Product Description

Product Description for ZB19KQE-TFD-558 Refrigeration Compressor

Product Name:Semi-Hermetic Piston Compressor with Specific Accessories

Product Series:K Series, High-Efficiency Model

Core Overview

The ZB19KQE-TFD-558 is a fully-featured version of the ZB19KQE high-efficiency piston compressor. The suffix -TFD-558indicates that this compressor comes pre-equipped with key accessories from the factory, forming a "ready-to-use" or "modular" compressor unit solution. This significantly simplifies on-site installation and enhances system reliability.

Suffix Code Breakdown

TFD:This typically represents a set of pre-installed accessory combinations. Specifically, it includes:

T - Crankcase Heater:Standard equipment to prevent refrigerant from dissolving into the oil during shutdown.
F - Suction Muffler:Reduces suction noise for quieter operation.
D - Discharge Muffler:Reduces discharge pulse noise.

558:This usually refers to the specific model or specification of the pre-installed suction and discharge service valves. These valves allow the compressor to be isolated for maintenance without recovering the refrigerant from the entire system.

Main Technical Parameters (Typical values, example for R404A/R507)

Parameter	Description
Model Type	Semi-Hermetic Piston Compressor with Accessories (High-Efficiency)
Number of Cylinders	4
Displacement	Approx. 19.1 m³/h
Rated Power	Approx. 2.2 kW (depends on operating conditions)
Common Refrigerants	R404A, R507, R448A, R449A, R134a, etc.
Refrigeration Oil	Synthetic Oil (e.g., POE), Oil charge refers to manual

Features and Characteristics (In addition to standard ZB19KQE features)

Ready-to-Install:Pre-installed key accessories (mufflers, valves) save time and cost associated with sourcing and installing these parts on-site, reducing potential leak points.
Easy Maintenance:The pre-installed suction and discharge service valves make subsequent compressor maintenance or replacement very convenient, without the need to evacuate the entire refrigerant charge from the system.
Quiet Operation:Integrated suction and discharge mufflers effectively reduce gas flow noise, resulting in quieter operation of the compressor unit, suitable for noise-sensitive environments (e.g., supermarkets, convenience stores).
Retains All High-Efficiency Features:Possesses all the advantages of the ZB19KQE, including the high-efficiency motor, optimized valve plate design, built-in motor protection (PTC), etc.

Primary Application Fields

Due to its compact and convenient nature, the ZB19KQE-TFD-558 is ideally suited for the following applications:

Commercial Display Cases:Supermarket island cases, deli counters, refrigerated vertical cases.
Small Cold Storage Rooms:Small refrigerated and frozen storage rooms used in restaurants, hotels, and laboratories.
Modular Refrigeration Units:Serves as the core of pre-assembled refrigeration units, integrated directly into equipment.
Convenience Refrigeration Systems:Refrigeration equipment for convenience stores.

Selection and Usage Considerations

System Matching:Despite coming with accessories, selection calculations based on actual operating conditions (evaporation temperature, condensation temperature) are still essential.
Space Consideration:The pre-installed valves and mufflers increase the overall dimensions of the compressor. Sufficient space must be reserved in the installation layout.
Professional Operation:Operation of the service valves, system evacuation, and refrigerant charging must still be performed by qualified personnel.

Summary

The ZB19KQE-TFD-558 is not just a compressor; it is a complete functional compressor unit solution. By pre-installing key accessories, it offers users greater installation efficiency, maintenance convenience, and operational reliability. It is an excellent choice for projects prioritizing rapid deployment, low on-site installation costs, and system stability.
