Components:
3x VSD – variable speed drive for air compressors
3x Air compressors
2x solid dehumidifiers
Components are purchased as one system and are synced/adapted to each other. For example, frequency converter is fitted to the load that electro motor of the air compressor requires. It is assumed that given certain adaptions, VSD would work with other motors and air compressors would work with other VSDs. It is preferred though to sell it as a complete asset since this is a system design and not component design.
1 compressor + VSD works well with only 1 dehumidifier package. However, then there is no redundancy, as well as only half amount of the air is produced.
See section 1 in the snag below taken from Operation manual C049-3085-M-KJ-0003 .
3 x50% compressors + VSD
2 x 100% dehumidifiers
Meaning 2 compressors and 1 dryer package should be operational to produce 100% of designed capacity (3700 m3/h dry air).
Keep in mind maintenance (hence 1 extra compressor) and that air drier requires «recycling»: every 6th hour air driers automatically are switched, so that one of them is “recycling”, where completely dry air is blown through to remove humidity the drier has absorbed, so that it is ready for a new 6 hour round.
The answer being: components can be used separately but for the system to function as designed for its operational purpose all components are needed.
