BOCK flexxCO₂NTROL Compressors – Intelligent Capacity Control
BOCK flexxCO₂NTROL Compressors provide advanced capacity control technology designed to adapt compressor output to the current refrigeration load. Developed for BOCK transcritical CO₂ compressors, flexxCO₂NTROL enables capacity regulation across a wide operating range from 100% down to 25%, depending on operating conditions.
By matching compressor capacity more closely to actual system demand, the technology can improve efficiency while reducing unnecessary compressor operation.
Flexible CO₂ Compressor Capacity Control
A major advantage of BOCK flexxCO₂NTROL Compressors is the ability to provide almost stepless capacity regulation. This enables refrigeration systems to respond efficiently to changing cooling requirements, particularly during periods of part-load operation.
Key benefits include:
- Almost stepless capacity regulation of transcritical BOCK CO₂ compressors
- Wide capacity range between 100% and 25%
- Higher average evaporating temperature
- Improved performance during part-load operation
- Increased overall system efficiency
- Reduced investment and operating costs
Reduced Compressor Wear and Longer Operating Life
Traditional start-and-stop compressor operation can increase wear on both the compressor and drive motor. The flexxCO₂NTROL system minimises the number of compressor starts and stops by adjusting capacity to meet changing refrigeration demand.
Reducing start-stop cycles helps lower the risk of wear and can contribute to longer compressor and motor operating life.
Flexible Integration with Refrigeration Systems
flexxCO₂NTROL can be integrated into existing system controllers where digital capacity regulation for reciprocating compressors is available. The technology is suitable for both digital and conventional capacity control applications, providing flexibility across different refrigeration system designs.
It also provides an attractive alternative to frequency inverter technology where appropriate.
For modern transcritical CO₂ refrigeration systems requiring flexible capacity modulation, BOCK flexxCO₂NTROL Compressors combine intelligent control with improved part-load performance, reduced compressor cycling and increased system efficiency.
