| If a company expects fluctuating consumption of compressed air and is planning later extensions, it needs a compressor designed for intermittent operation. A piston compressor is the ideal choice. If the FAD of a compressor can cover the constant compressed air requirement then a screw compressor should be used.
Both compressor systems are available with full silencing. Both are supplied ready for use.
The choice of the right system should not depend on the purchase price, because the system pays for itself quickly if overhead operating costs are saved. Overhead operating costs are not only the energy costs to produce compressed air but also the costs of idling.
Piston compressors work in intermittent operation. They do not have an idle mode. Screw compressors must, because of their small cycle differential and relatively small compressed air receiver, automatically run in idle mode in order to avoid having too many motor cycles.
The ARS control unit aims for intermittent operation with minimum idling time. |
