Bitzer ecoline-plus-transcritical 4PTEU-6LK

ECOLINE+ transcritical - 4PTEU-6LK

Based on the optimised ECOLINE compressors for transcritical CO₂ applications, ECOLINE+ compressors are the optimal solution for use in systems with high energy efficiency requirements. The line-start permanent-magnet (LSPM) motor technology makes it possible to fully exploit the high motor efficiency and low heat input into the refrigerant.
