Factory Price Commercial Heat Pump Compressor ZW Series-ZW108KSE-TFP-522 ZW108KS-TFP-522 High Refrigeration Heat Exchange Parts
Share to:
A scroll compressor suitable for air conditioning heating, cooling, and air source heat pump systems, with a power of 9 horsepower (approximately 6.3 kW) The compressor uses R407C traditional refrigerant, with a focus on high efficiency, low noise, and high reliability in its design, and adopts waveform winding technology to optimize performance
Applications:Large commercial refrigeration systems, such as low-temperature cold storage, freezer display cases, food processing equipment, and industrial freezing.
Refrigerant:Typically designed for medium-low temperature refrigerants like R404A and R507.
Core Technology:Scroll compression technology, known for high energy efficiency, low noise, smooth operation, and reliability.
Model Number Decoding
These two model numbers are very similar. Breaking them down explains their meaning:
ZW:Designates the basic scroll compressor series.
108:Indicates the compressor's displacement and capacity class. This is a high-capacitymodel, typically corresponding to approximately 12-15 Horsepower (HP).
K:Represents a specific product generation or design platform.
S:Stands for Standard Efficiency.
E(Present only in the first model): This is the key differencebetween the two models. The Etypically stands for "Enhanced Protection,"meaning the compressor includes an integrated protection module (usually with motor temperature sensors, pressure sensors, etc.), providing comprehensive motor and system protection.
ZW108KS:Standard protection.
ZW108KSE:Enhanced protection.
TFP:Refers to the compressor's physical dimensions, mounting base, and connection types. This is a manufacturer's internal code.
522:Typically an electrical specification code denoting ratings like voltage and frequency (e.g., likely 380V/3-Phase/50Hz - must be verified against official technical documentation).
Summary of Core Differences
Feature
ZW108KSE-TFP-522
ZW108KS-TFP-522
Model Suffix
ZW108K S
ZW108K S
Protection System
Enhanced Protection.Includes an advanced internal module for superior protection against motor overheating, overload, and other faults.
Standard Protection.Features basic internal protection functions.
Reliability
Higher.Suited for harsher operating conditions or applications demanding maximum reliability.
Standard reliability, suitable for standard operating conditions.
Cost
Typically higher.
Usually relatively lower.
Commonalities:
The core mechanical structure, displacement (108), and cooling capacity are identical.
The physical dimensions, mounting base (TFP), and electrical connections (522) are exactly the same.
Application Advice
ZW108KSE-TFP-522 (With Enhanced Protection):
This is the more recommended and commonly used configuration.
Particularly suited for harsh operating conditions, frequent cycling, or environments with unstable voltage.
Provides greater safety and stability for the entire refrigeration system, minimizing downtime risk due to compressor failure.
ZW108KS-TFP-522 (With Standard Protection):
Suitable for projects with stable operating conditions, well-designed systems, and budget constraints.
May be selected if adequate external protection components (like pressure controllers, overload protectors) are already in place within the system.
Important Notes
Professional Component:These are core components for large commercial/industrial systems. Their selection, installation, and commissioning must be performed by qualified refrigeration engineers.
Consult Official Documentation:The most accurate source of information is the "Copeland ZW Series Product Selection Guide"or "Technical Handbook."You can search the Emerson website using the full model number.
System Matching:When selecting a compressor, it is crucial to ensure it is fully compatible with other system components like condensers, evaporators, and expansion devices.
In summary, the ZW108KSE-TFP-522and ZW108KS-TFP-522are two versions of the same high-capacity scroll compressor, differing primarily in their level of internal protection. In the vast majority of cases, choosing the model with the E(Enhanced Protection) is a more prudent and advisable decision.
