suitable for refrigeration equipment and air conditioningsystems Its main features include high energy efficiency, energy consumption savings, low noise, and environmentally friendly refrigerant usage.
Scope of application: low-temperature condensing units such as freezing, refrigeration, and quick freezing, as well as ultra-low temperature environments
Product Overview The Copeland ZPD series represents industrial-grade, high-performance semi-hermetic reciprocating (piston) refrigeration compressors, specifically engineered for demanding commercial and industrial refrigeration systems. Renowned as an industry benchmark for their unmatched durability, exceptional serviceability, and broad application range, the ZPD137, ZPD154, and ZPD182 are three closely aligned capacity models within this series. Together, they provide a comprehensive solution covering medium to large-scale refrigeration needs, and are widely used in critical applications ranging from large supermarket cold chains to industrial cold storage facilities. Core Features and Advantages
Robust Semi-Hermetic Construction
Heavy-Duty Design: Utilizes high-strength cast iron crankcases and large bearings, capable of withstanding extreme operating conditions (e.g., liquid slugging, high discharge pressures), delivering exceptional reliability.
Field-Replaceable Components: This is a core advantage. The removable cylinder head allows for on-site inspection, maintenance, or replacement of key internal components (e.g., valve plates, piston rings, bearings, motors), significantly extending service life and reducing total cost of ownership.
High Efficiency and Reliability
Optimized Valve Design: Ensures high volumetric and energy efficiency, even under high compression ratios.
High-Performance Motor: Features motors with high insulation classes and built-in overload protection, ensuring stability during prolonged continuous operation.
Strong System Adaptability
Excellent Liquid Tolerance: The piston design is generally less sensitive to minor liquid refrigerant return (floodback) compared to scroll compressors, offering greater resilience and being somewhat more forgiving regarding system control precision.
Wide Operating Range: Capable of efficient operation across a broad spectrum of conditions, from medium-temperature (approximately -10°C evaporation) to low-temperature (evaporation temperatures down to -40°C or lower).
Proven Platform and Technical Support
As a classic and mature series, the ZPD benefits from well-established technology, readily available spare parts, and extensive维修资源, earning the trust of refrigeration engineers worldwide.
Model Specification Differentiation These three models form a clear capacity ladder, with the primary difference being their displacement (refrigeration capacity).

Important Technical Notes
Professional Selection and Installation: ZPD series compressors are complex industrial devices. Their selection must be based on precise system design calculations (evaporating temperature, condensing temperature, refrigerant, cooling capacity requirements, etc.). Installation and commissioning must be performed by qualified refrigeration engineers.
System Matching is Critical: Must be correctly matched with appropriately sized condensers, evaporators, expansion devices, and control systems to achieve optimal performance and reliability.
Consult Official Documentation: For the most accurate and complete technical parameters (performance curves, dimensional drawings, electrical data), always refer to the "Copeland ZPD Series Product Technical Manual"or contact official technical support.
Summary The Copeland ZPD137, ZPD154, and ZPD182 are workhorse models in the field of commercial refrigeration, representing the reliability and durability of semi-hermetic piston technology. They provide users with a scalable solution from medium to large capacity that is field-serviceable. Compared to hermetic scroll compressors, their core value lies in their extremely long service life and outstanding maintainability, making them particularly suitable for industrial and large commercial applications where long-term operational reliability and minimizing total cost of ownership are top priorities.
