This model is manufactured in Egypt and is widely compatible with fridges operating in regions where 220-240V, 50Hz power is standard

For the EGM91AA (LBP, R134a), the answer leans more to freezing / low‑temperature cooling, but it is used for both refrigerators and freezers depending on the system design.​

What LBP means

• LBP = Low Back Pressure, which corresponds to low evaporating temperatures, typically about −30 °C to −10 °C.​

• Such compressors are commonly used in freezers, deep freezers, and low‑temperature refrigerator compartments.​

So for EGM91AA

• Its data sheet lists application = LBP with evaporating range −30 °C to −10 °C, exactly the range used for freezer or low‑temperature refrigerator circuits.​

• Practically: if you charge and size the capillary for −25/−30 °C, it works as freezing; if you design around −12/−10 °C, it becomes strong cooling / chiller level.

The EGM91AA compressor from ZMC stands out as one of the most notable solutions in the domestic and light commercial refrigeration sector thanks to its use of R134a refrigerant and its high efficiency under varying climatic conditions. It delivers optimal cooling performance for refrigerators operating on 220–240 V, 50 Hz power, making it a practical choice for both local and international markets. Its advanced technical features translate into quick response, reduced energy consumption, and excellent compatibility with household systems, providing reliable performance backed by solid regional manufacturing.​​

Journalistic introduction

In the fast‑moving world of refrigeration technology, real innovation often hides in the small components that only technicians and specialists tend to notice. At the core of every modern refrigerator, a compressor sets the rhythm for the entire system’s life span and efficiency, and the EGM91AA model is a clear illustration of this principle. A compact steel shell, carefully engineered handling of R134a refrigerant, and optimized power consumption come together to keep food safe and temperatures stable even when ambient heat pushes equipment to its limits.​​

This compressor is more than a metal capsule in a sealed circuit; it is a technical product with a manufacturing story that starts in Egypt and extends across regional markets serving home refrigeration. Designed for 220–240 V, 50 Hz grids and carrying CE conformity, it offers installers and repair professionals a unit that combines robustness, availability of spare parts, and predictable behavior in low back‑pressure applications. As local industries expand their capabilities, models like the EGM91AA show how regional manufacturing can compete in quality while remaining accessible to small workshops and major appliance brands alike.​​

The P14TY is a refrigerant compressor model listed in the provided datasheet, designed for use in refrigeration or air conditioning systems. Below is a summarized technical breakdown of its key specifications:

P14TY Compressor Specifications

Key Observations

1. Refrigerant (R12):
   • The P14TY is designed for R12, an obsolete CFC refrigerant banned under the Montreal Protocol due to ozone depletion. Modern alternatives (e.g., R134a, R404A) require retrofitting or replacement.
2. Applications:
   • Likely used in medium-temperature refrigeration (e.g., commercial refrigerators, chillers) given its capacity and COP at -25°C evaporating temperature.
3. Efficiency (COP 1.73):
   • Lower COP compared to modern compressors, indicating higher energy consumption.
4. Replacement Considerations:
   • If retrofitting for alternative refrigerants, ensure compatibility with oil type (e.g., POE for HFCs) and system components.
   • Verify electrical specs (voltage, starting torque) for new installations.

Testing Conditions (CECOMAF/ASHRAE)

• Evaporating Temp: -25°C (LBP testing for low-temperature applications).
• Condensing Temp: 55°C.
• Ambient Temp: 32°C.

Actionable Recommendations

• For Maintenance:
  • Check oil levels and contamination if still using R12.
  • Inspect capacitors/relays (common failure points in CSIR motors).
• For Replacement:
  • Consider modern equivalents (e.g., Panasonic/Copeland models for R404A/R134a).
  • Consult HVAC technician for system compatibility and retrofitting.
