Understanding the difference between Sequencers and Master Controllers is important. Industrial businesses have to rely on John Henry Foster, St. Louis’ Compressed Air ROI Group, to help them understand these differences, and how they impact their business.
Sequencers
Sequencers are control systems designed to manage multiple air compressors within a system, optimizing their operation by sequencing their start and stop cycles based on demand. By automatically bringing compressors online or offline in the most efficient order, sequencers help balance load, reduce energy consumption, and minimize wear on individual units.
- Rotate compressed based on time
- Bring more on due to low pressure
- Load only
- Normally not fully controllable
Master Controllers
Master controllers provide centralized, intelligent control over an entire compressed air system, coordinating compressors, dryers, and ancillary equipment. These advanced systems monitor real-time performance data, pressure levels, and demand fluctuations to optimize overall system efficiency. Master controllers can also offer diagnostics, remote monitoring, and programmable settings, delivering enhanced reliability, energy savings, and streamlined operation for complex or large-scale compressed air installations.
