Emkarate RL 220H is a polyol ester (POE) refrigeration and air-conditioning lubricant in the Emkarate RL range made by CPI Fluid Engineering, part of The Lubrizol Corporation. The manufacturer publishes a kinematic viscosity of 215 cSt at 40 °C for this grade, which falls inside the ISO VG 220 band (198–242 cSt) defined by ISO 3448, so Emkarate RL 220H is the heaviest grade of the Emkarate RL range. It is listed by the manufacturer for screw compressors and orbital vane rotary compressors on the OEM approvals published for this grade, and the approvals list in its own brochure names CARRIER, HANBELL, McQUAY (J&E Hall), SABROE, VATANU-COOL among the equipment manufacturers that approve it.
What makes this grade checkable is the published table it comes from. CPI publishes the full typical-properties set for every grade in the range — viscosity at 40 °C and at 100 °C to ASTM D445, viscosity index to ASTM D2270, pour point to ASTM D97, density at 20 °C to ASTM D1298, flash point by COC to ASTM D92 and acid value to ASTM D974 — together with an approvals list that names the compressor type and model for each grade. Every figure on this page is reproduced from that document with its method, and the manufacturer's own caveats about the approvals list are reproduced with it rather than dropped.
We manufacture and supply refrigeration and compressor oils at our own blending plant in Foshan, China, and we supply this grade ourselves as QSL-220H, our own ISO VG 220 polyol ester. It ships from Guangzhou Port, which is next to the plant. There is no fixed minimum order — it is confirmed per order, because a single can and a full container load are both workable and the figure moves with the pack size, the quantity and the destination. Delivery is on any Incoterms 2020 term — EXW, FOB, CFR, CIF, DDP and every other rule — and payment is on any commonly used method, including T/T, L/C and PayPal. Send the compressor model, the refrigerant and the oil type on the nameplate and we will confirm the grade against the manufacturer's published data before quoting. QISHANR is a refrigeration oil manufacturer and wholesale supplier, and the grades we list are supplied in bulk to distributors, HVACR service companies and compressor OEMs worldwide.
Emkarate RL 220H is supplied on published terms: the specification, the price terms, the payment terms and the documents are the same for every buyer, and they can be quoted without a site visit. The minimum order is deliberately left open, because it is judged case by case: the grade, the quantity, the pack size, the shipping terms and the container load all move it, so a single can and a full container load are both workable and neither is treated as the normal case. Send us the quantity, the destination port and whether your own brand goes on the container, and those three turn the table below into a firm quotation. Documents and lead time work the same way on every order: the technical data sheet and safety data sheet come with the quotation, and the certificate of analysis for the delivered batch comes with the shipment. This grade is supplied wholesale and in bulk — to distributors, HVACR service companies, compressor OEMs and private-label buyers — as well as in single packs and sample quantities.
| Item | Terms for Emkarate RL 220H |
|---|---|
| Minimum order quantity | Not a fixed figure — confirmed per order, because it is judged case by case: the grade, the pack size, the quantity, the shipping terms and the container load all move it, so a single can and a full container load are both workable |
| Payment terms | Any commonly used payment method — T/T, L/C, PayPal and every other option — confirmed with the order |
| Price terms | Any Incoterms 2020 term — EXW, FOB, CFR, CIF, DDP and every other rule — quoted against your destination port |
| Supply ability | 1,000 pieces per year on this grade, at our blending plant in Foshan — this is the figure for our equivalent, not the annual capacity of the plant |
| Origin | The original Emkarate product, or an equivalent manufactured at our own plant in Foshan, China |
| Supply options | The original Emkarate RL 220H oil, or QSL-220H (our own ISO VG 220 polyol ester), manufactured at our blending plant in Foshan, China |
| Who buys this grade | Distributors and resellers who stock refrigeration oil, HVACR and refrigeration service companies, compressor OEMs filling new equipment, and buyers who need private-label or own-brand packing. Wholesale and bulk orders are the norm; trial and sample quantities are also supplied. |
| Grade confirmation | Send the compressor model, the refrigerant and the oil type on the nameplate. The Emkarate RL range separates its grades by measured viscosity, so the grade is matched on the published 40 °C figure; Emkarate RL 220H is published at 215 cSt, inside the ISO VG 220 band (198–242 cSt), and we confirm that it is the right grade for your machine before quoting. |
| Viscosity | 215 cSt at 40 °C (ASTM D445), which falls inside the ISO VG 220 band (198–242 cSt) defined by ISO 3448, so the grade corresponds to ISO VG 220. Viscosity index 98 (ASTM D2270). |
| Pack size | Confirmed at quotation. The manufacturer states that the RL range is available in a variety of packages, without listing pack sizes grade by grade. We supply the pack format you need, and custom pack formats and private-label artwork are available as a quotation item. |
| Documents issued with the order | Technical data sheet, safety data sheet, and a certificate of analysis for the delivered batch |
| Handling and storage | Store sealed, away from direct sunlight, and keep the container closed between top-ups. A polyol ester absorbs moisture from the air, and moisture is what shortens its service life: at high temperature, in the presence of the ester and the refrigerant, water promotes hydrolysis and the formation of acids. The container should be resealed after every use and the oil should not be decanted into an unlined steel drum where it can pick up rust and moisture. On retrofit, the manufacturer warns that after a mineral-oil charge is drained and replaced with an ester, residual mineral oil can make up as much as 10 percent of the lubricant charge, which can severely affect miscibility, foul or coat the evaporator and reduce efficiency to unacceptable levels. Its instruction is therefore to remove as much mineral oil as possible and to follow its published retrofit procedure. |
Supply ability is stated for this grade rather than for the plant as a whole. It is not the annual capacity of the blending plant.
A lubricant order is rarely only a lubricant order. The buyer is usually solving a grade question, an import documentation question, a freight question and a packaging question at the same time — often across more than one product family. Those are the parts of the job we take on, and they are handled by the same team that quotes the oil rather than passed to a third party.
We are a manufacturer rather than a reseller, which is what makes that possible. The blending plant in Foshan, Guangdong runs at 6,000 tonnes a year and has been producing lubricants for more than ten years, so the answer to most of the questions below comes out of our own production and our own paperwork.
| What you are dealing with | What we do about it |
|---|---|
| The nameplate names an oil type and you need to know what it is equivalent to | Send us the compressor model, the refrigerant and the oil type on the nameplate. We hold the manufacturer's published figures for the Emkarate RL range, so Emkarate RL 220H can be matched on its published 40 °C value of 215 cSt rather than on a description, and we confirm the match in writing before you order. |
| You need the grade, not a catalogue description | Every figure on this page is traceable to the manufacturer's own brochure, which is linked at the foot of the page, and each value is reproduced with the ASTM method it was measured to. Where the manufacturer publishes nothing for a property, this page says so instead of filling the gap. |
| You are converting a machine from mineral oil to an ester | The manufacturer's own warning is that residual mineral oil can make up as much as 10 percent of the charge after a drain-and-refill, which can foul the evaporator and cut efficiency. The changeover is carried out as a changeover — drained, flushed and evacuated — rather than a top-up. Tell us what is coming out and what is going in, and we will confirm the procedure with the oil. |
| You need documentation for customs or for a tender | CE, CO, MSDS and transport certification are issued as standard documents with an export order. Tell us at the enquiry stage which certificate the destination requires and we compile the file with the quotation rather than after the shipment. |
| You are buying alongside other oils and want them on one order | Refrigeration oils are the core of our business, not the whole plant. The same lines produce air compressor oils, vacuum pump oils and general industrial lubricants, and a mixed enquiry can be quoted, packed and shipped together rather than split across suppliers. |
The point of this list is that the questions are answered before the order rather than after it. If you are unsure which of them applies to you, describe the system and we will tell you what we need.
Grade confirmation comes before pricing, because the Emkarate RL range separates its grades by measured viscosity and a wrong one is the mistake that costs a compressor. The sequence is the same whether you are buying one can or a full container:
If you already know the grade and only need a price, send the quantity and the destination port and we will quote directly.
CPI Fluid Engineering publishes a full typical-properties table for every grade in the Emkarate RL range, with the test method named against each value, and an approvals list that gives the compressor type and model each grade is approved for. The table below reproduces the published values for this grade. Where a property a buyer might expect is not published, this page says so rather than filling it in.

The test-method column is reproduced from the manufacturer's brochure. Where a figure is published under a specific method, the method is shown so the value can be traced to the published test rather than treated as a general property. The manufacturer adds that the typical values in the brochure are not intended for use in preparing specifications, and that additional information is available on request. It also states that the RL lubricants are not hazardous under 29 CFR 1910.1200. CPI Fluid Engineering has been developing synthetic lubricants for industry since 1971 and describes itself as the first producer of polyol ester lubricants developed specifically for environmentally safe refrigerants; it was among the companies that received the 1993 Stratospheric Ozone Protection Award from the US Environmental Protection Agency, and it is certified to ISO 9001 and ISO 14001.
CPI prints an approvals list that names the equipment manufacturer, the compressor type or model, and the Emkarate RL grade approved for it. These are the entries on that list that name Emkarate RL 220H. The manufacturer prints the list with a caveat, reproduced in full at the foot of the table, that it is a guide and that the OEM should always be consulted.
| Equipment manufacturer | Compressor type (model) | Approved grade |
|---|---|---|
| CARRIER | Screw | RL 220H |
| HANBELL | Screw (RA, RB & V series) | RL 170H, RL 220H |
| McQUAY (J&E Hall) | Screw | RL 68H, RL 68HB, RL 100H, RL 220H |
| SABROE | Screw | RL 68H, RL 100H, RL 170H, RL 220H |
| VATANU-COOL | Orbital vane rotary (OVR) | RL 220H |
The manufacturer prints its approvals list with the caveat that it should be used as a guide only, that users should confirm with the original equipment manufacturer which grade is qualified for a particular combination of compressor model, refrigerant and application, and that OEM advice should always be taken and only approved lubricants used. The same list also approves other Emkarate designations that carry the same number but are separate product codes. Those are reproduced as printed and are not treated as Emkarate RL 220H on this page.
The Emkarate RL range is a set of POE grades separated by measured viscosity, from RL 5H+ at the light end to RL 220H at the heavy end. The manufacturer publishes the same typical-properties table for every grade, and an approvals list that shows how each one is used. The table shows the range as published, with this product marked.
| Grade | Viscosity at 40 °C (cSt) | Viscosity index | ISO 3448 position | Named in the approvals list for |
|---|---|---|---|---|
| RL 5H+ | 5.8 | 1.9 | Between the ISO VG 5 and ISO VG 7 bands | Not named in the manufacturer’s approvals list |
| RL 7H | 7.2 | 2.3 | ISO VG 7 (6.12–7.48 cSt) | Not named in the manufacturer’s approvals list |
| RL 10H | 9.7 | 2.7 | ISO VG 10 (9.0–11.0 cSt) | Not named in the manufacturer’s approvals list |
| RL 15H | 15.1 | 3.6 | ISO VG 15 (13.5–16.5 cSt) | Not named in the manufacturer’s approvals list |
| RL 22H | 18.9 | 4.2 | Between the ISO VG 15 and ISO VG 22 bands | BOCK, CARRIER TRANSICOLD, DORIN, JIANGSU XUEMEI, TECUMSEH |
| RL 32H | 32.5 | 5.8 | ISO VG 32 (28.8–35.2 cSt) | BITZER, BOCK, CARRIER, DALIAN BINGSHAN, DANFOSS COMMERCIAL (MANEUROP), DORIN and others |
| RL 46H | 45.3 | 7.1 | ISO VG 46 (41.4–50.6 cSt) | BOCK, DORIN, ROLTEC, SABROE |
| RL 68H | 66.6 | 9.4 | ISO VG 68 (61.2–74.8 cSt) | BITZER, BLISSFIELD, BOCK, CARRIER, CARRIER CARLYLE, DORIN and others |
| RL 100H | 96.5 | 11.3 | ISO VG 100 (90–110 cSt) | BOCK, GRASSO (GEA), McQUAY (J&E Hall), SABROE |
| RL 170H | 170 | 17.0 | Between the ISO VG 150 and ISO VG 220 bands | BITZER, DALIAN BINGSHAN, FRASCOLD, HANBELL, ROLTEC, SABROE |
| RL 220H (this product) | 215 | 18.8 | ISO VG 220 (198–242 cSt) | CARRIER, HANBELL, McQUAY (J&E Hall), SABROE, VATANU-COOL |
Viscosities and viscosity indices are reproduced from the manufacturer's brochure. The ISO 3448 position is derived from the published 40 °C value against the bands defined by that standard. Three grades in the range — RL 5H+, RL 22H and RL 170H — have published values that fall between two bands rather than inside one, so no class number is assigned to them; that is a property of the published figures, not an omission on this page.
If this grade is not the one you need, the sections below show where it sits against the rest of the Emkarate RL range and against the oils we manufacture ourselves, so a substitution can be checked before it is ordered.
| Brand | Grade | Viscosity at 40 °C | Note |
|---|---|---|---|
| Qishanr | QSL-220H | 215 cSt — our own ISO VG 220 grade | Our own equivalent, blended in Foshan, China, and named here rather than described: QSL-220H |
| Emkarate / CPI | Emkarate RL range | 5.8 to 215 cSt across the range | The full published range from the same manufacturer; Emkarate RL 220H is the heaviest grade of the Emkarate RL range |
| Emkarate / CPI | Emkarate RL 170H | 170 cSt, between two ISO classes | Another grade in the same range, published at its own measured viscosity |
| Emkarate / CPI | Emkarate RL 100H | ISO VG 100 at 96.5 cSt | Another grade in the same range, published at its own measured viscosity |
A substitution should be made on the measured viscosity at 40 °C and on the base oil type, not on the brand name alone. Where the manufacturer's published value falls between two ISO classes, the measured value is the only figure that can be compared.
ISO 3448 does not define a continuous scale of viscosity. It defines a series of discrete classes, each a band of permitted viscosity at 40 °C — the ISO VG 220 band (198–242 cSt) is the band this grade is assigned to — and a grade is assigned to a class from its measured figure.
CPI publishes 215 cSt at 40 °C for Emkarate RL 220H to ASTM D445, and that value falls inside the ISO VG 220 band (198–242 cSt), so the grade corresponds to ISO VG 220 and that is the class quoted on this page. What a buyer should match, in the end, is the measured 40 °C figure: it is the figure the compressor documentation specifies, and it is the figure the oil manufacturer publishes.
The viscosity is chosen from the compressor duty, not from the drum size. The Emkarate RL range separates its grades by measured viscosity, and Emkarate RL 220H is published at 215 cSt. A heavier oil forms a thicker film in the bearings and carries more load; a lighter oil returns to the sump more readily at low temperature and costs less energy to circulate. Both directions have a cost when the grade does not match the machine: step up and the compressor works against a film it was not designed for, step down and the film thins under load.
The figure to work from is the compressor manufacturer's requirement and the grade in the Emkarate RL range that matches it. That is the point at which we confirm the grade against the published data before quoting, and it is also why the same range carries more than one grade for what looks like the same duty.
The approvals list is the most useful page in the manufacturer's brochure for a buyer, because it names the compressor type and model each grade is approved for rather than describing the oil in general terms. It is also the page most easily over-read: an entry means the manufacturer approves that grade for that machine, not that the grade is interchangeable with every other grade in the range.
So the list is reproduced here with the manufacturer's own caveat attached — that it is a guide only, that the user should confirm with the OEM which grade is qualified for a particular combination of compressor model, refrigerant and application, that OEM advice should always be taken, and that only approved lubricants should be used. Where the list names a designation that is not this grade, such as the RL 32-3MAF, RL 32CF and RL 22CF variants, it is reproduced as printed rather than folded into this grade.
Every figure on this page comes from a document published by the brand owner, and every value is reproduced with the test method it was measured to — ASTM D445 for viscosity, D2270 for viscosity index, D97 for pour point, D1298 for density, D92 for flash point and D974 for acid value. That matters in a product category where values circulate between suppliers: a figure quoted without its method cannot be checked.
It also means a figure can be corrected against the source rather than repeated. The manufacturer adds that the typical values in the brochure are not intended for use in preparing specifications, and that additional information is available on request. It also states that the RL lubricants are not hazardous under 29 CFR 1910.1200. Every value here is either the manufacturer's own or, where the manufacturer publishes nothing for a property, a statement that no figure is published — so nothing here rests on a second-hand number.
The Emkarate RL range is a polyol ester range, and the reason is the refrigerant. The manufacturer states that an HFC system performs best when the lubricant and the refrigerant form a single clear phase — that is, when they are miscible — because miscibility lowers the viscosity of the oil carried through the system and lets it return to the compressor. Mineral oils are not miscible with HFCs; the Emkarate RL range is described as specially designed for enhanced miscibility. That is why an ester is specified for HFC duty where a mineral oil would leave the oil stranded in the evaporator, and it is why a mineral charge cannot simply be topped up with an ester.
The same chemistry carries a cost, and the manufacturer states it: an ester absorbs moisture, and moisture in an ester charge promotes hydrolysis and the formation of acids. On retrofit, the manufacturer warns that after a mineral-oil charge is drained and replaced with an ester, residual mineral oil can make up as much as 10 percent of the lubricant charge, which can severely affect miscibility, foul or coat the evaporator and reduce efficiency to unacceptable levels. Its instruction is therefore to remove as much mineral oil as possible and to follow its published retrofit procedure. Both points are on this page because both decide whether the grade works in the machine it is going into.
Thermal stability is reported from sealed-tube results to ASHRAE-97, which the manufacturer says show excellent stability in the presence of HFC refrigerants, with no adverse effects on metals and other materials of construction. That is the property a buyer is paying for when a system is specified on an ester rather than on a mineral or alkylbenzene oil.
We manufacture lubricants at our own blending plant in Foshan, Guangdong, which runs at 6,000 tonnes a year and has been producing for more than ten years. That is what allows us to quote a polyol ester at this published viscosity from our own line (our QSL-220H) against the Emkarate RL specification, and to hold stock on the grades we list rather than promising on behalf of a third party.
It also means the answer to a question about the oil comes from the plant rather than from an intermediary. If you need the grade matched to a compressor model, or to know which documents come with the shipment, tell us at the enquiry stage and we will confirm it against your destination rather than leave it until the order is placed.
Alongside the refrigeration oils the same plant produces air compressor oils, vacuum pump oils and general industrial lubricants, so a mixed enquiry can be quoted, packed and shipped as one shipment rather than split across suppliers.
A: There is no fixed minimum order — it is confirmed per order, because it depends on the pack size, the quantity and the destination, and a single can and a full container load are both workable. The manufacturer states that the RL range is available in a variety of packages, without listing pack sizes grade by grade. Custom pack formats and private-label artwork are available as a quotation item, so if your own label has to go on the container, say so when you enquire and it is quoted as part of the project rather than added afterwards.
A: Emkarate RL 220H is a polyol ester (POE) refrigeration and air-conditioning lubricant in the Emkarate RL range made by CPI Fluid Engineering, part of The Lubrizol Corporation. The manufacturer lists it for screw compressors and orbital vane rotary compressors on the OEM approvals published for this grade. It is published at 215 cSt at 40 °C, inside the ISO VG 220 band (198–242 cSt), so it is the ISO VG 220 grade of the range. The range is described by its manufacturer as synthetic polyol esters (POE) formulated specifically for refrigeration and air-conditioning compressors using HFC refrigerants, suitable for both initial fill and service fill, and combining low-temperature characteristics with chemical and thermal stability over wide operating temperature ranges.
A: The manufacturer publishes 215 cSt at 40 °C to ASTM D445 and 18.8 cSt at 100 °C to ASTM D445, with a viscosity index of 98 to ASTM D2270. The 40 °C figure falls inside the ISO VG 220 band (198–242 cSt), so the grade is the ISO VG 220 grade.
A: The range is formulated for HFC refrigerants. The manufacturer states that an HFC system performs best when the lubricant and the refrigerant form a single clear phase — that is, when they are miscible — because miscibility lowers the viscosity of the oil carried through the system and lets it return to the compressor. Mineral oils are not miscible with HFCs; the Emkarate RL range is described as specially designed for enhanced miscibility. The manufacturer's approvals list separates the grades by compressor type and model rather than by refrigerant, so send us the model, the refrigerant and the application and we will confirm the grade against the published table.
A: Yes. The manufacturer publishes 215 cSt at 40 °C for this grade to ASTM D445, and that value falls inside the ISO VG 220 band (198–242 cSt), so the grade corresponds to ISO VG 220. Match on the measured 40 °C figure as well, because that is what the compressor documentation specifies.
A: Both are polyol ester grades in the same Emkarate RL range but at different measured viscosities. Emkarate RL 220H is published at 215 cSt at 40 °C, while Emkarate RL 170H is published at 170 cSt. The manufacturer names different equipment manufacturers and compressor types for the two, so they are not interchangeable even where the applications overlap. Send us the compressor model and the nameplate oil type and we will confirm which of the two matches the machine.
A: The manufacturer's approvals list names CARRIER, HANBELL, McQUAY (J&E Hall), SABROE, VATANU-COOL for this grade. The manufacturer prints its approvals list with the caveat that it should be used as a guide only, that users should confirm with the original equipment manufacturer which grade is qualified for a particular combination of compressor model, refrigerant and application, and that OEM advice should always be taken and only approved lubricants used. The full list for this grade is reproduced in the approvals table above, with the compressor type or model against each manufacturer.
A: No, and with an ester the point is sharper than usual. Mineral oil is not miscible with HFC refrigerants, which is why the ester is specified in the first place; adding mineral oil to an ester charge defeats that. On retrofit, the manufacturer warns that after a mineral-oil charge is drained and replaced with an ester, residual mineral oil can make up as much as 10 percent of the lubricant charge, which can severely affect miscibility, foul or coat the evaporator and reduce efficiency to unacceptable levels. Its instruction is therefore to remove as much mineral oil as possible and to follow its published retrofit procedure. Where a machine is being changed over, the old charge is drained and the circuit flushed and evacuated rather than topped up.
A: Store it sealed, away from direct sunlight, and keep the container closed between top-ups. A polyol ester absorbs moisture from the air, and moisture is what shortens its service life: at high temperature, in the presence of the ester and the refrigerant, water promotes hydrolysis and the formation of acids. The container should be resealed after every use and the oil should not be decanted into an unlined steel drum where it can pick up rust and moisture.
A: Yes. Private-label artwork and custom pack formats are a normal quotation item, and the container is packed at our plant in Foshan. Tell us at the enquiry stage that your own label is required, and the artwork and the pack are quoted together with the oil rather than added afterwards.
A: The manufacturer states that the Emkarate RL lubricants are not hazardous under 29 CFR 1910.1200. The technical data sheet and safety data sheet come with the quotation, and a certificate of analysis for the delivered batch comes with the shipment.

This oil is manufactured and supplied by Guangzhou Qishanr Technologies Co., Ltd., trading as the brand QISHANR. The company is based in Foshan, Guangdong, adjacent to Guangzhou Port, and has been producing lubricants for more than 10 years from its own blending plant. That plant runs at an annual capacity of 6,000 tonnes, which is what allows us to hold stock on the grades we list and quote firm lead times rather than promising on behalf of a third party.
Refrigeration oils are the core of the business, but they are not the whole plant. The same lines produce general industrial lubricants, so a mixed enquiry that covers both refrigeration oils and ordinary industrial grades can be quoted, packed and shipped together instead of being split across suppliers.
This is not the full range. Specialised ester base oils and lubricant additives are produced in-house as well, which is the reason the synthetic ester grades can be specified to a target rather than bought off a shelf. If the grade you need is not listed above, send the specification or the product you are replacing and we will confirm whether we produce it.
Long-term partners get pricing that reflects a stable manufacturing base rather than a trading margin, and the same technical contact stays with the account from grade selection through to repeat orders.
Emkarate RL 220H is quoted on the grade, the pack size and the destination port rather than on a list price. Send your compressor model, the refrigerant, the oil type on the nameplate and the quantity you need. We will confirm the grade against the manufacturer's published data — including whether your machine takes this grade or the one next to it — and come back with pricing, pack size and lead time. A technical data sheet and safety data sheet come with the quotation, and we can quote our own equivalent side by side so the comparison is on landed cost.
