Critical Lubrication Guidelines
One of the most frequent inquiries regarding the EM2Z 80HL.C involves its lubrication requirements. This compressor is factory-charged with 150 ml of Polyolester (POE) oil.
Technicians must strictly adhere to this quantity and oil type. R134a refrigerant requires POE oil due to its chemical miscibility properties. Using mineral oil or alkylbenzene will result in system failure, as these oils do not transport correctly with HFC refrigerants, leading to oil logging in the evaporator and eventual compressor seizure. The ISO 10 viscosity rating ensures the lubricant remains fluid enough to return to the compressor even at low evaporating temperatures.
Comparative Market Analysis
When evaluating the Embraco EM2Z 80HL.C, it is useful to compare it against similar compressors in the 1/4 HP, R134a LBP category. The table below highlights how it stacks up against competitors from Secop (Danfoss) and Tecumseh.
| Feature | Embraco EM2Z 80HL.C | Secop (Danfoss) TL5G | Tecumseh THG1365Y |
|---|---|---|---|
| Nominal HP | 1/5+ to 1/4 HP | 1/6+ to 1/5 HP | 1/5 HP |
| Displacement | 6.76 cm³ | 5.08 cm³ | 5.90 cm³ |
| Voltage | 220-240V 50Hz | 220-240V 50Hz | 220-240V 50Hz |
| Efficiency (COP) | High | Standard | Standard |
| Motor Tech | RSIR/RSCR | RSIR/CSIR | PTCS_CR |
| Oil Type | POE ISO 10 | POE | POE |
Note: The EM2Z 80HL.C often provides a slightly higher displacement than standard “light” 1/5 HP models, bridging the gap toward a full 1/4 HP performance.
Installation and Service Best Practices
For optimal performance, the EM2Z 80HL.C should be installed with a clean, moisture-free system. The POE oil is highly hygroscopic (absorbs moisture), so the compressor plugs should only be removed immediately before brazing.
- Vacuum Deeply: Ensure the system is evacuated to at least 500 microns to remove all moisture that could react with the POE oil.
- Starting Device: This model explicitly states “No Start Without Starting Device.” Ensure the original relay and overload protector (or approved replacements) are used to prevent winding damage.
- Condenser Airflow: As a static or fan-cooled unit, ensure the condenser is free of dust to maintain the head pressure within design limits, preserving the relatively small 5.32 LRA motor from thermal stress.
