Shared Product Features
Powerful Low-Temperature Performance & High Capacity:
Engineered for low evaporation temperatures, making them ideal for large cold storage rooms, blast freezers, and large-scale industrial ice makers.
Inherited Scroll Technology Advantages:
High Energy Efficiency:Significantly higher Coefficient of Performance (COP) compared to reciprocating compressors, leading to lower operating costs.
High Reliability:Fewer moving parts, high tolerance to liquid slugging, and good oil return characteristics result in low failure rates and minimal maintenance.
Smooth and Quiet Operation:The orbital motion of the scrolls ensures much lower vibration and noise levels than reciprocating compressors.
Robust Industrial-Grade Design:
Built with heavy-duty components to withstand harsh conditions and continuous, long-term operation, meeting the rigorous requirements of industrial applications.
Broad Operating Range:
Capable of stable and efficient operation across a wide range of condensing and evaporating temperatures.
Primary Applications
These models serve as the core power source for large commercial and industrial refrigeration systems. Typical applications include:
Freezing and Refrigeration:
Large prefabricated cold rooms (typically 50+ cubic meters)
Logistics and cold chain storage centers
Seafood and meat freezing storage
Low-temperature warehouses for pharmaceuticals and chemicals
Industrial Ice Making:
Large cube ice makers, flake ice machines, tube ice machines
Industrial Process Cooling:
Cooling for chemical processes, low-temperature reactor cooling
Selection and Usage Notes
Power Gradation:The ZB29KQ, ZB38KQ, and ZB45KQ form a clear power gradation, allowing for precise selection based on cooling capacity requirements.
Voltage Confirmation:These large-capacity models are designed for three-phase power (380V). This must be confirmed during selection and electrical planning.
System Matching:Professional engineering is required to correctly match the compressor with appropriately sized condensers, evaporators, expansion valves, and other components to ensure optimal system performance and longevity.
Professional Installation:Due to their weight and power, installation requires a solid foundation and professional piping techniques, strictly following operational procedures.
Summary: The ZB29KQ, ZB38KQ, and ZB45KQ are the high-capacity workhorses of Copeland's ZB series for large-scale low-temperature applications. Sharing the core benefits of scroll technology—efficiency, reliability, and quiet operation—they are a top-tier choice for building robust, large-capacity refrigeration systems.
