The Copeland ZR47K3 is a medium-to-large displacement, semi-hermetic reciprocating compressor from the "K3" series. Renowned for its robust construction, high reliability, and ease of maintenance, it is widely used in various medium and low-temperature commercial refrigeration systems. Core Features & Advantages - Semi-Hermetic Construction
- Ease of Maintenance: The motor compartment and crankcase are interconnected, allowing for internal inspection and valve plate assembly replacement on-site without welding.
- High Reliability: Less susceptible to issues from contaminants and moisture compared to fully hermetic compressors; eliminates the risk of shaft seal leaks associated with open-type compressors.
- Excellent Efficiency and Capacity Control
- Modular Cylinder Head Design: Facilitates the installation and replacement of unloader components.
- Step Capacity Modulation: Typically offers multiple steps of capacity reduction (e.g., 0%, 33%, 66%, 100%) via solenoid-controlled cylinder unloading. This precisely matches system load, reducing energy consumption.
- Robust Mechanical Construction
- Heavy-Duty Bearings and Crankshaft: Designed for long service life and high-load operation.
- Forced Lubrication System: Utilizes a durable oil pump to ensure adequate lubrication of critical moving parts under all operating conditions.
- High-Efficiency Valve Plate Design: Optimized suction and discharge passages and valve design minimize pressure drop and improve volumetric efficiency.
-
- Compatible with various refrigerants, including R404A, R507A, R22 (being phased out), and newer alternatives like R448A and R449A.
- Suitable for both medium-temperature cold storage and low-temperature freezing applications.
- Integrated Motor Protection
- The compressor typically includes built-in motor protection modules based on current and temperature, preventing motor burnout due to overload or insufficient cooling.
The Copeland ZR47K3 compressor is commonly found in: - Commercial refrigerators and display cases
-
- Food processing and storage cold rooms
- Marine refrigeration systems
