BITZER 4CES-9Y-40S semi-hermetic refrigeration compressor

BITZER 4CES-9Y-40S ECOLINE refrigeration compressor

The BITZER 4CES-9Y-40S is a semi-hermetic reciprocating compressor from the ECOLINE range. Its four-cylinder design and displacement of 32.48 m³/h at 50 Hz make it suitable for appropriately selected commercial refrigeration installations.

Typical applications include cold rooms, refrigerated storage and refrigeration equipment. Compressor selection must take account of the refrigerant, evaporating and condensing temperatures, required cooling capacity and the manufacturer's operating limits.

The 40S motor version supports 220–240 V three-phase operation at 50 Hz with delta connection, or 380–420 V three-phase operation at 50 Hz with star connection. At 60 Hz, the specified supply is 440–480 V three-phase with star connection. Wiring must follow the compressor nameplate and BITZER instructions.

The supplied packaging label identifies BSE 32 oil, CM-RC-02 protection mode, preparation for 1 CR2 capacity control and preparation for optional oil pressure monitoring. Preparation does not indicate that the corresponding optional control or monitoring accessories are installed.

For replacement applications, verify the complete compressor designation, electrical supply, refrigerant suitability, mounting dimensions, pipe connections and control equipment before ordering. JAB Sales supplies refrigeration components to professional service companies and distributors.
