Product Description: Copeland ZR/VR Series Compressors (Model: ZR34K3-PFJ)1. Series Overview The ZR/VR series are historically significant and well-proven semi-hermetic reciprocating compressors under the Copeland brand. Renowned for their exceptional reliability, durability, and wide applicability, this series is extensively used in various commercial and industrial refrigeration systems.
ZR modelstypically refer to compressors designed for medium- and low-temperature applications.
VR modelsgenerally indicate variants with larger displacement, suitable for a broader capacity range.
The ZR34K3-PFJis a highly classic and prevalent model within this series, specifically engineered for medium- and low-temperature operating conditions.
2. Core Technologies and Features
Robust Reciprocating Technology:
Mature and Reliable:Utilizes a piston design validated over decades, featuring mature technology and widespread maintenance expertise.
Powerful Compression Capability:Ideal for medium- and low-temperature applications, capable of stable operation under high pressure ratios.
Heavy-Duty Design:Critical components such as the crankshaft, connecting rods, and valve assemblies employ a heavy-duty design, ensuring long service life.
Advanced Valve Technology:Incorporates efficient valve design that optimizes gas flow, reduces energy loss, and enhances both efficiency and reliability.
Comprehensive Motor Protection:
Features a built-in motor protection module that continuously monitors motor winding temperature and current, providing safeguards against overload, phase loss, and phase reversal to prevent motor burnout.
The "-PFJ" suffix in the model number typically denotes a specific terminal box and protector configuration.
Broad Compatibility:
Suitable for common HFC refrigerants used in medium/low-temperature applications, such as R404A and R507. Earlier models are also compatible with R22.
Designed to adapt to complex operational demands, offering a wide operating range.
Ease of Maintenance:As a semi-hermetic compressor, it allows for on-site maintenance and repair, which is an advantage not offered by fully hermetic compressors.
3. Typical Application Areas Medium-displacement compressors like the ZR34K3-PFJ are widely used in: Commercial Refrigeration:Medium to large freezer rooms in supermarkets, frozen display cases, and low-temperature cold storage rooms in back-of-house areas. Food Processing:Medium-sized cold storage warehouses, cooling lines in slaughterhouses, and food processing plants. Industrial Refrigeration:Process cooling in chemical industries and large ice makers
