What is the difference between CRII cylinder unloading technology and an inverter, and when should CRII be used instead?

CRII Cylinder Unloading Technology is not a direct replacement for an inverter in all cases. Rather, it serves as a strategic alternative depending on your specific system goals.

Choose CRII when you require fast, robust and cost‑effective capacity control without the complexity of a VSD. Choose an inverter when part‑load efficiency and a smooth turndown are the primary objectives.

CRII should be used if very low partload is needed or if a very high control factor is requested (a higher control factor indicates better part-load performance and greater flexibility in adapting to varying load demands).
