The Engineering Standard: Embraco EM2Z 80HL.C Technical Analysis

In the demanding world of commercial and domestic refrigeration, the Embraco EM2Z 80HL.C stands out as a reliable workhorse. Manufactured in Brazil, this hermetic reciprocating compressor is designed to meet the rigorous standards of modern cooling appliances. As refrigeration technicians seek precise data for repairs and replacements, understanding the core specifications of the EM2Z series becomes paramount for ensuring system longevity and efficiency.

This unit is specifically calibrated for Low Back Pressure (LBP) applications, making it an ideal choice for freezers, refrigerators, and display cabinets that require consistent temperature maintenance between -35°C and -10°C.

Detailed Technical Specifications

The EM2Z 80HL.C utilizes a high-efficiency motor configuration compatible with 220-240V at 50Hz power sources. Its internal architecture balances displacement with energy consumption, offering a streamlined solution for 1/4 HP refrigeration circuits.

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.

Copeland ZB50KCE Scroll Compressor Nameplate: How to Read the Label and Choose the Right Polyester Oil

The photo shows the damaged nameplate of a Copeland ZB50KCE scroll compressor, factory‑charged with polyester (POE) oil for medium‑temperature refrigeration. Correctly interpreting this label helps technicians confirm oil, power, voltage and safety limits during service or replacement.​

Compressor identification

The model belongs to the Copeland ZB series, used in commercial cold rooms and process cooling for refrigerants such as R404A, R134a and R22 alternatives. Depending on voltage code (TFD‑551, TFD‑950, etc.), it is sold as a 7 hp medium‑temperature compressor with around 11.9 kW nominal capacity.​

• Model code example: ZB50KCE‑TFD‑551 or ZB50KCE‑TFD‑950.​
• Technology: Hermetic scroll, part of the Summit series designed for higher seasonal efficiency.​

Polyester oil (POE) on the label

The upper part of the label still shows POLYESTER OIL, confirming that the compressor is charged with POE lubricant. Catalogues list oil charges of about 2.6–2.7 l using approved POE types such as RL32‑3MAF or Mobil EAL Arctic 22 CC, depending on the variant.​

• POE oil absorbs moisture quickly, so systems must be evacuated deeply and fitted with quality filter‑driers.​
• Only compatible POE grades should be added; mixing with mineral or alkylbenzene oil is not permitted.​

Technical data with hp and W

The following table compiles typical data for a Copeland ZB50KCE‑TFD‑551 running as a medium‑temperature refrigeration compressor; values may vary slightly by refrigerant and exact model.​

Parameter	Typical value for ZB50KCE*
Nominal power	7 hp​
Nominal capacity	11.9 kW cooling (≈11 900 W)​
Electrical power input	≈7.5–7.9 kW depending on conditions​
Displacement	19.8 m³/h​
Supply voltage	380–420 V/3/50 Hz and 460 V/3/60 Hz (TFD code)​
Maximum operating current	14.6 A​
Locked‑rotor current	≈100 A​
Oil type	POE (e.g. RL32‑3MAF)​
Oil quantity	2.6–2.7 l​
Sound level	≈64 dBA at 1 m​
Net weight	≈59 kg (TFD‑551)​

*Always confirm with the exact data sheet for your compressor code.​

Voltage and operating limits on the sticker

On the lower part of the photographed label, remnants of “Volt 1 380 … Volt 2 460” can be identified, matching the dual‑voltage three‑phase motor used in TFD models. Another line mentions maximum current around 14.6 A, which is the value used to size breakers, contactors and cables.​

• The TFD motor code indicates 380–420 V/3/50 Hz and 460 V/3/60 Hz with internal motor protection.​
• Respecting these limits and using proper overload protection prevents overheating and nuisance trips in commercial installations.​

Practical maintenance notes

For technicians such as those in Mbsmgroup and Mbsm.pro, a faded nameplate is common on older units, but the combination of model code and official catalogue restores all critical information. Creating a new service label with hp, kW, voltage, POE oil type and charge simplifies future troubleshooting and reduces the risk of mistakes during oil changes or retrofits.​

• When replacing or topping up oil, always isolate the compressor, recover refrigerant and work under clean, dry conditions.​
• If in doubt about capacity or application limits, refer to the Copeland ZB range catalogue and selection software before approving a replacement.​
