Copeland Refrigeration Scroll Compressor ZB15KQE-PFJ-558: Technical Data, Performance, Applications and Selection Guide

Summary. The Copeland ZB15KQE-PFJ-558 is a 2 HP hermetic refrigeration scroll compressor from the ZBKQ family. The code decodes to medium temperature application, 15,000 Btu/hr base capacity at 60 Hz, POE oil, a single phase motor, internal inherent protection and the 220-240 V 50 Hz electrical code. Its displacement is 5.9 m3/hr on R404A.

What is the Copeland ZB15KQE-PFJ-558?

The ZB15KQE-PFJ-558 is a Copeland Scroll refrigeration compressor for medium temperature duty. It is built by Copeland, the compressor business formerly operated as Emerson Climate Technologies, and it sits in the ZBKQ product family covered by the ZBKQ for Refrigeration Applications catalogue. That catalogue lists the model under the technical data heading ZB Refrigeration scroll 2-7HP as the entry column of the family, at a nominal 2 horsepower.

Three things about this code drive most of the decisions a buyer has to make, and all three are printed by the manufacturer. The first is the application range letter: B means high and medium temperature refrigeration, which is a different duty class from the low temperature scrolls that carry an injection port. The second is the motor letter: P means a single phase motor, which fixes the electrical supply at 220-240 V on 50 Hz rather than the 380-420 V three phase supply that the same compressor body accepts under a different suffix. The third is the bill of material number, 558, which the manufacturer ties to a brazing or stub tube connection.

The model's own page sits under the Copeland scroll compressor group page, which sits under the scroll compressor category. This guide separates what the manufacturer publishes from what the reseller pages print, because those two sets of numbers disagree on the supply voltage, on the continuous current and on the oil charge. Every figure below is attributed to the document it came from, and the disagreements are recorded rather than smoothed over.

Key facts at a glance

What does the model code ZB15KQE-PFJ-558 mean?

Copeland prints the full structure of this code in the ZBKQ catalogue. The catalogue's nomenclature block reads Z B 76 K Q E - T F D - XXX as the worked example, and the bill of material block then explains the trailing number. Applying that key to ZB15KQE-PFJ-558 gives the following.

The electrical code table is the part that most reseller listings get wrong, so it is worth setting out in full. The catalogue prints six codes against a 50 Hz column and a 60 Hz column.

Two footnotes under that block constrain the build: PFJ is available for ZB15 to ZB29 only, and PFV is available for ZB15 to ZB38 only. The ZB15KQE-PFJ-558 falls inside both permitted ranges.

The letter pair PF therefore carries two separate pieces of information. P states that the motor is single phase. F states that protection is internal and inherent. Neither letter says anything about voltage; the voltage is carried by the trailing J. That distinction matters because the same compressor body is offered as a ZB15KQE-TFD with a T motor letter and a D voltage code, which is a three phase 380-420 V machine.

What are the technical parameters of the ZB15KQE-PFJ-558?

The manufacturer's own technical data table prints one column for the whole ZB15KQ/E model, which covers both the mineral oil KQ build and the POE KQE build. Where the KQ and KQE builds differ, the catalogue separates them, and this model takes the KQE figure.

The catalogued net weight and oil charge are worth pausing on. The catalogue gives 23 kg and 1.3 L for the ZB15KQ/E column. The Emerson per-variant datasheet recorded for the plain ZB15KQE-PFJ build gives 28.12 kg and 1 L, and a distributor product guide for the ZB15KQE-PFJ-524 bill of material gives 23.0 kg and 1.18 L. Those three sets of figures are all in circulation. This guide reports each against its own source and does not merge them into a single weight or oil charge.

Where does the electrical data come from and how does it hang together?

Two documents published by the manufacturer give electrical figures for this code, and they agree with each other once the KQ and KQE build split is respected.

The ZBKQ catalogue prints maximum continuous current, rated load current and locked rotor current as separate rows, each split by motor code. The Emerson per-variant datasheet for the ZB15KQE-PFJ prints the same quantities for the plain build and states the conversion it uses, which lets the catalogue's numbers be checked.

The first three rows explain why the catalogue carries two different rated load currents for the same physical compressor. Copeland derives them from maximum continuous current using two different divisors, one for contactor selection and one for breaker and wire sizing. Neither is the other, and a quotation that shows a single rated load current without saying which divisor produced it is ambiguous.

The fourth row is the one that settles the build question. The catalogue's KQE PFJ continuous current is 18.5 A, which is exactly the figure the Emerson datasheet prints for the ZB15KQE-PFJ. The catalogue's KQ PFJ row prints 16.0 A instead. Since this model's code ends in QE, the KQE row applies, and the value that belongs on this code is 18.5 A with a rated load current of 13.2 A.

What capacity and power does the ZB15KQE deliver on R404A?

The ZBKQ catalogue publishes a full capacity and power grid for the ZB15KQE on R404A at 50 Hz single phase. Capacity is printed as Q in kilowatts and power input as P in kilowatts. The table runs evaporating temperature from -20 to 10 deg C across and condensing temperature from 10 to 60 deg C down.

Capacity, Q in kW, for ZB15KQE on R404A at 50 Hz single phase:

Power input, P in kW, for the same grid:

The catalogue prints three footnotes under this grid: 20 deg C return gas temperature in the non-shaded region, 11 K suction superheat in the shaded region, and 0 K subcooling. The first and third are unambiguous rating conditions. The second identifies a distinction that is carried by shading on the printed page rather than by a value in the cells, so the text layer of the catalogue does not record which cells are shaded.

Dividing capacity by power gives a coefficient of performance at any point where both are printed. The catalogue rounds power input to 0.1 kW, so at the low end of the grid a single rounding step is several percent of the power figure and the derived ratio inherits that. The row below is given as a derived quantity rather than a printed one.

The derived ratio moves steeply with evaporating temperature, which is the expected behaviour of any positive displacement compressor: lifting capacity against a fixed condensing temperature reduces the specific work per unit of refrigeration. Anyone comparing this compressor with a slower running or larger machine should compare at the same condensing temperature and the same evaporating temperature, because the number on its own says very little.

How do the manufacturer's own two sources compare?

The ZBKQ capacity and power grid and the Emerson per-variant datasheet were produced from different programs and do not share a rating point, so they cannot be compared cell by cell. They can be compared by interpolation, and doing that is what establishes that the two documents describe the same machine.

The datasheet rates the ZB15KQE-PFJ at two points: -6.7 deg C evaporating with 48.9 deg C condensing, and 7.2 deg C evaporating with 54.4 deg C condensing, both at 18.3 deg C return gas and 18.3 deg C liquid.

Interpolating the grid to the datasheet points lands within two percent on capacity and within one percent on power, in both directions and at both points. That is close enough to establish that the two manufacturer documents describe the same machine, and far enough from an exact match to show that they were not generated from the same programme. The practical reading is that the catalogue grid predicts the datasheet points well, while neither figure can be substituted for the other in a quotation.

What is the operating envelope of the ZB15KQE?

The catalogue prints operating envelope charts rather than numeric limit tables. For the ZB15KQE to ZB76KQE group on R404A, the chart carries an evaporating temperature axis from -25 to 15 deg C and a condensing temperature axis from 0 to 70 deg C, and it is annotated 20 deg C return gas. The same group appears on a second chart for R134a with an evaporating temperature axis from -20 to 20 deg C and a condensing temperature axis running to 80 deg C, annotated 20 deg C return gas and 11 K superheat.

The boundary of the permitted operating region is drawn as a curve. That curve is a graphic on the printed page and is not carried in the text layer of the document, so this guide reports the axis ranges and the annotations, which are legible, and does not attempt to state the boundary as a set of numeric limits. A buyer who needs the exact boundary should read the chart in the ZBKQ catalogue directly.

Two limits that are printed as values rather than as graphics do apply to this code and are worth carrying into any quotation.

The crankcase heater line is the one that is easiest to overlook. The catalogue prints 70 W for every column in the 2 to 7 HP block, which means the heater is a specified accessory for the whole family rather than an option for the larger sizes only.

What are the performance features that matter on this code?

The ZBKQ catalogue describes the technology in its own words, and three claims in it are specific enough to be worth restating precisely.

The first concerns moving parts. The catalogue states that Copeland Scroll compressors have 70 percent fewer moving parts than reciprocating compressors. Fewer moving parts is the mechanism the manufacturer offers for the reliability and low running cost it claims for the family, and it is also the reason the machine is a candidate where a semi-hermetic reciprocating compressor would previously have been specified.

The second is dual compliance. The catalogue explains compliance as sealing between the orbiting and the fixed scroll involutes, and dual compliance as sealing in both the axial and radial directions. The stated effect is that refrigerant leak back across successive scroll pressure pockets is prevented. The catalogue goes on to state that the compliance design allows the scroll involutes to separate in both the radial and axial directions, which lets debris or liquid refrigerant pass through the involutes without damaging the compressor. The three benefits the catalogue lists for dual compliance are increased efficiency, better liquid handling capability and better handling of debris.

The third is the position of the family in the range. The catalogue states that the newly released ZB large refrigeration scroll compressor expands the ZB product line to 30 HP and is optimised for medium temperature applications for best in class seasonal energy efficiency, and that ZB refrigeration scrolls offer an excellent solution to replacing traditional semi-hermetic compressors. The ZB15KQE is the entry model of that family at 2 HP, so the family-level claims about medium temperature optimisation and about replacing semi-hermetic machines apply to it, while the 30 HP ceiling obviously does not.

Two features of this specific code follow from the model letters rather than from the family text. The E lubricant letter makes it a POE oil machine, so it is the build intended for the HFC refrigerants the envelope charts cover. The 558 bill of material gives it a brazing rather than a rotalock connection.

What refrigerants apply to this code?

The catalogue's operating envelope section groups the family by refrigerant. The ZB15KQE to ZB76KQE group is charted on R404A and again on R134a. The Emerson per-variant datasheet for the plain ZB15KQE-PFJ build names R-404A as its primary refrigerant and lists R-507 as an alternate application at both 60 Hz and 50 Hz, with R-404A and R-507 at 60 Hz on 265 V and R-507 at 50 Hz on 220/240 V.

That last row is the reason this guide does not repeat the site's refrigerant field. The target site prints R404A, R22 and R134A against this model. The manufacturer's own per-variant datasheet for the PFJ build names R-404A and R-507 and does not name R-22; the R-22 entries sit on the TFD sheet, which is the three phase build. A buyer specifying the -PFJ code against R-22 would be relying on a figure that the manufacturer attaches to a different suffix.

Where is the ZB15KQE-PFJ-558 used?

The application range letter on this code is B, which the catalogue maps to high and medium temperature refrigeration. Combined with the capacity grid above, that places the machine in the medium temperature half of commercial refrigeration rather than in frozen storage.

The last two rows matter because the target site's pages describe this model with an application field reading AC, drier, refrigeration and chiller across the board. The catalogue's own application range letter for this code addresses refrigeration, and the family is described as a refrigeration scroll family throughout.

Why choose the ZB15KQE-PFJ-558?

The last row is the one that is easy to miss when reading a single product page. PFJ is offered across the ZB15KQE to ZB29KQE span, which is a 2 HP to 4 HP ladder on one motor type. A project that starts on this code and later needs more capacity can stay single phase, which is not true of every refrigeration scroll family.

How does the ZB15KQE-PFJ-558 compare with its siblings?

The manufacturer's own technical data block prints one column set covering the whole 2 to 7 HP group, which makes a like for like comparison straightforward. The columns below are all the ZB15KQ/E to ZB48KQ/E entries, and the single phase columns are the PFJ values where they exist.

Three readings come out of that table. The first is that the PFJ single phase option stops at ZB29KQ/E, which the catalogue's own footnote states and the technical data rows confirm by leaving the PFJ cells empty from ZB38 upward. The second is that the KQ and KQE continuous currents do not keep the same ordering: at ZB15KQ/E the POE build needs more current than the mineral oil build, and at ZB21KQ/E it needs less. The third is that oil quantity does not rise monotonically with displacement across the group, with 1.3 L at both ZB15KQ/E and ZB19KQ/E and 1.24 L at the larger ZB21KQ/E.

The same compressor body in its three phase form is worth setting beside the single phase build, because that is the comparison a buyer makes when deciding whether to change supply.

The electrical gap is the headline: the three phase build draws 26.0 A locked rotor and 7.0 A continuous where the single phase build draws 58.0 A and 18.5 A. On the two points the datasheets do share, the single phase build is rated at slightly higher capacity and lower power, which gives it the higher coefficient of performance of the two as printed. Those two figures come from the manufacturer's own datasheets for the two suffixes and are the printed values, not derived ones.

What changes between bill of material numbers?

The catalogue's bill of material block lists six numbers against model blocks, and the dimensional drawings then confirm which connection type each number carries.

This code takes 558. The dimensional drawing page for the ZB15 to ZB29 group is headed Brazing with BOM 558, and it prints A 363.8 mm, B 338.3 mm, C 244.5 mm, D 202.9 mm and E 69.6 mm for the ZB15KQ and ZB15KQE entries specifically. Those five dimension letters are particular to the drawing and are not the same letters the catalogue's technical data table uses for its 242 by 242 by 389 mm outline, so the two sets should not be read as one measurement taken twice.

The catalogue's short bill of material list is not exhaustive. The target site carries live pages for this family at bill of material numbers 524 and 559 as well as 558, and a distributor product guide lists the ZB15KQE-PFJ-524 part number with its own weight and oil charge. A quotation that names a bill of material number is naming a configuration, and the number should be matched deliberately rather than treated as a suffix of no consequence.

What do this site's pages say, and where do they disagree with the manufacturer?

This guide is the body of this model's own page on this site. That page carries a specification block, and several of its fields do not agree with the manufacturer's documents for the same code. Each one is recorded here as a discrepancy rather than repeated as a product fact, because a buyer who quotes from the page without checking the manufacturer's table would order the wrong electrical build.

The specification block, the summary list at the top of the page and the page's own sibling pages all carry the same three phase voltage entry for single phase suffix codes. The page for ZB15KQE-TFD-558 prints 380-420 V three phase, which is correct for that suffix, and the page for ZB15KQE-PFJ-524 prints the same voltage although that suffix is also single phase. The pattern is consistent with one electrical field having been copied between pages that describe different suffixes.

A second, separate issue sits in the prose description on those pages rather than in the specification fields. The description block states that vapor injection is used during compression and that the compressor is part of the manufacturer's ZF series with vapor injection for low temperature use, and it states that the line includes four models from 4 to 8 HP. None of that describes this model. The ZB15KQE is a 2 HP machine, and the catalogue's application range code table reserves the injection port letter for a different range letter, listing F as low temperature with an injection port while this code carries B for high and medium temperature. The same description block appears verbatim on the sibling page for the three phase suffix.

The description also lists wide application envelope, part load efficiency technology, enhanced robustness and manifold readiness as key features. The manufacturer's own feature text for this family covers dual compliance, the moving part count and the position of the family in the range, and none of the four listed items appears in it for this code. The manufacturer's catalogue does describe an operating envelope for the group, so that one phrase is not wrong on its own; it is the pairing of it with the rest of the block that makes the block unreliable as a description of this compressor.

For completeness, the site's specification block does carry four entries that the manufacturer's documents support exactly: the 2 HP nominal rating, the 5.9 m3/hr displacement, the 23 kg net weight and the 53 to 58 A locked rotor range. Those four are usable as printed.

What standards, approvals and certification apply?

The catalogue's nomenclature block states that the base capacity figure in the model code is quoted at 60 Hz on an ARI basis, which ties the code's capacity number to the ARI rating framework rather than to an arbitrary figure. Beyond that, the manufacturer's documents used for this guide do not print an approvals or certification list for this code, and this guide does not supply one from elsewhere.

Three of those rows are disclosed rather than verified, and that disclosure is the point. The ISO and the EU regulation addresses did not return readable documents to an automated request on the check date, and this guide states that instead of asserting what they contain. Likewise, the absence of an approvals list in the manufacturer's documents is reported as an absence. A buyer who needs a written declaration for a specific market should request it rather than infer it from a product page.

Global warming potentials quoted in this guide, where refrigerants are compared, come from the Intergovernmental Panel on Climate Change Sixth Assessment Report, Working Group 1, chapter 7: R404A at 3,922 over one hundred years and R134a at 1,526 over the same horizon. Those figures are background for refrigerant choice and are not properties of this compressor.

What should a buyer check before ordering the ZB15KQE-PFJ-558?

1. Confirm the electrical build. Check that the code really ends in PFJ for a single phase 220-240 V 50 Hz supply, or PFV for single phase 208-230 V 60 Hz. If the site being quoted from prints a three phase voltage against a PFJ code, resolve it against the catalogue's electrical code table before releasing the order.

1. Match the continuous current to the correct oil build. Use 18.5 A for a KQE model and 16.0 A for a KQ model. Take the rated load current from the datasheet divisor that matches the device being selected, 13.2 A for contactor selection or 11.9 A for breaker and wire sizing, and do not mix them.

1. Add the run capacitor. A single phase PFJ build is specified with a 40 microfarad, 440 V run capacitor in the catalogue. Treat it as required hardware rather than an optional accessory.

1. Confirm the refrigerant against this suffix. R404A is the primary refrigerant and R507 is listed as an alternate for the PFJ build. If the project needs R-22, check which suffix the manufacturer lists it against, because the datasheet attaches R-22 to the three phase build rather than to this one.

1. Check the evaporating and condensing temperatures against the envelope chart, not against the capacity grid. The grid publishes points, and the chart draws the boundary. A duty point inside the grid but outside the charted envelope is outside the rated region.

1. Fix the bill of material number. 558 is the brazing build for this frame. Where a quotation names 524 or 559 instead, ask which connection arrangement and which accessories that number carries, because weight and oil charge differ between numbers.

1. Check the connection sizes against the pipework. Brazing suction is 3/4 in and discharge 1/2 in for this frame. The rotalock alternative on the same frame is 1-1/4 in suction and 1 in discharge, so the two builds are not interchangeable in a retrofit.

1. Plan for the 70 W crankcase heater. It is printed for every column in the 2 to 7 HP block, so it belongs in the electrical load schedule and in the control sequence.

1. Confirm the mounting interface. The hole pattern is 190 x 190 mm with 8.5 mm holes, and the sight glass fitting uses a 1-1/4 x 12UNF thread.

1. Ask for the sound power and vibration figures in writing if the project needs them. The technical data block does not print a sound power level or a vibration limit for this code, and this guide does not fill that gap from another model.

Frequently asked questions

Is the ZB15KQE-PFJ-558 a single phase or a three phase compressor?

It is single phase. The P in the PFJ motor code is the manufacturer's single phase motor letter, and the J is the electrical code for 220-240 V at 50 Hz and 265 V at 60 Hz. The catalogue's technical data row for the ZB15KQ/E lists 220-240 V single phase against PFJ and 380-420 V three phase against TFD, and the Emerson per-variant datasheet for this suffix is headed 50 Hz, 1 phase, 220/240 V.

Why does a page say 380-420 V for this model?

Because that is the rating of the three phase suffix on the same compressor body, and the single phase 524 build carries the same three phase voltage field. The two suffixes share a displacement, a frame and a bill of material family but not an electrical rating, and a specification field copied between the two pages will carry the wrong voltage. Check the last letter group of the code before trusting a printed voltage.

What is the difference between the KQ and the KQE in this model number?

The single letter E in the lubricant position. A blank there means mineral oil and an E means POE oil. The distinction is not cosmetic: the catalogue prints different rated load and continuous currents for the two builds, 16.0 A and 11.4 A for the mineral oil build against 18.5 A and 13.2 A for the POE build on the same ZB15 frame.

What refrigerant does this code use?

R404A is the primary refrigerant. The catalogue charts the ZB15KQE to ZB76KQE group on R404A and again on R134a, and the Emerson datasheet for the PFJ build names R-404A as primary with R-507 as an alternate application at both 50 Hz and 60 Hz.

How much cooling does it provide?

It depends on the duty point, and the catalogue publishes the whole grid rather than a single figure. On R404A at 50 Hz single phase, capacity runs from 2.1 kW at 60 deg C condensing with -15 deg C evaporating up to 8.6 kW at 30 deg C condensing with 10 deg C evaporating. A single headline number would not describe the machine.

What is its coefficient of performance?

Between about 1.9 and about 5.4 across the 40 deg C condensing row of the catalogue grid, both figures derived by dividing printed capacity by printed power. The catalogue prints power to 0.1 kW, so derived ratios inherit that rounding. The Emerson datasheet prints 2.05 and 2.64 at its own two rating points for this suffix.

Is it suitable for frozen storage?

No. The application range letter on this code is B, which the catalogue maps to high and medium temperature refrigeration. The catalogue's code table reserves the injection port letter F for low temperature duty, and that letter is not present in this model number.

What connection does the 558 mean?

It is the bill of material number. The catalogue associates 558 with the ZB15KQ/E to ZB38KQ/E block, and the dimensional drawing page for that block is headed Brazing with BOM 558. The practical effect is a brazing or stub tube connection with a 3/4 in suction and a 1/2 in discharge on this frame, as against the rotalock alternative at 1-1/4 in and 1 in.

Can it replace a semi-hermetic reciprocating compressor?

The catalogue presents the ZB family as a solution for replacing traditional semi-hermetic compressors, and the same document gives 70 percent fewer moving parts than reciprocating compressors as one of the family's characteristics. Whether a specific replacement works is a system question about capacity at the duty point, connection sizes, electrical supply and envelope, not something the compressor choice settles on its own.

Does it need a run capacitor?

Yes on the single phase build. The catalogue specifies 40 microfarad at 440 V for the PFJ motor on the ZB15KQ/E frame.

How much oil does it hold?

The catalogue prints 1.3 L for the ZB15KQ/E column. A distributor product guide for the ZB15KQE-PFJ-524 bill of material prints 1.18 L instead, and the Emerson per-variant datasheet for the plain PFJ build prints 1 L. The three figures are for three different configurations and this guide does not merge them.

Is the single phase option available across the range?

Only up to a point. The catalogue's footnote states that PFJ is available for ZB15 to ZB29 only, which is a 2 HP to 4 HP span, and the technical data rows confirm it by leaving the PFJ cells empty from ZB38 upward. Above that the single phase option is PFV, which the second footnote limits to ZB15 to ZB38.
