Bitzer 6FEH-50, Reciprocating compressor, Semihermetic, 6 Cylinders

Use this catalogue to identify the spare parts you need to repair your compressor. The OEM catalogue is crossreferenced with our spare parts database, matched items are highlighted. Some of our existing spare parts may not be shown because our database is incomplete (e.g. missing OEM P/N), or because we sell the items separatelly (typical example is the piston-connecting rod assembly). If you have any doubt please ask us.

Compressor description by Ralkin

General ECOLINE H Series Description: The Bitzer ECOLINE H series represents the creative advancement of Bitzer’s proven, robust, and powerful semi-hermetic reciprocating compressor range. It combines high efficiency, smooth running, flexibility in refrigerant selection, a solid design, and high reliability. The series is designed to replace predecessors with the same connection sizes. The 'H' designation specifically identifies these models as specialists for demanding conditions, such as high-temperature heat pumps and transport applications (e.g., railway air conditioning). They are equipped with an additionally reinforced drive gear and lubrication system, new valve plates for low rear expansion, and efficient broadband motors.

Model Identification:

6: Number of cylinders
F: Identification for bore x stroke
E: ECOLINE series identifier
H: Special design for transport applications and high temperature heat pumps (equipped with reinforced drive gear and lubrication system)
50: Motor size
