The Embraco PW 5.5 K11W stands as a testament to the enduring engineering of the Brazilian manufacturing era. Designed as a Low Back Pressure (LBP) hermetic reciprocating compressor, this model has long been a staple in domestic refrigeration systems, specifically those engineered for the R12 refrigerant cycle. While the industry has shifted toward R134a and R600a, the PW series remains a critical component for technicians maintaining vintage systems or specific industrial cooling setups that require high-torque reliability in a compact frame.

Technical Specifications and Performance

The PW 5.5 K11W is characterized by its robust electrical profile, capable of operating across both 50Hz and 60Hz frequencies. This versatility makes it unique compared to many modern compressors that are locked into a single frequency. With a displacement that typically aligns with 1/6 horsepower (HP) performance, it provides a cooling capacity of approximately 133 Watts (454 Btu/h) under standard ASHRAE conditions.

Feature	Specification Details
Model	Embraco PW 5.5 K11W
Refrigerant	R12
Horsepower	1/6 HP
Voltage/Frequency	220-240V / 50/60Hz
Cooling Capacity	133 W (at -23.3°C)
Application	LBP (Low Back Pressure)
Locked Rotor Amps (LRA)	11.5 / 10.4 A
Motor Type	RSIR (Resistive Start – Induction Run)
Origin	Joinville – SC, Made in Brazil

Operational Comparisons: PW 5.5 vs. Modern Alternatives

When comparing the Embraco PW 5.5 K11W to modern equivalents like the EMR 40HLR or the ZMC GM70AZ, we see a significant evolution in energy efficiency. However, the PW series is often preferred by specialists for its thermal protection resilience. The internal “Thermally Protected” mechanism in the PW 5.5 is designed to handle the higher heat loads associated with older R12 systems without premature failure.

Compressor Model	Power (HP)	Refrigerant	Cooling Type	Cooling Cap (W)
Embraco PW 5.5 K11W	1/6	R12	LBP	133
Embraco EMT45HDR	1/6	R134a	HBP/LBP	155
Danfoss PL35F	1/10	R134a	LBP	85
Tecumseh THB1340YS	1/8	R134a	LBP	105

The Role of the PW 5.5 in Maintenance and Retrofitting

Finding a direct replacement for an R12 compressor requires attention to displacement and oil type. The PW 5.5 K11W utilizes Mineral Oil, which is compatible with CFC refrigerants. If a technician is attempting to retrofit a system using this compressor to R134a, a complete oil flush and replacement with POE (Polyolester) oil are mandatory. However, for those seeking to maintain original system integrity, the PW 5.5 remains the gold standard for 1/6 HP LBP requirements.

Troubleshooting and Electrical Data

The LRA (Locked Rotor Amps) values of 11.5 and 10.4 are critical for identifying starting issues. If the compressor hums but fails to start, checking the starting relay and capacitor (if applicable) is the first step. Because this is an RSIR motor, it relies on a high-resistance start winding to initiate rotation, making it sensitive to voltage drops in the power supply.

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.

1. Vacuum Deeply: Ensure the system is evacuated to at least 500 microns to remove all moisture that could react with the POE oil.
2. 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.
3. 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.
