Plants with several compressors often waste energy by running them independently. A sequencer coordinates the machines so only the needed capacity runs.
Why Sequencing Matters
- Multiple fixed machines can fight each other.
- Only the required capacity should run.
- Base load plus a VSD trim machine is efficient.
Control Strategies
- Lead and lag control with rotation.
- One VSD machine trims the variable load.
- Central controller optimises the whole system.
Benefits
- Lower part-load energy use.
- Even wear across machines.
- Reserve capacity available when needed.
What is a trim compressor?
A VSD machine that adjusts to match the varying part of the demand while fixed machines provide base load.
