Supply Optimisation
The starting point for any supply optimization is to benchmark the specific power of the compressors. In other words, determine how many standard cubic feet per minute are generated by 1 kW of electrical power to the compressor.

Tegnon will use this data to determine:

  1. Whether the compressors are operating within industry benchmarks. For example, a 7 bar system should operate at at least
    4.5 scfm / kW
  2. Whether there are relative performance differences between compressors. In other words, one compressor is performing substantially better or worse than the others
  3. Whether the compressor control system is operating effectively. In other words, are certain compressors set up to produce the constant base load compressed air and other compressor set up to pick up the variability

Once it has been established that a supply performance issue exists, the source of the issue can be identified. These issues typically include:

  • Inappropriate or inadequate compressor control system between multiple compressors
  • Inappropriate use of base load-type compressor for variable load requirements
  • Poor compressor performance due to lack of maintenance, incorrect blow off settings, air intake conditions or constrictions

The second focus area of supply optimization is on the performance of the dryers and filters. Four typical issues arise:

  1. Incorrect type of dryer for process (refrigeration vs. heatless desiccant vs. heat regenerative desiccant)
  2. Incorrect sizing of dryer for process requirements
  3. Poor maintenance of dryer resulting in pressure drops and reduction in compressed air quality
  4. Poor maintenance of filter elements resulting in pressure drops and reduction in compressed air quality
