Product Description

Product Description for ZB26KQE

Product Name:Semi-Hermetic Piston Compressor

Product Series:K Series, High-Efficiency Model

Core Overview

The ZB26KQE is a high-performance, high-efficiency semi-hermetic piston refrigeration compressor manufactured by the German company . It belongs to Bitzer's classic "K" series and is the high-efficiency model within this series (indicated by the "E" suffix in the model number). This compressor is renowned for its outstanding reliability, wide range of applications, and excellent energy efficiency, making it particularly suitable for various medium- and low-temperature commercial refrigeration scenarios.

Note:The above parameters are typical values. Specific refrigeration capacity, power input, and current vary significantly with changes in evaporation temperature, condensation temperature, and selected refrigerant. Precise data must be obtained from Bitzer's official selection software or technical manuals.

Features and Characteristics

High Efficiency and Energy Saving:As an high-efficiency "E" series model, the ZB26KQE features optimized internal flow paths, a high-efficiency motor, and an improved valve plate assembly designed to deliver a higher Coefficient of Performance (COP), helping to reduce system operating costs.
Robust and Reliable:Inheriting the fine tradition of the K series, it uses a high-strength cast iron body and precision-manufactured crankshaft, connecting rods, and pistons, ensuring long service life and stable operation under demanding conditions.
Excellent Part-Load Performance:Maintains high operational efficiency even under part-load conditions, adapting to the varying demands of actual operation.
Comprehensive Built-in Protection:Motor windings are embedded with PTC thermistors, providing reliable motor overheating protection and effectively preventing motor burn-out due to overload or phase loss.
High Maintenance Convenience:

Removable Suction Filter Screen:Easy to clean, effectively preventing system contaminants from entering the cylinders and causing wear.
Sight Glass:Allows for visual inspection of the lubricating oil level and condition.
Standard Crankcase Heater:Prevents refrigerant from migrating into the oil during shutdown, reducing the risk of liquid slugging at startup.

Strong Application Flexibility:Suitable for a variety of common refrigerants (including environmentally friendly alternatives) and a wide range of evaporation temperatures, meeting the needs of different refrigeration systems.
Smooth Operation:Precision dynamic balancing ensures low vibration and noise levels during operation.

Primary Application Fields

The ZB26KQE is a highly versatile compressor commonly found in the following areas:

Commercial Refrigeration/Freezing Display Cases:Open refrigerated counters, deli counters, freezer cases, and ice cream display cabinets in supermarkets.
Small and Medium-Sized Cold Storage Rooms:Such as refrigerated (+2°C to +8°C) and frozen (-18°C to -25°C) storage for restaurants, hotels, and distribution centers.
Food Processing and Preservation:Small ice makers, beer cooling systems, dairy product preservation equipment.
Industrial Cooling:Some industrial process cooling equipment requiring high reliability.

Model Number Explanation

Z:Standard series code.
B:Design code.
26:Indicates the compressor's displacement class.
K:Stands for Bitzer's "K-series" of semi-hermetic piston compressors.
Q:Typically denotes the basic design or standard configuration.
E:Stands for "Energy Efficient," the high-efficiency version of the standard model.

Selection and Usage Considerations

Accurate Selection:The compressor must be selected precisely based on the system's actual design conditions (evaporation temperature, condensation temperature, ambient temperature) and the chosen refrigerant, using Bitzer's official selection tools to ensure operation within an efficient and safe range.
Refrigerant and Oil:Strictly use the refrigerants and compatible lubricant types/viscosities recommended in the technical manual.
Electrical Specifications:Ensure power supply parameters (voltage, frequency, phase) match the compressor nameplate and correctly install overload protectors and other electrical components.
Professional Installation and Service:Installation, piping brazing, vacuum evacuation, and refrigerant charging must be performed by trained professionals to ensure a clean, dry, and properly functioning system.

Summary

The ZB26KQE is a highly trusted high-efficiency semi-hermetic piston compressor in the small to medium commercial refrigeration sector. It offers an excellent balance of efficiency, reliability, and adaptability. For refrigeration and freezing projects requiring a robust compressor with low operating costs, the ZB26KQE is a highly competitive choice.
