Copeland ZB Scroll Compressor – Medium Temperature Refrigeration
Copeland™ ZB refrigeration scroll compressors are engineered for reliable and efficient medium-temperature commercial refrigeration. The ZB*KQ family covers a wide range from approximately 2 HP to 30 HP for cold rooms, supermarkets, food retail, process cooling and commercial refrigeration systems.
The Copeland ZB series is specifically optimized for medium-temperature refrigeration applications. Its scroll compression technology combines high efficiency, compact size, low sound and vibration, and robust liquid-handling capability for demanding refrigeration systems.
📋 ZB Series at a Glance
🔍 ZB Compressor Range
2 – 7 HP
Compact ZB refrigeration scroll compressors for smaller cold rooms and commercial refrigeration equipment.
8 – 15 HP
Medium-frame compressors for larger refrigeration systems, cold rooms and supermarket applications.
20 – 30 HP
Large refrigeration scroll compressors for higher-capacity commercial and industrial cooling systems.
✨ Key Features & Benefits
Scroll Technology
Continuous scroll compression provides smooth operation with substantially fewer moving parts than traditional reciprocating compressors.
Axial & Radial Compliance
Copeland scroll compliance technology improves reliability and helps the compressor tolerate liquid refrigerant and small debris.
High Efficiency
Optimized scroll geometry delivers high refrigeration efficiency across medium-temperature operating conditions.
Low Sound & Vibration
Smooth and continuous compression helps reduce refrigerant pulsation, operating sound and vibration.
Compact Design
High capacity from a relatively compact compressor body provides flexibility for refrigeration-system design.
Refrigeration Optimized
The ZB family is specifically developed for medium-temperature commercial refrigeration duty.
💡 Copeland Dual Compliance Scroll Technology
Copeland ZB scroll compressors use axial and radial compliance between the fixed and orbiting scrolls. This provides effective sealing during normal operation while allowing the scroll elements to separate when necessary, improving liquid and debris handling capability and contributing to long-term compressor reliability.

🌡️ Refrigerant & Lubricant Identification
The Copeland ZB platform has been produced in different refrigerant and lubricant configurations. Refrigerant compatibility therefore must be checked using the complete compressor model and BOM number rather than only the basic ZB capacity designation.
| Identification | Meaning |
|---|---|
| ZB | Medium-temperature refrigeration scroll family |
| 15 / 38 / 76 / 220 etc. | Base capacity designation at the Copeland medium-temperature rating condition |
| K | Capacity multiplier × 1,000 |
| Q | Compressor generation designation |
| Blank after Q | Mineral-oil configuration in the referenced catalogue |
| E after Q | POE-oil configuration in the referenced catalogue |
| TFD / TWD / etc. | Motor and electrical configuration |
| BOM Number | Determines connection and product configuration |
Do not assume every ZB model is suitable for the same refrigerant. R22, R404A and R134a applications exist within the ZB platform, but approval varies by compressor model and configuration.
Always verify the complete Copeland model, refrigerant and BOM before replacement.
🔧 Connection & BOM Options
Depending on model and BOM configuration, Copeland ZB compressors may be supplied with stub-tube or Rotalock connections. Oil sight glass and Schrader-valve arrangements also vary across compressor frames.
Two compressors with the same basic ZB model may have different motor codes, electrical supply, connection arrangements or BOM configurations.
For an exact replacement, provide a clear photo of the complete compressor nameplate.

🔍 How to Select the Correct Copeland ZB Compressor
Never select a replacement Copeland ZB compressor only by horsepower or basic model number.
Always confirm the complete model, BOM number, refrigerant, lubricant, voltage, phase, cooling capacity, operating temperatures and connection type before ordering.
