Zingfa Compressor Models: A QR and QL Series Selection Guide
Zingfa (Xingfa) is listed in our catalogue with hermetic piston compressors on R404A from 2 HP to 7 HP. This guide covers how the QR and QL series differ in the manufacturer datasheets, how to read the model codes, and the full model list.
What is the difference between the QR and QL series?
The information below is taken from the manufacturer datasheets and the catalogue names of the models.
| QR series | QL series | |
|---|---|---|
| ”Application” line in the datasheet | Medium/high back pressure | Medium/high back pressure |
| Evaporating temperature range of the capacity table | starts at -20 °C | starts at -40 °C |
| Return gas temperature and subcooling of the capacity table | 35 °C, 8.3 K | 32 °C, 0 K |
| Product name in the catalogue | contains LBP |
So the application line is the same in the datasheets of both series; the capacity tables of the QL series cover lower evaporating temperatures. Compare the evaporating temperature of your application with the capacity table of the model. For the capacity values of all Zingfa models, see our article on cold room compressor sizing; for the LBP, MBP and HBP abbreviations, see our guide to LBP, MBP and HBP.
How to read a Zingfa model code
- A “3” indicates the phase: QR3 and QL3 models are for a three-phase 380V supply, while QR and QL models without the “3” are for a single-phase 220V supply.
- Refrigerant: every Zingfa model in our catalogue runs on R404A.
Zingfa compressor models by capacity
The HP rating of each model is taken from its catalogue name.
Single-phase 220V models:
- 2 HP: Zingfa QR-44
- 2.5 HP: Zingfa QR-58, Zingfa QL-52 (LBP)
- 3 HP: Zingfa QL-62 (LBP)
Three-phase 380V models:

Single-phase or three-phase?
The electrical supply must match the voltage, phase and frequency given in the datasheet of the model. Our catalogue has both single-phase and three-phase models at 2, 2.5 and 3 HP; the catalogue models of 4 HP and above are three-phase only.
