Zingfa Compressor Models: A QR and QL Series Selection Guide

Zingfa (Xingfa) is widely used in cold storage plant, cold rooms and commercial refrigeration packs, with hermetic piston compressors from 2 HP to 7 HP. The balance of output against price makes them a common choice for condensing unit builds in particular. This guide covers the difference between the QR and QL series, how to read the model codes, and the full model list by capacity.

What is the difference between the QR and QL series?

• QR series: the main series, used for standard commercial refrigeration and chilled storage. This is the most common choice for cold rooms and condensing units.
• QL series: the models marked LBP (low back pressure, meaning a low evaporating temperature). Designed for deep freezing and low temperature cold storage applications.

How to read a Zingfa model code

• A “3” indicates the phase: QR3 and QL3 models run on a three-phase 380V supply, while QR and QL models without the “3” run on a single-phase 220V supply.
• The number rises with capacity: 44 → 2 HP, 58 → 2.5 HP, 74 → 3 HP, 90 → 4 HP, 112 → 5 HP, 124 → 6 HP, 134 → 7 HP.
• “VAN.” (valved): a body with service valves on the suction and discharge lines, which makes installation and servicing easier. Every Zingfa model in the TURA catalogue is valved.
• Refrigerant: every Zingfa model in our catalogue runs on R404A.

Zingfa compressor models by capacity

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:

• 2 HP: Zingfa QR3-44
• 2.5 HP: Zingfa QR3-58, Zingfa QL3-52 (LBP)
• 3 HP: Zingfa QR3-74, Zingfa QL3-74 (LBP)
• 4 HP: Zingfa QR3-90
• 5 HP: Zingfa QR3-112, Zingfa QL3-112 (LBP)
• 6 HP: Zingfa QR3-124
• 7 HP: Zingfa QR3-134, Zingfa QL3-134 (LBP)

Single-phase or three-phase?

That depends on the electrical supply at the site. Where a 380V three-phase supply is available the QR3 and QL3 series are the choice; smaller premises with only a 220V single-phase supply use the QR and QL models. Both phase options are held in our catalogue at the same HP ratings.
