Bitzer Semi-hermetic frequency-controlled
Semi-hermetic frequency-controlled
With the built-in preprogrammed frequency inverter of the VARISPEED series, the speed can be infinitely adjusted, which increases efficiency and lowers energy costs. The built-in suction gas cooling of the frequency inverter increases operating reliability and reduces maintenance to visual inspections only.
For Standard Refrigerants
ECOLINE VARISPEED
With their groundbreaking properties, the BITZER ECOLINE compressors are complemented by the new series with integrated frequency inverters (FI), allowing for seamless capacity control. Seamless capacity control minimizes suction pressure fluctuations and cycling rates, thus reducing energy costs. In particular, single-compressor applications can be completed with a considerably higher system efficiency.

OCTAGON 2-STAGE
Innovative lightweight compressors for transport cooling, heat pumps and special applications
For CO2
OCTAGON VARISPEED TRANSCRITICAL
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.
