Product Description for ZB58KQ and ZB58KQE Refrigeration Compressors This is a detailed product description of the ZB58KQand ZB58KQErefrigeration compressors. They belong to its mature and reliable "K" series and are widely used in various medium and low-temperature commercial refrigeration applications. Core Overview The ZB58KQ and ZB58KQE are high-performance, high-efficiency semi-hermetic piston compressors, known for their robust construction, stable operation, and ease of maintenance. They are primarily designed for refrigeration systems using medium and high-pressure refrigerants such as R404A, R507, and R22 (being phased out). The ZB58KQEis the energy-efficient version of the ZB58KQ. While their appearance and basic structure are very similar, the main difference lies in the motor efficiency and performance curve. The ZB58KQE typically offers a higher Coefficient of Performance (COP) under the same operating conditions. Product Images / Appearance (As I cannot provide images directly, please use the following keywords in a search engine or on the Bitzer official website)
Keywords:Bitzer ZB58KQ, Bitzer ZB58KQE
Appearance Characteristics:
Classic cylindrical semi-hermetic housing with the discharge port and terminal box on top.
Note:Specific refrigeration capacity, power input, and current vary significantly with changes in evaporation temperatureand condensation temperature. Precise data must be obtained from Bitzer's official selection software or technical manuals. Features and Characteristics
Robust and Reliable:Utilizes a high-strength cast iron body and precision-machined crankshaft and connecting rod mechanism, ensuring long service life and heavy-duty operation.
High Efficiency and Energy Saving (Especially ZB58KQE):Optimized valve plate design and high-efficiency motor ensure high energy performance across a wide operating range, reducing operating costs.
Good Part-Load Performance:Maintains good efficiency even when operating under partial load conditions.
Built-in Protection:The motor windings are embedded with Positive Temperature Coefficient (PTC) thermistors, providing motor overheating protection and preventing burn-out.
Convenient Maintenance:
Suction Filter Screen:Removable and cleanable, preventing contaminants from entering the cylinders.
Sight Glass:Allows for easy observation of oil level and color.
Crankcase Heater:Standard equipment, prevents refrigerant from dissolving into the oil during shutdown, reducing the risk of "liquid slugging" at startup.
Wide Range of Applications:Suitable for various refrigerants and different evaporation/condensation temperatures, offering flexible application.
Low Vibration and Noise:Precision dynamic balancing design ensures smooth operation and relatively low noise levels.
Primary Application Fields These compressors are the "workhorses" of the commercial refrigeration field, commonly found in:
Medium and Low-Temperature Cold Storage:Such as frozen storage (-25°C to -18°C) and chilled storage (0°C to +5°C) for food wholesale and logistics centers.
Commercial Display Cases:Freezer/cooled display cases, ice cream cabinets in supermarkets.
Industrial Refrigeration:Process cooling in certain food processing and chemical industries.
Ice Makers.
Model Number Explanation
ZB:Likely represents a specific series or design code.
58:Indicates the compressor's displacement class. A larger number generally means greater displacement.
K:Stands for Bitzer's "K-series" of semi-hermetic piston compressors.
Q:Typically denotes the basic or standard type.
E:Stands for "Energy Efficient" and is the high-efficiency upgrade of the Q-type.
Selection Considerations
Operating Condition Matching:It is essential to select the appropriate compressor model based on the actual application's evaporation temperature, condensation temperature, and ambient temperature to ensure it operates within its high-efficiency zone.
Refrigerant Compatibility:Confirm the refrigerant type used in the system design and select the compatible refrigeration oil.
Power Supply Requirements:Confirm electrical parameters such as voltage (e.g., 380V/3Ph/50Hz) and frequency.
Professional Installation:The compressor's installation, piping connection, vacuum evacuation, and refrigerant charging must be performed by qualified technical personnel.
Summary: The ZB58KQ and ZB58KQE are two very mature and classic medium-to-large semi-hermetic piston compressors from COPELAND, renowned for their high reliability and adaptability. When selecting, if the budget allows and long-term operating costs are a priority, the ZB58KQEis the superior choice.
