ECOLINE Transcritical 4PTEU 6LK/7LK
BITZER’s CO₂ compressors have also been setting benchmarks in transcritical CO₂ applications for many years. The series was revised to increase its efficiency once again, and optimise the suction gas flow control and the valve plates. The ECOLINE TE compressors also boast tailored motors for a wide range of applications with the natural refrigerant CO₂.
