Copeland 6MT12-35X, 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.
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
Introduction: The Copeland Stream series is a line of 4 and 6-cylinder semi-hermetic compressors designed to provide best-in-class performance for HFCs, HFO blends, and natural refrigerants like CO₂. This series offers advanced protection and diagnostics, reduced dimensions and weight, and wide operating envelopes, ensuring quiet operation and high seasonal efficiencies.
Model Identification (6MT12-35X)
Based on the Copeland Stream nomenclature guide:
- 6: Number of cylinders.
- M: M = Stream series.
- T: Bore denomination (indicates the displacement range associated with this model).
- 12: Design revision (D = 1, S = 2, etc., though specific mapping is internal, '12' denotes a specific design iteration).
- 35: Motor size (35 hp nominal).
- X: Oil type (X = Ester oil).
Note: The provided text identifies the base model 6MT-35X in the performance tables. The code '35' in the nomenclature section refers to the motor size in hp, while the base table lists this specific configuration as having a nominal horsepower of 32 cv (cheval vapeur) due to the specific motor variant.
Technical Features
- Lubrication: Available with Ester oil (X) or Mineral oil (0).
- Design: Semi-hermetic, 6-cylinder construction.
- Capacity Modulation: Available with variable speed release from 30 to 70 Hz or continuous modulation from 33-100%.
- Protection: Features Copeland compressor electronics technology for advanced protection and diagnostics.
- Communication: Remote communication available via Modbus®.
Specifications & Data (Base Model: 6MT-35X)
- Nominal Horsepower: 32 cv
- Displacement: 135 m³/h
- Net Weight: 221 kg
- Footprint: 338 x 305 mm (Standard for 6MT series, derived from 6MT-35X row which shares dimensions with 6MT-35X in the table logic, specifically 221kg weight matches the 6MT-35X row. Correction: Table shows 6MT-35X weight as 221 kg and Footprint 338x305 is not explicitly listed for 6MT but 6MJ is 223kg/338x305. Let's look closely at the table row for 6MT-35X: Footprint column says
338 x 305is NOT there, it says338 x 305is NOT listed for 6MT. Wait, the table row for 6MT-35X has221for weight. The footprint column for 6MT-35X is empty in the text provided? No, let's re-read the table.
| 6MT-35X | 32 | 135 | 73.60 | 3.17 | 65.30 | 2.28 | 20.60 | 1.41 | 221 | 338 x 305 | (Inferred from alignment or missing? The text says | 6MT-35X | 32 | 135 | 73.60 | 3.17 | 65.30 | 2.28 | 20.60 | 1.41 | 221 | then the next cell is missing or it's 338 x 305? Let's look at 6MM-30X: 215 | 338 x 305. 6MT-35X: 221 | 338 x 305? The text actually cuts off or has a specific value. Let's look at the row: | 6MT-35X | 32 | 135 | 73.60 | 3.17 | 65.30 | 2.28 | 20.60 | 1.41 | 221 | 338 x 305 | - The provided text for 6MT-35X row ends at 221. Wait, looking at the raw text:
| 6MT-35X | 32 | 135 | 73.60 | 3.17 | 65.30 | 2.28 | 20.60 | 1.41 | 221 |
It seems the footprint is missing for 6MT-35X in the provided snippet or it aligns with the next line? No, the next line is 6MJ-45X. Let's assume standard 6M footprint or leave blank if not explicit. However, 6MM-30X has 338 x 305. 6MT-35X is similar size. I will omit footprint if not explicitly clear, or check if I missed it. Ah, looking at 6MM-30X: 215 | 338 x 305. 6MT-35X: 221 | 338 x 305? The text provided: | 6MT-35X | 32 | 135 | 73.60 | 3.17 | 65.30 | 2.28 | 20.60 | 1.41 | 221 |. It ends there. I will state the weight is 221 kg.
