Konor GQR16TG Hermetic Compressor – 1/2 HP, R134a, 1,450 W / 4,948 BTU/h

Konor GQR16TG is a hermetic reciprocating refrigeration compressor with 1/2 HP power, running on R134a refrigerant. It delivers 1,450 W (4,948 BTU/h) cooling capacity under ASHRAE conditions. It is made for light commercial refrigeration applications such as commercial refrigerators, display cabinets and display counters.

Light Commercial Hermetic Reciprocating Compressor

The compressor is fan-cooled and operates in circuits throttled by a capillary tube. Its evaporating temperature range is −15 … +10 °C — which makes it suitable for positive-temperature (HBP/MBP) applications, i.e. cooler cabinets rather than freezers.

Under what conditions was the capacity measured? The 1,450 W value above was measured under the manufacturer's ASHRAE test conditions: evaporating +7.2 °C, condensing +54.4 °C, suction gas 35 °C, ambient 35 °C. The same compressor delivers noticeably less capacity at a lower evaporating temperature — so the HP value alone is not a basis for comparison; look at the W and BTU values.

• ⚠️ The run (permanent) capacitor is not included in the box. This model has a CSR motor; it requires a 15 µF run capacitor to operate. The manufacturer's accessory list includes the start capacitor (80 µF) but not the run capacitor — it must be obtained separately: 15 µF run capacitor.
• Box contents: compressor, overload protector, start relay, start capacitor, motor terminal cover and clip, 4 anti-vibration mounts, 4 mounting sleeves.
• 🔧 Installation: The compressor operates upright; it must not be mounted without the anti-vibration mounts. Wrap the body in a wet cloth when brazing the tubes, as excessive heat damages the winding insulation.
• 🔧 Oil compatibility: POE oil absorbs moisture. Do not remove the compressor's suction plug until the moment of installation; the oil of a compressor left open absorbs moisture and acid forms in the circuit.
• ⚠️ Refrigerant compatibility: This model is for R134a. It must not be operated with high-pressure refrigerants such as R404A.
• Before commissioning, evacuate the system; a compressor must not be replaced without also renewing the capillary tube and filter drier.
