controls. In combination with “Boge connect, they both result in even greater efficiencies, as all of the compressors installed throughout the system are controlled and monitored optimally. Maintenance tasks can be planned to minimize downtimes.
Also, users are able to access the system remotely, allowing them to react directly at the first signs of any issues with the device. Thus, Boge connect ensures increased operating safety, reduced operating costs, and prepares for Industry 4.0 via its digital interconnectivity options.
