Base load change over (BLCO)
Advantages
- Even workload for all compressors in terms of operating hours.
- Maintenance work can be done during operfrequencyation.
- All compressors are activated with the same switch on/off pressure.
- High potential for energy savings.
- High efficiency for fluctuating air demand.
- User-friendly configuration.
- Compressors from other manufacturers can be connected.
Functionality
Master compressor: Is always the same compressor; it controls, which compressors should be switched on and how many are currently being used.
Slave compressor: Works according to the master compressor‘s specifications and pressure band. One or more compressors are activated as to requirement.
Base load compressor: Is the compressor that switches on first (1).
Peak load compressors: Are getting activated by the master compressor if required (2, 3).
Change interval: After a preset time, the Compressors change their priority and another compressor becomes base load compressor.
BLCO installed in compressor
- The master unit must have a RENNERtronic Plus Touch.
- Up to eight slave compressors can be connected.
- All other compressors are connected via a Modbus RTU module.
- Compressor of other manufacturers require a connection module.
