OCTAGON VARISPEED transcritical

On the notepad Given the output characteristics of CO₂ systems, an efficient and seamless capacity control is particularly important. Therefore, for years BITZER has provided compressors with built-in frequency inverters (FI) for trans-critical CO₂ applications. This range of models has now grown once more with the new 4PTC-7.F3K compressor. Seamless capacity control minimizes suction pressure fluctuations and cycling rates, thus reducing energy costs.
