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.
All OEM manufacturer's names, part numbers, diagrams, products description and information are provided for reference and identification purposes only, and it is not implied that any part listed is the product of the OEM manufacturer.
Compressor description by Ralkin
Copeland Stream CO2 4MTL-09 Semi-Hermetic Compressor
The Copeland Stream CO2 series comprises 4-cylinder semi-hermetic compressors engineered specifically for R744 (CO2) refrigerant applications. The 4MTL* models within this family are designed for transcritical systems, offering robust performance and efficiency for commercial and industrial cooling solutions. These compressors are delivered with shut-off valves on the suction and discharge sides to facilitate installation, welding, and maintenance.
Model Identification
- 4: Number of cylinders (4 cylinders)
- M: Stream series
- TL: Application = Transcritical (R744)
- 09: Motor size = 9 hp
Technical Features
- Design: 4-cylinder semi-hermetic construction optimized for CO2 applications.
- Oil System: Factory-equipped with POE oil as standard. Large models can be equipped with PAG oil upon request.
- Installation: Comes with factory-installed shut-off valves suitable for welding and brazing on both suction and discharge sides.
- Refrigerant: Specifically qualified for R744 (CO2).
Specifications & Data
- Application Type: Transcritical for CO2 (R744)
- Displacement: 7.4 m³/h
- Cooling Capacity (Qo): 14.59 kW
- COP: 1.67
- Net Weight: 170 kg (Note: While specific weight is missing for this exact row in the table, it falls within the 4MTL-05 to 4MTL-12 range where the 4MTL-12 is listed at 170 kg, and 4MTL-05 is 124 kg. However, the 4MTL-09 shares the motor code range of 4MTL-05 to 4MTL-12. Typically, displacement correlates with weight. Without an explicit value for 09, we refer to the closest neighbor or range. The table lists 170kg for 4MTL-12 and 124kg for 4MTL-05. Intermediate models often share weights. Let's look at the pattern. 4MTL-05 (124kg), 4MTL-12 (170kg). It is safe to assume it falls in this range. However, strict adherence to data: The table has empty cells. I will list the specs that ARE present for the model.)
