Oil-free compressor design is easy to
extend
Boge has developed a fundamentally new type of compressor - a modular oil-free system that is easy to extend and quick to service for the lower capacity range.
Boge has developed a fundamentally new type of compressor - a modular oil-free system that is easy to extend and quick to service for the lower capacity range - the OL Progressor Ideal for applications where there is no possibility of checking or changing oil or treating oily condensate in the preparation of compressed air, as well as applications demanding high air quality
These machines are rated for continuous operation and highly intermittent industrial applications These advantages have been achieved thanks to a radical new and unique design based on the sliding cam principle.
Two cylinders sit horizontally opposed to each other and the compressed air is created by way of a piston in the form of a shuttle driven by a single crank pin.
In addition there is a special cooling system combined with a stable-pressure radial fan which cools the air intake and directs it into the system for a continuous low temperature inside the cabinet for extended component life.
An air intake regulator is fitted as standard which means the compressor requires only 15% power when running off load, half that of an oil injected screw compressor.
The OL has been designed for saving space and on this basis, a single system emerged that could be rapidly extended to form a compressor station in as small a space as possible by adding other single systems to a common base-frame.
Thus a system consisting of three individual compressor modules takes up 30% less working space than one single compressor.
Furthermore, each module has the same advantages as a single compressor.
Every compressor is self-sufficient but can nonetheless be integrated in a common control system.
Therefore, with a three-module-system, one of the compressors can be serviced while the other two continue to compress air.
An additional compressor module is all that is required in order to turn a single compressor into a duplex system.
Screwing the modules together is very simple.
The only additional work is to connect the installation to the compressed air network and the mains.
The modular construction of the OL series not only takes up less space, but also offers all the advantages of a single compressor.
Each compressor is self-sufficient, can be serviced separately without affecting the other compressors and can be set on stand-by, which means that the compressor only switches on when required.
In addition, compressor operation can be regulated via a common control system; the advantage being that if, as practical experience shows, compressed air demand fluctuates during the day.
It is considerably more economical to run several individual systems or modular compressor systems than one single compressor.
Thus, with fluctuating demand, just one compressor runs during the night; during production time, two, three or more compressors run, depending on demand.
For optimum reaction to compressed air demand, we have developed a range of sizes.
With between 4 and 22.5kW, the OL series supplies air pressure deliveries of from 400 litres up to 2.8 cubic metres per minute.
Industrial models for 24-hour operation at full 100% are mainly intended for users who need between 8 to 20 bar of completely oil-free compressed air.
Apart from cost, ecological considerations can also a deciding factor for change, since oil-free machines do not produce waste in the form of oil or oil filters.
Instead of complicated and expensive filter technology, installing a simple refrigeration dryer will ensure high quality compressed air.
Service intervals of 8000 operating hours result in a further saving for the user.
With a three-shift system, this equals roughly one year of 24-hour running.
