Compressor description by Ralkin

The Carrier 06D series comprises semihermetic reciprocating compressors designed for robust performance in various commercial and industrial HVAC and refrigeration applications. Known for their durability and efficiency, these compressors offer flexible configuration options to meet specific system requirements.

Model Identification

• 06D: 06D Semihermetic Reciprocating Compressor
• R: Low Temp - No Unloaders (Refrigeration Duty)
• 7: Nominal Motor Size (10 HP for 6-cylinder configuration)
• 18: Displacement 18 CFM, 4 Cylinders, 2" Cylinder Bore (Note: Standard data for 18 CFM indicates 4 cylinders, but the digit '8' in position 7 of '718' usually implies the displacement digit. Let's re-parse based on standard 06D structure: 06D [Var] [Motor] [Disp/Cyl] [Key] [Valve] [Overload] [Elec].

Let's decode 06DR718 properly:

• 06D: Series
• R: Variation (Low Temp, No Unloaders, Refrigeration)
• 7: Digit 5 (Motor Size). Looking at the table for Digit 5: '7' corresponds to 5 HP for 4-Cyl or 6.5 HP for 6-Cyl. We need to check Digits 6-7 to determine cylinder count.
• 18: Digits 6 & 7. '18' corresponds to 18 CFM Displacement. The table shows 18 CFM has 4 Cylinders, 2" Bore, and Crankcase 6D46-249.
• Correction on Digit 5 lookup: Since Digits 6-7 are '18' (4 Cylinders), we look at the 'Motor (4-Cyl)' column for Digit 5 = '7'. The table says '7' -> 5 HP for 4-Cyl.
• Digit 8: The model string provided is 6D47 06DR718. The prompt example showed a 14-digit number. 06DR718 is only 7 characters after the prefix. Let's look at the requested model: 6D47 06DR718. This looks like a concatenation of two parts or a specific commercial format. Usually, 06D models are longer. However, based on the provided text 06DR718, we decode the visible suffix.

Let's assume the user input 6D47 06DR718 implies the base code is 06D and the specific config is R718.... Wait, 6D47 might be a separate part number or the user pasted the displacement code 6D46 (for 18CFM) or 6D75 (for 37CFM?).

Let's stick to the strict decoding of 06DR718 as provided in the main sequence, noting that 7 is the motor digit and 18 is the displacement digit.

• 06D: 06D Semihermetic Reciprocating Compressor
• R: Low Temp - No Unloaders, Refrigeration Duty
• 7: Motor Size: 5 HP (based on 4-cylinder configuration from displacement 18)
• 18: Displacement 18 CFM, 4 Cylinders, 2" Bore

(Note: The input 6D47 is ambiguous. If 47 refers to displacement 47 CFM, that is not in the table. If it refers to 6D series 4 cylinder 7 motor, it aligns. I will proceed with the 06DR718 segment decoding as the primary model identifier).

Technical Features

• Design: Semihermetic reciprocating design ensuring long service life and low maintenance.
• Lubrication: Patented oil return system maintains proper lubrication under varying load conditions.
• Capacity Control: Variable depending on specific valve unloading configuration (this model R indicates no unloaders, constant capacity).
• Durability: Heavy-duty construction with high-grade materials for reliable operation in harsh environments.
