Base Load Change Over
Advantages of BLCO
- Even workload for all compressors in terms of operating hours
- Maintenance work can be done during operation
- 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 and activated
Functionality
Master compressor: is always the same compressor; Master controls, which and how many compressors are activated.
Base Load compressor: is the compressor that is activated first (K1)
Switching interval: the base load compressor alternates after a defined number of load hours. The switching interval can be adjusted.
Base Load Change Over (installed in compressor)
1. Using RENNERtronic control:
The master compressor must be equipped with RENNERtronic. All other compressors (up to 4) are
controlled by the MK200 module.
2. Using RENNERtronic Plus control:
Up to 4 other compressors (slaves) can be connected. The compressors are connected via an RS485-interface. Compressors from other manufacturers are connected via a slave module.
Other features:
The base load compressor can be activated by a timer. The base load compressor can be one particular compressor and all other compressors take turns.
Application examples:
A new energy efficient compressor runs permanently and covers all demand for air. A second, old compressor will be activated once a week for 2 hours to prevent standstill damage. A high-performance compressor with variable speed control has priority during day time. At night priority is given to a RS-B which is sufficient for the lower air demand that time. The base load compressor can be determined, all other peak load compressors alternate.
