Cubigel GL61AA Hermetic Refrigerator Compressor – 1/5 HP, R134a, LBP 175 W

Cubigel GL61AA (GL 61 AA) is a 1/5 HP hermetic reciprocating compressor manufactured for refrigerators, freezers and small refrigerated cabinets. It runs on R134a; with its 6.0 cm³ cylinder volume it delivers 175 W (597 BTU/h) cooling capacity under the ASHRAE LBP condition. Its RSIR (PTC relay) motor does not require a capacitor; it is also searched for in the field as a "refrigerator motor".

1/5 HP LBP Refrigerator Compressor on R134a: For Refrigerators and Freezers

The GL61AA operates in the −35 … −15 °C evaporating range with its statically cooled body and its design suited to capillary tube systems. With a ≤43 dB(A) noise level and ≤0.8 m/s² vibration value, it is preferred in cabinets that require quiet operation.

Nominal Performance (ASHRAE LBP)

−23.3 °C evaporating / +54.4 °C condensing (ambient, suction and subcooling 32.2 °C, 220 V / 50 Hz): 175 W (597 BTU/h) cooling capacity, 159 W input power, 1.3 A running current, COP 1.10. Capacity decreases as the evaporating temperature falls; make your selection according to your target cabinet temperature.

Electrical Equipment (Manufacturer References)

• Start relay: PTC QP2-12/B3 (max. 8 A · 350 V)
• Overload protector: DRB23P61A1 (6.2 A at 25 °C · trip / reset 125 / 61 °C)

• 🔧 During installation: After the tube plugs are removed, the compressor must be connected to the system within 5 minutes; the plug of the process tube is opened first. The compressor must be mounted horizontally, the tilt must not exceed 5° and the earth connection must be made permanently.
• Application limit: This model is LBP — it is for refrigerator and freezer applications; since it is statically cooled, it is not suitable for fan-cooled high-capacity commercial systems.
