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.

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.

Danfoss Compressor Model Code Chart: Quick Reference Guide for HP, Watts & Amps

When a refrigerator or freezer arrives at the workshop with a worn nameplate or faded sticker, identifying the compressor becomes a guessing game. The Danfoss and Secop hermetic compressor model codes—such as TFS 4 AT, FR 8.5A, or SC 18B—tell you exactly what you’re dealing with if you know how to read them. This chart breaks down those cryptic codes into simple horsepower, watt consumption, and amp ratings so you can diagnose problems, choose the right replacement, or estimate expected power draw in seconds.
What the Model Code Actually Tells You
Every Danfoss and Secop compressor code hides three critical pieces of information that technicians need daily: the horsepower class (from 1/8 hp to 5/8 hp for small units), the power consumption in watts, and the running current in amperes. These values come straight from standardized testing under EN12900 conditions, though real-world consumption will shift with ambient temperature, refrigerant charge level, and how often the thermostat cycles the compressor on and off.
Understanding these numbers transforms a worn-out compressor into useful data. You stop guessing and start troubleshooting with confidence. If your clamp meter shows 2.8 amps but the chart says the model should draw 1.2 amps, something is wrong—perhaps the compressor is flooded with liquid refrigerant, the motor is failing, or the system is simply overcharged.

These figures are approximate starting points. Always download the official Danfoss or Secop technical datasheet for your exact model and refrigerant version before making critical decisions about compressor sizing, capillary tube replacement, or system overhaul.
The Three Compressor Families: TL, FR, and SC Explained
Not all small Danfoss hermetic compressors work the same way. Three distinct product families dominate the market, each optimized for different cooling loads and cabinet types. Swapping between families without understanding their differences can cause short cycling, liquid floodback, high starting current, or simply insufficient cooling.
Universal workhorse, handles LBP/MBP/HBP, wide evaporating window (−30 °C to +10 °C), multiple refrigerants (R134a, R404A, R507)
SC Series
SC18G, SC18B, SC21G
280–470+ W
Heavy-duty freezers, cold rooms, demanding loads
Higher displacement, cooling capacity up to ~1950 W at some points, suited for commercial-grade duty cycles
The practical lesson: A TL4G and an SC18B both carry a Danfoss nameplate, but they’re worlds apart in displacement, starting current, and cooling power. Plugging an SC18B into a system designed for a TL4G creates an instant overcharge and liquid migration problems. Conversely, installing a TL4G in place of a failed SC18B leaves your customer’s freezer unable to maintain temperature.
How Technicians Use This Chart in Daily Work
Diagnosing a Mystery Compressor
Imagine you open up an old ice cream freezer or reach the back of a forgotten wine cooler and find a compressor with no readable nameplate—just a bare black shell with a yellow identification sticker. The model number might be partially visible: perhaps you can make out “FR8.5” or “SC18”.
This chart lets you instantly know that an FR8.5 B will draw around 155 watts and 1.2 amps during steady running. You clamp the power lead and measure 2.1 amps instead. That’s a red flag—the motor is working harder than it should. Possible causes: overcharge of refrigerant, flooding of oil and liquid into the crankcase, worn motor bearings, or a faulty capacitor causing inefficient starting. Instead of blindly replacing the compressor, you now have a diagnostic direction.
Selecting a Replacement
When a customer’s 10-year-old refrigerator needs a new compressor, you have options. Should you stick with the original FR 8.5 A, upgrade to an FR 8.5 B, or jump to an SC 12 A?
The chart helps you think this through:
Same family, same size: An FR 8.5 B replacement (≈155 W) in place of a failed FR 8.5 A (≈155 W) keeps system design intact.
Efficiency upgrade: A newer high-EER FR 8.5B or TL5G consuming 10% less power but delivering the same cooling might save your customer 15–20% annually on electricity.
Oversizing trap: Moving from FR 8.5 (155 W) to SC 12 A (250 W) sounds like added cooling power, but without redesigning the capillary tube, expansion device, and charge volume, you risk liquid slugging and compressor failure within weeks.
The chart is your reality check. It shows displacement boundaries that shouldn’t be crossed carelessly.
Cross-Referencing Between Brands
Not every customer uses Danfoss. A competitor’s 1/4 hp compressor running R134a might be perfectly comparable to an FR 8.5B if the cooling capacity, motor winding, starting current, and duty cycle align. The chart becomes your baseline—a reference point for comparing specs across manufacturers when a customer insists on a different brand or when supply is tight.
Real-World Cooling Capacity Behind the Watt Numbers
Power consumption (watts) is not the same as cooling capacity (watts of refrigeration). A compressor drawing 155 watts of electrical input might deliver 400–600 watts of cooling capacity depending on the evaporating temperature, condensing temperature, and refrigerant type.
This is why the chart lists electrical input, not cooling output. When a customer asks, “Will this compressor keep my freezer cold?” you need the full technical datasheet—not just this quick-reference chart—to answer properly. The chart gets you in the door; the datasheet closes the sale.
Common Mistakes Technicians Make with Compressor Charts
Mistake 1: Assuming “5/8 hp” compressor is always better than “1/2 hp” An SC 18B (5/8 hp, 470 W) delivers more cooling than an SC 15 A (1/2 hp, 315 W), but only if the system is properly designed for it. Oversizing without adjusting capillary tubes and refrigerant charge causes short cycling and inefficiency.
Mistake 2: Ignoring refrigerant type and duty rating An FR 8.5 A rated for R134a in LBP service is not the same as an FR 8.5 A rated for R404A in HBP service. The motor windings, displacement, and performance curves differ. Always match refrigerant and duty code.
Mistake 3: Mixing current (amps) with cooling capacity A compressor drawing 4.2 amps (like the SC 18B) will trip a standard 15-amp residential circuit faster than an FR 8.5 (1.2 A) if run continuously. Circuit protection, wiring gauge, and contactor sizing must all account for this difference.
Mistake 4: Using only the chart without the datasheet This chart is a diagnostic shortcut, not a design tool. For new installations, retrofits, or capacity upgrades, download the official technical data showing performance curves, cooling capacity at different evaporating/condensing temperatures, and refrigerant charge recommendations.
Why This Chart Matters for Your Bottom Line
When you can quickly identify a compressor, estimate its power draw, and recognize whether it’s being overloaded or oversized, you reduce diagnostic time, avoid costly misdiagnosis, and build customer trust. A technician who says, “Your compressor is drawing 30% more current than it should—we need to check the charge level before replacing anything” sounds more professional than one who immediately orders a replacement part.
The chart also protects you from expensive warranty claims. If you install a SC 18B in a system designed for an FR 8.5, and it fails in three months due to liquid floodback, you’re liable. The chart is your documentation that you understood the difference.

Against ACC GL80AN, the Samsung unit generally has slightly lower displacement, making it better suited to compact cabinets where low noise and reduced energy use are more critical than maximum capacity.
Practical exploitation, reliability and installation tips
In workshop practice the Samsung SD162H‑L4UA S01 is appreciated for:
Strong load capacity during pull‑down of warm cabinets, inherited from the SD162 series design.
Reliable starting performance thanks to the RSCR/RSIR motor concept combined with an internal thermal protector.
Low noise and vibration, making it acceptable for domestic kitchens and small commercial premises.
When using this compressor as a replacement:
Match refrigerant (R134a), voltage, and application range (LBP) to the original unit to avoid overheating and low capacity.
Keep suction line sizing close to Samsung recommendations in general catalogs to preserve return gas cooling and oil return.
Use clean‑brazing practice and always replace the filter‑drier after opening the circuit to protect the compressor against moisture and acids.

This table shows why the MTZ160HW4VE is positioned as a 13 hp‑class compressor for large medium‑temperature duties rather than domestic or small commercial equipment. The internal overload, POE 160PZ oil, and 22.6‑bar shell rating give it the safety margin needed for high‑pressure HFC blends like R404A and R507A.
Field applications and exploitation potential
Because of its capacity and three‑phase motor, the MTZ160 series is frequently installed in:
Medium‑temperature cold rooms for food storage in supermarkets and restaurants.
Process chillers, milk tanks, and air‑dryer systems that need stable evaporating temperatures and long run times.
For installers, the multi‑refrigerant capability is a real advantage: the same MTZ160HW4VE shell can be used with traditional R404A/R507A or retrofitted to lower‑GWP blends like R448A or R449A, provided the system is re‑calculated using Danfoss performance software. The POE 160PZ oil ensures full miscibility with HFC and HFO blends, which is essential for good oil return in long piping runs and vertical risers in supermarket systems.
Value comparison with another Maneurop and Copeland models
To position this compressor on the market, it is useful to compare it with a smaller Maneurop MTZ80‑4VI and with a scroll alternative such as a Copeland ZR81KCE.

Against a similar‑capacity Copeland scroll, the reciprocating design may be a bit noisier but offers higher displacement and strong performance at lower evaporating temperatures, making it attractive in heavy commercial refrigeration.
Medium‑temp, usually not as deep at low evaporating.
Similar condensing limits depending model.
Some models have narrower approved refrigerant lists.
From this table, the MTZ160HW4VE stands out by its very wide refrigerant portfolio, which is a strong value for installers looking for future‑proof solutions during HFC phase‑down. Scroll compressors remain strong competitors in efficiency and sound level, but they are not always as tolerant to liquid slugging or deep evaporating conditions as a rugged reciprocating Maneurop.
Installation, reliability and service notes
Danfoss guidelines for MT/MTZ compressors specify that these units must be installed with proper crankcase heaters, suction line filters, and accurate superheat control to avoid liquid floodback. They also recommend limiting the number of starts to around 12 per hour and ensuring correct phase rotation and voltage balance to protect the three‑phase motor.
During service, only POE 160PZ oil should be used, and charging must be done as a liquid from the cylinder when handling zeotropic blends such as R407C, R448A, or R449A to prevent fractionation. When retrofitting from R404A to a lower‑GWP blend, system components such as expansion valves and line sizes must be checked against the new operating pressures and mass flow predicted by Danfoss software tools.

Application examples and exploitation in the field
In practice, the KCE444HAG is commonly installed in:
Water coolers between 40 and 80 liter nominal storage.
Bottle coolers and small commercial beverage merchandisers operating in high or medium temperature ranges.
For water coolers, the compressor offers enough capacity to chill drinking water quickly while keeping energy consumption moderate, thanks to its roughly 475 W input at high‑back‑pressure conditions. In bottle coolers, the wide evaporating envelope from negative temperatures up to more than +10°C allows flexible control of cabinet temperature without putting the compressor outside its design limits.
Performance comparison with similar compressors
To understand the real value of the KCE444HAG, it is useful to compare it with another well‑known R134a hermetic compressor such as the GL90AA (ZMC EGL90AA) widely used in domestic and light commercial refrigeration.

The table shows why the KCE444HAG is chosen for positive temperature applications like water coolers, while the EGL90AA works better in freezer‑type systems requiring lower evaporating temperatures. Selecting the wrong compressor for the required evaporating range can lead to high discharge temperatures, low efficiency, and premature failure.
Installation, reliability, and service considerations
The KCE444HAG compressor must be operated inside the condensing and evaporating temperature envelope defined by the manufacturer to guarantee long service life. The datasheet specifies that performance values are valid only inside this envelope and also gives maximum allowable internal moisture and solid residue limits, emphasizing the need for clean, well‑evacuated systems.
Technicians should:
Use R134a only and charge with the correct POE oil volume if a major repair requires oil replacement.
Keep the mounting angle within the 5° limit and respect guidelines for handling and disposal listed in the detailed product documentation.
Good airflow around the compressor and condenser, combined with properly sized capillary or expansion valve, keeps shell temperature and discharge pressure under control, further improving reliability in continuous water‑cooler duty.
