COPELAND ZB Refrigeration Compressor ZB19KQ ZB21KQ ZB26KQ Factory direct sales
Share to:
Vortex refrigeration compressor, Its core characteristics Including high energy efficiency ratio, low noise, high reliability, and the use of dual flexible vortex design, it enhances the resistance to liquid impact and impurity tolerance. This series of compressors usually adopts a fully enclosed structure, with a voltage of 220V/380V, and supports refrigerants including R22, R404A, R507, etc. The power range covers 2 to 3 horsepower (approximately 2.15 kW), mainly used in medium and low temperature refrigeration equipment such as cold storage and chillers.
These models are medium-to-large capacity scroll compressors from the Copeland "ZB" series, designed for heavy-duty commercial and industrial low-temperature applications.

Shared Product Features
Powerful Low-Temperature Performance:
Engineered for low evaporation temperatures, making them ideal for medium-sized cold storage rooms (-25°C to -30°C), blast freezers, and industrial ice makers.
Inherited Scroll Technology Advantages:
High Energy Efficiency:Significantly higher Coefficient of Performance (COP) compared to reciprocating compressors of similar power, 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 demanding 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, adapting to various climatic conditions and seasons.
Primary Applications
These models serve as the core power source for medium-sized commercial refrigeration systems. Typical applications include:
Freezing and Refrigeration:
Medium to large prefabricated cold rooms (10-50 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 ZB19KQ, ZB21KQ, and ZB26KQ form a clear power gradation, allowing for precise selection based on the cooling capacity requirements of the application.
Voltage Confirmation:These larger models are almost exclusively 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 refrigerant components to ensure optimal system performance and longevity.
Professional Installation:Due to their weight and power, installation requires a solid foundation and professional piping/welding techniques, strictly following operational procedures.
Summary: The ZB19KQ, ZB21KQ, and ZB26KQ are the "bigger brothers" to the ZB15KQE, offering greater power and capacity. They form the core of Copeland's product line for medium-duty commercial and industrial low-temperature applications. Sharing the benefits of scroll technology—efficiency, reliability, and quiet operation—they are a top-tier choice for building robust medium-sized refrigeration systems.
