Common Cooling Compressor Spare Parts and Compatible Model List

Cooling compressors are essential in refrigeration and HVAC systems across many industries, providing consistent cooling performance. To keep these compressors running smoothly, regular maintenance and timely replacement of worn components are necessary. Understanding the most commonly used spare parts and compatible models can help improve maintenance efficiency and ensure optimal compressor operation. Here’s a look at frequently replaced cooling compressor parts and the models they are typically compatible with.

1. Oil Level Limiter

The oil level limiter is essential for maintaining the correct oil levels within the compressor, which prevents issues related to both under- and over-lubrication. Proper oil levels reduce friction, prevent overheating, and support the compressor’s longevity and performance.

Compatible Models:

  • Hanbell: RC2-100B, RC2-140B, RC2-200B, RC2-370B
  • Bitzer: CSH and CSW series
  • Dorin: K and H series compressors
  • Carrier: 06D and 06E models

2. Oil Filter

Oil filters remove contaminants from the compressor’s oil, ensuring clean lubrication and reducing wear on internal components. Regular replacement of oil filters prevents blockages, lowers the risk of overheating, and supports smooth compressor operation.

Compatible Models:

  • Bitzer: Semi-hermetic and screw compressors in the CSH and CSW series
  • Carrier: Models 5H, 5F, 06D, and 06E
  • Hanbell: RC and RA series
  • Dorin: K and H series

3. Pistons and Piston Rings

Pistons and piston rings are crucial for creating and maintaining pressure within the compressor, supporting efficient compression and cooling performance. These components should be replaced when signs of wear appear to ensure consistent pressure and reduce strain on the compressor.

Compatible Models:

  • Bitzer: Open and semi-hermetic compressors in models CSH and CSW
  • Carrier: 5F, 5H, and 06E models
  • Hanbell: RC2 series, especially RC2-310 and RC2-370B
  • Dorin: K and H series compressors

4. Shaft Seal

The shaft seal prevents refrigerant and oil leakage around the compressor’s rotating shaft, helping maintain pressure, energy efficiency, and overall performance. Regular replacement of worn shaft seals reduces leakage risks and extends compressor life.

Compatible Models:

  • Bitzer: Semi-hermetic compressors in the CSH and CSW series
  • Carrier: 5F, 5H, 06D, and 06E models
  • Hanbell: RC series, including RC2-200B and RC2-470B
  • Dorin: Models in the K and H series

5. Gaskets and O-Rings

Gaskets and O-rings provide airtight seals within the compressor, helping to prevent refrigerant leaks and maintain proper pressure. Although small, these components play an essential role in energy efficiency and system integrity.

Compatible Models:

  • Bitzer: CSH and CSW series
  • Carrier: 06D, 06E, 5F, and 5H series
  • Hanbell: RC and RA series compressors
  • Dorin: K and H series

6. Suction and Discharge Valves

Suction and discharge valves control the flow of refrigerant into and out of the compressor, maintaining efficient operation and energy use. These valves must be replaced periodically to ensure optimal refrigerant flow and prevent inefficiency.

Compatible Models:

  • Bitzer: CSH and CSW series
  • Carrier: 06D, 06E, 5F, and 5H series
  • Hanbell: RC and RA series
  • Dorin: K and H series
