White Whale 540L Black No Frost Refrigerator with Water Dispenser – Full Technical Look with Compressor Power

Reference model and compressor power

The refrigerator in your photos corresponds to the top‑mount White Whale WR‑5395 HBX: a 540‑liter, black, No Frost, 2‑door model with water dispenser and inverter compressor.​
Official and retailer specification pages list the capacity, dimensions, features, and inverter motor, but they do not publish compressor horsepower (HP) or input wattage (W) for this model; only general “energy‑saving inverter motor” information is provided.​

From similar 540L top‑mount inverter refrigerators, the compressor input is typically in the 180–260 W range, which corresponds to approximately 1/4 to 1/3 HP in residential R600a systems, but this is an engineering estimate, not an official White Whale figure.​
For an exact HP or watt rating you would need either the compressor nameplate (inside or on the back of the unit) or a factory data sheet from White Whale’s technical support, because public catalogues for WR‑5395 HBX only state “inverter compressor / energy‑saving motor” without power numbers.​

Updated article with explicit reference

White Whale 540L Black No Frost Refrigerator WR‑5395 HBX with Inverter Compressor and Water Dispenser

The White Whale WR‑5395 HBX is a 540‑liter black top‑mount refrigerator aimed at families who need generous storage, efficient cooling, and a modern look in one appliance.​
It combines a full No Frost system, inverter compressor, digital control and a built‑in water dispenser, making it one of the most attractive options in White Whale’s large‑capacity range.​

Cooling system and compressor

• The WR‑5395 HBX uses a No Frost, multi‑airflow cooling system that keeps a stable temperature and prevents ice build‑up in both freezer and fridge compartments.​
• An inverter compressor modulates its speed according to cooling demand, cutting energy consumption and noise while maintaining fast pull‑down and a quick‑freeze mode in the top freezer.​
• Public datasheets do not disclose the exact compressor HP or watt input, but White Whale and retailer pages only describe it as an “energy‑saving inverter motor” without numeric power ratings.​

Typical power range (engineering estimate)

• Comparable 540L, No Frost, inverter top‑mount refrigerators with R600a usually run compressors rated between 180 W and 260 W, which equates to roughly 1/4–1/3 HP under nominal conditions.​
• This range is offered as a technical approximation based on similar‑size inverter models; for installation, warranty or spare‑part selection, always rely on the actual compressor label or an official White Whale technical sheet for WR‑5395 HBX.​

Main technical specifications

Practical buying notes

This refrigerator suits users who want a large, family‑size fridge with No Frost convenience, inverter efficiency and a black, contemporary finish.​
If you need exact compressor HP or wattage—for example, to size an inverter, voltage stabiliser or replacement compressor—check the compressor nameplate on the back of the unit or request a detailed technical datasheet from White Whale service using the WR‑5395 HBX model code.​

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.​

*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.​

ZMC GL80AF R134a Hermetic Compressor: Technical Profile, Applications and Professional Opinion

The image shows a ZMC GL80AF hermetic compressor designed for domestic refrigeration using refrigerant R134a, manufactured in Egypt and widely used as a 1/5 HP replacement in household refrigerators and coolers. This model belongs to the GL‑AF family of ZMC low‑back‑pressure compressors, optimized for energy‑efficient operation on 220–230 V, 50/60 Hz single‑phase supply in warm climates such as North Africa and the Middle East.​

Main identification

The label in the photo clearly indicates the marking GL80AF, the brand ZMC / ZEM, the refrigerant R134a and the supply range 200–220 V / 220–230 V at 50/60 Hz, with manufacture noted as “Made in Egypt”. In ZMC’s catalog, GL‑series compressors in the 80 class are rated around 1/5 HP, with displacement close to 8 cm³ and low‑back‑pressure duty for freezer and refrigerator applications using capillary tubes.​

Table – ZMC GL80AF key data (typical catalog values for GL80 R134a series)

Technical context and typical uses

Within ZMC’s R134a range, the GL80AF is positioned between smaller GD40/GL45 units and larger GL90 models, offering a balance between cooling capacity and electrical consumption for medium‑size domestic refrigerators and small commercial coolers. Installers commonly use it as a service replacement for 1/5 HP R134a compressors in brands such as Electrolux, Zanussi and regional OEM manufacturers, particularly where a robust compressor is needed for high‑ambient conditions up to 43 °C.​

The GL80AF is designed for use with capillary expansion devices, mineral‑free ester oil compatible with R134a and standard household line voltages, making it straightforward to integrate into existing systems that originally used CFC‑12 or early R134a units of similar capacity. For correct operation, technicians must respect ZMC’s recommendations regarding oil type, charge amount, airflow around the compressor shell and proper matching between evaporator, condenser and capillary tube dimensions.​

Installation, replacement and troubleshooting notes

When replacing a failed compressor with a GL80AF, professionals typically verify that the original unit had a similar displacement and LBP duty rating and then adapt mounting springs, suction and discharge connection diameters if needed. Attention to cleanliness of the refrigeration circuit—nitrogen purging during brazing, filter‑drier replacement and precise R134a charging—is essential to guarantee reliability and avoid lubricant breakdown or acid formation inside the hermetic shell.​

Electrical checks before start‑up usually include measuring winding resistances, confirming the correct RSIR/RSCR starting components (start relay, overload protector and capacitor if required) and ensuring that the supply voltage at the compressor terminals stays within the 187–264 V working range specified for ZMC R134a models. Because GL80‑class compressors are optimized for low back‑pressure, using them outside their intended evaporating temperature range (for example in high‑back‑pressure air‑conditioning duty) can lead to overheating, high current draw and premature mechanical failure.​

Reference images and documentation

Technicians and buyers seeking more visuals can consult ZMC’s official product pages and specialist refrigeration catalogs, which show close‑up images of GL‑series compressors, terminals and mounting hardware. In addition, Mbsmgroup maintains its own photographic documentation and comparison articles featuring the GL80AF in real workshop conditions, including the same type of label as seen in the attached image.​

Several reliable PDF resources provide detailed performance data, cooling‑capacity curves and application limits for ZMC R134a compressors, including GL80‑family models. These catalogs list parameters such as displacement, current, COP, recommended capillary tube sizes and wiring diagrams, giving professionals the information they need to design or repair systems around the GL80AF platform.​

Guide to Common Refrigerants: Standing, Suction and Discharge Pressures for Modern HVAC Systems

Refrigeration technicians today work with a mix of legacy and new-generation refrigerants, each with its own safe pressure range and boiling temperature. Understanding these values is essential for accurate diagnostics, safe charging and long compressor life in air‑conditioning and commercial refrigeration.​

Key role of pressure charts

Pressure–temperature charts and standing/suction/discharge tables give technicians a fast reference for what a system “should” be doing at a given ambient or evaporating temperature.​
Using wrong reference values can lead to over‑charging, overheating, liquid slugging or misdiagnosis of a healthy system as faulty.​

Overview of common refrigerants

The image groups the most used refrigerants in residential and light commercial systems: R22, R134a, R600a, R32, R290, R407C, R404A, R410A and R417 (R417A).​
Each gas has a typical standing pressure (static pressure at rest), an evaporating suction pressure, a condensing discharge pressure and a characteristic boiling point at atmospheric pressure.​

Typical pressure ranges from the chart

The following table summarises the indicative values shown in the chart (all pressures are approximate, for normally loaded systems at typical comfort‑cooling conditions).

Indicative pressures and boiling points

These figures are not universal “set‑points”, but practical targets that help technicians decide whether a system is under‑charged, over‑charged or suffering airflow or mechanical problems.​

Safety, cylinder colours and replacements

Many countries use conventional cylinder colour codes to identify refrigerants quickly on site, although some regions are migrating to neutral colours with clear labelling.​
Hydrocarbons such as R290 and R600a are flammable, so working pressures must always be combined with strict leak‑prevention, ventilation and ignition‑control procedures.​

When phasing out ozone‑depleting R22, blends like R407C or R417A are often used in retrofit projects, while new high‑efficiency equipment typically relies on R410A or R32 with different design pressures.​
Comparing the standing and operating pressures during commissioning helps ensure that a replacement refrigerant is compatible with existing components such as compressors, valves and heat‑exchangers.​

Practical use for technicians and trainers

• Technicians can laminate similar tables and keep them in the toolbox or on the workshop wall as a quick‑reference during charging and troubleshooting.​
• Training centres and HVAC content creators like Mbsmgroup and Mbsm.pro can turn these values into interactive quizzes, infographics or mobile‑friendly charts for students and new technicians.​​

Electrostar 16 foot refrigerator 1/6 HP compressor 125W top freezer Mbsmgroup

Electrostar 16‑Foot Refrigerator: Reliable Cooling With Efficient Compressor Power

The Electrostar 16‑foot refrigerator remains a practical choice for families who want robust cooling, straightforward controls and serviceable components rather than complex smart features. With a capacity around 315–330 liters and a compact footprint, it suits medium‑size kitchens while its small‑horsepower compressor keeps electricity consumption under control in hot climates.​

Design, capacity and layout

Electrostar positions this 16‑foot series in the standard top‑freezer category, giving households a familiar layout that is easy to organize and clean. The cabinet typically offers roughly 315–330 liters of gross capacity, split between a top freezer for frozen food and a larger refrigerator section for fresh produce, drinks and daily ingredients.​

• Adjustable wire or glass shelves let users reconfigure the interior for tall pots, trays or beverage bottles as needed.​
• A full‑width vegetable crisper maintains higher humidity for fruits and vegetables, limiting dehydration over long storage periods.​
• Door balconies provide space for sauces, jars and large bottles so that the main shelves stay free for bulkier items and prepared dishes.​

Cooling system and compressor power (HP & W)

Most 16‑foot Electrostar models are offered in both defrost and No‑Frost versions, but in both cases the “heart” of the system is a low‑horsepower hermetic compressor sized for domestic use. Domestic compressor selection charts show that refrigerators in the 9–13 cubic‑foot (around 283–370 liter) range are normally matched with compressors in the 1/6 to 1/5 horsepower class, consuming about 120–150 watts at rated conditions.​

• A typical 1/6 HP refrigerator compressor corresponds to roughly 120–130 W electrical input, giving enough capacity for a 16‑foot top‑freezer cabinet when paired with an efficient evaporator and insulation package.​
• Independent wattage studies for 16–20 cubic‑foot top‑freezer fridges show average running power between 100 and 400 W depending on design and age, placing a modern Electrostar 16‑foot model toward the lower end of that span when the thermostat cycles the compressor on and off.​
• Some Electrostar variants use branded compressors such as Panasonic, chosen for quieter operation and better efficiency in high‑ambient environments.​

Technical snapshot

Everyday performance and reliability

Electrostar’s 16‑foot refrigerators are built for continuous operation in regions where high ambient temperatures put extra stress on compressors and condensers. The relatively small 1/6 HP‑class compressor may sound modest, but in a well‑insulated cabinet it provides ample cooling capacity while keeping noise and energy bills under control for most households.​

• Mechanical thermostat controls make it simple for users to adjust internal temperatures without dealing with complex digital menus, and they are easy for technicians to diagnose and replace.​
• Service networks in many Arab and North‑African markets stock compatible compressors, starting components and thermostats, which reduces downtime in case of failure and extends the working life of older units.​
• When paired with good ventilation around the condenser and regular cleaning, the compressor can run for many years with stable suction and discharge pressures, even under heavy daily usage.​

Maintenance tips to protect the compressor

Proper maintenance does not just improve hygiene; it also directly protects the small‑horsepower compressor from unnecessary strain and overheating.

• Keep at least several centimeters of clearance around the back and sides of the refrigerator so that condenser coils can reject heat effectively, preventing the compressor from running at high head pressure for long periods.​
• For defrost models, manually defrost the freezer whenever frost thickness exceeds about 3–5 mm, since thick ice forces the compressor to run longer cycles to pull down temperature.​
• Check door gaskets regularly for cracks or gaps; a poor seal allows warm air infiltration, leading to more frequent compressor starts and higher electricity use.​

Helpful external resources

Technicians and advanced users who want deeper technical data can turn to independent references and brand‑agnostic manuals.

• A general household refrigerator user manual in PDF format explains compressor operation, wattage ratings, thermostat settings and recommended clearances that apply to most top‑freezer models.​
• Mbsmgroup also publishes technical sheets and compressor data for various Electrostar units, including power ratings and application notes that help match HP and wattage when selecting replacements.​

Example image and catalog links

• Safe product galleries of Electrostar refrigerators, including 315‑liter and 328‑liter models, are available through regional appliance retailers and show external design, interior shelving and control layouts similar to the 16‑foot series.​
• Technical documentation and catalog PDFs for domestic refrigeration compressors outline HP classes, wattage and typical cabinet sizes, providing useful guidance when evaluating or replacing the compressor in a 16‑foot fridge.

Electrical and performance data

The 156 W ASHRAE rating places the compressor firmly in the 1/6 hp category, widely used for domestic vertical freezers because it balances pull‑down speed with low running consumption.​

Refrigeration circuit: refrigerant, capillary and oil

Official retail pages specify cabinet and compressor wattage but not full circuit details; the following values combine what is published for KH256VF with standard practice for similar Kiriazi no‑frost systems.​

Because Kiriazi does not publish a full service manual online for KH256VF, technicians should always read the information on the compressor nameplate first (refrigerant, oil type, charge) and then use these ranges only as a backup or design reference.​

Practical service notes for technicians

• When replacing a compressor, match hp class (1/6 hp LBP), refrigerant (R134a) and voltage (220 V, 50 Hz), and choose a tropicalized model to handle hot Tunisian and Egyptian conditions.​
• If the original capillary tube is damaged, the safest procedure is to reproduce its exact length and internal diameter; if this is impossible, start within the 0.7–0.8 mm × 2.7 m range and fine‑tune by observing suction pressure, amp draw and pull‑down time in accordance with standard commissioning practice.​​
• Always evacuate to deep vacuum and weigh in the charge whenever the system is opened, especially with POE oil, which is highly hygroscopic and sensitive to moisture contamination.​

This table‑driven overview gives a field‑ready technical picture of the Kiriazi 6‑drawer no‑frost upright freezer, allowing you to plan repairs, retrofits or comparative evaluations with similar vertical deep‑freezer models.​

Zanussi 16 Cubic Feet Refrigerator Compressor GL90AA – 1/4 HP R134a

A 16 cubic feet Zanussi refrigerator typically relies on the GL90AA hermetic compressor, a compact piston unit designed for R134a and low back pressure applications in domestic cooling. This 1/4 HP motor delivers cooling capacities from roughly 165 W up to around 346 W depending on evaporating conditions, which is enough to keep a family‑size fridge and freezer stable even in hot kitchens.​

Technical profile of the GL90AA

The GL90AA is manufactured under the ZMC/Cubigel/Electrolux ZEM family and built specifically for 220–240 V, 50 Hz single‑phase supply used in markets such as North Africa and Europe. It operates in a low back pressure range from about −35 °C to −10 °C evaporating temperature, making it suitable for the freezer section and the fresh‑food evaporator in combined refrigerators.​

Inside its welded shell, a single‑cylinder piston with a displacement of about 9.08–9.09 cm³ compresses the R134a, driven by an RSIR motor controlled by a start relay and overload protector. Static shell cooling, ester oil lubrication (ISO VG 19 or ISO VG 32 depending on version) and a 43 °C maximum ambient rating help the compressor maintain performance and reliability in warm climates where kitchen temperatures can be high.​

Main specifications table

Why Zanussi chooses the GL90AA for 16 ft³

A 16 ft³ Zanussi refrigerator, usually in the 370–425 liter range, combines a generous fresh‑food compartment with a freezer designed to reach well below −18 °C. To maintain those temperatures under frequent door openings, the system needs a compressor that can provide solid capacity at low evaporating temperatures without excessive energy consumption or noise, especially in small apartments and family homes.​

With its 1/4 HP rating, 9 cm³ displacement, and low back pressure characteristics, the GL90AA matches the thermodynamic design of these cabinets, particularly when paired with a correctly sized capillary tube, condenser and evaporator set. Spare‑parts distributors across Europe and the MENA region list GL90AA explicitly as original or equivalent equipment for many Electrolux–Zanussi refrigerator models, confirming its position as a standard solution for this capacity segment.​

Application matching table

Installation and service considerations

Technicians replacing a Zanussi 16 ft³ compressor with a GL90AA must observe best practices to protect the new unit and the customer’s investment. The old R134a charge should be fully recovered, and the filter‑drier replaced with a compatible R134a/POE model to keep moisture and acids under control. Tubes should be cut and brazed under a small nitrogen flow to prevent oxide formation inside the lines, and suction/discharge diameters given in the technical sheet (about 6.5 mm suction, 4.9 mm discharge) should be respected to maintain design capacity and good oil return.​

Because the GL90AA uses ester oil, any contamination with mineral oil from previous generations of compressors must be avoided; if the old system contained mineral oil, thorough flushing or component replacement is recommended. After brazing, the circuit needs a pressure test, deep evacuation to below roughly 500 microns, and precise charging with the mass of R134a specified by Zanussi to secure low noise, correct suction superheat and long compressor life.

Tecumseh CAJ9480T: The French‑Made Heart of Legacy R22 Cold Rooms

On the faded nameplate of this weathered compressor shell, one line stands out with absolute clarity: CAJ9480T – R22/R502 – Made in France. It is the unmistakable signature of a Tecumseh L’Unité Hermétique fully hermetic compressor, a workhorse still beating quietly inside thousands of small cold rooms and refrigerated cabinets around the world.

Identifying the CAJ9480T from the label

The image shows a classic welded‑shell compressor with a rectangular white label fixed on the body and a smaller green Tecumseh/L’Unité sticker below it.
Printed on the label, the model CAJ9480T appears alongside the refrigerant family R22/R502, the voltage range 208–220 V – 50 Hz, and the note THERMALLY PROTECTED, confirming an internally protected single‑phase motor.
The mention Country of origin: France links this unit to Tecumseh’s European manufacturing line, known under the historic L’Unité Hermétique brand, widely used in commercial refrigeration.

Technical profile of the CAJ9480T

Behind this modest steel shell lies a carefully engineered medium‑temperature compressor designed for reliability more than show.

• It is a fully hermetic reciprocating compressor, meaning the electric motor and pistons are sealed in the same welded housing, minimizing leaks and simplifying service on the field.
• In most data sheets the CAJ9480T is rated around 5/8 HP for R22 at 230 V, 50 Hz, suitable for small cold rooms, counters and display cases working in positive temperatures.
• Typical electrical figures published for this model include a Rated Load Amps (RLA) close to 4 A and a Locked Rotor Amps (LRA) around 24 A, values that match the LRA 24 marking on many factory labels.

The following table summarises the key technical characteristics generally associated with a Tecumseh CAJ9480T in R22 applications.

These values are essential for technicians who want to cross‑check compatibility when replacing a damaged unit or when sizing contactors, cables and protections.

Real‑world applications and typical uses

For many shop owners, the CAJ9480T is not a product code but “the compressor in the cold room that never stops”.

• It is widely installed in small walk‑in cold rooms, butcher counters, beverage coolers and positive‑temperature cabinets where cooling capacity around 2 kW at medium evaporating temperatures is sufficient.
• The evaporating temperature envelope usually runs from roughly –23 °C up to +12 °C, allowing the same base model to work in both cooler and slightly higher temperature applications when correctly selected.
• Because R22 has been phased down in many markets, the CAJ9480T often appears in maintenance and retrofit projects: technicians may replace the original compressor with the same reference, or move to compatible alternative refrigerants when regulations and Tecumseh documentation allow it.

In all cases, checking the exact family (CAJ9480T‑FZ, CAJ9480T‑AJ2, etc.) is crucial, as each variant is optimized for specific refrigerants, voltages and accessories.

Installation notes from the field

Even the best compressor will not forgive poor installation. Technicians who work daily with CAJ‑series models usually insist on a few practical rules:

• Clean piping and proper brazing: use nitrogen during brazing, replace the filter drier, and avoid introducing scale or moisture, which can quickly degrade the oil and shorten compressor life.
• Accurate vacuum and charge: a deep vacuum combined with a charge adjusted to sight glass, superheat and manufacturer charts protects the compressor from liquid slugging and overheating.
• Respect of operating envelope: the Tecumseh performance sheets show clear limits for high condensing temperatures and low evaporating pressures; staying inside this window prevents excessive motor current and thermal overload trips.
• Correct starting equipment: since the CAJ9480T uses a CSR motor, the correct run capacitor, start capacitor and potential relay must be installed and wired following the original schematic to avoid hard starts and nuisance tripping.

For older R22 equipment, technicians also need to keep an eye on evolving regulations and encourage owners to plan long‑term upgrades towards more sustainable refrigerants and systems.
