GMCC PE90HME‑4 hermetic compressor
Mbsmpro.com, Compressor, PE90HME‑4, 1/3 hp class, GMCC, Cooling, R134a, 265–295 W, 1.55 A, 1Ph 220‑240V 50/60Hz, LBP capacity, RSCR motor, −23.3°C to −10°C
The GMCC PE90HME‑4 is a hermetic reciprocating refrigerator compressor optimized for R134a and low‑back‑pressure applications at 220–240 V, 50/60 Hz. With a displacement of about 9.0 cm³ and catalog cooling capacities between 265 and 295 W around freezer conditions, it sits in the 1/3 hp performance class and targets domestic and light commercial refrigerators.
GMCC PE90HME‑4 technical identity
The label identifies the compressor as thermally protected, RoHS‑compliant and designed for R134a static‑cooling appliances. It belongs to the PE series of GMCC light commercial units produced by Anhui Meizhi Compressor Co., Ltd.
Nameplate and catalog data
The RSCR motor concept means a start capacitor is used only during start while a smaller run capacitor remains in circuit, balancing starting torque, efficiency and cost for fractional‑horsepower refrigeration.
Operating envelope and performance
GMCC’s reference data for the PE90H1F‑4 and PE90HME‑4 show nearly identical working limits, giving a clear view of the envelope in which this compressor is expected to operate. These limits are critical for system designers who must match capillary length, condenser size and evaporating temperature.
Operating limits
| Parameter | Typical PE90HME‑4 values |
|---|---|
| Evaporating temperature range | −35 °C to −10 °C (LBP) |
| Nominal rating point | −23.3 °C evap / 32.2 °C ambient / 55 °C condensing |
| Voltage range | 187–254 V (50 Hz) |
| Ambient temperature range | 0–43 °C |
| Max condensing temperature | 60–70 °C |
| Max discharge gas temperature | 130 °C |
| Max winding temperature | 130 °C (internal) |
| Max pump‑down pressure | ≈ 1.82 MPa |
At the nominal point the compressor typically delivers around 265 W at 1.55 A, while higher ambient or less negative evaporating temperatures move capacity closer to 295 W but also increase power input. GMCC specifies vibration levels below 4.9 m/s² and sound levels compatible with household refrigerator noise expectations.
Comparison with other GMCC R134a PE series models
To position the PE90HME‑4 correctly for selection and replacement, it helps to compare it with nearby models such as PE65H1H‑9 and PE90H1F‑9 from the same GMCC R134a range.
GMCC R134a LBP models – performance comparison
*Capacity values taken at −23.3 °C evap / 32 °C amb., minor differences by catalog edition.
Compared with the PE65H1H‑9, the PE90HME‑4 delivers roughly 40–50% more capacity at similar current, making it better suited to 280–400 L refrigerators or small freezers that need stronger pull‑down. Against the PE90H1F‑9, performance is very close; differences are mainly in voltage tolerance (wide‑range versions) and detailed application approvals rather than raw capacity.
Practical applications and selection tips
Designers and technicians usually choose the GMCC PE90HME‑4 when they need a robust, mid‑size R134a compressor that balances capacity, energy efficiency and cost. It is especially attractive in markets where 220–240 V 50 Hz is standard and where appliances are exposed to high ambient temperatures.
Typical uses
- Static‑cooling household refrigerators in the 300–400 L range.
- Upright or chest freezers requiring −23 °C design evaporating temperature.
- Commercial beverage coolers and display cases using R134a and capillary expansion.
Selection and replacement considerations
| Checkpoint | Why it matters |
|---|---|
| Refrigerant | Must be R134a; conversion from R12 or R600a requires full system redesign. |
| Evaporating temperature | Ensure design conditions fall inside −35 to −10 °C LBP range. |
| Condenser and capillary sizing | Match to 265–295 W capacity to avoid flood‑back or high‑head faults. |
| Voltage stability | Mains should remain within 187–254 V; more unstable grids may justify wide‑voltage models like PE90H1F‑9. |
| Start components | RSCR start kit (PTC + capacitor) must match GMCC’s specified values to guarantee torque and reliability. |
